使用Spring Security授权POST端点

Question

我的Spring项目/public/signUser中有一个REST端点;我想在没有凭据的情况下授权此端点，以便允许创建用户。但是，如果我尝试对POST端点发出signUser请求，则会收到未经授权的错误。我想为此端点禁用身份验证。

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Inject
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
            .passwordEncoder(new BCryptPasswordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http .httpBasic().and()
            .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
            .authorizeRequests()
                .antMatchers(HttpMethod.POST, "/public/signUser").permitAll()
                .antMatchers("/public/hello", "/swagger-ui/**", "/api-docs/**").permitAll()
                .antMatchers("/protected/**").authenticated()
                .and()
            .httpBasic()
                .realmName("PlcManager")
                .and()
            .csrf()
                .disable();
    }
}
