maven由于他的约定大于配置，我们之后可能遇到我们没写在resources目录中的配置文件无法导出或生效的问题，解决方案：
<!-- 在Build中配置resources 来防止除了resources目录中的配置文件之外的配置文件加载失败的问题--><build><resources><resource><directory>src/main/resources</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>true</filtering></resource><resource><directory>src/main/java</directory><includes><include>**/*.properties</include><include>**/*.xml</include></includes><filtering>true</filtering></resource></resources></build>
不过最好还是把资源文件放在resources文件夹中
