mybatis中collection标签的使用

看图说话

解释：

当一个查询里有对象的时候，实体映射可以用Collection标签，属性值
property实体类里的对象名，column数据库字段，ofType指实体类中select 标签返回类型，一般为map.
javaType指实体类中的对象类型，select查询语句，查询的是文本中select标签,一般为java.util.List

  =========================================================
  
    SELECT
    pr.id,pr.user_id,pr.user_name,pr.fllownum,pr.funnum,pr.stat,pr.rpnum,pr.other,pr.pronum
    FROM
    RDA_UC_FLLOWER pr
    WHERE
    pr.user_id=#{id}

  

实体类如下，自己分析
package com.reada.pojo;

import java.util.Date;
import java.util.List;

public class ReadaUser {
    private Integer id;

    private String username;

    private String realName;

    private String nick;

    private String gender;

    private String area;

    private String phone;

    private Date birthday;

    private String password;

    private String photo;

    private Date createtime;

    private Date updatetime;

    private String signature;

    private Date lastlogin;

    private Integer rank;

    //用户关注对象
    public List fllower;

    public List getFllower() {
        return fllower;
    }

    public void setFllower(List fllower) {
        this.fllower = fllower;
    }

   
}
