学习 ruoyi-vue-pro 的 yudao-framework / yudao-spring-boot-starter-security 模块
学习流程

config: 用来配置安全相关的权限等
core: 一些安全的业务逻辑
META-INF: 配置spring的自动import类

org.springframework.boot.autoconfigure.AutoConfiguration.imports
自动导入下面两个类
cn.iocoder.yudao.framework.security.config.YudaoSecurityAutoConfiguration
cn.iocoder.yudao.framework.security.config.YudaoWebSecurityConfigurerAdapter
cn.iocoder.yudao.framework.security.config.YudaoSecurityAutoConfiguration
注入bean, 原来的注释很详细了

自定义 SecurityFilterChain
@Bean protected SecurityFilterChain filterChain(HttpSecurity httpSecurity) throws Exception { // 登出 httpSecurity // 开启跨域 .cors().and() // CSRF 禁用,因为不使用 Session .csrf().disable() // 基于 token 机制,所以不需要 Session .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and() .headers().frameOptions().disable().and() // 一堆自定义的 Spring Security 处理器 .exceptionHandling().authenticationEntryPoint(authenticationEntryPoint) .accessDeniedHandler(accessDeniedHandler); // 登录、登录暂时不使用 Spring Security 的拓展点,主要考虑一方面拓展多用户、多种登录方式相对复杂,一方面用户的学习成本较高 // 获得 @PermitAll 带来的 URL 列表,免登录 Multimap<HttpMethod, String> permitAllUrls = getPermitAllUrlsFromAnnotations(); // 设置每个请求的权限 httpSecurity // ①:全局共享规则 .authorizeRequests() // 1.1 静态资源,可匿名访问 .antMatchers(HttpMethod.GET, "/*.html", "/**/*.html", "/**/*.css", "/**/*.js").permitAll() // 1.2 设置 @PermitAll 无需认证 .antMatchers(HttpMethod.GET, permitAllUrls.get(HttpMethod.GET).toArray(new String[0])).permitAll() .antMatchers(HttpMethod.POST, permitAllUrls.get(HttpMethod.POST).toArray(new String[0])).permitAll() .antMatchers(HttpMethod.PUT, permitAllUrls.get(HttpMethod.PUT).toArray(new String[0])).permitAll() .antMatchers(HttpMethod.DELETE, permitAllUrls.get(HttpMethod.DELETE).toArray(new String[0])).permitAll() // 1.3 基于 yudao.security.permit-all-urls 无需认证 .antMatchers(securityProperties.getPermitAllUrls().toArray(new String[0])).permitAll() // 1.4 设置 App API 无需认证 .antMatchers(buildAppApi("/**")).permitAll() // 1.5 验证码captcha 允许匿名访问 .antMatchers("/captcha/get", "/captcha/check").permitAll() // 1.6 webSocket 允许匿名访问 .antMatchers("/websocket/message").permitAll() // ②:每个项目的自定义规则 .and().authorizeRequests(registry -> // 下面,循环设置自定义规则 authorizeRequestsCustomizers.forEach(customizer -> customizer.customize(registry))) // ③:兜底规则,必须认证 .authorizeRequests() .anyRequest().authenticated() ; // 添加 Token Filter httpSecurity.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class); return httpSecurity.build(); }
