Maven项目在编译后，src下的一些静态资源，如：xml、properties等可能不会被build。导致生成的目标文件target中没有这些静态资源，引发错误。

出现此问题时，需要在maven的pom.xml中对其进行如下配置:

    <build>
        <resources>

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

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

        </resources>
    </build>
