mybatis加数据库表

1. 在数据库中填加新表
2. 在总配置文件中加入子mapper地址

3. <?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="com.nuanshui.heatedloan.credit.dal.mapper.CreditChangeLogMapper" >//注意此处一定要与添加的类一致
       <resultMap id="creditChangeLogInfo" type="com.nuanshui.heatedloan.credit.model.CreditChangeLogInfo" >//注此处model也要与定义处一致
           <id column="id" property="id" typeHandler="idHandler" />
           <result column="user_id" property="userId"  />
           <result column="order_id" property="orderId"/>
           <result column="type" property="type"/>
           <result column="original_credit" property="originalCredit"/>
           <result column="new_credit" property="newCredit"/>
           <result column="log" property="log"/>
           <result column="created_at" property="createdAt" jdbcType="TIMESTAMP" />
           <result column="updated_at" property="updatedAt" jdbcType="TIMESTAMP" />
       </resultMap>
       <insert id="batchInsertCreditChangeLogList"  parameterType="java.util.List">
           <selectKey resultType="long" keyProperty="idRaw" >
               SELECT LAST_INSERT_ID() AS id
           </selectKey>
           insert into credit_change_log (user_id, order_id, type, original_credit, new_credit, log, created_at, updated_at) values
           <foreach collection="list" item="item" index="index" separator=",">
               (#{item.userId},#{item.orderId},#{item.type},#{item.originalCredit},#{item.newCredit},
               #{item.log},now(),now())
           </foreach>
       </insert>
   </mapper>
