Mybatis的批量插入总结_mybatis批量新增并且判断空

1、批量插入

<insert id="insert" parameterType = "java.util.List">
    insert into stu(id,name)
    values
    <foreach collection="list" item = "item" separator =",">
        (#{item.id},#{item.name})
    </foreach>
</insert>

2、判空插入

<insert id = "insert" parameterType="Map">
    insert into stu
    <trim prefix = "(" suffix = ")" suffixOverrides = ",">
        <if test="id !=null and id !=''">id,</if>
        <if test="name !=null and name !=''">name,</if>
        create_time
    </trim>
    <trim prefix = "values(" suffix = ")" suffixOverrides=",">
          <if test="id !=null and id !=''">#{id},</if>
          <if test="name !=null and name !=''">#{name},</if>
           sysdate()
    </trim>
 
</insert>

小技巧：在mybatis中生成插入时间可以用sysdate()函数
