shiro授权、注解式开发

1、shiro授权角色、权限

2、Shiro的注解式开发

授权

ShiroUserMapper.xml

<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>

Service层

package com.zhuling.service;

import com.zhuling.model.ShiroUser;

import java.util.Set;

public interface ShiroUserService {
    public Set<String> getRolesByUserId(Integer userId);

    public Set<String> getPersByUserId(Integer userId);

    public ShiroUser queryByName(String userName);
}

ShiroUserServiceImpl

package com.zhuling.service.impl;

import com.zhuling.mapper.ShiroUserMapper;
import com.zhuling.model.ShiroUser;
import com.zhuling.service.ShiroUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Set;

@Service("shiroUserService")
public class ShiroUserServiceImpl implements ShiroUserService {
    @Autowired
    private ShiroUserMapper shiroUserMapper;

    @Override
    public ShiroUser queryByName(String uname) {
        return shiroUserMapper.queryByName(uname);
    }

    @Override
    public int insert(ShiroUser record) {
        return shiroUserMapper.insert(record);
    }

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

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

重写自定义realm中的授权方法

/**
     * 授权的方法
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String uname=principalCollection.getPrimaryPrincipal().toString();
        ShiroUser shiroUser = this.shiroUserService.queryByName(uname);
        Set<String> perids= this.shiroUserService.getPersByUserId(shiroUser.getUserid());
        Set<String> roleIds= this.shiroUserService.getRolesByUserId(shiroUser.getUserid());
        SimpleAuthorizationInfo info=new SimpleAuthorizationInfo();
        info.setRoles(roleIds);
        info.setStringPermissions(perids);
        return info;
    }

注解式开发

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

注解的使用

Controller层

@RequiresUser
    @ResponseBody
    @RequestMapping("/passUser")
    public  String passUser(HttpServletRequest req) {
        return "，身份认证成功，能够访问！！！";
    }

    @RequiresRoles(value = {"2"},logical = Logical.AND)
    @ResponseBody
    @RequestMapping("/passRole")
    public  String passRole(HttpServletRequest req) {
        return "，角色认证成功，能够访问！！！";
    }

    @RequiresPermissions(value = {"user:update","user:load"},logical = Logical.AND)
    @ResponseBody
    @RequestMapping("/passPer")
    public  String passPer(HttpServletRequest req) {
        return "，权限认证成功，能够访问！！！";
    }

springmvc-servlet.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>

Jsp

<ul>
    shiro注解
    <li>
        <a href="${pageContext.request.contextPath}/passUser">用户认证</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passRole">角色</a>
    </li>
    <li>
        <a href="${pageContext.request.contextPath}/passPer">权限认证</a>
    </li>
</ul>
