SPRINGMVC Framework Learning Note (3)--controller configuration Rollup

1. Corresponding Bean via URL

 <!--  Configure Handlermapper mapper  -->  <  bean  class  = " Org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping " />  <!--  Configure controller custom controllers  -->  <  bean  name  = "/hello.do"   class  =" Cn.sxt.controller.HelloController " />  

With the above configuration, access to hello.do accesses the bean with the ID hello.do, which is suitable for small systems.

If you add a handleradapter configuration, you do not need to.

<!---<class= " Org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter "/>

2. Assigning a bean to a URL

<Beanclass= "Org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">    < Propertyname= "Mappings">        <Props>            <propKey= "/hello.do">Hellocontroller</prop>        </Props>    </ Property></Bean><BeanID= "Hellocontroller"class= "Cn.sxt.controller.HelloController"></Bean>

This type of configuration can also use wildcards, and when accessing Hello.do, Spring assigns the request to the Hellocontroller processing

3.URL Matching Bean

<class= " Org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping "></Bean  ><!--<name= " Hellocontroller "  class=" Cn.sxt.controller.HelloController"></  Bean>

4. Annotations

<!-- the spring container scans all classes under the specified package, if there are annotations  on the class  - <  base-package= "Cn.sxt.controller"/>

//developing spring MVC with annotations//with this note, the spring container will create a Bean object based on the annotation. The object's ID is the class name (lowercase first letter)//<bean id= "Hellocontroller" class= "Cn.sxt.controller.HelloController"/>@Controller Public classHellocontroller {//you can specify that the requested URL is mapped to the method by using the @requestmapping annotation@RequestMapping (value= "/hi.do")     PublicModelandview Hello () {modelandview mv=NewModelandview (); Mv.setviewname ("Hello"); Mv.addobject ("MSG", "annotation------"); returnMV; }}
