出现该异常的原因是因为我们在写springboot项目时，一般将*Mapper.xml文件放入resouces文件夹下，而我们在导入非springboot项目或者说我们导入的项目中，Mapper.xml文件不在resouces文件夹下。这时候我们运行该项目就会出现该异常。为啥会这么说呢？这时候我们不难发现，在编译后生成的target文件夹下，并没有将Mapper.xml文件进行编译，这才是问题产生的根本原因。
所以出现这种请框，不要慌张。只要将上 面build标签中的代码放入pom.xml文件中即可。这时候，再看target文件，里面就会有*Mapper.xml文件，该问题就会得到解决。
下面就是我的pom.xml中的全部内容，我将需要插入的代码放在了pom.xml中的最下面。该方法仅供参考，如有疑问或错误，请大家及时发表意见，我会虚心采纳。
