JavaSpringSecurity+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:
@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-resourcesv2/api-docs
-*.js
-*.CSS
-*.png
-*.ico
-/webjars/springfox-swagger-ui
@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:
@Getter
@Setter
@ConfigurationProperties(prefix = "secure.ignored")
publicclass IgnoreUrlsConfig {
private List<String> urls = new ArrayList<>();
}
SecurityConfig中的代码:
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();
}
}
