shiro使用注解（@RequiresPermissions等）不无效及异常处理

1、注解不生效

在shiro配置类中加上如下代码：

　　/**
     * Shiro生命周期处理器
     */
    @Bean(name = "lifecycleBeanPostProcessor")
    public static LifecycleBeanPostProcessor getLifecycleBeanPostProcessor() {
        return new LifecycleBeanPostProcessor();
    }

    /**
     * 开启Shiro的注解(如@RequiresRoles,@RequiresPermissions),需借助SpringAOP扫描使用Shiro注解的类,并在必要时进行安全逻辑验证
     */
    @Bean
    @DependsOn("lifecycleBeanPostProcessor")
    public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
        DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
        creator.setProxyTargetClass(true);
        return creator;
    }

　　/**
 　　* 开启shiro aop注解支持.
 　　* 使用代理方式;所以需要开启代码支持;
 　　*/
　　@Bean
　　public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
   　　 AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
    　　authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
   　　 return authorizationAttributeSourceAdvisor;
　　}

2、异常处理

过滤器必须要是AuthorizationFilter过滤器才能生效，即只有perms，roles，ssl，rest，port才是属于AuthorizationFilter，而anon，authcBasic，auchc，user是AuthenticationFilter，所以unauthorizedUrl设置后页面不跳转。此处使用springmvc同意异常处理来解决：

package com.example.springbootshiro.controller;

import com.example.springbootshiro.constants.CommonConstants;
import com.example.springbootshiro.domain.vo.ResponseVO;
import com.example.springbootshiro.enums.ResponseStatusEnum;
import com.example.springbootshiro.utils.ResultUtil;
import org.apache.shiro.authz.AuthorizationException;
import org.apache.shiro.authz.UnauthorizedException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

import java.lang.reflect.UndeclaredThrowableException;

/**
 * 统一异常处理类<br>
 * 捕获程序所有异常，针对不同异常，采取不同的处理方式
 *
 */
@ControllerAdvice
public class ExceptionHandleController {
    private static final Logger LOGGER = LoggerFactory.getLogger(ExceptionHandleController.class);

//    @ResponseBody
    @ExceptionHandler(UnauthorizedException.class)
    public String handleShiroException(Exception ex) {
        return "redirect:/error/403";
    }

//    @ResponseBody
    @ExceptionHandler(AuthorizationException.class)
    public String AuthorizationException(Exception ex) {
        return "redirect:/error/401";
    }

}

具体处理逻辑自己控制
