搭建Dynamic Web Project(动态web项目)的springmvc工程2

此篇为“创建Dynamic Web Projec工程，”搭建Dynamic Web Project(动态web项目)的springmvc工程1的续篇,“搭建springmvc框架web项目”：

注：开发工具，以及jar包下载，404访问处理，请到上篇或下链接！！！

下载分享%springmvc开发分享****，（提取码：2c4a）也可网上下载，适合自己的或最新版本使用。

404错误解决可以查看：springmvc下404解决

搭建完的目录：

注：此处，如果，只有spring的包，而没有”commons-pool-1.4.jar“和”commons-logging-1.1.1.jar“(版本不限)，会在启动tomcat的时候，出现，找不到日志类Not found class Log，或者线程池错误Thread
pool。

然后，本篇，具体springmvc备注细节，why？，可上网查看。

1：使用maven或者，自己导入项目springmvc支持包，可在分析找到

2：配置web.xml配置文件：

配置web.xml文件为：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://xmlns.jcp.org/xml/ns/javaee"
	xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
  <display-name>tsshare</display-name>

  <!-- 监听spring上下文容器 -->
  <listener>
  	<listener-class>
  			org.springframework.web.context.ContextLoaderListener
  	</listener-class>
  </listener>
  <!-- 加载spring的xml配置文件到spring的上下文容器中 -->
  <context-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath*:/springmvc*.xml</param-value>
  </context-param>

  <!-- 配置springmvc DispatcherServlet  -->
  <servlet>
  	<servlet-name>mvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>/WEB-INF/conf/springmvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 配置DispatcherServlet需要拦截的url -->
  <servlet-mapping>
  	<servlet-name>mvc</servlet-name>
  	<url-pattern>*.html</url-pattern>
  </servlet-mapping>

  <!-- 欢迎页 -->
  <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>
</web-app>

注：此处注意：<url-pattern>*.html</url-pattern>

3：配置springmvc的配置文件为：

<?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:tx="http://www.springframework.org/schema/tx"
	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-3.0.xsd
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx-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">
		<!-- springmvc配置 -->
		<!-- 通过component-scan让spring扫描package下的所有类,让spring的注解生效-->
		<context:component-scan base-package="com.tsxs"></context:component-scan>
		<!-- 配置springmvc的视图渲染器,让其前缀为:/ 后缀为: .jsp 将视图渲染到 /views/<method返回值>.jsp中 -->
		<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="prefix" value="/WEB-INF/views/"></property>
			<property name="suffix" value=".jsp"></property>
		</bean>
</beans>

4：配置jsp页面：路径在”/WEB-INF/views/“下：

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>
			欢迎页!
</body>
</html>

home.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>
	我为spring的主页!
</body>
</html>

home1.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>
	我为spring的主页~~~1!
</body>
</html>

:5：配置springmvc的控制层类，自动通过annotation扫描，此处为HomeController：

package com.tsxs.controllers;

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

@Controller
public class HomeController {
	/**
	 * 首页 返回至 /views/home.jsp页面
	 * */
	@RequestMapping("index")
	public String toHome(){
		System.out.println("let`s  go!");
		return "home";
	}

	@RequestMapping("index1")
	public ModelAndView toHome1(){
		//创建模型和视图,用于渲染页面.并指向要返回的页面为home1
		ModelAndView mv = new ModelAndView();
		System.out.println("let`s  go1!");
		mv.setViewName("home1");
		return mv;
	}

}

注：此处注意：import org.springframework.web.servlet.ModelAndView;
