无法与从同一Maven原型创建了两个web应用用SpringMVC启动Tomcat服务器(Unabl

我创建了使用弹簧MVC-快速入门 - 原型（包括Spring MVC的，春天的安全性，休眠），我可以运行各该应用程序的seperately Tomcat上，但不能在一起的两个Spring MVC应用。

当我到Tomcat添加两个项目，服务器将不会川方，我得到

Aug 30, 2013 8:14:48 PM org.apache.catalina.core.ApplicationContext log
INFO: Initializing Spring FrameworkServlet 'appServlet'

再下一行是错误的红色文字下方，然后服务器被终止

Exception in thread "main"

我启用了春天日志级别为DEBUG的logback.xml，它写了一堆日志消息与DEBUG和INFO，但没有与WARN或错误显示任何见识到了什么是内部发生的事情。

是否有任何身体来翻过这一点，并找到了解决办法？

添加日志的建议

Answer 1:

Venkat，

你需要为每个应用程序不同的根密钥。

如果您使用XML配置，然后使用Karthikenyan的做法，在每个web.xml中指定不同的值：

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>thisisdistinctforeachwebapp</param-value>
</context-param>

如果您使用的是免费的XML配置（实现WebApplicationInitializer），这是作为一个行一样简单：

servletContext.setInitParameter("webAppRootKey", "thisisdistinctforeachwebapp");

HTH

Answer 2:

挣扎了一段时间这个问题终于得到解决后，我写的是从我的工作，希望这将有助于其他处于类似的情况。

而具有的logback experimenteing，XML已经给实际错误的详细信息

SEVERE: A child container failed during start
java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: PermGen space

看起来像web应用程序是沉重与休眠，春季和其他库是有一个PermGen的空间的问题，所以我说的VM参数服务器如下
