我正在使用jersey编写简单的Java后端，我想将它部署到运行Debian的虚拟服务器上。我想，我已<Router routes={routes} history={browserHistory}/>
与tomcat7一起正确安装，并且还正确设置了用户角色（tomcat7-admin和manager-gui）。
当我访问manager-script时，我可以看到tomcat在运行。我也可以通过http://my-ip-address:8080访问管理器，所以我认为tomcat配置正确。
问题在于，当我想部署我的Web应用程序时（使用http://my-ip-address:8080/manager/html），部署本身并不起作用。这是来自maven的痕迹：
tomcat7-maven-plugin以下是有关该事物的卡塔琳娜日志的内容：
[INFO] tomcatManager status code:200, ReasonPhrase:OK

我不知道上面的错误意味着什么，因为我能够使用idea（而不是maven-tomcat-plugin）将此应用程序部署到我的本地tomcat。我会尝试提供所需数量的信息，因为我需要相当快速地解决这个问题。
我阅读了一些关于类似失败的线索，解决方法是将Aug 28, 2016 11:49:29 AM org.apache.catalina.util.LifecycleBase stop

的范围设置为javax.servlet-api。在我的provided我没有这种依赖关系，因为pom.xml已经提供了它，所以我对如何解决这个问题没有其他想法。
这是我真正的pom：
jersey-servlet你有任何想法，我该如何解决这个问题？
