我想为我的Java程序找到一个简单的http服务，经过研究后，我发现nanohttpd如此轻巧，它只有一个Java页面，并且易于安装，因此我想用这个框架包装Java程序。
我已经在nanohttpd github页面上尝试了教程，一切正常，但是对于最后一步，
mvn exec:java -Dexec.mainClass="com.example.App"
此信息大约15秒后崩溃了
[root@zhangruichang-test-dev001-shgq myHellopApp]# mvn exec:java -
Dexec.mainClass="com.example.App"

目前，我已经在Google上进行了搜索，但是没有任何最相关的问题。
我用
Apache Maven 3.0.5（r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 21：51：28 + 0800）和OpenJDK具有
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”，拱门：“ amd64”，家族：“ unix”
使用CentOS 6.4。
有人可以帮我吗？
最佳答案
可能是一个提示：您可以更改“ exec-maven-plugin”以告诉它不要杀死守护程序线程。
如：
<configuration>
<mainClass>com.test.Startup</mainClass>
<cleanupDaemonThreads>false</cleanupDaemonThreads>
</configuration>
