Default-servlet-handler and Annotation-driven configuration for Spring MVC

Using spring typically configures Url-pattern AS/, instead of a Web server servlet becomes the default servlet, static resources are inaccessible, add <MVC: Default-servlet-handler/> The servlet for the specified Web server is the default servlet, and the static resources are accessible. Access to the @RequestMapping("/model") was not accessible at that time.

The reason is: when < /> , the framework registers annotaitonmethodhandleradapter This bean, can handle ; configure <mvc:default-servlet-handler/> , the framework registered Handleradapter cannot process @RequestMapping , the controller cannot be found. There are several solutions to the solution:

One, add <MVC:ANNOTATION-DRIVEN/> configuration, after you add this configuration, The framework automatically registers requestma Span style= "Color:rgb (57,51,255); Font-family:monaco;" >ppinghandlermapping and (spring3.1 later version), you can process @RequestMapping .

Two, do not use @requestmapping, directly specify the control class, manual <   = "/hello"   = "Com.niuwolfs.controller.HelloController " /> Registration

Public class Hellocontroller implements controller{

@Override

Public Modelandview HandleRequest (httpservletrequest req, HttpServletResponse resp) throws Exception {

Modelandview mv = new modelandview ();

MV . AddObject ("msg", "Hello Spring mvc!" );

mv. Setviewname ("Hello");

return mv;

}

}

Iii. Manual registration of requestmappinghandlermapping and requestmappinghandleradapter

<!--Spring3.1 After using this type of configuration handler Mapping-

< Bean class=" Org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping "/>

<!--Spring3.1 After using this type of configuration handler Adapter-

< Bean class=" Org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter "/>

Four, do not configure the <mvc:default-servlet-handler/>, the spring Url-pattern configured as. Do, will not replace the Web service's default servlet, However, access to the controller must be matched with the configured. Do and so on.
