springmvc 框架搭建步驟：
1. 創建工程，拷貝springmvc相關的jar，並把jar拷貝到lib
可以去spring官網下載：https://spring.io/
2. 配置web.xml,配置前段控制器DispatcherServlet
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
3. 在web-inf 下創建springmvc配置文件，[servletname]-servlet.xml
文件名必須爲springmvc-servlet.xml
4. 配置HandlerMapping 根據benaname找到對應Conntroller（ 可以省略）
<bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping"></bean>
5. 創建JSP頁面，需要發出請求的頁面
<%@ 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>
<form action="hello.do" method="post">
hello:<input type="text" name="hello">
<input type="submit" value="提交">
</form>
</body>
</html>
6. 創建HelloController 繼承AbstractController重寫handleRequestInternal
package springmvc01;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
public class HelloController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {
String hello = request.getParameter("hello");
System.out.println("------"+hello);
ModelAndView mav = new ModelAndView("index");
mav.addObject("helloworld", hello);
return mav;
}
}
7.創建JSP頁面，需要發出請求的頁面
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>${helloworld}</h1>
</body>
</html>
8.在springmvc-sevlet.xml配置視圖解析器
<!-- 配置視圖解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前綴 -->
<property name="prefix" value="/view/"></property>
<!-- 後綴 -->
<property name="suffix" value=".jsp"></property>
</bean>
9. 在springmvc-sevlet.xml文件中配置Controller
<!-- 配置Controller -->
<bean name="/hello.do" class="springmvc01.HelloController"></bean>
9.運行效果
進入hello.jsp頁面，輸入點提交
顯示helloworld
以上輸入中文的話，有亂碼問題，下一篇會對亂碼的解決進行講解
