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!
