mybatis 实体嵌套查询

本例子只是一个实体类嵌套另外一个或者多个实体类。在实体类嵌套一个实体列表的我还没研究出来。

首先上实体类：

public class AppPost {
    private String postId;
    private String postTitle;
    private int upTime;
    private int postType;
    private int pointsNum;
    private int collectionNum;
    private int replyNum;
    private int transferNum;
    private int isHost;
    private int contentType;
    private AppUserMini user;
}


public class AppUserMini {
    private String userId;
    private String userName;
    private Integer userSex;
    private Integer userAge;
    private String userImg;
    private String userAddress;
}

然后其他乱七八糟的就不说了，直接上xml的代码：

    
    
    
    
    
    
    
    
    
    


    
  

  
    
    
    
    
    
    
  

  
    select a.post_id,a.post_title,a.up_time,a.post_type,a.points_num,a.collection_num,a.reply_num,a.transfer_num,a.is_hot,a.content_type,b.user_id,b.user_name,b.user_sex,b.user_age,b.user_img,b.user_address
    from service_post a,sys_user b
    where a.post_id = #{postId,jdbcType=INTEGER} AND a.user_id=b.user_id
  

估计看代码就动了，我也不多逼逼了！
