2. 풀이

- UserSearch.java

package com.example.jpa.sample.user.model;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

@AllArgsConstructor
@NoArgsConstructor
@Builder
@Data
public class UserSearch {

    private String email;
    private String name;
    private String phone;
}

- ApiAdminUserController.java

package com.example.jpa.sample.user.controller;

import com.example.jpa.sample.user.entity.User;
import com.example.jpa.sample.user.model.ResponseMessage;
import com.example.jpa.sample.user.model.UserSearch;

        }

        return ResponseEntity.ok().body(ResponseMessage.success(user));
