1，概述

接上一个知识点，上一个项目里面我们实现的是在jsp页面如何判断用户有没有某个角色和权限，那么在前后端分离的情况下【没有jsp】如何去实现呢，我们接着上一个项目开发

2，复制项目

3，修改appliaction-shiro.xml

4，修改UserController

@RestController
    @RequestMapping("user")
    public class UserController {
    
    	@RequestMapping("query")
    	@RequiresPermissions("user:query")
    	public Map<String,Object> query(){
    		Map<String,Object> map=new HashMap<>();
    		map.put("msg", "query");
    		return map;
    	}
    	@RequestMapping("add")
    	@RequiresPermissions("user:add")
    	public Map<String,Object> add(){
    		Map<String,Object> map=new HashMap<>();
    		map.put("msg", "add");
    		return map;
    	}
    	@RequiresPermissions("user:update")
    	@RequestMapping("update")
    	public Map<String,Object> update(){
    		Map<String,Object> map=new HashMap<>();
    		map.put("msg", "update");
    		return map;
    	}
    	@RequestMapping("delete")
    	@RequiresPermissions("user:delete")
    	public Map<String,Object> delete(){
    		Map<String,Object> map=new HashMap<>();
    		map.put("msg", "delete");
    		return map;
    	}
    	@RequestMapping("export")
    	@RequiresPermissions("user:export")
    	public Map<String,Object> export(){
    		Map<String,Object> map=new HashMap<>();
    		map.put("msg", "export");
    		return map;
    	}
    	
    }

5，创建CommonController

@RestController
    @RequestMapping("common")
    public class CommonController {
    
    	/**
    	 * 未登陆
    	 */
    	@RequestMapping("unLogin")
    	public Object unLogin() {
    		Map<String,Object> map=new HashMap<>();
    		map.put("code", -1);
    		map.put("msg", "未登陆");
    		return map;
    	}	
    }

6，创建GlobalExceptionHanderAdvise全局异常监控

/**
     * 全局的异常监控
     * @author LJH
     *
     */
    
    //@ControllerAdvice  这个注解是监视Controller里面是否有异常发生，如果发生就跳转页面
    @RestControllerAdvice 
    public class GlobalExceptionHanderAdvise {
    	
    	/**
    	 * 未授权
    	 */
    	@ExceptionHandler(value= {UnauthorizedException.class})
    	public Object unauthorized() {
    		Map<String,Object> map=new HashMap<>();
    		map.put("code", -1);
    		map.put("msg", "未授权，请联系管理员");
    		return map;
    	}
    	
    }

6，修改springmvc.xml开启shiro注解

<context:component-scan base-package="com.sxt.aspect"></context:component-scan>
    	
    	<bean id="lifecycleBeanPostProcessor" class="org.apache.shiro.spring.LifecycleBeanPostProcessor" />
    	<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator" depends-on="lifecycleBeanPostProcessor" />
    	<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
    		<property name="securityManager" ref="securityManager" />
    	</bean>
