我们在现有项目中添加了 Spring Security。

从这一刻起，我们的服务器收到 401 No 'Access-Control-Allow-Origin' header is present on the requested resource 错误。

这是因为响应中没有附加 Access-Control-Allow-Origin header 。为了解决这个问题，我们在注销过滤器之前的 Filter 链中添加了我们自己的过滤器，但该过滤器不适用于我们的请求。

我们的错误:

XMLHttpRequest cannot load http://localhost:8080/getKunden. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin http://localhost:3000 is therefore not allowed access. The response had HTTP status code 401.

我们的安全配置:

@EnableWebSecurity
@Configuration
@ComponentScan("com.company.praktikant")
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

@Autowired
private MyFilter filter;

@Override
public void configure(HttpSecurity http) throws Exception {
    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    final CorsConfiguration config = new CorsConfiguration();

    config.addAllowedOrigin("*");
    config.addAllowedHeader("*");
    config.addAllowedMethod("GET");
    config.addAllowedMethod("PUT");
    config.addAllowedMethod("POST");
    source.registerCorsConfiguration("/**", config);
    http.addFilterBefore(new MyFilter(), LogoutFilter.class).authorizeRequests()
            .antMatchers(HttpMethod.OPTIONS, "/*").permitAll();
}

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
}
}

我们的过滤器

@Component
public class MyFilter extends OncePerRequestFilter {

@Override
public void destroy() {

}

private String getAllowedDomainsRegex() {
    return "individual / customized Regex";
}

@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
        throws ServletException, IOException {

    final String origin = "http://localhost:3000";

    response.addHeader("Access-Control-Allow-Origin", origin);
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");
    response.setHeader("Access-Control-Allow-Credentials", "true");
    response.setHeader("Access-Control-Allow-Headers",
            "content-type, x-gwt-module-base, x-gwt-permutation, clientid, longpush");

    filterChain.doFilter(request, response);

}
}

我们的应用程序

@SpringBootApplication
public class Application {
public static void main(String[] args) {
    final ApplicationContext ctx = SpringApplication.run(Application.class, args);
    final AnnotationConfigApplicationContext annotationConfigApplicationContext = new AnnotationConfigApplicationContext();
    annotationConfigApplicationContext.register(CORSConfig.class);
    annotationConfigApplicationContext.refresh();
}
}

我们的过滤器是从 spring-boot 注册的:

2016-11-04 09:19:51.494 INFO 9704 --- [ost-startStop-1] o.s.b.w.servlet.FilterRegistrationBean : Mapping filter: 'myFilter' to: [/*]

我们生成的过滤器链:

回应: Response headers

我们也尝试了 spring 的解决方案，但没有奏效!我们 Controller 中的注解 @CrossOrigin 也没有帮助。

编辑 1:

尝试了@Piotr Sołtysiak 的解决方案。 cors 过滤器未列在生成的过滤器链中，我们仍然得到相同的错误。

顺便说一句，我们使用的是 spring-security 版本 4.1.3。!

最佳答案

从 Spring Security 4.1 开始，这是使 Spring Security 支持 CORS 的正确方法(Spring Boot 1.4/1.5 也需要):

@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {

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

和:

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
//        http.csrf().disable();
        http.cors();
    }

    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        final CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(ImmutableList.of("*"));
        configuration.setAllowedMethods(ImmutableList.of("HEAD",
                "GET", "POST", "PUT", "DELETE", "PATCH"));
        // setAllowCredentials(true) is important, otherwise:
        // The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'.
        configuration.setAllowCredentials(true);
        // setAllowedHeaders is important! Without it, OPTIONS preflight request
        // will fail with 403 Invalid CORS request
        configuration.setAllowedHeaders(ImmutableList.of("Authorization", "Cache-Control", "Content-Type"));
        final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
}

不要不要做以下任何一种尝试解决问题的错误方法:

• http.authorizeRequests().antMatchers(HttpMethod.OPTIONS, "/**").permitAll();
• web.ignoring().antMatchers(HttpMethod.OPTIONS);
