springMvc-框架搭建
搭建springmvc框架的步骤：
1.在web.xml中配置springMvc的servlet
2.创建controller处理页面传来的数据，
3.床架springMvc文件，处理视图：
3.1：配置对controller的扫描
3.2：配置逻辑视图对应的物理视图
4.创建jsp页面用于跳转到指定的controller
5.创建jsp页面用于对应springMvc的物理跳转视图
代码部分：
web.xml

</servlet>
<servlet-mapping>

</web-app>
controller
package com.java1234.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloWorldController {
@RequestMapping("/helloWorld")
public String helloWorld(Model model){
model.addAttribute("message", "StringMvc大爷你好！");
return "helloWorld";
}
}
springMvc部分
<?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:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
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.xsd">
<!-- 使用注解的包，包括子集 -->
<context:component-scan base-package="com.java1234"/>
<!-- 视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="http://www.mamicode.com/WEB-INF/jsp/" />
<property name="suffix" value="http://www.mamicode.com/.jsp"></property>
</bean>
</beans>
html跳转到controller
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<a href="http://www.mamicode.com/helloWorld.do">问候SpringMvc他大爷</a>
</body>
</html>
springMvc配置逻辑视图指向的物理视图：
<%@ 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>
${message }
</body>
</html>
