mybatis实现数据库批量插入两种方式

一、一次插入多个对象

  <insert id="addList">
        insert into user
        (name,age,mobilephone,sex,birthday,email) values
        <foreach collection="contactInfos" item="item" open="(" close=")" separator="),(">
            #{item.name,jdbcType=VARCHAR},
            #{item.age,jdbcType=INTEGER},
            #{item.mobilephone,jdbcType=VARCHAR},
            #{item.sex,jdbcType=INTEGER},
            #{item.birthday,jdbcType=TIMESTAMP},
            #{item.email,jdbcType=VARCHAR}
        </foreach>
    </insert>
二、一次插入一个map集合,value为List

  String uid = "aaa";
  List<String> phoneList;
  List<String> emailList;
  List<Map> mapList = new ArrayList<>();
  for (int i=0; i<phoneList.size(); i++) {
    Map map = new HashMap();
    map.put("phone",phoneList.get(i));
    map.put("email",emailList.get(i));
    mapList.add(map);
  }
  contactMapper.addList(uid, mapList);
  <insert id="addList">
        insert into contact values
        <foreach collection="contactMapList" item="map" index="index" close=";" separator=",">
            (#{uid},
            #{map.phone},
            #{map.email})
        </foreach>
      </insert>
