Spring mvc-Controller-Property Method name Resolver (properties methods name Resolver) example (reprint practice)

The following content is translated from: https://www.tutorialspoint.com/springmvc/springmvc_propertiesmethodnameresolver.htm

Description: The sample is based on spring MVC 4.1.6.

The following example shows how to use the Spring WEB MVC framework To use the property method name resolution method of a multi-action controller. The Multiactioncontroller class helps you map multiple URLs to their methods in a single controller, respectively.

<Beanclass= "Com.tutorialspoint.UserController">   < Propertyname= "Methodnameresolver">      <Beanclass= "Org.springframework.web.servlet.mvc.multiaction.PropertiesMethodNameResolver">         < Propertyname= "Mappings">            <Props>               <propKey= "/user/home.htm">Home</prop>               <propKey= "/user/add.htm">Add</prop>               <propKey= "/user/remove.htm">Update</prop>                  </Props>         </ Property>      </Bean>   </ Property></Bean>

For example, using the above configuration, if it is a URI

1. /user/home.htm is requested, dispatcherservlet forwards the request to the Usercontroller Home () method.

2. /user/add.htm is requested, dispatcherservlet forwards the request to the Usercontroller Add () method.

3. /user/remove.htm was requested, Dispatcherservlet forwarded the request to the UsercontrollerRemove () method.

First, let's use the Eclipse IDE and follow these steps to develop a dynamic form-based Web application using the Spring Web framework:

Steps	Description
1	Create a name for the project TestWeb package under Com.tutorialspoint as explained in the Spring Mvc-hello World Example Chapter.
2	Create a Java class Usercontroller under the Com.tutorialspoint package.
3	Create a view file under the JSP subfolder user.jsp.
4	The final step is to create the contents of all the source and configuration files and export the application as described below.

Usercontroller.java

user.jsp

<%@ Page ContentType="text/html; Charset=utf-8" %><HTML><Head><title>Hello World</title></Head><Body>   <H2>${message}</H2>  </Body></HTML>

After you finish creating the source files and profiles, export the application. Right-click the application and use the Export > WAR file option and save your testweb.war file in the Tomcat WebApps folder.

Now start your Tomcat server and make sure you can access other pages from the WebApps folder using a standard browser. Now try URL http://localhost:8080/TestWeb/user/add.htm, if everything in your spring Web application is fine, you should see the following results:
