Tomcat 7 hangs on Initializing Spring root WebApplicationContext
提问by Matt Crysler
I am trying to deploy a Spring web application to Tomcat 7.0.24 but it hangs upon startup with the last lines showing as
我正在尝试将 Spring Web 应用程序部署到 Tomcat 7.0.24，但它在启动时挂起，最后几行显示为

INFO: Initializing Spring root WebApplicationContext
I recently upgraded to Spring 4.0.2 and am using a customer WebApplicationInitializer via annotations. Before the upgrade I was using Spring 3 with pure XML config and it worked just fine. My web.xml file looks like this:
我最近升级到 Spring 4.0.2 并通过注释使用客户 WebApplicationInitializer。在升级之前，我使用带有纯 XML 配置的 Spring 3，它工作得很好。我的 web.xml 文件如下所示：

Here is my web application initializer:
这是我的 Web 应用程序初始值设定项：
public class MarketplaceWebAppInitializer implements WebApplicationInitializer
{
@Override
public void onStartup(ServletContext container)
{
// Instantiate a new web application context
XmlWebApplicationContext rootContext = new MarketplaceXmlWebApplicationContext(container);
// Add the various listeners
container.addListener(new ContextLoaderListener(rootContext));
container.addListener(new RequestContextListener());
// Set the locations of the configuration files
rootContext.setConfigLocations(
new String[]
{
"applicationContext.xml",
"config/api-beans.xml",
"config/hibernate-beans.xml",
"config/security-beans.xml",
"config/service-beans.xml",
"config/settings-beans.xml",
"config/utility-beans.xml",
"config/mvc/web-beans.xml",
"config/jmx-beans.xml",
"config/ws/ws-beans.xml"
}
);
// Add the dispatcher servlet
ServletRegistration.Dynamic mvc =
container.addServlet("mvc", new DispatcherServlet(rootContext));
mvc.setLoadOnStartup(1);
mvc.setInitParameter("dispatchOptionsRequest", "true");
mvc.addMapping("/api/*");
mvc.addMapping("/html/*");
// Add the web services servlet
ServletRegistration.Dynamic ws =
container.addServlet("ws", new MessageDispatcherServlet(rootContext));
ws.setLoadOnStartup(2);
ws.setInitParameter("transformWsdlLocations", "true");
ws.addMapping("/service/*");
// Add the spring security filter
FilterRegistration.Dynamic springSecurityFilter =
container.addFilter("springSecurityFilterChain",
new DelegatingFilterProxy("springSecurityFilterChain"));
springSecurityFilter.addMappingForUrlPatterns(null, true, "/j_spring_security_check");
springSecurityFilter.addMappingForUrlPatterns(null, true, "/j_spring_security_logout");
springSecurityFilter.addMappingForUrlPatterns(null, true, "/api/*");
springSecurityFilter.addMappingForUrlPatterns(null, true, "/html/*");
// Add the static content filter
FilterRegistration.Dynamic staticContentFilter =
container.addFilter("staticContentFilter", new StaticContentFilter());
staticContentFilter.addMappingForUrlPatterns(null, true, "/static/*");
staticContentFilter.addMappingForUrlPatterns(null, true, "/generated/*");
// Add the logger filter
FilterRegistration.Dynamic loggerFilter =
container.addFilter("loggerFilter", new LoggerFilter());
loggerFilter.addMappingForUrlPatterns(null, true, "/api/*");
loggerFilter.addMappingForUrlPatterns(null, true, "/html/*");
}
}
Is there anything obvious that I am missing? I've checked all the other questions/answers on this topic and didn't find a solution.
有什么明显的我失踪了吗？我已经检查了有关此主题的所有其他问题/答案，但没有找到解决方案。

Setting an answer for this so others know what helped me in this particular situation. Turning on Spring logging allowed me to see that a database connection was in a hung state. Resolving the database issue allowed my application to finish deployment.
为此设置一个答案，以便其他人知道在这种特殊情况下是什么帮助了我。打开 Spring 日志记录让我可以看到数据库连接处于挂起状态。解决数据库问题使我的应用程序能够完成部署。

Had been trying to figure out this for a while.
一直试图弄清楚这一点。
The console got stuck at INFO: Initializing Spring DispatcherServlet 'dispatcherServlet'
控制台卡在 INFO: Initializing Spring DispatcherServlet 'dispatcherServlet'
Turns out that that was the last message and the service had already started. I was accessing the service on the wrong port.
原来这是最后一条消息，服务已经启动。我在错误的端口上访问了该服务。
Also, logging was not configured. So no logs showed up after the default output from spring.
此外，未配置日志记录。所以在 spring 的默认输出之后没有出现日志。
