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

Posted 2021-01-31 skyxia

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。
