今天在写一个项目，我使用spring来实现用户登录操作，应该调用的是ManagerMapper.xml中 id为managerLogin的SQL语句，我也在Biz层中输出了传递到后台的值与调用相关XML中的地址（红体字是我测试输出的数据），它是应该去找ManagerMapper.xml但是一直报错是TemplateMapper.map。网上也找了好多答案，一直没有解决，目光一直放在ManagerMapper.xml中，后来仔细检查了TemplateMapper.xml，才发现这个XML中有问题，所以在页面中我进行登录操作这里才报错，之前写好的一些正常功能再去测试也全部都报一样的错误，因为有干扰，以为是相关功能写错了，其实只是新增的这个xml文件出了问题。
测试输出结果：
{wcxmname=jjf, wcxmpwd=0425}
com.wcx.mapper.ManagerMapper.managerLogin报错提示：

修改之前：
<update id="updateTemplate" parameterMap="Map">
update wenchaxingtemplate set wcxtname=#{wcxtname} where wcxtid=#{wcxtid};
</update>
<select id="temfindByPage" parameterType="Map" resultType="Template">select * from (select a.*,rownum rn from(select wcxtid,wcxtname from wenchaxingtemplate where status!=0) a
where rownum<=#{pageNo}*#{pageSize}) where rn>(#{pageNo}-1)*#{pageSize}
</select>
修改之后：
<update id="updateTemplate" parameterType="Map">
update wenchaxingtemplate set wcxtname=#{wcxtname} where wcxtid=#{wcxtid};
</update>
<select id="temfindByPage" parameterType="Map" resultType="Template">
select * from (select a.*,rownum rn from(select wcxtid,wcxtname from wenchaxingtemplate where status!=0) a
where rownum<=#{pageNo}*#{pageSize}) where rn>(#{pageNo}-1)*#{pageSize}
</select>
查看Mybatis官方的资料，SQL映射的XML文件已经废弃了parameterMap，现在都是用parameterType来进行相关的操作！！！
这就解决了 Parameter Maps collection does not contain value for com.wcx.mapper.*.Map 这个问题，所以之前测试好的功能后来发现也执行不了，那就应该就是哪个xml文件有错误，还是要相信自己，血的教训，就这个问题看了两天，浪费了好多时间，以后一定会记得了。
