SPRINGMVC Annotation and optimization

1. Create a new Web project

2. Add jar

3. Rewrite Web. XML, note the name of Spring-servlet.xml

<?xml version= "1.0" encoding= "UTF-8"? ><web-app version= "3.0" xmlns= "Http://java.sun.com/xml/ns/javaee" Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http ://java.sun.com/xml/ns/javaee/web-app_3_0.xsd "> <display-name></display-name> < welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <servlet&  Gt <servlet-name>springMVC</servlet-name> <servlet-class> Org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param> <param-name> Contextconfiglocation</param-name> <param-value>classpath*:config/springannotation-servlet.xml</ param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <  Servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </wEb-app> 

4. Write Springannotation-servlet.xml

<?xml version= "1.0" encoding= "UTF-8"? ><beans xmlns= "Http://www.springframework.org/schema/beans" Xmlns:xs I= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:p= "http://www.springframework.org/schema/p" xmlns:context= "H Ttp://www.springframework.org/schema/context "xmlns:mvc=" Http://www.springframework.org/schema/mvc "Xsi:sche malocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/sche Ma/beans/spring-beans-3.0.xsd Http://www.springframework.org/schema/context Http://www.sprin                Gframework.org/schema/context/spring-context-3.0.xsd HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/MVC  Http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "> <!--Note Scan Package--<context:component-scan Base-package= "Com.tgb.web.controller.annotation"/> <!--opening annotations-<bean class= "Org.springframew Ork.web.servlet.mvc.annotation. Annotationmethodhandleradapter "></bean> <bean class=" Org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping "></bean> <!--static resource access- -<mvc:resources location= "/img/" mapping= "/img/**"/> <mvc:resources location= "/js/" mapping= "/js/**"/&    Gt <mvc:resources location= "/css/" mapping= "/css/**"/> <!--viewresolver View Resolver--<bean id= "vie Wresolver "class=" Org.springframework.web.servlet.view.InternalResourceViewResolver "> <property name=" Prefix "value="/web-inf/jsp/"/> <property name=" suffix "value=". jsp "/> </bean> &LT;/BEANS&G T

5. New package com.tgb.web.controller.annotation, new class Usercontroller.java

Note how annotations are annotated, class annotations, and method annotations

Package Com.tgb.web.controller.annotation;import Org.springframework.stereotype.controller;import Org.springframework.web.bind.annotation.requestmapping;import Org.springframework.web.bind.annotation.requestmethod;import org.springframework.web.servlet.modelandview;@ Controllerpublic class Usercontroller {@RequestMapping (value= "/user/adduser", method=requestmethod.get) public Modelandview AddUser () {String result = "This is AddUser---------"; return new Modelandview ("/annotation", "result", result); } @RequestMapping (value= "/user/deluser", method=requestmethod.get) public Modelandview Deluser () {String result = ' This is Deluser---------"; return new Modelandview ("/annotation "," result ", result); }}

6. Under Spring-servlet.xml settings, create a new annotation.jsp under/web-inf/jsp/

<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%><% @taglib prefix= "C" uri= "/HTTP/ Java.sun.com/jsp/jstl/core "%><! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" >
　
7. IE Side access:
Http://localhost:8080/springMVC3/user/addUser
Show Results:
