Question
We added Spring Security
to our existing project.
From this moment on we get a 401 No 'Access-Control-Allow-Origin' header is present on the requested resource
error from the our server.
That's because no Access-Control-Allow-Origin
header is attached to the
response. To fix this we added our own filter which is in the Filter
chain
before the logout filter, but the filter does not apply for our requests.
Our Error:
XMLHttpRequest cannot load
http://localhost:8080/getKunden
. No 'Access- Control-Allow-Origin' header is present on the requested resource. Originhttp://localhost:3000
is therefore not allowed access. The response had HTTP status code 401.
Our Security configuration:
@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 {
}
}
Our filter
@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);
}
}
Our Application
@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();
}
}
Our filter is registered from spring-boot:

The Response: Response headers
We tried the solution from spring as well but it didn't work! The annotation @CrossOrigin in our controller didn't help either.
Edit 1:
Tried the solution from @Piotr Sołtysiak. The cors filter isn't listed in the generated filter chain and we still get the same error.

Btw we are using spring-security version 4.1.3.!
Answer
Ok, after over 2 days of searching we finally fixed the problem. We deleted all our filter and configurations and instead used this 5 lines of code in the application class.
@SpringBootApplication
public class Application {
public static void main(String[] args) {
final ApplicationContext ctx = SpringApplication.run(Application.class, args);
}
@Bean
public WebMvcConfigurer corsConfigurer() {
return new WebMvcConfigurerAdapter() {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("http://localhost:3000");
}
};
}
}
