我的配置如下，但是返回的json中么有验证的详细信息，请问什么原因？

rest client：

###
# @name register
POST {{host}}/authorize/register HTTP/1.1
Content-Type: application/json

{
    "name": "aa"
}

返回的JSON：

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests(req -> req

                        .antMatchers("/admin/**").hasRole("ADMIN")
                        .antMatchers("/api/**").hasRole("USER")
                        .anyRequest().authenticated())
                .addFilterAt(restAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
                .csrf(csrf -> csrf.disable());

API：

@RestController
@RequestMapping("/authorize")
public class AuthorizeController {
    @PostMapping("register")
    public UserDto register(@Valid @RequestBody UserDto userDto) {
        return userDto;
    }
}
