Spring DispatcherServlet: No mapping found for HTTP request

问题:

I have an issue implementing a very simple page using spring mvc 3.2.4.RELEASE.

My controller looks like this:

@Transactional @Controller public class MembersDetailsController {     @Autowired     private MemberService memberService;      @RequestMapping(value = "/member/{name}", method = RequestMethod.GET)     public String displayMember(@PathVariable String name) {         System.out.println(name);         return "member";     }      @RequestMapping(value = "/member", method = RequestMethod.GET)     public String displayMember() {         System.out.println("Empty");         return "member";     } } 

When I call

http://127.0.0.1:8080/member 

the respective method is being executed as desired. However, wenn I call

http://127.0.0.1:8080/member/test 

or

http://127.0.0.1:8080/member/test/ 

I get a 404 with the log-output:

WARN  org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/member/test] in DispatcherServlet with name 'mvc-dispatcher' 

Whats really weired is the a previous log says:

INFO  org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/member/{name}],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String  INFO  org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/member],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String 

Which means that the mapping should be correct as far as I understand this.

This is my web.xml:

MitgliederdatenbankcontextConfigLocation/WEB-INF/spring-security.xml, /WEB-INF/applicationContext.xmlhibernateFilterorg.springframework.orm.hibernate3.support.OpenSessionInViewFiltersessionFactoryBeanNamehibernateSessionFactoryspringSecurityFilterChainorg.springframework.web.filter.DelegatingFilterProxyhibernateFilter/*springSecurityFilterChain/*org.springframework.web.context.ContextLoaderListenerspringGwtRemoteServiceServletorg.spring4gwt.server.SpringGwtRemoteServiceServletmvc-dispatcherorg.springframework.web.servlet.DispatcherServletcontextConfigLocation/WEB-INF/applicationContext.xml1springGwtRemoteServiceServlet/ui/springGwtServices/*mvc-dispatcher/welcomemvc-dispatcher/loginmvc-dispatcher/logoutmvc-dispatcher/loginfailedmvc-dispatcher/member/*/login

Could anybody please give me a hint what went wrong here?

I believe that the problem is the same one as described here URL Mapping issue - Spring web MVC .

Unless you use alwaysUseFullPath spring mvc will match * part to the mapping you specified (e.g. /member/member/test ). See docs for alwaysUseFullPath here (section 17.4) http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html .

However, unfortunately, this property is not exposed through xml configuration element (if you're using xml configuration) so if you'd like your mappings to work the way you discribed in your question you'll need to configure it as described here: http://blog.sarathonline.com/2013/07/enable-alwaysusefullpath-with.html

I was faced with the same problem and solved problem by using

This tag will configure two beans DefaultAnnotationHandlerMapping and AnnotationMethodHandlerAdapter.

Also I added tag to my dispatcher servlet config file.
