mybatis批量删除

批量删除所选择的用户

  <!-- 批量删除所选择的用户 -->
  <delete id="deleteSomeUser" parameterType="int">
      delete from user where id in
      <foreach collection="array" item="user_id" open="(" separator="," close=")">
          #{user_id}
      </foreach>
  </delete>

　　这里collection:表示类型,这里参数是数组,就写成array,如果是集合,就写成list

UserMapper.java里

写的是：

//批量删除用户
void deleteSomeUser(Integer[] user_id);
