Java SpringSecurity+JWT实现登录认证
作者:梦想de星空
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:
secure: ignored: urls:#安全路径白名单 -/swagger-ui.html -/swagger-resources/** -/swagger/** -/**/v2/api-docs -/**/*.js -/**/*.css -/**/*.png -/**/*.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。
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。
IgnoreUrlsConfig中的代码:
/** * 用于配置不需要保护的资源路径 * Created by macro on 2018/11/5. */ @Getter @Setter @ConfigurationProperties(prefix = "secure.ignored") publicclass IgnoreUrlsConfig { private List<String> urls = new ArrayList<>(); }
SecurityConfig中的代码:
/** * 对SpringSecurity的配置的扩展,支持自定义白名单资源路径和查询用户逻辑 * Created by macro on 2019/11/5. */ publicclass SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity httpSecurity) throws Exception { ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = httpSecurity .authorizeRequests(); //不需要保护的资源路径允许访问 for (String url : ignoreUrlsConfig().getUrls()) { registry.antMatchers(url).permitAll(); } //允许跨域请求的OPTIONS请求 registry.antMatchers(HttpMethod.OPTIONS) .permitAll(); // 任何请求需要身份认证 registry.and() .authorizeRequests() .anyRequest() .authenticated() // 关闭跨站请求防护及不使用session .and() .csrf() .disable() .sessionManagement() .sessionCreationPolicy(SessionCreationPolicy.STATELESS) // 自定义权限拒绝处理类 .and() .exceptionHandling() .accessDeniedHandler(restfulAccessDeniedHandler()) .authenticationEntryPoint(restAuthenticationEntryPoint()) // 自定义权限拦截器JWT过滤器 .and() .addFilterBefore(jwtAuthenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class); } @Override protected void configure(AuthenticationManagerBuilder auth) throws Exception { auth.userDetailsService(userDetailsService()) .passwordEncoder(passwordEncoder()); } @Bean public PasswordEncoder passwordEncoder() { returnnew BCryptPasswordEncoder(); } @Bean public JwtAuthenticationTokenFilter jwtAuthenticationTokenFilter() { returnnew JwtAuthenticationTokenFilter(); } @Bean @Override public AuthenticationManager authenticationManagerBean() throws Exception { returnsuper.authenticationManagerBean(); } @Bean public RestfulAccessDeniedHandler restfulAccessDeniedHandler() { returnnew RestfulAccessDeniedHandler(); } @Bean public RestAuthenticationEntryPoint restAuthenticationEntryPoint() { returnnew RestAuthenticationEntryPoint(); } @Bean public IgnoreUrlsConfig ignoreUrlsConfig() { returnnew IgnoreUrlsConfig(); } @Bean public JwtTokenUtil jwtTokenUtil() { returnnew JwtTokenUtil(); } }
