How to unsecure a method with Spring security

Question

I have implemented Spring Security for a RESTful web service project. It has Request Mappings with same url patterns but with different Request Method types.

@RequestMapping(value = "/charity/accounts", method = RequestMethod.POST)
public AccountResponseDto createAccount(HttpServletResponse response, @RequestBody AccountRequestDto requestDTO) {
    // some logics here
}

@RequestMapping(value = "/charity/accounts", method = RequestMethod.GET)
public AccountResponseDto getAccount(HttpServletResponse response) {
    // some logics here
}

@RequestMapping(value = "/charity/accounts", method = RequestMethod.PUT)
public void updateAccount(HttpServletResponse response, @RequestBody AccountRequestDto requestDTO){
    // some logics here
}

Currently all of these methods require Authorization to execute, but I need to remove authorization for createAccount(...) method. Are there annotation based solutions?

Note: I need a solution that will not effect to do changes for url patterns, as it will impact in many other modules.

Below is a sample configuration which would permit requests for signup and about:

@EnableWebSecurity
@Configuration
public class CustomWebSecurityConfigurerAdapter extends
   WebSecurityConfigurerAdapter {
  @Autowired
  public void configureGlobal(AuthenticationManagerBuilder auth) {
    auth
      .inMemoryAuthentication()
        .withUser("user")  // #1
          .password("password")
          .roles("USER")
          .and()
        .withUser("admin") // #2
          .password("password")
          .roles("ADMIN","USER");
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http
      .authorizeUrls()
        .antMatchers("/signup","/about").permitAll();
  }
}

You can refer Spring Security Java Config for detailed information.

A suggestion on your Controller. If all requests prefixed with /charity to be handled by CharityController, you can map requests in the below way:

@Controller
@RequestMapping(value="/charity")
class CharityController {
            @RequestMapping(value = "/accounts", method = RequestMethod.GET)
            public AccountResponseDto getAccount(HttpServletResponse response){

            }
}

Update

The following should work for you.

protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers(HttpMethod.POST, new String [] {"/charity/accounts", "/charity/people"}).permitAll();
}
