我想为我的Java程序找到一个轻量级的http服务，经过研究，我发现nanohttpd只有一个java页面，并且安装简单，所以我想用这个包装我的Java程序框架。
我在nanohttpd github页面上尝试了教程，一切正常，但是最后一步，
mvn exec:java -Dexec.mainClass="com.example.App"
使用此信息约15秒后崩溃
[root@zhangruichang-test-dev001-shgq myHellopApp]# mvn exec:java -
Dexec.mainClass="com.example.App"

目前我用谷歌搜索了它，但没有任何相关问题。
我用 Apache Maven 3.0.5（r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21:51:28 + 0800）和OpenJDK with Java版本：1.7.0_85，供应商：Oracle Corporation 上 操作系统名称：“linux”，版本：“2.6.32-573.1.1.el6.x86_64”，arch：“amd64”，系列：“unix” 使用CentOS 6.4。
有人可以帮助我吗？

也许是一个提示：你可以改变“exec-maven-plugin”来告诉它不要杀死守护进程线程。 例如：
<configuration>
<mainClass>com.test.Startup</mainClass>
<cleanupDaemonThreads>false</cleanupDaemonThreads>
</configuration>
