maven由于它的的约定大于配置，可能会遇到我们写的配置文件无法被导出或者生效的问题
解决方案：
<!--在build中配置resources，来防止我们资源导出失败的问题--> <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>
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
