Java SpringSecurity+JWT实现登录认证

前言:

学习过我的mall项目的应该知道, mall-admin 模块是使用SpringSecurity+JWT来实现登录认证的,而 mall-portal 模块是使用的SpringSecurity基于Session的默认机制来实现登陆认证的。很多小伙伴都找不到 mall-portal 的登录接口,最近我把这两个模块的登录认证给统一了,都使用SpringSecurity+JWT的形式实现。主要是通过把登录认证的通用逻辑抽取到了 mall-security 模块来实现的,下面我们讲讲如何使用 mall-security 模块来实现登录认证,仅需四步即可。

整合步骤

这里我们以 mall-portal 改造为例来说说如何实现。

第一步,给需要登录认证的模块添加 mall-security 依赖:

?

< dependency >

     < groupId >com.macro.mall</ groupId >

     < artifactId >mall-security</ artifactId >

</ dependency >

第二步,添加MallSecurityConfig配置类,继承 mall-security 中的SecurityConfig配置,并且配置一个UserDetailsService接口的实现类,用于获取登录用户详情:

/**

  * mall-security模块相关配置

  * Created by macro on 2019/11/5.

  */

@Configuration

@EnableWebSecurity

@EnableGlobalMethodSecurity (prePostEnabled= true )

publicclass MallSecurityConfig extends SecurityConfig {

     @Autowired

     private UmsMemberService memberService;

 

     @Bean

     public UserDetailsService userDetailsService() {

         //获取登录用户信息

         return username -> memberService.loadUserByUsername(username);

     }

}

第三步,在application.yml中配置下不需要安全保护的资源路径:

       -/**/ *.ico

       -/webjars/springfox-swagger-ui/**

       -/druid/**

       -/actuator/**

       -/sso/**

       -/home/**

第四步,在UmsMemberController中实现登录和刷新token的接口:

/**

  * 会员登录注册管理Controller

  * Created by macro on 2018/8/3.

  */

@Controller

@Api (tags = "UmsMemberController" , description = "会员登录注册管理" )

@RequestMapping ( "/sso" )

publicclass UmsMemberController {

     @Value ( "${jwt.tokenHeader}" )

     private String tokenHeader;

     @Value ( "${jwt.tokenHead}" )

     private String tokenHead;

     @Autowired

     private UmsMemberService memberService;

 

     @ApiOperation ( "会员登录" )

     @RequestMapping (value = "/login" , method = RequestMethod.POST)

     @ResponseBody

     public CommonResult login( @RequestParam String username,

                               @RequestParam String password) {

         String token = memberService.login(username, password);

         if (token == null ) {

             return CommonResult.validateFailed( "用户名或密码错误" );

         }

         Map<String, String> tokenMap = new HashMap<>();

         tokenMap.put( "token" , token);

         tokenMap.put( "tokenHead" , tokenHead);

         return CommonResult.success(tokenMap);

     }

 

     @ApiOperation (value = "刷新token" )

     @RequestMapping (value = "/refreshToken" , method = RequestMethod.GET)

     @ResponseBody

     public CommonResult refreshToken(HttpServletRequest request) {

         String token = request.getHeader(tokenHeader);

         String refreshToken = memberService.refreshToken(token);

         if (refreshToken == null ) {

             return CommonResult.failed( "token已经过期!" );

         }

         Map<String, String> tokenMap = new HashMap<>();

         tokenMap.put( "token" , refreshToken);

         tokenMap.put( "tokenHead" , tokenHead);

         return CommonResult.success(tokenMap);

     }

}

实现原理

将SpringSecurity+JWT的代码封装成通用模块后,就可以方便其他需要登录认证的模块来使用,下面我们来看看它是如何实现的,首先我们看下 mall-security 的目录结构。

mall-security

├── component

|    ├── JwtAuthenticationTokenFilter -- JWT登录授权过滤器

|    ├── RestAuthenticationEntryPoint -- 自定义返回结果:未登录或登录过期

|    └── RestfulAccessDeniedHandler -- 自定义返回结果:没有权限访问时

├── config

|    ├── IgnoreUrlsConfig -- 用于配置不需要安全保护的资源路径

|    └── SecurityConfig -- SpringSecurity通用配置

└── util

      └── JwtTokenUtil -- JWT的token处理工具类

做了哪些变化

其实我也就添加了两个类,一个IgnoreUrlsConfig,用于从application.yml中获取不需要安全保护的资源路径。一个SecurityConfig提取了一些SpringSecurity的通用配置。
