org.apache.ibatis.executor.ExecutorException: No constructor found in问题解决

springboot中整合mybatis的下面来配置报错：

因为谢了有参构造，没写无参构造；在model 中添加无参构造；

package com.mybatis.neo.mybatisdemo.model;
import com.mybatis.neo.mybatisdemo.enums.UserSexEnum;
import lombok.Data;
import java.io.Serializable;
	//使用lombok 、枚举UserSexEnum 
public @Data class User implements Serializable {
	private static final long serialVersionUID = 1L;
	private Long id;
	private String userName;
	private String passWord;
	private UserSexEnum userSex;
	private String nickName;
	//
	public User() {
	}
	public User(String userName, String passWord, UserSexEnum userSex) {
		this.userName = userName;
		this.passWord = passWord;
		this.userSex = userSex;
	}
}

小结：
若有参构造存在，无参构造必然存在；
