spring security 403 error

Question

I'm trying to secure my website using Spring security following the guides on the web. So on my server side the WebSecurityConfigurerAdapter and controller looks like this

@Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter implements ApplicationContextAware {  @Override protected void registerAuthentication(AuthenticationManagerBuilde r authManagerBuilder) throws Exception { authManagerBuilder.inMemoryAuthentication() .withUser("user").password("password").roles("ADMI N"); } }  @Controller //@RequestMapping("/course") public class CourseController implements ApplicationContextAware{  @RequestMapping(value="/course", method = RequestMethod.GET, produces="application/json") public @ResponseBody List<Course> get(// The critirion used to find. @RequestParam(value="what", required=true) String what, @RequestParam(value="value", required=true) String value) { //..... }  @RequestMapping(value="/course", method = RequestMethod.POST, produces="application/json") public List<Course> upload(@RequestBody Course[] cs) { } } 

What confused me very much is the server does not respond to the POST/DELETE method, while the GET method works fine. BTW, I'm using RestTemplate on the client side. Exceptions are:

Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 403 Forbidden     at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)     at org.springframework.web.client.RestTemplate.handleResponseError(RestTemplate.java:574)     at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:530)     at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:487)     at org.springframework.web.client.RestTemplate.delete(RestTemplate.java:385)     at hello.Application.createRestTemplate(Application.java:149)     at hello.Application.main(Application.java:99) 

I've searched the internet for days. Still don't have a clue. Please help. Thanks so much

Answer 1

The issue is likely due to CSRF protection. If users will not be using your application in a web browser, then it is safe to disable CSRF protection. Otherwise you should ensure to include the CSRF token in the request.

To disable CSRF protection you can use the following:

@Configuration @EnableWebSecurity public class WebSecurityConfig     extends WebSecurityConfigurerAdapter implements ApplicationContextAware {      @Override     protected void configure(HttpSecurity http) throws Exception {         http             // ...             .csrf().disable();     }      @Override     protected void registerAuthentication(AuthenticationManagerBuilder authManagerBuilder) throws Exception {         authManagerBuilder             .inMemoryAuthentication()                 .withUser("user").password("password").roles("ADMIN");     } }

The issue may be related to CSRF or CORS Security Protection.

• FOR CSRF: You can disable it if the application users did not use it from browsers.
• For CORS: You can specify the origin and allow HTTP Methods.

The below code disable CSRF and allow all origins and HTTP methods. so be aware when using it.

@Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter  implements WebMvcConfigurer {      @Override     protected void configure(HttpSecurity http) throws Exception {         http.csrf().disable();     }      @Override     public void addCorsMappings(CorsRegistry registry) {         registry.addMapping("/**").allowedMethods("*");     }  }
