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
