idea不像eclipse那样自动将新保存的文件或目录及其他资源更新到target目录中，必须在pom.xml中设置
<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.*</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.*</include> </includes> </resource> </resources> </build>
这样maven clean 就可以了！
