本文详细介绍了如何使用Spring MVC框架进行简易部署，包括导入Jar包、配置web.xml、定义springmvc.xml、创建控制器及视图文件等步骤。特别强调了web.xml中servlet-mapping的url-pattern设置为/而非/*的重要性。

一.导入Jar包

二. 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">
  <!-- 项目名 -->
  <display-name>springmvc01</display-name>
  
  <!-- 欢迎页  -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  
  <!-- 配置 DispatcherServlet -->
  <servlet>
    <servlet-name>springDispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

三.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: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.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">
		<mvc:annotation-driven></mvc:annotation-driven>
		<!-- 配置扫描 -->
		<context:component-scan base-package="com.lee.handler">
		</context:component-scan>
		<!-- 配置视图解析器 -->
		<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="/WEB-INF/view/"></property>
			<property name="suffix" value=".jsp"></property>
		</bean>
</beans>

四.控制器:(controller)

package com.lee.handler;

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

@Controller
public class HelloWorld {
	@RequestMapping(value="/helloworld")
	public String helloworld() {
		System.out.println("success");
		return "success";
	}
	public HelloWorld() {
		System.out.println("............................................................................................");
	}
}

五.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>
	<a href="helloworld">HelloWorld</a>
</body>
</html>

六.success.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>
	SUCCESS
</body>
</html>

总结:

1.web.xml 中servlet-mapping中的url-pattern注意不是/*,是/

2.在uril中不能使用:号.

note:在controller中使用构造器可以通过启动日志检测容器是否能够扫描到控制器.

新手简单总结,欢迎大神指正.多谢!
