其他

生成后的插入sql写法是这样的

<insert id="insert" parameterType="com.clouddisk.model.PFileIndex">
    <!--
      WARNING - @mbg.generated
      This element is automatically generated by MyBatis Generator, do not modify.
    -->
    <selectKey keyProperty="pIndexId" order="AFTER" resultType="java.lang.Long">
      SELECT LAST_INSERT_ID()
    </selectKey>
    insert into p_file_index (file_size, create_time, p_name, 
      p_path, file_md5)
    values (#{fileSize,jdbcType=BIGINT}, #{createTime,jdbcType=TIMESTAMP}, #{pName,jdbcType=VARBINARY}, 
      #{pPath,jdbcType=VARBINARY}, #{fileMd5,jdbcType=VARBINARY})
  </insert>
