Spring MVC not initial request mapping - spring

Question

Does the web deploy mechanism affect Spring MVC work?
I create a web project(SpringMVCTest) contains web.xml and a pjsp pages then I create a Java project(SpringMVCTestSrc) and use the link source function to link test_src and SpringMVCTestSrc.
My Eclipse workspace
My problem is if I deploy the project in war file then it works fine
, EX: if I open
localhost:8080/SpringMVCTest/message/showMessage.pages
it will forward to
main/showMessage.jsp
but if I deploy the project with separate web and jar file it will no request mapping found like below.
[DEBUG]-[2015/07/30 15:03:39,o.s.w.s.DispatcherServlet(init):139]: Servlet 'dispatcher' configured successfully
[DEBUG]-[2015/07/30 15:03:40,o.s.w.s.DispatcherServlet(doService):861]: DispatcherServlet with name 'dispatcher' processing GET request for [/SpringMVCTest/message/showMessage.pages]
[DEBUG]-[2015/07/30 15:03:40,o.s.w.s.m.m.a.RequestMappingHandlerMapping(getHandlerInternal):294]: Looking up handler method for path /message/showMessage.pages
[DEBUG]-[2015/07/30 15:03:40,o.s.w.s.m.m.a.RequestMappingHandlerMapping(getHandlerInternal):302]: Did not find handler method for [/message/showMessage.pages]

The log shows the different.
If I deploy in war file. The log shows found 18 bean definitions and request mapping works fine.
Export war file from Eclipse and put it to apache-tomcat-8.0.21\webapps
Startup Tomcat and open localhost:8080/SpringMVCTest/message/showMessage.pages
The page will show Message : Hello world

If I deploy with separate web and jar file. The log shows found 17 bean definitions and request mapping does not work.
Build a directory in apache-tomcat-8.0.21\webapps, EX: apache-tomcat-8.0.21\webapps\SpringMVCTest
Copy WEB-INF, META-INF from Eclipse workspace to apache-tomcat-8.0.21\webapps\SpringMVCTest
Export jar file from SpringMVCTestSrc and put it to apache-tomcat-8.0.21\webapps\SpringMVCTest\WEB-INF\lib
Startup Tomcat and open localhost:8080/SpringMVCTest/message/showMessage.pages
The page shows HTTP 404

Does someone know why the same code but different deploy mechanism has different result?

Answer 1

I found what the problem is....
Root cause founded from Spring MVC document.
It means annotation scan need directory entries!!
The problem is if I export whole project into war file. It contains the complete directory entries in WEB-INF/classes directory but jar file has no directory entry information.
Resolve this problem just check the "Add directory entries" option in Eclipse export function.
