spring mvc: multi-action controller (methods that implement multiple accesses under the Controller)

For example, my controller is UserController.java, and there are multiple methods such as home, add, remove, etc.

address:

http://localhost:8080/projectname/user/add.html

http://localhost:8080/projectname/user/home.html

http://localhost:8080/projectname/user/remove.html

 

The class you need to use: org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

In the configuration file:

org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping

　　

In the code class:

org.springframework.web.servlet.mvc.multiaction.MultiActionController;

　　

 

Currently there are three configuration files: applicationContext.xml, springmvc-servlet.xml, web.xml

Specifically look at the code:

web.xml

<web-app>
  <display-name>Archetype Created Web Application</display-name>  
  
  <!--Configuration file path-->
<context-param>
 	<param-name>contextConfigLocation</param-name>
	<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<!-- character filter -->  
<filter>
   <filter-name>encodingFilter</filter-name>
   <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
   <init-param>
       <param-name>encoding</param-name>
       <param-value>UTF-8</param-value>
   </init-param>  
</filter>  
<filter-mapping>  
    <filter-name>encodingFilter</filter-name>  
    <url-pattern>/*</url-pattern>  
</filter-mapping>

<!-- Monitor forwarding-->
<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
  <servlet>  
    <servlet-name>springmvc</servlet-name>  
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
<servlet-mapping>  
    <servlet-name>springmvc</servlet-name>  
    <url-pattern>/</url-pattern>  
</servlet-mapping>    
  
  
</web-app>

UserController.java

public class UserController extends MultiActionController {

	
	public ModelAndView home(HttpServletRequest request, HttpServletResponse response) {
		ModelAndView mv = new ModelAndView("user_home");
		mv.addObject("message", "home");
		return mv;
		
	}

}

　　

The jsp code is basically the same:

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<%@ page isELIgnored="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>home</title>
</head>
<body>


${message}

</body>
