我們開發時候有時候要把傳統spring shiro轉成spring boot專案，或者直接整合，那麼我們要搞清楚一個知識，就是 xml配置和spring bean程式碼配置的關係，這一點很重要，因為spring boot是沒有xml配置檔案的(也不絕對，spring boot也是可以引用xml配置的)

引入依賴：

   <dependency>
      <artifactId>ehcache-core</artifactId>
      <groupId>net.sf.ehcache</groupId>
      <version>2.5.0</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-ehcache</artifactId>
      <version>1.2.2</version>
    </dependency>

    <dependency>
      　　<groupId>org.slf4j</groupId>
      　　<artifactId>slf4j-api</artifactId>
      　　<version>1.7.25</version>
    </dependency>    
   <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-core</artifactId>
      <version>1.2.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-web</artifactId>
      <version>1.2.3</version>
    </dependency>
    <dependency>
      <groupId>org.apache.shiro</groupId>
      <artifactId>shiro-spring</artifactId>
      <version>1.2.3</version>
    </dependency>
 

如果你出現錯誤 找不到slf4j，引入依賴

<dependency>
  　　<groupId>org.slf4j</groupId>
  　　<artifactId>slf4j-log4j12</artifactId>
  　　<version>1.7.25</version>
</dependency>

傳統xml配置如下：

轉換成bean 新建類ShiroConfig

@Configuration
public class ShiroConfig {

//自定義密碼
  @Bean
  public RetryLimitCredentialsMatcher getRetryLimitCredentialsMatcher(){
    RetryLimitCredentialsMatcher rm=new RetryLimitCredentialsMatcher(getCacheManager(),"5");
    rm.setHashAlgorithmName("md5");
    rm.setHashIterations(4);
    return rm;

  }
 

  @Bean
  public LoginRealm getLoginRealm(){
    LoginRealm realm= new LoginRealm();
    realm.setCredentialsMatcher(getRetryLimitCredentialsMatcher());
    return realm;
  }

  @Bean
  public EhCacheManager getCacheManager(){
    EhCacheManager ehCacheManager=new EhCacheManager();
    ehCacheManager.setCacheManagerConfigFile("classpath:ehcache/ehcache.xml");
    return ehCacheManager;
  }

  @Bean
  public LifecycleBeanPostProcessor getLifecycleBeanPostProcessor() {
    return new LifecycleBeanPostProcessor();
  }
    //會話
  @Bean(name="securityManager")
  public DefaultWebSecurityManager getDefaultWebSecurityManager(){
    DefaultWebSecurityManager dwm=new DefaultWebSecurityManager();
    dwm.setRealm(getLoginRealm());
    dwm.setCacheManager(getCacheManager());
    return dwm;
  }

  @Bean
  public PermissionFilter getPermissionFilter(){
    PermissionFilter pf=new PermissionFilter();
    return pf;
  }

  @Bean
  public VerfityCodeFilter getVerfityCodeFilter(){
    VerfityCodeFilter vf= new VerfityCodeFilter();
    vf.setFailureKeyAttribute("shiroLoginFailure");
    vf.setJcaptchaParam("code");
    vf.setVerfitiCode(true);
    return vf;
  }

  @Bean(name = "shiroFilter")
  public ShiroFilterFactoryBean getShiroFilterFactoryBean(){
    ShiroFilterFactoryBean sfb = new ShiroFilterFactoryBean();
    sfb.setSecurityManager(getDefaultWebSecurityManager());
    sfb.setLoginUrl("/login");
    sfb.setUnauthorizedUrl("/goLogin");
    Map<String, Filter> filters=new HashMap<>();
    filters.put("per",getPermissionFilter());
    filters.put("verCode",getVerfityCodeFilter());
    sfb.setFilters(filters);

    Map<String, String> filterMap = new LinkedHashMap<>();
    filterMap.put("/login","verCode,anon");
    //filterMap.put("/login","anon");
    filterMap.put("/getCode","anon");
    filterMap.put("/logout","logout");
    filterMap.put("/plugin/**","anon");
    filterMap.put("/user/**","per");
    filterMap.put("/**","authc");
    sfb.setFilterChainDefinitionMap(filterMap);
    return sfb;
  }

  @Bean
  public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator() {
    DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
    advisorAutoProxyCreator.setProxyTargetClass(true);
    return advisorAutoProxyCreator;
  }

  @Bean
  public AuthorizationAttributeSourceAdvisor getAuthorizationAttributeSourceAdvisor(){
    AuthorizationAttributeSourceAdvisor as=new AuthorizationAttributeSourceAdvisor();
    as.setSecurityManager(getDefaultWebSecurityManager());
    return as;
  }

  @Bean
  public FilterRegistrationBean delegatingFilterProxy(){
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
    DelegatingFilterProxy proxy = new DelegatingFilterProxy();
    proxy.setTargetFilterLifecycle(true);
    proxy.setTargetBeanName("shiroFilter");
    filterRegistrationBean.setFilter(proxy);
    return filterRegistrationBean;
  }

其中有個別類是自定義的攔截器和 realm，此時spring 即能注入shiro 也就是 spring boot整合上了 shiro

如果你因為其他配置引起一些失敗，可以參考開源專案 lenos快速開發腳手架 spring boot版本，其中有對shiro的整合，可以用來學習
