There is no getter for property named 'user' in 'class com.jyr.wh.domain.User' 异常

今天在使用mybatis时，出现了一个问题：There is no getter for property named 'user' in 'class com.jyr.wh.domain.User，现记录下来

使用注解的形式写sql语名，参数为一个对象

以下为正确写法：

@Insert(
    "INSERT INTO t_user(openId,nickName,gender,language,city,province,country," +
            "avatarUrl,unionId,appid,timestamp) " +
    "VALUES(#{openId},#{nickName},#{gender},#{language},#{city},#{province},#{country}," +
            "#{avatarUrl},#{unionId},#{watermark.appid},#{watermark.timestamp})"
)
int insert(User user);

 

 

 

 

 

import java.io.Serializable;

public class User implements Serializable {

    private String openId;
    private String nickName;
    private String gender;
    private String language;
    private String city;
    private String province;
    private String country;
    private String avatarUrl;//头像
    private String unionId;
    private WaterMark watermark;
    
    public class WaterMark{
        private String appid;
        private String timestamp;
        }
    }
}

以上省略get、set方法

 

 

 

 

 

 

 

 

 

 

 

 

报错找不到user那是因为我的sql写错了，在values的参数中加了形参

@Insert(
    "INSERT INTO t_user(openId,nickName,gender,language,city,province,country," +
            "avatarUrl,unionId,appid,timestamp) " +
    "VALUES(#{user.openId},#{user.nickName},#{user.gender},#{user.language},#{user.city},#{user.province},#{user.country}," +
            "#{user.avatarUrl},#{user.unionId},#{user.watermark.appid},#{user.watermark.timestamp})"
)
int insert(User user);

 

 

 

 

 

在使用注解方式时形参不用写，只写传的对象的属性即可，加上会报以上错误。
