springMVC学习总结(一) --springMVC搭建

搭建项目

  1.创建一个web项目,并在项目中的src文件夹下创建一个包com.myl.controller.

  2.添加相应jar包

  3.在com.myl.controller包下创建一个Java类InderController

  4.在/WEB-INF文件夹下创建Spring配置文件web.xml和springmvc-servler.xml

创建完成后,整个工程的目录结构如下图所示 

 

 IndexController.java

package com.myl.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * 
 * @author myl
 * @date      2018年5月19日   上午9:35:33
 */

@Controller
public class InderController {
    
    @RequestMapping("/index")
    public String index(ModelMap model) {
        model.addAttribute("message", "Hello Spring MVC");
        return "index";
    }

}

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
   xmlns="http://java.sun.com/xml/ns/j2ee" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>springMVC Application</display-name>

    <servlet>
        <!-- 如果不配做<init-param><init-param>的话
        配置文件是默认的 servlet-name + servlet.xml
        例如我的servlet-name 是springmvc  默认配置文件就必须是springmvc-servlet.xml
        servlet-name名称必须和springmvc-servlet.xml对应 -->
        <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>

 

springmvc-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:mvc="http://www.springframework.org/schema/mvc" 
   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-3.0.xsd
   http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

    <context:component-scan base-package="com.myl"></context:component-scan>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
   
</beans>

index.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!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>Insert title here</title>
</head>
<body>
    <div>
        我的第一个页面 jsp下面 ${message }
    </div>
</body>
</html>

 

需要jar包

  • servlet-api-x.y.z.jar
  • commons-logging-x.y.z.jar
  • spring-aop-x.y.z.jar
  • spring-beans-x.y.z.jar
  • spring-context-x.y.z.jar
  • spring-core-x.y.z.jar
  • spring-expression-x.y.z.jar
  • spring-webmvc-x.y.z.jar
  • spring-web-x.y.z.jar

运行结果
