一、shiro授权

1、在ShiroUserMapper.xml中新增内容

2、在ShiroUserMapper中新增内容

3、Service层

①、ShiroUserService

②、ShiroUserServiceImpl

一、shiro授权

1、在ShiroUserMapper.xml中新增内容

<select id="getRolesByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
  select r.roleid from t_shiro_user u,t_shiro_user_role ur,t_shiro_role r
    where u.userid = ur.userid and ur.roleid = r.roleid
    and u.userid = #{userid}
</select>
<select id="getPersByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
  select p.permission from t_shiro_user u,t_shiro_user_role ur,t_shiro_role_permission rp,t_shiro_permission p
  where u.userid = ur.userid and ur.roleid = rp.roleid and rp.perid = p.perid
  and u.userid = #{userid}
</select>

2、在ShiroUserMapper中新增内容

public Set<String> getRolesByUserId(@Param("userid")Integer userid);

public Set<String> getPersByUserId(@Param("userid")Integer userid);

3、Service层

①、ShiroUserService

public Set<String> getRolesByUserId(Integer userId);
public Set<String> getPersByUserId(Integer userId);

②、ShiroUserServiceImpl

 @Override
    public Set<String> getRolesByUserId(Integer userid) {
        return shiroUserMapper.getRolesByUserId(userid);
    }

    @Override
    public Set<String> getPersByUserId(Integer userid) {
        return shiroUserMapper.getPersByUserId(userid);
    }

4、重写自定义Myrealm中的授权方法

 //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        /*
         * 授权
         *   1、给用户授予角色
         *   2、给用户授予权限
         * 授予权限做法：
         *   1、拿到账号
         *   2、通过用户账号查询对应的能看到的那些菜单
         *   3、将这些权限交给shiro管理
         * 授予角色做法：
         *   1、拿到账号
         *   2、通过用户账号查询对应的能看到的那些角色
         *   3、将这些权限交给shiro管理
         * Mapper.xml
         * */
        System.out.println("用户授权...");
        String username = principals.getPrimaryPrincipal().toString();
        ShiroUser user = shiroUserService.queryByName(username);
        Set<String> roles = shiroUserService.getRolesByUserId(user.getUserid());
        Set<String> pers = shiroUserService.getPersByUserId(user.getUserid());
//        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//        info.addRoles(roles);
//        info.addStringPermissions(pers);

        SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
        info.setRoles(roles);
        info.setStringPermissions(pers);
        return info;
    }

5、运行结果

二、Shiro的注解式开

1、常用注解介绍

  @RequiresAuthenthentication:表示当前Subject已经通过login进行身份验证;即 Subject.isAuthenticated()返回 true

  @RequiresUser:表示当前Subject已经身份验证或者通过记住我登录的

  @RequiresGuest:表示当前Subject没有身份验证或者通过记住我登录过，即是游客身份

  @RequiresRoles(value = {"admin","user"},logical = Logical.AND):表示当前Subject需要角色admin和user

  @RequiresPermissions(value = {"user:delete","user:b"},logical = Logical.OR):表示当前Subject需要权限user:delete或者user:b

2、注解的使用

①、Controller层

AnnotationController.java

package com.ysq.controller;

import org.apache.shiro.authz.annotation.Logical;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.apache.shiro.authz.annotation.RequiresUser;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
@Controller
public class AnnotationController {
    @RequiresUser
    @RequestMapping("/passUser")
    public String passUser(HttpServletRequest request){
        return "admin/addUser";
    }

    @RequiresRoles(value = {"1","4"},logical = Logical.AND)
    @RequestMapping("/passRole")
    public String passRole(HttpServletRequest request){
        return "admin/listUser";
    }

    @RequiresPermissions(value = {"user:update","user:view"},logical = Logical.OR)
    @RequestMapping("/passPer")
    public String passPer(HttpServletRequest request){
        return "admin/resetPwd";
    }

    @RequestMapping("/unauthorized")
    public String unauthorized(){
        return "unauthorized";
    }

}

②、spring-mvc.xml

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
      depends-on="lifecycleBeanPostProcessor">
    <property name="proxyTargetClass" value="true"></property>
</bean>
<bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
    <property name="securityManager" ref="securityManager"/>
</bean>

<bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <property name="exceptionMappings">
        <props>
            <prop key="org.apache.shiro.authz.UnauthorizedException">
                unauthorized
            </prop>
        </props>
    </property>
    <property name="defaultErrorView" value="unauthorized"/>
</bean>

3、hello.jsp
