shiro authorization, annotation style development

 What's new in the 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 Layer

 

com.jt.service package; 


import com.jt.model.ShiroUser; 
import org.apache.ibatis.annotations.Param; 

import java.util.Set; 

public  interface ShiroUserService { 

    ShiroUser queryByName (gparam ( " uname " ) String uname); 

    int insert (ShiroUser record); 

    Set <String> getRolesByUserId (gparam ( " userid " ) Integer userid); 

    Set <String> getPersByUserId (gparam ( " userid " ) Integer userid); 

}

 

 

 

ShiroUserServiceImpl

package com.jt.service.impl;

import com.jt.mapper.ShiroUserMapper;
import com.jt.model.ShiroUser;
import com.jt.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);
    }
}

Rewrite the custom realm authorization methods

 

 /**
     * 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;
    }

 

Notes-style development

Common notes Introduction

 

  @RequiresAuthenthentication: Indicates the current Subject has passed login for authentication ; namely Subject.isAuthenticated () returns true

  @RequiresUser: Indicates the current Subject has been authenticated by or login Remember me

  @RequiresGuest: Indicates the current Subject no authentication or by Remember me logged in before, that is, as a visitor

  @RequiresRoles (value = { "admin" , "user"}, logical = Logical.AND): Indicates the current Subject required roles admin and user

  @RequiresPermissions (value = { "user: delete", "user: b"}, logical = Logical.OR): Indicates the current Subject needs permission user: delete or user: b

 

Use annotations

 

 

 

Controller layer

 

 

@RequiresUser 
    @ResponseBody 
    @RequestMapping ( " / passUser " )
     public   String passUser (the HttpServletRequest REQ) {
         return  " , a successful authentication, access to !!! " ; 
    } 

    @RequiresRoles (value = { " 2 " }, = Logical the Logical. the AND) 
    @ResponseBody 
    @ RequestMapping ( " / passRole " )
     public   String passRole (the HttpServletRequest REQ) {
         return  " , the role of authentication is successful, be able to visit !!! " ; 
    }

    @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！！！";
    }

Jsp test code

 

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