SPRINGMVC annotation Enabled

This article is my study of the network video SPRINGMVC writing process.

Thank you for announcing the video of your predecessors.

The following comments Springmvc several key steps, notes enable:

First you need to load the configuration file (assuming you use a custom path)

<?
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 "xmlns:web=" http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd "xsi: schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id= "Webapp_ ID "version=" 2.5 "> <display-name>springMVC1</display-name> <welcome-file-list> < Welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> < Welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> < Welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </ welcome-file-list> <!--SPRINGMVC Entrance Dispatcher--<servlet> <servlet-name>springmvc</  Servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--loadInto the configuration file path-<init-param> <param-name>contextConfigLocation</param-name> <param-value>  Classpath*:config/springannotation-servlet.xml</param-value> </init-param> <!--when to start A value greater than 0 indicates that the servlet is initialized when the container starts, the smaller the positive value the higher the priority-<load-on-startup>1</load-on-startup> </servlet> <!-- Intercept-<servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</ Url-pattern> </servlet-mapping></web-app>

Second, the configuration file. The most basic is to open annotations and load the scan package when spring starts

<?xml version= "1.0" encoding= "UTF-8"?
><beans xmlns= "Http://www.springframework.org/schema/beans" xmlns:context= "http://www.springframework.org/ Schema/context "xmlns:p=" http://www.springframework.org/schema/p "xmlns:mvc=" http://www.springframework.org/ Schema/mvc "xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance "xsi:schemalocation="/HTTP/ Www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http:/ /www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd htt P://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "><!-- Spring Boot Scan Package--<context:component-scan base-package= "Com.tgb.web.controller.annotation" > </context: component-scan> <!--opening annotations--><bean class= " Org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter "/><bean class=" Org.springframework.web.servlet.mvc.aNnotation. Defaultannotationhandlermapping "></bean><!--path controller--><bean name="/test/helloworld " class= "Com.tgb.web.controller.HelloWorldController"/><!--View Resolution--<bean id= "Viewresolver" class= " Org.springframework.web.servlet.view.InternalResourceViewResolver "> <property name=" prefix "value="/web-inf           /jsp "></property> <property name=" suffix "value=". jsp "></property> </bean> <!--static resource access (do not block access to things under this folder)--><mvc:resources location= "/img/" mapping= "/img/**"/> </beans>

Again, write the controller's Java code

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.post) public Modelandview AddUser () {String result = "AddUser"; return new Modelandview ("/annotation", "result", result);} @RequestMapping (value= "/user/deluser", method=requestmethod.get) public Modelandview Deluser () {String result = " Deluser "; return new Modelandview ("/annotation "," result ", result);} @RequestMapping (value= "/user/touser", method=requestmethod.get) public Modelandview Touser () {String result = "Touser" ; return new Modelandview ("/touser", "result", result);}}

Please note here that the use of @Controller.

The value in the @RequestMapping (value= "/user/adduser", Method=requestmethod.post) represents a jump path, which means that the method is called in which way

Finally, the front-end JSP interface

annotation.jsp

<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%><%string path = Request.getcontextpath () ; String basepath = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () +path+ "/";%> <! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" >
Touser.jsp interface
 
 
<%@ page language= "java" import= "java.util.*" pageencoding= "UTF-8"%><%string path = Request.getcontextpath () ; String basepath = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () +path+ "/";%> <! DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" >
