SpringBoot 集成 SpringSecurity + MySQL + JWT 附源码，废话不多直接盘

Posted on by hackdl

SpringBoot 集成 SpringSecurity + MySQL + JWT 无太多理论，直接盘
一般用于Web管理系统
可以先看 SpringBoot SpringSecurity 基于内存的使用介绍
本文介绍如何整合 SpringSecurity + MySQL + JWT

数据结构

数据库脚本：https://gitee.com/VipSoft/VipBoot/blob/develop/vipsoft-security/sql/Security.sql

常规权限管理数据结构设计，三张常规表：用户、角色、菜单，通过用户和角色的关系，角色和菜单（权限）的关系，实现用户和菜单（按钮）的访问控制权

用户登录

  1. SecurityConfig 中添加登录接口匿名访问配置

    .antMatchers("/auth/login", "/captchaImage").anonymous()
    BCryptPasswordEncoder 密码加密方式

  2. POST 登录接口 /auth/login

    调用 AuthorizationController.login 用户登录接口
    做入参、图形验证码等验证。

  3. 实现 UserDetailsService 接口

    根据用户名，去数据库获取用户信息、权限获取等

  4. 密码验证

    AuthorizationService.login
    调用 authenticationManager.authenticate(authenticationToken) 看密码是否正确
    可以在此集合 Redis 做失败次数逻辑处理

  5. 通过JWT 生成 Token

    调用 jwtUtil.generateToken(userId) 生成Token令牌
    将 用户信息放入 Redis
    剔除其它已登录的用户（如果需要）

  6. 返回Map对象给前端

接口权限认证

  1. 获取request.getHeader中的token信息

    AuthenticationTokenFilter.doFilterInternal
    解析 Token 中的用户ID 去 Redis 缓存中获取用户信息
    将信息赋到 SecurityContextHolder.getContext().setAuthentication(authenticationToken) 中，供权限验证获取用户信息使用, SecurityContextHolder使用了ThreadLocal机制来保存每个使用者的安全上下文

  2. 接口权限配置

    UserController 类的方法上，加了 @PreAuthorize("@ps.hasAnyPermi('system:user:list')") 用来做权限控制

  3. 访问权限控制

    PermissionService.hasAnyPermi 判断，用户所拥有的权限，是否包含 @PreAuthorize("@ps.hasAnyPermi('system:user:list')") 中配置的权限，包含则有权访问

AuthenticationTokenFilter
“`java
@Component
public class AuthenticationTokenFilter extends OncePerRequestFilter {
@Autowired
private JwtUtil jwtUtil;

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws ServletException, IOException {
    LoginUser loginUser = jwtUtil.getLoginUser(request);
    if (loginUser != null && SecurityUtils.getAuthentication() == null) {
        jwtUtil.verifyToken(loginUser);
        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(loginUser, null, loginUser.getAuthorities());
        authenticationToken.setDetails(new WebAuthenticationDetailsSource().buildDetails(request));
        //SecurityContextHolder使用了ThreadLocal机制来保存每个使用者的安全上下文，确保PermissionService判断权限时可以获得当前LoginUser信息
        SecurityUtils.setAuthentication(authenticationToken);
    }
    chain.doFilter(request, response);
}

}


定义权限验证类 `PermissionService`
```java
package com.vipsoft.web.security;

import cn.hutool.core.util.StrUtil;
import com.vipsoft.web.utils.SecurityUtils;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;

import java.util.Arrays;
import java.util.Set;

/**
 * 自定义权限实现
 */
@Service("ps")
public class PermissionService {
    /**
     * 所有权限标识
     */
    private static final String ALL_PERMISSION = "*:*:*";

    /**
     * 管理员角色权限标识
     */
    private static final String SUPER_ADMIN = "admin";

    private static final String ROLE_DELIMETER = ",";

    private static final String PERMISSION_DELIMETER = ",";


    /**
     * 对用户请求的接口进行验证，看接口所需要的权限，当前用户是否包括
     *
     * @param permissions 以 PERMISSION_NAMES_DELIMETER 为分隔符的权限列表，如：system:user:add,system:user:edit
     * @return 用户是否具有以下任意一个权限
     */
    public boolean hasAnyPermi(String permissions) {
        if (StrUtil.isEmpty(permissions)) {
            return false;
        }
        LoginUser loginUser = SecurityUtils.getCurrentUser(); //去SecurityContextHolder.getContext()中获取登录用户信息
        if (loginUser == null || CollectionUtils.isEmpty(loginUser.getPermissions())) {
            return false;
        }
        Set authorities = loginUser.getPermissions();
        String[] perms = permissions.split(PERMISSION_DELIMETER);
        boolean hasPerms = Arrays.stream(perms).anyMatch(authorities::contains);
        //是Admin权限 或者 拥有接口所需权限时
        return permissions.contains(ALL_PERMISSION) || hasPerms;
    }
}
