spring boot集成shiro详细教程(小结)

我们开发时候有时候要把传统spring shiro转成spring boot项目，或者直接集成，name我们要搞清楚一个知识，就是 xml配置和spring bean代码配置的关系，这一点很重要，因为spring boot是没有xml配置文件的(也不绝对，spring boot也是可以引用xml配置的)

引入依赖：

  <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>

如果你出现错误 找不到slf4j，引入依赖

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

传统xml配置如下：

  <property name="securityManager" ref="securityManager" />
 </bean>

 <bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
</beans>

转换成bean 新建类ShiroConfig

@Configuration
public class ShiroConfig {
 @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();
 }

 @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;
 }

其中有个别类是自定义的拦截器和 realm，此时spring 即能注入shiro 也就是 spring boot集成上了 shiro

如果你因为其他配置引起一些失败，可以参考开源项目 lenos快速开发脚手架 spring boot版本，其中有对shiro的集成，可以用来学习
