MyBatis There is no getter for property named ‘xxx‘ in ‘class xxx‘问题解决

org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named ‘dataTime’ in ‘class com.dto.UserDto’

1、Mapper文件中参数出现了dataTime，但是实体类UserDto中却没有dataTime，两边无法映射导致报错。

    
        INSERT INTO t_user(user_id,user_name,data_time)
        VALUES (#{item.userId,item.userName,item.dataTime})
    

public class UserDto {
    private Long userId;
    private String userName;
}

解决办法：

（1）Mapper文件去掉dataTime，实体类保持不变。

    
        INSERT INTO t_user(user_id,user_name)
        VALUES (#{item.userId,item.userName})
    

（2）实体中添加dataTime，Mapper文件保持不变。

public class UserDto {
    private Long userId;
    private String userName;
    private Date dataTime;
}
