mybatis的mapper.xml编写
最近在使用mybatis进行项目开发，关于mapper.xml进行如下总结，希望对跟我一样的初学者有一些帮助：
一、resultMap的编写，该类型最大的用处就是用于定义查询返回的类型，代码如下所示：
resultMap标签中的type属性为整个实体对应文件，若该实体包含对象类型属性则使用association标签；若包含list属性则使用collection标签。collection中属性过多，可以使用例子中的查询方式。
二、编写查询方法，动态拼接查询条件，入参类型为map，查询结果以上面定义的resultMap形式展现：
and BAZ463=#{id}
and BAZ002=#{baz002}
and AAB299=#{tgtAgencyState}
and AAE270=#{contactNoteNumber}
and AAE405=#{transBillNumber}
and BAC999=#{formerPersonNumber}
and AAE035=#{transferDate}
and AIC113=#{pensionInsTransDirection}
and AAE173=#{transferType}
and AAB004=#{srcUnitName}
and AAB305=#{firstJoinlandPersonalPaytime}
and AAC049=#{firstPersonalPaytime}
and AAC032=#{personActCreateTime}
and AAE030=#{paymentBeginTime}
and AAE031=#{paymentEndTime}
and AAE201=#{actualPaymentMonths}
and AIC093=#{oldPersonalActSum}
and AIC089=#{theNewPersonalActSum}
and AIC082=#{transYearInPersonalAct}
and AIC083=#{personalActTransSum}
and AIC084=#{regionFundTransferSum}
and AIC102=#{transferFundSum}
and BAE787=#{repeatFees}
and BAE829=#{repeatFeeFlag}
and BAE828=#{giveupAddFee}
and AAD019=#{fundTransferBankNumber}
and AAB300=#{transferInAgencyName}
and AAA146=#{transferOutAgencyName}
and AAZ198=#{nationAgencyId}
and BAE062=#{transEventId}
and BAE037=#{onlineDownload}
and BAE038=#{isConfirm}
and BAE022=#{uploadStatus}
and BZE111=#{uploadOperator}
and BZE136=#{uploadOperateTime}
and AAE013=#{remark}
and BAE681=#{transBeforeEventId}
and AAC067=#{contactPhone}
and BAE039=#{financeStatus}
and AAE011=#{aae011}
and AAE036=#{aae036}
and AAB034=#{aab034}
and AAA027=#{aaa027}
and BZE011=#{bze011}
and BZE036=#{bze036}
and BZE034=#{bze034}
and AAZ341=#{sysTraceId}
and AAB301=#{srcAgencyState}
and AAC001=#{personId}
and AAC999=#{personNumber}
and AAC002=#{socialEnsureNumber}
and AAC003=#{name}
and AAC004=#{sex}
and AAC006=#{birthday}
and AAC028=#{migrantWorkers}
and AAC010=#{householdAddress}
and AAE473=#{transferAccountType}
and AAC007=#{workDate}
三、编写更新方法，动态进行value补充，入参类型为实体型：
UPDATE test
BAZ002=#{baz002},
AAB299=#{tgtAgencyState},
AAE270=#{contactNoteNumber},
AAE405=#{transBillNumber},
BAC999=#{formerPersonNumber},
AAE035=#{transferDate},
AIC113=#{pensionInsTransDirection},
AAE173=#{transferType},
AAB004=#{srcUnitName},
AAB305=#{firstJoinlandPersonalPaytime},
AAC049=#{firstPersonalPaytime},
AAC032=#{personActCreateTime},
AAE030=#{paymentBeginTime},
AAE031=#{paymentEndTime},
AAE201=#{actualPaymentMonths},
AIC093=#{oldPersonalActSum},
AIC089=#{theNewPersonalActSum},
AIC082=#{transYearInPersonalAct},
AIC083=#{personalActTransSum},
AIC084=#{regionFundTransferSum},
AIC102=#{transferFundSum},
BAE787=#{repeatFees},
BAE829=#{repeatFeeFlag},
BAE828=#{giveupAddFee},
AAD019=#{fundTransferBankNumber},
AAB300=#{transferInAgencyName},
AAA146=#{transferOutAgencyName},
AAZ198=#{nationAgencyId},
BAE062=#{transEventId},
BAE037=#{onlineDownload},
BAE038=#{isConfirm},
BAE022=#{uploadStatus},
BZE111=#{uploadOperator},
BZE136=#{uploadOperateTime},
AAE013=#{remark},
BAE681=#{transBeforeEventId},
AAC067=#{contactPhone},
BAE039=#{financeStatus},
AAE011=#{aae011},
AAE036=#{aae036},
AAB034=#{aab034},
AAA027=#{aaa027},
BZE011=#{bze011},
BZE036=#{bze036},
BZE034=#{bze034},
AAZ341=#{sysTraceId},
AAB301=#{srcAgencyState},
AAC001=#{personId},
AAC999=#{personNumber},
AAC002=#{socialEnsureNumber},
AAC003=#{name},
AAC004=#{sex},
AAC006=#{birthday},
AAC028=#{migrantWorkers},
AAC010=#{householdAddress},
AAE473=#{transferAccountType},
AAC007=#{workDate},
WHERE BAZ463=#{id}
四、编写保存方法，入参类型为实体型：
insert into test
