一、ResourceServer（資源伺服器）

application.yml

server:
  port: 8082
  context-path: /resourceserver

啟動類

@SpringBootApplication
public class ResourceServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ResourceServerApplication.class, args);
    }
}

TestController.java（暴露RESTful介面）

@RestController
public class TestController {

    @GetMapping("/product/{id}")
    public String product(@PathVariable String id) {
        return "product id : " + id;
    }

    @GetMapping("/order/{id}")
    public String order(@PathVariable String id) {
        return "order id : " + id;
    }

    @GetMapping("/pomer/{id}")
    public String pomer(@PathVariable String id) {
        return "pomer id : " + id;
    }
}
 

配置類 ResourceServerConfig（配置JWT形式的token）

@EnableResourceServer
@Configuration
public class ResourceServerConfig {

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey("123");
        return converter;
    }
}

配置類 MyResourceServerConfigurer（配置訪問許可權）

@Configuration
public class MyResourceServerConfigurer extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/product/**").permitAll()
                .antMatchers("/order/**").authenticated()
                .antMatchers("/pomer/**").access("#oauth2.hasScope('read_profile') and hasAuthority('ADMIN')");
    }
}

二、AuthorizationServer 授權伺服器（授權碼模式，authorization code）

application.yml

server:
  port: 8081
  context-path: /authorizationserver

啟動類

@SpringBootApplication
public class AuthorizationServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(AuthorizationServerApplication.class, args);
    }
}

配置類 AuthorizationServerConfig（配置JWT形式的token）

@EnableAuthorizationServer
@Configuration
public class AuthorizationServerConfig {

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey("123");
        return converter;
    }
}

配置類 MyAuthorizationServerConfigurer

@Configuration
public class MyAuthorizationServerConfigurer extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private TokenStore tokenStore;
    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.tokenStore(tokenStore)
                .accessTokenConverter(jwtAccessTokenConverter)
                .authenticationManager(authenticationManager);
    }

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("clientApp")
                .secret("123456")
                .redirectUris("http://localhost:9000/callback")
                .authorizedGrantTypes("authorization_code")
                .scopes("read_profile", "read_contacts");
    }
}

配置類 MyWebSecurityConfigurerAdapter（配置使用者名稱密碼）

@Configuration
public class MyWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("user").password("123456").authorities("USER").and()
                .withUser("admin").password("123456").authorities("USER", "ADMIN");
    }
}

開始測試！開啟瀏覽器訪問:

http://localhost:8081/authorizationserver/oauth/authorize?client_id=clientApp&redirect_uri=http://localhost:9000/callback&response_type=code&scope=read_profile

顯示登入頁面，輸入使用者名稱密碼，返回重定向302（授權碼位於引數部分）

http://localhost:9000/callback?code=EWfpi5

根據授權碼，請求令牌：

>  curl -X POST --user clientApp:123456 http://localhost:8081/authorizationserver/oauth/token -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=authorization_code&redirect_uri=http://localhost:9000/callback&scope=read_profile&code=EWfpi5"

# clientApp:123456 經Base64編碼得 'Y2xpZW50QXBwOjEyMzQ1Ng=='
POST /authorizationserver/oauth/token HTTP/1.1
Host: localhost:8081
Content-Type: application/x-www-form-urlencoded

code=F4QesT&grant_type=authorization_code&redirect_uri=http%3A%2F%2Flocalhost%3A9000%2Fcallback&scope=read_profile

得到令牌：

}

根據令牌請求資源

返回資源

order id : 12

附：/product/* 允許任何人訪問，/order/* 需要使用者認證，而 /pomer/* 只允許擁有ADMIN許可權的admin使用者訪問，測試有效

三、AuthorizationServer 授權伺服器（簡化模式，implicit）

只修改配置類 MyAuthorizationServerConfigurer，其餘程式碼不變

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("clientApp")
                .secret("123456")
                .redirectUris("http://localhost:9000/callback")
                .authorizedGrantTypes("implicit")
                .scopes("read_profile","read_contacts");
    }

開始測試！開啟瀏覽器訪問：

http://localhost:8081/authorizationserver/oauth/authorize?client_id=clientApp&redirect_uri=http://localhost:9000/callback&response_type=token&scope=read_profile&state=xyz

顯示登入頁面，輸入使用者名稱密碼，返回重定向302（令牌位於hash部分）：

http://localhost:9000/callback#access_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NDE4NjMxNjMsInVzZXJfbmFtZSI6InVzZXIiLCJhdXRob3JpdGllcyI6WyJVU0VSIl0sImp0aSI6ImQ2MzYxYzZjLTIyZWYtNDU2ZC1iOGJhLWY4ZTE5MzMwMTBmOSIsImNsaWVudF9pZCI6ImNsaWVudEFwcCIsInNjb3BlIjpbInJlYWRfcHJvZmlsZSJdfQ.BRwtzF2rFc6w8WECqYETZbkCSDdoOzKdF4Zm_SAZuao&token_type=bearer&state=xyz&expires_in=119&jti=d6361c6c-22ef-456d-b8ba-f8e1933010f9

得到令牌，後續請求資源相同，不再重複敘述

四、AuthorizationServer 授權伺服器（密碼模式，resource owner password credentials）

修改配置類 MyAuthorizationServerConfigurer

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("clientApp")
                .secret("123456")
                .authorizedGrantTypes("password")
                .scopes("read_profile", "read_contacts");
    }

在預設情況下 AuthorizationServerEndpointsConfigurer 配置沒有開啟密碼模式，只有配置了 authenticationManager 才會開啟密碼模式，如下

在 MyWebSecurityConfigurerAdapter.java 新增一段程式碼（配置 authenticationManager Bean）

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

在 MyAuthorizationServerConfigurer.java 新增一段程式碼（令 AuthorizationServerEndpointsConfigurer 設定 authenticationManager）

    @Autowired
    private AuthenticationManager authenticationManager;
    @Autowired
    private TokenStore tokenStore;
    @Autowired
    private JwtAccessTokenConverter jwtAccessTokenConverter;

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) {
        endpoints.tokenStore(tokenStore)
                .accessTokenConverter(jwtAccessTokenConverter)
                .authenticationManager(authenticationManager);
    }

開始測試！請求令牌

>  curl -X POST --user clientApp:123456 http://localhost:8081/authorizationserver/oauth/token -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=password&scope=read_profile&username=user&password=123456"

得到令牌：

{
"access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1NDE5MDk4MTcsInVzZXJfbmFtZSI6InVzZXIiLCJhdXRob3JpdGllcyI6WyJVU0VSIl0sImp0aSI6ImJhZDk1OTI0LTdkYTgtNDUyMy05YzZkLTBkNzY3NTlmYjQ1NiIsImNsaWVudF9pZCI6ImNsaWVudEFwcCIsInNjb3BlIjpbInJlYWRfcHJvZmlsZSJdfQ.gO5_kl8_OBRnj2Dt5glflXAIJrbyioYXezV-ZQ8BxL4",

"expires_in":43199,
"scope":"read_profile",
"jti":"bad95924-7da8-4523-9c6d-0d76759fb456"
}

得到令牌，後續請求資源相同，不再重複敘述

五、AuthorizationServer 授權伺服器（客戶端模式，client credentials）

只修改配置類 MyAuthorizationServerConfigurer，其餘程式碼不變

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("clientApp")
                .secret("123456")
                .authorizedGrantTypes("client_credentials")
                .scopes("read_profile", "read_contacts");
    }

開始測試！請求令牌

>  curl -X POST --user clientApp:123456 http://localhost:8081/authorizationserver/oauth/token -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=client_credentials&scope=read_profile"

}
