在Spring Boot中添加facebook social后，我无法使用任何控制器的post方法

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable() // 禁用CSRF保护
            .authorizeRequests()
                .anyRequest().authenticated()
                .and()
            .oauth2Login()
                .loginPage("/login")
                .permitAll();
    }
}

@Configuration
public class CorsConfig {

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurer() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**")
                        .allowedOrigins("*")
                        .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
                        .allowedHeaders("*")
                        .allowCredentials(true);
            }
        };
    }
}

@RestController
public class MyController {

    @PostMapping("/my-endpoint")
    public String myEndpoint() {
        return "Hello, World!";
    }
}
