Mybatis中Dao层

public interface UsersMapper {
    public void insertEntitys(List<UserEntity> users);
}

Oracle中批量插入

<insert id="insertEntitys" parameterType="list" useGeneratedKeys="false">
  INSERT INTO tab_user(id,name)
    select cd.* from(
    <foreach collection="list" item="item" index="index"  close=")" open="(" separator="union">
        select
       #{item.id,jdbcType=VARCHAR},
       #{item.name,jdbcType=VARCHAR}
        from dual
    </foreach>
    ) cd
</insert>

Mysql中批量插入

<insert id="insertEntitys" parameterType="list"> 
    insert into tab_user(id,name) values  
    <foreach collection="list"item="item" index="index"separator="," >  
       (
          #{item.id,jdbcType=VARCHAR},      
          #{item.name,jdbcType=VARCHAR}
        )
