问题
I have a small Java/Spring MVC REST /Maven app that runs just fine in Eclipse but also when I run the following command from the prompt:
mvn clean tomcat6:run
My problem is when I do:
mvn clean package
and push the generated war file to the "webapps" folder in my standalone Tomcat instance, the service doesn't work anymore.
The standalone Tomcat starts up just fine, no error in the logs. Interestingly enough though the standalone instance listens on port 8989 vs. 8080 when I run the app in Eclipse or through the mvn command.
Once the app is up in the standalone Tomcat if I try to hit my service w/ RESTClient I get a 404 back. My custom 404 actually, not the generic one.
Also the static content, like my index.html comes up just fine.
Here is my web.xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>

Is there anything in that configuration that would explain why any request to the dispatcher servlet return 404 instead of routing to the controller?
Thanks

回答1:
If you merely copy yourproject.war to Tomcat's webapps folder and let the default deployer kick in (which expands yourproject.war to a directory named yourproject) then you should be aware that the default Tomcat logic is to make your app available under the context path (read: URL) of /yourproject.
If you want the app to be available under the root context (/) you should configure Tomcat appropriately.
回答2:
So this is your combination.
App - Environment Status
Eclipse->Working
Eclipse Embedded TOMCAT -> working
Standalone TOMCAT -> Not working
See the Eclipse Tomcat preferences, it might have added class path and library path which would make the Tomcat to identify. Faced similar problem in the past.
Also, your static content works fine. It implies that some important jar to run is present in eclipse classpath which is not visible in Standalone Tomcat.
Cheers

Figured it out. I had to change the servlet mapping in web.xml from this:
<servlet-mapping>
<servlet-name>skunk</servlet-name>
<url-pattern>/skunk/*</url-pattern>
</servlet-mapping>
to this:
<servlet-mapping>
<servlet-name>skunk</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
To be able to reach the service using the url:
http://localhost:8080/skunk/myService
The original mapping I had in there meant I would have had to type in:
http://localhost:8080/skunk/skunk/myService
to reach my service... sigh
Thank you guys!
