SpringBoot 整合SpringSecurity示例实现前后分离权限注解+JWT登录认证

一.说明

SpringSecurity是一个用于Java 企业级应用程序的安全框架,主要包含用户认证和用户授权两个方面.相比较Shiro而言,Security功能更加的强大,它可以很容易地扩展以满足更多安全控制方面的需求,但也相对它的学习成本会更高,两种框架各有利弊.实际开发中还是要根据业务和项目的需求来决定使用哪一种.

JWT是在Web应用中安全传递信息的规范,从本质上来说是Token的演变,是一种生成加密用户身份信息的Token,特别适用于分布式单点登陆的场景,无需在服务端保存用户的认证信息,而是直接对Token进行校验获取用户信息,使单点登录更为简单灵活.

二.项目环境

• SpringBoot版本:2.1.6

• SpringSecurity版本: 5.1.5

• MyBatis-Plus版本: 3.1.0

• JDK版本:1.8

• 数据表(SQL文件在项目中):数据库中测试号的密码进行了加密,密码皆为123456

                log.info("Token无效");
            }
        }
        filterChain.doFilter(request, response);
        return;
    }
}

六.权限注解和hasPermission权限扩展

Security允许我们在定义URL方法访问所应有的注解权限时使用SpringEL表达式,在定义所需的访问权限时如果对应的表达式返回结果为true则表示拥有对应的权限,反之则没有权限,会进入到我们配置的UserAuthAccessDeniedHandler(暂无权限处理类)中进行处理.这里举一些例子,代码中注释有对应的描述.

    /**
     * 管理端信息
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回数据MAP
     */
    @PreAuthorize("hasRole('ADMIN')")
    @RequestMapping(value = "/info",method = RequestMethod.GET)
    public Map<String,Object> userLogin(){
        Map<String,Object> result = new HashMap<>();
        SelfUserEntity userDetails = SecurityUtil.getUserInfo();
        result.put("title","管理端信息");
        result.put("data",userDetails);
        return ResultUtil.resultSuccess(result);
    }
    /**
     * 拥有ADMIN或者USER角色可以访问
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回数据MAP
     */
    @PreAuthorize("hasAnyRole('ADMIN','USER')")
    @RequestMapping(value = "/list",method = RequestMethod.GET)
    public Map<String,Object> list(){
        Map<String,Object> result = new HashMap<>();
        List<SysUserEntity> sysUserEntityList = sysUserService.list();
        result.put("title","拥有用户或者管理员角色都可以查看");
        result.put("data",sysUserEntityList);
        return ResultUtil.resultSuccess(result);
    }
    /**
     * 拥有ADMIN和USER角色可以访问
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回数据MAP
     */
    @PreAuthorize("hasRole('ADMIN') and hasRole('USER')")
    @RequestMapping(value = "/menuList",method = RequestMethod.GET)
    public Map<String,Object> menuList(){
        Map<String,Object> result = new HashMap<>();
        List<SysMenuEntity> sysMenuEntityList = sysMenuService.list();
        result.put("title","拥有用户和管理员角色都可以查看");
        result.put("data",sysMenuEntityList);
        return ResultUtil.resultSuccess(result);
    }

通常情况下使用hasRole和hasAnyRole基本可以满足大部分鉴权需求,但是有时候面对更复杂的场景上述常规表示式无法完成权限认证,Security也为我们提供了解决方案.通过hasPermission()来扩展表达式.使用hasPermission()首先要实现PermissionEvaluator接口

/**
 * 自定义权限注解验证
 * @Author Sans
 * @CreateTime 2019/10/6 13:31
 */
@Component
public class UserPermissionEvaluator implements PermissionEvaluator {
    @Autowired
    private SysUserService sysUserService;
    /**
     * hasPermission鉴权方法
     * 这里仅仅判断PreAuthorize注解中的权限表达式
     * 实际中可以根据业务需求设计数据库通过targetUrl和permission做更复杂鉴权
     * 当然targetUrl不一定是URL可以是数据Id还可以是管理员标识等,这里根据需求自行设计
     * @Author Sans
     * @CreateTime 2019/10/6 18:25
     * @Param  authentication  用户身份(在使用hasPermission表达式时Authentication参数默认会自动带上)
     * @Param  targetUrl  请求路径
     * @Param  permission 请求路径权限
     * @Return boolean 是否通过
     */
    @Override
    public boolean hasPermission(Authentication authentication, Object targetUrl, Object permission) {
        // 获取用户信息
        SelfUserEntity selfUserEntity =(SelfUserEntity) authentication.getPrincipal();
        // 查询用户权限(这里可以将权限放入缓存中提升效率)
        Set<String> permissions = new HashSet<>();
        List<SysMenuEntity> sysMenuEntityList = sysUserService.selectSysMenuByUserId(selfUserEntity.getUserId());
        for (SysMenuEntity sysMenuEntity:sysMenuEntityList) {
            permissions.add(sysMenuEntity.getPermission());
        }
        // 权限对比
        if (permissions.contains(permission.toString())){
            return true;
        }
        return false;
    }
    @Override
    public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
        return false;
    }
}

在请求方法上添加hasPermission示例

    /**
     * 拥有sys:user:info权限可以访问
     * hasPermission 第一个参数是请求路径 第二个参数是权限表达式
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回数据MAP
     */
    @PreAuthorize("hasPermission('/admin/userList','sys:user:info')")
    @RequestMapping(value = "/userList",method = RequestMethod.GET)
    public Map<String,Object> userList(){
        Map<String,Object> result = new HashMap<>();
        List<SysUserEntity> sysUserEntityList = sysUserService.list();
        result.put("title","拥有sys:user:info权限都可以查看");
        result.put("data",sysUserEntityList);
        return ResultUtil.resultSuccess(result);
    }

hasPermission可以也可以和其他表达式联合使用

    /**
     * 拥有ADMIN角色和sys:role:info权限可以访问
     * @Author Sans
     * @CreateTime 2019/10/2 14:22
     * @Return Map<String,Object> 返回数据MAP
     */
    @PreAuthorize("hasRole('ADMIN') and hasPermission('/admin/adminRoleList','sys:role:info')")
    @RequestMapping(value = "/adminRoleList",method = RequestMethod.GET)
    public Map<String,Object> adminRoleList(){
        Map<String,Object> result = new HashMap<>();
        List<SysRoleEntity> sysRoleEntityList = sysRoleService.list();
        result.put("title","拥有ADMIN角色和sys:role:info权限可以访问");
        result.put("data",sysRoleEntityList);
        return ResultUtil.resultSuccess(result);
    }

七.测试

创建账户这里用户加密使用了Security推荐的bCryptPasswordEncoder方法

 

   /**
     * 注册用户
     */
    @Test
    public void contextLoads() {
        // 注册用户
        SysUserEntity sysUserEntity = new SysUserEntity();
        sysUserEntity.setUsername("sans");
        sysUserEntity.setPassword(bCryptPasswordEncoder.encode("123456"));
        // 设置用户状态
        sysUserEntity.setStatus("NORMAL");
        sysUserService.save(sysUserEntity);
        // 分配角色 1:ADMIN 2:USER
        SysUserRoleEntity sysUserRoleEntity = new SysUserRoleEntity();
        sysUserRoleEntity.setRoleId(2L);
        sysUserRoleEntity.setUserId(sysUserEntity.getUserId());
        sysUserRoleService.save(sysUserRoleEntity);
    }

登录USER角色账号,登录成功后我们会获取到身份认证的Token

访问USER角色的接口,把上一步获取到的Token设置在Headers中,Key为Authorization,我们之前实现的JWTAuthenticationTokenFilter拦截器会根据请求头中的Authorization获取并解析Token

使用USER角色Token访问ADMIN角色的接口,会被拒绝,告知未授权(暂无权限会进入我们定义的UserAuthAccessDeniedHandler这个类进行处理)

更换ADMIN角色进行登录并访问ADMIN接口
