分散式專案和傳統專案的區別就是，分散式專案有多個服務，每一個服務僅僅只實現一套系統中一個或幾個功能，所有的服務組合在一起才能實現系統的完整功能。這會產生一個問題，多個服務之間session不能共享，你在其中一個服務中登入了，登入資訊儲存在這個服務的session中，別的服務不知道啊，所以你訪問別的服務還得在重新登入一次，對使用者十分不友好。為了解決這個問題，於是就產生了單點登入：

**jwt單點登入：**就是使用者在登入服務登入成功後，登入服務會產生向前端響應一個token（令牌），以後使用者再訪問系統的資源的時候都要帶上這個令牌，各大服務對這個令牌進行驗證（令牌是否過期，令牌是否被篡改），驗證通過了，可以訪問資源，同時，令牌中也會攜帶一些不重要的資訊，比如使用者名稱，許可權。通過解析令牌就能知道當前登入的使用者和使用者所擁有的許可權。

下面我們就來寫一個案例專案看看具體如何使用

1 建立專案結構

1.1 父工程cloud-security

這是父工程所需要的包

 <artifactId>lombok</artifactId>
</dependency>

<dependency>
 <groupId>com.alibaba</groupId>
 <artifactId>fastjson</artifactId>
 <version>1.2.60</version>

 <version>0.11.2</version>
 <scope>runtime</scope>
</dependency>

1.3 認證服務security-sever

這個服務僅僅只有兩項功能：

（1）使用者登入，頒發令牌

（2）使用者註冊

我們這裡只實現第一個功能

1.3.1 認證服務所需的包

<dependency>
 <groupId>cn.lx.security</groupId>
 <artifactId>security-common</artifactId>
 <version>1.0-SNAPSHOT</version>
</dependency>

<dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
</dependency>
<!--通用mapper-->
<dependency>
 <groupId>tk.mybatis</groupId>
 <artifactId>mapper-spring-boot-starter</artifactId>
 <version>2.0.4</version>
</dependency>

<dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

1.3.2 配置application.yml

這裡面的配置沒什麼好說的，都很簡單

server:
 port: 8080

spring:
 datasource:
 url: jdbc:mysql:///security_authority?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC
 username: root
 password:
 driver-class-name: com.mysql.cj.jdbc.Driver
 thymeleaf:
 cache: false
 main:
 allow-bean-definition-overriding: true


mybatis:
 type-aliases-package: cn.lx.security.doamin
 configuration:
 #駝峰
 map-underscore-to-camel-case: true

logging:
 level:
 cn.lx.security: debug

1.3.3 匯入domain,dao,service，config

這個可以在上篇文件中找到，我們只需要service中的loadUserByUsername方法及其所呼叫dao中的方法

完整專案在我的github中，地址：[email protected]:lx972/cloud-security.git

配置檔案我們也從上篇中複製過來MvcConfig，SecurityConfig

1.3.4 測試

訪問http://localhost:8080/loginPage成功出現登入頁面，說明認證服務的骨架搭建成功了

1.4 資源服務security-resource1

實際專案中會有很多資源服務，我只演示一個

為了簡單，資源服務不使用資料庫

1.4.1 資源服務所需的包

<dependency>
 <groupId>cn.lx.security</groupId>
 <artifactId>security-common</artifactId>
 <version>1.0-SNAPSHOT</version>
</dependency>

1.4.2 配置application.yml

server:
 port: 8090

logging:
 level:
 cn.lx.security: debug

1.4.3 controller

擁有ORDER_LIST許可權的才能訪問

@RestController
@RequestMapping("/order")
public class OrderController {

 //@Secured("ORDER_LIST")
 @PreAuthorize(value = "hasAuthority('ORDER_LIST')")
 @RequestMapping("/findAll")
 public String findAll(){
  return "order-list";
 }
}

擁有PRODUCT_LIST許可權的才能訪問

@RestController
@RequestMapping("/product")
public class ProductController {

 //@Secured("PRODUCT_LIST")
 @PreAuthorize(value = "hasAuthority('PRODUCT_LIST')")
 @RequestMapping("/findAll")
 public String findAll(){
  return "product-list";
 }
}

1.4.4 security配置類

@Configuration
@EnableWebSecurity
//這個註解先不要加
//@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 
 /**
  * Override this method to configure the {@link HttpSecurity}. Typically subclasses
  * should not invoke this method by calling super as it may override their
  * configuration. The default configuration is:
  *
  * <pre>
  * http.authorizeRequests().anyRequest().authenticated().and().formLogin().and().httpBasic();
  * </pre>
  *
  * @param http the {@link HttpSecurity} to modify
  * @throws Exception if an error occurs
  */
 @Override
 protected void configure(HttpSecurity http) throws Exception {
  http
    .csrf().disable()
    .authorizeRequests().anyRequest().authenticated();
 }
}

1.4.5 測試

訪問http://localhost:8090/order/findAll成功打印出order-list，服務搭建成功。

2 認證服務實現登入，頒發令牌

首先，我們必須知道我們的專案是前後端分離的專案，所以我們不能由後端控制頁面跳轉了，只能返回json串通知前端登入成功，然後前端根據後端返回的資訊控制頁面跳轉。

2.1 登入成功或者登入失敗後的原始碼分析

UsernamePasswordAuthenticationFilter中登入成功後走successfulAuthentication方法

/**
	 * Default behaviour for successful authentication.認證成功之後的預設操作
	 * <ol>
	 * <li>Sets the successful <tt>Authentication</tt> object on the
	 * {@link SecurityContextHolder}</li>
	 * <li>Informs the configured <tt>RememberMeServices</tt> of the successful login</li>
	 * <li>Fires an {@link InteractiveAuthenticationSuccessEvent} via the configured
	 * <tt>ApplicationEventPublisher</tt></li>
	 * <li>Delegates additional behaviour to the {@link AuthenticationSuccessHandler}.</li>
	 * </ol>
	 *
	 * Subclasses can override this method to continue the {@link FilterChain} after
	 * successful authentication.
	 * @param request
	 * @param response
	 * @param chain
	 * @param authResult the object returned from the <tt>attemptAuthentication</tt>
	 * method.
	 * @throws IOException
	 * @throws ServletException
	 */
	protected void successfulAuthentication(HttpServletRequest request,HttpServletResponse response,FilterChain chain,Authentication authResult)
			throws IOException,ServletException {

		if (logger.isDebugEnabled()) {
			logger.debug("Authentication success. Updating SecurityContextHolder to contain: "
					+ authResult);
		}

  //將已通過認證的Authentication儲存到securityContext容器中，應為後面的過濾器需要使用
		SecurityContextHolder.getContext().setAuthentication(authResult);

  //記住我
		rememberMeServices.loginSuccess(request,response,authResult);

		// Fire event
		if (this.eventPublisher != null) {
			eventPublisher.publishEvent(new InteractiveAuthenticationSuccessEvent(
					authResult,this.getClass()));
		}

  //這個方法你點進去，就會發現，真正作業面跳轉是在這裡
		successHandler.onAuthenticationSuccess(request,authResult);
	}

UsernamePasswordAuthenticationFilter中登入成功後走unsuccessfulAuthentication方法

/**
	 * Default behaviour for unsuccessful authentication.認證失敗之後的預設操作
	 * <ol>
	 * <li>Clears the {@link SecurityContextHolder}</li>
	 * <li>Stores the exception in the session (if it exists or
	 * <tt>allowSesssionCreation</tt> is set to <tt>true</tt>)</li>
	 * <li>Informs the configured <tt>RememberMeServices</tt> of the failed login</li>
	 * <li>Delegates additional behaviour to the {@link AuthenticationFailureHandler}.</li>
	 * </ol>
	 */
	protected void unsuccessfulAuthentication(HttpServletRequest request,AuthenticationException failed)
			throws IOException,ServletException {
		SecurityContextHolder.clearContext();

		if (logger.isDebugEnabled()) {
			logger.debug("Authentication request failed: " + failed.toString(),failed);
			logger.debug("Updated SecurityContextHolder to contain null Authentication");
			logger.debug("Delegating to authentication failure handler " + failureHandler);
		}

  //記住我失敗
		rememberMeServices.loginFail(request,response);

  //失敗後的頁面跳轉都在這裡
		failureHandler.onAuthenticationFailure(request,failed);
	}

2.2 重寫successfulAuthentication和unsuccessfulAuthentication方法

我們繼承UsernamePasswordAuthenticationFilter這個過濾器

public class AuthenticationFilter extends UsernamePasswordAuthenticationFilter {

  /**
  * 這個方法必須有
  * 在過濾器建立的時候手動將AuthenticationManager物件給這個過濾器使用
  * @param authenticationManager 這個物件在自己寫的SecurityConfig裡面
  */
 public AuthenticationFilter(AuthenticationManager authenticationManager) {
  super.setAuthenticationManager(authenticationManager);
 }

 /**
  * Default behaviour for successful authentication.認證成功之後的預設操作
  * @param request
  * @param response
  * @param chain
  * @param authResult the object returned from the <tt>attemptAuthentication</tt>
  *     method.
  * @throws IOException
  * @throws ServletException
  */
 @Override
 protected void successfulAuthentication(HttpServletRequest request,Authentication authResult) throws IOException,ServletException {

  //認證成功的物件放入securityContext容器中
  SecurityContextHolder.getContext().setAuthentication(authResult);

  // Fire event
  if (this.eventPublisher != null) {
   eventPublisher.publishEvent(new InteractiveAuthenticationSuccessEvent(
     authResult,this.getClass()));
  }
  //建立令牌
  Map<String,Object> claims=new HashMap<>();
  SysUser sysUser = (SysUser) authResult.getPrincipal();
  claims.put("username",sysUser.getUsername());
  claims.put("authorities",authResult.getAuthorities());
  //這個方法在下面介紹
  String jwt = JwtUtil.createJwt(claims);
  //直接返回json
  ResponseUtil.responseJson(new Result("200","登入成功",jwt),response);
 }


 /**
  * Default behaviour for unsuccessful authentication.
  * @param request
  * @param response
  * @param failed
  */
 @Override
 protected void unsuccessfulAuthentication(HttpServletRequest request,AuthenticationException failed) throws IOException,ServletException {
   //清理容器中儲存的認證物件
  SecurityContextHolder.clearContext();
  //直接返回json
  ResponseUtil.responseJson(new Result("500","登入失敗"),response);

 }
}

2.3 令牌建立

String jwt = JwtUtil.createJwt(claims);

這個方法幹了什麼事呢

/**
  * 建立令牌
  * @param claims
  * @return
  */
public static String createJwt(Map<String,Object> claims){
 //獲取私鑰
 String priKey = KeyUtil.readKey("privateKey.txt");
 //將string型別的私鑰轉換成PrivateKey，jwt只能接受PrivateKey的私鑰
 PKCS8EncodedKeySpec priPKCS8 = null;
 try {
  priPKCS8 = new PKCS8EncodedKeySpec(new BASE64Decoder().decodeBuffer(priKey));
  KeyFactory keyf = KeyFactory.getInstance("RSA");
  PrivateKey privateKey = keyf.generatePrivate(priPKCS8);
  //建立令牌
  String jws = Jwts.builder()
   //設定令牌過期時間30分鐘
   .setExpiration(new Date(System.currentTimeMillis()+1000*60*30))
   //為令牌設定額外的資訊，這裡我們設定使用者名稱和許可權，還可以根據需要繼續新增
   .addClaims(claims)
   //指定加密型別為rsa
   .signWith(privateKey,SignatureAlgorithm.RS256)
   //得到令牌
   .compact();
  log.info("建立令牌成功："+jws);
  return jws;
 } catch (Exception e) {
  throw new RuntimeException("建立令牌失敗");
 }
}

獲取祕鑰的方法

public class KeyUtil {

 /**
  * 讀取祕鑰
  * @param keyName
  * @return
  */
 public static String readKey(String keyName){
  //檔案必須放在resources根目錄下
  ClassPathResource resource=new ClassPathResource(keyName);
  String key =null;
  try {
   InputStream is = resource.getInputStream();
   key = StreamUtils.copyToString(is,Charset.defaultCharset());
  }catch (Exception e){
   throw new RuntimeException("讀取祕鑰錯誤");
  }
  if (key==null){
   throw new RuntimeException("祕鑰為空");
  }
  return key;
 }
}

2.4 響應json格式資料給前端

封裝成了一個工具類

public class ResponseUtil {

 /**
  * 將結果以json格式返回
  * @param result 返回結果
  * @param response
  * @throws IOException
  */
 public static void responseJson(Result result,HttpServletResponse response) throws IOException {
  response.setContentType("application/json;charset=utf-8");
  response.setStatus(200);
  PrintWriter writer = response.getWriter();
  writer.write(JSON.toJSONString(result));
  writer.flush();
  writer.close();
 }
}

返回結果

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Result {

 private String code;
 private String msg;
 private Object data;

 public Result(String code,String msg) {
  this.code = code;
  this.msg = msg;
 }
}

3 認證服務實現令牌驗證和解析

除了security配置類中配置的需要忽略的請求之外，其他所有請求必須驗證請求頭中是否攜帶令牌，沒有令牌直接響應json資料，否則就驗證和解析令牌。

security中有一個過濾器是實現令牌BasicAuthenticationFilter認證的，只不過他是basic的，沒關係，我們繼承它，然後重寫解析basic的方法

3.1 原始碼分析

@Override
protected void doFilterInternal(HttpServletRequest request,FilterChain chain)
 throws IOException,ServletException {
 final boolean debug = this.logger.isDebugEnabled();

 //獲取請求頭中Authorization的值
 String header = request.getHeader("Authorization");

 if (header == null || !header.toLowerCase().startsWith("basic ")) {
  //值不符合條件直接放行
  chain.doFilter(request,response);
  return;
 }

 try {
  //就是解析Authorization
  String[] tokens = extractAndDecodeHeader(header,request);
  assert tokens.length == 2;

  //tokens[0]使用者名稱 tokens[1]密碼
  String username = tokens[0];

  if (debug) {
   this.logger
    .debug("Basic Authentication Authorization header found for user '"
      + username + "'");
  }

  //判斷是否需要認證（容器中有沒有該認證物件）
  if (authenticationIsRequired(username)) {
   //建立一個物件
   UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(
    username,tokens[1]);
   authRequest.setDetails(
    this.authenticationDetailsSource.buildDetails(request));
   //進行認證，我們不關心它如何認證，我們需要按自己的方法對令牌認證解析
   Authentication authResult = this.authenticationManager
    .authenticate(authRequest);

   if (debug) {
    this.logger.debug("Authentication success: " + authResult);
   }

   //已認證的物件儲存到securityContext中
   SecurityContextHolder.getContext().setAuthentication(authResult);

   //記住我
   this.rememberMeServices.loginSuccess(request,authResult);

   onSuccessfulAuthentication(request,authResult);
  }

 }
 catch (AuthenticationException failed) {
  SecurityContextHolder.clearContext();

  if (debug) {
   this.logger.debug("Authentication request for failed: " + failed);
  }

  this.rememberMeServices.loginFail(request,response);

  onUnsuccessfulAuthentication(request,failed);

  if (this.ignoreFailure) {
   chain.doFilter(request,response);
  }
  else {
   this.authenticationEntryPoint.commence(request,failed);
  }

  return;
 }

 chain.doFilter(request,response);
}

3.2 重寫doFilterInternal方法

繼承BasicAuthenticationFilter

public class TokenVerifyFilter extends BasicAuthenticationFilter {


 /**
  * Creates an instance which will authenticate against the supplied
  * {@code AuthenticationManager} and which will ignore failed authentication attempts,* allowing the request to proceed down the filter chain.
  * 在過濾器建立的時候手動將AuthenticationManager物件給這個過濾器使用
  * @param authenticationManager 這個物件在自己寫的SecurityConfig裡面
  */
 public TokenVerifyFilter(AuthenticationManager authenticationManager) {
  super(authenticationManager);
 }

 /**
  * 過濾請求，判斷是否攜帶令牌
  * @param request
  * @param response
  * @param chain
  * @throws IOException
  * @throws ServletException
  */
 @Override
 protected void doFilterInternal(HttpServletRequest request,FilterChain chain) throws IOException,ServletException {

  String header = request.getHeader("Authorization");

  if (header == null || !header.toLowerCase().startsWith("bearer ")) {
   //直接返回json
   ResponseUtil.responseJson(new Result("403","使用者未登入"),response);
   return;
  }

  //得到jwt令牌
  String jwt = StringUtils.replace(header,"bearer ","");
  //解析令牌
  String[] tokens = JwtUtil.extractAndDecodeJwt(jwt);

  //使用者名稱
  String username = tokens[0];
  //許可權
  List<SysPermission> authorities= JSON.parseArray(tokens[1],SysPermission.class);

  UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(
    username,null,authorities
    );

  //放入SecurityContext容器中
  SecurityContextHolder.getContext().setAuthentication(authRequest);

  chain.doFilter(request,response);
 }
}

3.3 驗證解析令牌

/**
  * 解析令牌
  * @param compactJws
  * @return
  */
public static String decodeJwt(String compactJws){
 //獲取公鑰
 String pubKey = KeyUtil.readKey("publicKey.txt");
 //將string型別的私鑰轉換成PublicKey，jwt只能接受PublicKey的公鑰
 KeyFactory keyFactory;
 try {
  X509EncodedKeySpec bobPubKeySpec = new X509EncodedKeySpec(
   new BASE64Decoder().decodeBuffer(pubKey));

  keyFactory = KeyFactory.getInstance("RSA");
  PublicKey publicKey = keyFactory.generatePublic(bobPubKeySpec);

  Claims body = Jwts.parserBuilder().setSigningKey(publicKey).build().parseClaimsJws(compactJws).getBody();

  String jwtString = JSON.toJSONString(body);

  //OK,we can trust this JWT
  log.info("解析令牌成功："+jwtString);
  return jwtString;
 } catch (Exception e) {
  throw new RuntimeException("解析令牌失敗");
 }
}


/**
  * 解析令牌並獲取使用者名稱和許可權
  * @param compactJws
  * @return String[0]使用者名稱
  * String[1]許可權
  */
public static String[] extractAndDecodeJwt(String compactJws){
 //獲取令牌的內容
 String decodeJwt = decodeJwt(compactJws);
 JSONObject jsonObject = JSON.parseObject(decodeJwt);
 String username = jsonObject.getString("username");
 String authorities = jsonObject.getString("authorities");
 return new String[] { username,authorities };
}

3.4 修改security配置類

將自定義過濾器加入過濾器鏈

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

 @Autowired
 private IUserService iUserService;

 @Autowired
 private BCryptPasswordEncoder bCryptPasswordEncoder;

 /**
  * 只有這個配置類有AuthenticationManager物件，我們要把這個類中的這個物件放入容器中
  * 這樣在別的地方就可以自動注入了
  * @return
  * @throws Exception
  */
 @Bean
 @Override
 public AuthenticationManager authenticationManager() throws Exception {
  AuthenticationManager authenticationManager = super.authenticationManagerBean();
  return authenticationManager;
 }

 /**
  * Used by the default implementation of {@link #authenticationManager()} to attempt
  * to obtain an {@link AuthenticationManager}. If overridden,the
  * {@link AuthenticationManagerBuilder} should be used to specify the
  * {@link AuthenticationManager}.
  *
  * <p>
  * The {@link #authenticationManagerBean()} method can be used to expose the resulting
  * {@link AuthenticationManager} as a Bean. The {@link #userDetailsServiceBean()} can
  * be used to expose the last populated {@link UserDetailsService} that is created
  * with the {@link AuthenticationManagerBuilder} as a Bean. The
  * {@link UserDetailsService} will also automatically be populated on
  * {@link HttpSecurity#getSharedObject(Class)} for use with other
  * {@link SecurityContextConfigurer} (i.e. RememberMeConfigurer )
  * </p>
  *
  * <p>
  * For example,the following configuration could be used to register in memory
  * authentication that exposes an in memory {@link UserDetailsService}:
  * </p>
  *
  * <pre>
  * &#064;Override
  * protected void configure(AuthenticationManagerBuilder auth) {
  * 	auth
  * 	// enable in memory based authentication with a user named
  * 	// &quot;user&quot; and &quot;admin&quot;
  * 	.inMemoryAuthentication().withUser(&quot;user&quot;).password(&quot;password&quot;).roles(&quot;USER&quot;).and()
  * 			.withUser(&quot;admin&quot;).password(&quot;password&quot;).roles(&quot;USER&quot;,&quot;ADMIN&quot;);
  * }
  *
  * // Expose the UserDetailsService as a Bean
  * &#064;Bean
  * &#064;Override
  * public UserDetailsService userDetailsServiceBean() throws Exception {
  * 	return super.userDetailsServiceBean();
  * }
  *
  * </pre>
  *
  * @param auth the {@link AuthenticationManagerBuilder} to use
  * @throws Exception
  */
 @Override
 protected void configure(AuthenticationManagerBuilder auth) throws Exception {
  //在記憶體中註冊一個賬號
  //auth.inMemoryAuthentication().withUser("user").password("{noop}123").roles("USER");
  //連線資料庫，使用資料庫中的賬號
  auth.userDetailsService(iUserService).passwordEncoder(bCryptPasswordEncoder);


 }

 /**
  * Override this method to configure {@link WebSecurity}. For example,if you wish to
  * ignore certain requests.
  *
  * @param web
  */
 @Override
 public void configure(WebSecurity web) throws Exception {
  web.ignoring().antMatchers("/css/**","/img/**","/plugins/**","/favicon.ico","/loginPage");
 }

 /**
  * Override this method to configure the {@link HttpSecurity}. Typically subclasses
  * should not invoke this method by calling super as it may override their
  * configuration. The default configuration is:
  *
  * <pre>

  * </pre>
  *
  * @param http the {@link HttpSecurity} to modify
  * @throws Exception if an error occurs
  */
 @Override
 protected void configure(HttpSecurity http) throws Exception {
  http.csrf().disable()
    .httpBasic()
    .and()
    .authorizeRequests()
    .anyRequest().authenticated()
    .and()
    /**
     * 不要將自定義過濾器加component註解，而是在這裡直接建立一個過濾器物件加入到過濾器鏈中，並傳入authenticationManager
     * 啟動後，過濾器鏈中會同時出現自定義過濾器和他的父類，他會自動覆蓋，並不會過濾兩次
     *
     * 使用component註解會產生很多問題：
     * 1. web.ignoring()會失效，上面的資源還是會經過自定義的過濾器
     * 2.過濾器鏈中出現的是他們父類中的名字
     * 3.登入的時候（訪問/login），一直使用匿名訪問，不會去資料庫中查詢
     */
    .addFilterAt(new AuthenticationFilter(super.authenticationManager()),UsernamePasswordAuthenticationFilter.class)
    .addFilterAt(new TokenVerifyFilter(super.authenticationManager()),BasicAuthenticationFilter.class)
    //.formLogin().loginPage("/login.jsp").loginProcessingUrl("/login").defaultSuccessUrl("/index.jsp").failureForwardUrl("/failer.jsp").permitAll()
    .formLogin().loginPage("/loginPage").loginProcessingUrl("/login").permitAll()
    .and()
    .logout().logoutUrl("/logout").logoutSuccessUrl("/loginPage").invalidateHttpSession(true).permitAll();
 }
}

4 資源服務實現令牌驗證和解析

複製認證服務的TokenVerifyFilter到資源服務

然後修改security的配置檔案

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
 /**
  * Override this method to configure the {@link HttpSecurity}. Typically subclasses
  * should not invoke this method by calling super as it may override their
  * configuration. The default configuration is:
  *
  * <pre>
  * http.authorizeRequests().anyRequest().authenticated().and().formLogin().and().httpBasic();
  * </pre>
  *
  * @param http the {@link HttpSecurity} to modify
  * @throws Exception if an error occurs
  */
 @Override
 protected void configure(HttpSecurity http) throws Exception {
  http
    .csrf().disable()
    .authorizeRequests().anyRequest().authenticated()
    .and()
    //禁用session
    .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
    .and()
   //新增自定義過濾器
    .addFilterAt(new TokenVerifyFilter(super.authenticationManager()),BasicAuthenticationFilter.class);
 }
}
