一、Shiro授权

授角色：用户具备哪些角色

SELECT roleid from t_shiro_user u,t_shiro_user_role ur
where u.userid = ur.userid and u.username = 'zdm'

授权限：用户具备哪些权限

SELECT rp.perid from t_shiro_user u, t_shiro_user_role ur,t_shiro_role_permission rp
where u.userid = ur.userid and ur.roleid= rp.roleid and u.username = 'ww

步骤：

1、Mapper层、service层

UserMapper.xml:

<select id="selectRoleIdsByUserName" resultType="java.lang.String" parameterType="java.lang.String" >
   SELECT roleid from t_shiro_user u,t_shiro_user_role ur
where u.userid = ur.userid and u.username = #{userName}
  </select>
 
  <select id="selectPerIdsByUserName" resultType="java.lang.String" parameterType="java.lang.String" >
  SELECT rp.perid from t_shiro_user u, t_shiro_user_role ur,t_shiro_role_permission rp
where u.userid = ur.userid and ur.roleid= rp.roleid and u.username = #{userName}
  </select>

 UserMapper :

package com.ycx.mapper;
 
import com.ycx.model.User;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
 
import java.util.Set;
 
@Repository
public interface UserMapper {
    int deleteByPrimaryKey(Integer userid);
 
    int insert(User record);
 
    int insertSelective(User record);
 
    User selectByPrimaryKey(Integer userid);
 
    //通过账户名查询账户信息
    User queryUserByUserName (@Param("userName") String userName);
 
    //通过账户名查询对应的角色
    Set selectRoleIdsByUserName (@Param("userName") String userName);
 
    //通过账户名查询对应的权限
    Set  selectPerIdsByUserName (@Param("userName") String userName);
 
    int updateByPrimaryKeySelective(User record);
 
    int updateByPrimaryKey(User record);
}

UserBiz : 

package com.ycx.ssm.biz;
 
import com.ycx.model.User;
 
import java.util.Set;
 
public interface UserBiz {
    int deleteByPrimaryKey(Integer userid);
 
    int insert(User record);
 
    int insertSelective(User record);
 
    User selectByPrimaryKey(Integer userid);
 
    User queryUserByUserName(String userName);
 
    int updateByPrimaryKeySelective(User record);
 
    int updateByPrimaryKey(User record);
 
    //通过账户名查询对应的角色
    Set selectRoleIdsByUserName (String userName);
 
    //通过账户名查询对应的权限
    Set  selectPerIdsByUserName (String userName);
 
}

UserBizImpl :

package com.ycx.ssm.biz.impl;
 
import com.ycx.mapper.UserMapper;
import com.ycx.model.User;
import com.ycx.ssm.biz.UserBiz;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
import java.util.Set;
 
/**

@Service("userBiz")
public class UserBizImpl implements UserBiz {
    @Autowired
    private UserMapper userMapper;
    @Override
    public int deleteByPrimaryKey(Integer userid) {
        return userMapper.deleteByPrimaryKey(userid);
    }
 
    @Override
    public int insert(User record) {
        return userMapper.insert(record);
    }
 
    @Override
    public int insertSelective(User record) {
        return userMapper.insertSelective(record);
    }
 
    @Override
    public User selectByPrimaryKey(Integer userid) {
        return userMapper.selectByPrimaryKey(userid);
    }
 
    @Override
    public User queryUserByUserName(String userName) {
        return userMapper.queryUserByUserName(userName);
    }
 
    @Override
    public int updateByPrimaryKeySelective(User record) {
        return userMapper.updateByPrimaryKeySelective(record);
    }
 
    @Override
    public int updateByPrimaryKey(User record) {
        return userMapper.updateByPrimaryKeySelective(record);
    }
 
    @Override
    public Set<String> selectRoleIdsByUserName(String userName) {
        return userMapper.selectRoleIdsByUserName(userName);
    }
 
    @Override
    public Set<String> selectPerIdsByUserName(String userName) {
        return userMapper.selectPerIdsByUserName(userName);
 
    }
}

MyRealm :

package com.ycx.shiro;
 
import com.ycx.model.User;
import com.ycx.ssm.biz.UserBiz;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
 
import java.util.Set;
 
/**
 * @author 杨总
 * @create 2022-08-25 19:38
 */
public class MyRealm extends AuthorizingRealm {
    public UserBiz userBiz;
 
    public UserBiz getUserBiz() {
        return userBiz;
    }
 
    public void setUserBiz(UserBiz userBiz) {
        this.userBiz = userBiz;
    }
 
    /**
     * 授权
     * @param principals
     * @return
     * shiro-web.ini
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String userName = principals.getPrimaryPrincipal().toString();//获取账户名
        Set<String> roleIds = userBiz.selectRoleIdsByUserName(userName);
        Set<String> perIds = userBiz.selectPerIdsByUserName(userName);
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//       将当前登录的权限交给shiro的授权器
        info.setStringPermissions(perIds);
//        将当前登录的角色交给shiro的授权器
        info.setRoles(roleIds);
        return info;
    }
 
    /**
     * 认证
     * @param token
     * @return
     * @throws AuthenticationException
     * shiro.ini
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        String userName = token.getPrincipal().toString();
        User user = null;
        try {
            user = userBiz.queryUserByUserName(userName);
        }catch (Exception e){
            e.printStackTrace();
        }
        AuthenticationInfo info=new SimpleAuthenticationInfo(
                user.getUsername(),
                user.getPassword(),
                ByteSource.Util.bytes(user.getSalt()),
                this.getName()//realm的名字
        );
        return info;
    }
}

2、shiro 的 授权方式

        注意：角色与权限的结果要与spring-shiro.xml的配置保持一致

                角色：1,4

                权限：1,2

3、测试

 

 

 

 

 

 

 

二、shiro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
 

 

1）将对应注解添加到指定需要权限控制的方法上

身份认证：requireUser

角色认证：requireRole

权限认证: requirePermission

（2）在SpringMVC.xml中添加拦截相关配置

controller层

ShiroController :

package com.ycx.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;
 
/**
 * @author 杨总
 * @create 2022-08-26 20:22
 */
@RequestMapping("/shiro")
@Controller
public class ShiroController {
//   RequiresUser代表 当前方法只有登录后才能够访问
//    RequiresUser等价于spring-shiro.xml中的/user/updatePwd.jsp=authc配置
    @RequiresUser
    @RequestMapping("/passUser")
    public String passUser(){
        System.out.println("身份认证通过！");
        return "admin/addUser";
    }
//RequiresRoles 代表当前方法只有具备指定的角色才能访问
//    RequiresRoles等价于spring-shiro.xml中的/admin/*.jsp=roles[4]配置
    @RequiresRoles(value = {"1","4"},logical = Logical.AND)
    @RequestMapping("/passRole")
    public String passRole(){
        System.out.println("角色认证通过！");
        return "admin/addUser";
    }
 
    //RequiresRoles 代表当前方法只有具备指定的权限才能访问
//    RequiresRoles等价于spring-shiro.xml中的/user/teacher.jsp=perms[2]配置
    @RequiresPermissions(value = {"2"},logical = Logical.AND)
    @RequestMapping("/passPermission")
    public String passPermission(){
        System.out.println("权限认证通过！");
        return "admin/addUser";
    }
}

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>

 

再输入地址栏 http://localhost:8080/shiro/passUser：

进入成功

再输入地址栏 http://localhost:8080/shiro/passRole : 

 

再切换ls登录：

 

 登录进去之后：

 

 

再输入地址栏 http://localhost:8080/shiro/passRole ：

 

 错误又不一样了.

如果换zdm登录：

进入之后再输入地址栏 http://localhost:8080/shiro/passRole ：

 

 

可进行访问。

退出再次登录zs，然后地址栏输入http://localhost:8080/shiro/passPermission：

显示没有权限2.

而登录ls，再次输入：

 

 则有用户新增。

如果把AND改为OR：

 再次登录zs时，/shiro/passRole

 

  之前是不可访问的，现在可访问了。
