1、建立WEB项目Spring MVC
2、引入jar包:
commons-logging-1.1.1
spring-aop-4.2.5.RELEASE.jar
spring-beans-4.0.0.RELEASE.jar
spring-context-4.0.0.RELEASE.jar
spring-core-4.0.0.RELEASE.jar
spring-expression-4.0.0.RELEASE.jar
spring-web-4.0.0.RELEASE.jar
spring-webmvc-4.0.0.RELEASE.jar
3、配置web.xml文件,这里直接贴完整的web.xml文件,里面会有一些注释:
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_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>Spring MVC</display-name>
<servlet>
<!-- 引入Spring MVC核心过滤器 -->
<servlet-name>springDispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 初始化参数 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<!-- 启动时加载 -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springDispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
4、在src下创建springmvc.xml文件,同上,直接贴代码:
springmvc.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 配置自动扫描注解的包 -->
<context:component-scan base-package="com.watimer.springmvc"></context:component-scan>
<!-- 配置视图解析器 -->
<!--
视图解析器的作用为:当请求成功时,跳转到“视图解析器前缀+返回值+视图解析器后缀界面”
以此项目为例,则跳转到WEB-INF/views/success.jsp界面
-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
5、在SRC下建包,注意与springmvc.xml中配置的要相同,这里为com.watimer.springmvc,同时建立类Hello,贴代码:
Hello.java
package com.watimer.springmvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* @author 易讯.岳耀栎
*/
//扫描Controller
@Controller
public class Hello {
//@RequestMapping对应的是请求路径,会在下文中指出
@RequestMapping("/hello")
public String hello(){
System.out.println("hello world");
//请求成功后,根据上文配置的视图解析器,会跳转到success.jsp界面
return "success";
}
}
6、在WEB-INF目录下,建立views文件夹,同时在views文件夹内新建success.jsp,一会会贴出项目的截图:
7、在index添加请求超链接,点击时会打印输出hello world,同时跳转到success.jsp界面:
index.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">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<!-- 这里的请求,对应的是@RequestMapping("/hello"),如果不一致,则请求不到-->
<a href="hello">helloworld</a>
</body>
</html>
7、请求界面
8、点击后的界面
8、控制台的输出
到此,第一个项目就完成了,项目源码可供下载
