Spring Boot 整合 Shiro 实现登录认证与权限控制

用户角色权限数据库设计

数据库这里以 MySQL 为例

创建数据库

所需表如下:

  • user:用户表
  • role:角色表
  • perm:权限菜单表
  • user_role:用户与角色关联的中间表
  • role_prem:角色与权限菜单关联的中间表

执行数据库脚本

DROP TABLE IF EXISTS `perm`;
CREATE TABLE `perm`  (
  `perm_id` int(32) NOT NULL COMMENT '权限主键',

数据库设计完成以后,将相对应的实体类和 mapper 文件加入到项目当中

业务代码

这里我们需要定义一个业务接口查询用户的相关信息(包括用户关联的角色与权限)

这里不阐述具体的 SQL 语句

UserService

public interface UserService {
    
   /**
     * 根据用户名查询用户信息(包含角色及权限信息)
     * @param username 用户名
     * @return User
     */
    User selectByUsername(String username);
}

UserServiceImpl

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public User selectByUsername(String username) {

        return userMapper.selectByUsername(username);
    }
}

引入依赖

pox.xml
中添加 org.apache.shiro:shiro-spring
com.github.theborakompanioni:thymeleaf-extras-shiro
依赖

<properties>
    <thymeleaf-extras-shiro.version>2.0.0</thymeleaf-extras-shiro.version>
    <shiro.version>1.4.0</shiro.version>
</properties>

<dependencies>
    <!-- Shiro核心依赖 -->
    <dependency>
        <groupId>org.apache.shiro</groupId>
        <artifactId>shiro-spring</artifactId>
        <version>${shiro.version}</version>
    </dependency>

    <!-- Thymeleaf对Shiro的支持 -->
    <dependency>
      <groupId>com.github.theborakompanioni</groupId>
      <artifactId>thymeleaf-extras-shiro</artifactId>
      <version>${thymeleaf-extras-shiro.version}</version>
    </dependency>
</dependencies>

自定义认证和授权

创建 MyRealm
类实现认证与授权

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
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.subject.Subject;
import org.apache.shiro.util.ByteSource;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.Collection;
import java.util.HashSet;
import java.util.List;

/**
 * 自定义Realm,实现授权与认证
 */
public class MyRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    /**
     * 用户认证
     **/
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        User user = userService.selectByUsername(token.getUsername());
        if (user == null) {
            throw new UnknownAccountException();
        }
        return new SimpleAuthenticationInfo(user, user.getPassword(), getName());
    }

    /**
     * 用户授权
     **/
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        Subject subject = SecurityUtils.getSubject();
        User user = (User) subject.getPrincipal();
        if (user != null) {
            SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
            List<String> roles = new LinkedList<>();
            List<String> perms = new LinkedList<>();
            for (Role role : user.getRoleList()) {
                roles.add(role.getRoleName());
            }
            for (Perm perm : user.getPermList()) {
                perms.add(perm.getPermUrl());
            }
            simpleAuthorizationInfo.addRoles(roles);
            simpleAuthorizationInfo.addStringPermissions(perms);
            return simpleAuthorizationInfo;
        }
        return null;
    }
}

Java 中使用 Shiro 权限注解

除了在 ShiroConfig 配置类中自定义权限过滤规则,还可以使用 Shiro 提供的注解实现权限过滤,在 Controller 中的每个请求方法上可以添加以下注解实现权限控制

@RequiresAuthentication: 只有认证通过的用户才能访问

@RequiresRoles(value = {“root”}, logical = Logical.OR)

  • value
    :指定拥有 root 角色才能访问,角色可以是多个,以逗号隔开
  • logical
    :该属性有两个值,Logical.OR(只要拥有其中一个角色就能访问),Logical.AND(需要拥有指定的全部角色才能访问,否则会抛出权限不足异常)

@RequiresPermissions(value = {“/user/delete”}, logical = Logical.OR) :

  • value:
    指定拥有 /user/delete 权限才能访问,权限可以是多个,以逗号隔开
  • logical:
    有两个值,Logical.OR(只要拥有其中一个权限就访问),Logical.AND(需要拥有指定的全部权限才能访问,否则会抛出权限不足异常)

Thymeleaf 模板中使用 Shiro 权限标签

修改 thymeleaf 模板的 html 标签,加入
xmlns:shiro=” http://www.pollix.at/thymelea…

命名空间

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:th="http://www.thymeleaf.org"
      xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">

常用的 Shiro 标签有以下:

  • <shiro:hasRole=”root”>:需要拥有root角色
  • <shiro:hasAnyRoles=”root,guest”>:需要拥有root和guest中的任意一个角色
  • <shiro:hasAllRoles =”root,guest”>:需要同时拥有root和guest角色
  • <shiro:hasPerm>:原理同上
  • <shiro:hasAnyPerms> :原理同上
  • <shiro:hasAllPerms> :原理同上

登录

  • 启动项目
  • 访问 http://localhost:8080
  • 用户名:root
  • 登录密码:123456
