Spring Security CORS 过滤器不起作用

Question

我正在使用带有 OAuth2（版本：4.0.4.RELEASE）和 spring（版本：4.3.1.RELEASE）的 Spring Security。

我正在使用 Angular 开发前端，并且正在使用 grunt connect:dev (http://127.0.0.1:9000)。当我尝试通过本地主机地址登录时，一切正常，但从其他我收到错误：

“XMLHttpRequest 无法加载 http://localhost:8084/oauth/token?client_id=MY_CLIENT_ID。对预检请求的响应未通过访问控制检查：请求的资源上不存在 'Access-Control-Allow-Origin' 标头。因此不存在来源 'http://127.0.0.1:9000'允许访问。响应的 HTTP 状态代码为 401。"

我已经在 WebMvcConfigurerAdapter 中配置了映射（Overrided public void addCorsMappings(CorsRegistry registry)）（如下所示），但它仍然不适用于http://127.0.0.1:9000。

    registry.addMapping("/**")
            .allowedOrigins("http://127.0.0.1:9000")
            .allowedMethods("POST", "OPTIONS", "GET", "DELETE", "PUT")
            .allowedHeaders("X-Requested-With,Origin,Content-Type,Accept,Authorization")
            .allowCredentials(true).maxAge(3600);

配置基于：https://spring.io/guides/gs/rest-service-cors/

请给我指出正确的方向来解决这个问题。

Answer 1

下面对我有用。

  import org.springframework.context.annotation.Configuration;
  import org.springframework.web.servlet.config.annotation.CorsRegistry;
  import org.springframework.web.servlet.config.annotation.EnableWebMvc;
  import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

  @Configuration
  @EnableWebMvc
  public class MvcConfig implements WebMvcConfigurer {

  @Override
  public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedMethods("HEAD", "GET", "PUT", "POST", "DELETE", "PATCH");     
  }
}

抱歉长时间回复。我通过如下配置我的 CORS 过滤器解决了这个问题：

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CORSFilter implements Filter {

    private static final Logger LOGGER = LogManager.getLogger(CORSFilter.class.getName());

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void doFilter(final ServletRequest req, final ServletResponse res, final FilterChain chain) throws IOException, ServletException {
        final HttpServletRequest request = (HttpServletRequest) req;
        final HttpServletResponse response = (HttpServletResponse) res;
        final String origin = ((HttpServletRequest) req).getHeader("Origin");

        if (ofNullable(origin).isPresent() && origin.equals("http://127.0.0.1:9000")) {
            LOGGER.info("CORSFilter run");
            response.addHeader("Access-Control-Allow-Origin", "http://127.0.0.1:9000");
            response.addHeader("Access-Control-Allow-Credentials", "true");

            if (request.getHeader("Access-Control-Request-Method") != null && "OPTIONS".equals(request.getMethod())) {
                response.addHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
                response.addHeader("Access-Control-Allow-Headers", "X-Requested-With,Origin,Content-Type,Accept,Authorization");
                response.setStatus(200);
            }
        }
        chain.doFilter(addNessesaryHeaders(request), response);
    }


    private MutableHttpServletRequest addNessesaryHeaders(final HttpServletRequest request) {
        final MutableHttpServletRequest mutableRequest = new MutableHttpServletRequest(request);
        mutableRequest.putHeader("Accept", "application/json");
        mutableRequest.putHeader("Authorization", "Basic" + " bXVzaWNzY2hvb2w6");
        return mutableRequest;
    }

    @Override
    public void destroy() {
    }
}

希望您很久以前就找到了答案，但如果没有（如果其他人发现这个问题像我一样搜索）：

问题在于 Spring Security 使用过滤器进行操作，这些过滤器通常优先于用户定义的过滤器、@CrossOrigin 和类似的注释等。

对我有用的是将 CORS 过滤器定义为具有最高优先级的 bean，正如 here 所建议的那样。

@Configuration
public class MyConfiguration {

    @Bean
    public FilterRegistrationBean corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("http://127.0.0.1:9000");
        config.setAllowedMethods(Arrays.asList("POST", "OPTIONS", "GET", "DELETE", "PUT"));
        config.setAllowedHeaders(Arrays.asList("X-Requested-With", "Origin", "Content-Type", "Accept", "Authorization"));
        source.registerCorsConfiguration("/**", config);
        FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
        bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
        return bean;
    }
}

你可以试试这样的

@Configuration
public class CorsConfig {
   @Bean
   public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
          @Override
          public void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**")
                    .allowedMethods(HttpMethod.OPTIONS.name(),
                            HttpMethod.PATCH.name(),
                            HttpMethod.PUT.name(),
                            HttpMethod.DELETE.name(),
                            HttpMethod.GET.name(),
                            HttpMethod.POST.name())
                    .maxAge(360);
            }
       };
   }
}

注意：Spring 版本应为 4.2 或更高版本
