尼瑪,被mybatis的*Mapper.xml文件害慘了！整整兩天都在圍繞這個(gè)問題轉(zhuǎn)圈！

先看問題長啥樣吧！下面是通過逆向工程生成的Mapper.xml文件，包路徑什么的都沒有錯(cuò)！

貼出來詳細(xì)的報(bào)錯(cuò)信息：

折騰了兩天，偶爾在網(wǎng)上見網(wǎng)友如下解決方案，才算是解決了（想大哭一場）：

在pom文件中添加如下配置，就可以將mapper文件也一并編譯打包。

<!-- 如果不添加此節(jié)點(diǎn)mybatis的mapper.xml文件都會被漏掉。 --><build><resources><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>false</filtering></resource></resources></build>
