上面是错误信息，就是说UserMapper.java和UserMapper.xml不匹配，查了几个小时的资料，各种方法都试了，感觉最好的一篇是下面这一篇，各位可以看一下：

不过这也没有解决我的问题，不管怎么查看，包名，类名，方法名，方法参数类型，所有的东西都配置对了，还是报错，后来我又在resources下建了一个包，结果出现了下面这种情况：
发现com.rao.mapper和com.rao.pojo居然没有合在一起，说明这两个包的前两级目录没有重合，然后我就到项目的目录下区看，发现包的名称如下图所示：
com.rao.pojo居然成了1个包，不是3个包！！！！！！！！！！！！！
以前在IDEA里面建包时，直接创建com.rao.pojo是被创建成三个包的：com rao pojo，结果这里就成了一个包，叫做 ：com.rao.pojo
这样建立包结构java和xml肯定不会匹配，后来把包分步建立，就成功了，不报错了，这里真的巨坑！！！！！！！！
