datetime类型的处理

以处理错误日志为例：

<? xml   version =   "1.0"   encoding   = "UTF-8"   ?>

<! DOCTYPE   mapper   PUBLIC   "-//mybatis.org//DTD Mapper 3.0//EN"   "http://mybatis.org/dtd/mybatis-3-mapper.dtd"   >

< mapper   namespace = "core.dao.StatErrorDao"   >

          < insert   id =   "batchSaveStatErrorHourly"   >

              insert into stat_error (err_date, cid, err_id, osid , versionid, deviceid, num ,                                       update_time)

              values

                 < foreach   collection = "list"   item = "item"   index =   "index"

                        separator = ","   >

                     (#{item.errDate,jdbcType=DATE}, #{item.cid}, #{item.errId},

                      #{item.osid}, #{item.versionid}, #{item.deviceid},  #{item.num},

                      #{item.updateTime, jdbcType=TIMESTAMP,javaType=java.sql.Timestamp})

                 </ foreach >

          </ insert >

</ mapper >

 

 

注释：mysql中的datetime类型字段，使用java.sql.Timestamp 类型  

           #{item.updateTime, jdbcType=TIMESTAMP,javaType=java.sql.Timestamp}

    

      date类型处理办法如下：

          #{item.errDate,jdbcType=DATE}
