Spring MVC 中的 CORS 配置详解

为了解决跨域问题,可以在 Spring ServletFilter 中添加 CORS 配置。以下是详细的配置步骤:

  • 添加允许的域名:在 CORS 配置中指定需要跨域的域名。如:
  • corsConfiguration.addAllowedOrigin("http://www.example.com");
    1. 设置 cookie 域名:如果需要跨域时携带 cookie,需要明确指定域名:
    2. corsConfiguration.addAllowedOrigin("http://www.example.com");
      1. 启用 cookie 理 Localization:允许跨域请求携带 cookie:
      2. corsConfiguration.setAllowCredentials(true);
        1. 允许请求方法:指定允许的 HTTP 请求方法,* 表示全部方法:
        2. corsConfiguration.addAllowedMethod("*");
          1. 允许请求头字段:设置允许的头字段,* 表示全部字段:
          2. corsConfiguration.addAllowedHeader("*");
            1. 创建配置源:将 CORS 配置注册到路由中:
            2. UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();source.registerCorsConfiguration("/**", configuration);
              1. 返回 CORS 过滤器:最后,返回配置好的 CORS 过滤器:
              2. return new CorsFilter(source);

                以上配置依次设置了域名、 cookie 执裁、请求方法和请求头字段等参数,确保应用程序能够正常处理跨域请求。
