Integrated springmvc

Build a controller of the package, write a TestController.java

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("con")
public class TestController {

    public TestController(){
        System.out.println("123123123");
    }
    
    @RequestMapping("test")
    @ResponseBody
    public String testmvc(){
        System.out.println("testmvc");
        return "testmvc";
    }
    
}

Write constructors convenient scanning to see if

 

springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd ">  <-! Configuration Controller Scan ->
    
    <context: Component Base-Package-Scan = "Controller" />
 <-! drive configuration annotation ->  <MVC: Annotation-Driven /> 
 <-! configuration view resolver -> ! <- <the bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver"> prefix <property name = "prefix" value = "/ WEB-INF / jsp /" /> suffix <property name = "suffix" value = ". jsp "/> </ the bean> -> </ Beans>

springmvc.xml need to be configured to scan the packet controller, prefixes and suffixes in the jump action is jsp prefix and suffix

 

Add springmvc configuration in the web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
