原因是使用IDEA的Maven构建项目时IDEA是不会编译src的java目录的xml文件

解决方案1：

不将xml放到src目录下面，将xxx.xml放到Maven构建的resource目录下面！

解决方案2：

在Maven的pom文件中，添加下面代码：

<build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
</build>
