Spring2.5注解 折磨了我N久的Helloworld

                         就是一个Helloworld ，看项目名 忍不住了 唉  只因  <context:component-scan base-package="com.ds.web"/>

中  com.ds.web  -------------------------cn.ds.web      做人要小心 做男人更要小心

Spring MVC 第一个Helloworld  

首先 我们先把添加Spring2.5支持，配置Web.xml

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --> 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
 5     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
 6     <context-param>
 7         <param-name>contextConfigLocation</param-name>
 8         <param-value>
 9             /WEB-INF/hello-data.xml /WEB-INF/applicationContext.xml
10         </param-value>
11     </context-param>
12 
13     <!--  Spring 容器启动监听器 -->
14     <listener>
15         <listener-class>
16             org.springframework.web.context.ContextLoaderListener
17         </listener-class>
18     </listener>
19 
20     <!-- 编码过滤器 -->
21     <filter>
22         <filter-name>CharacterEncodingFilter</filter-name>
23         <filter-class>
24             org.springframework.web.filter.CharacterEncodingFilter
25         </filter-class>
26         <init-param>
27             <param-name>encoding</param-name>
28             <param-value>UTF-8</param-value>
29         </init-param>
30         <init-param>
31             <param-name>forceEncoding</param-name>
32             <param-value>true</param-value>
33         </init-param>
34     </filter>
35     <filter-mapping>
36         <filter-name>CharacterEncodingFilter</filter-name>
37         <url-pattern>/*</url-pattern>
38     </filter-mapping>
39 
40 
41 
42     <!-- Spring MVC -->
43     <servlet>
44         <servlet-name>hello</servlet-name>
45         <servlet-class>
46             org.springframework.web.servlet.DispatcherServlet
47         </servlet-class>
48         <load-on-startup>0</load-on-startup>
49     </servlet>
50     <servlet-mapping>
51         <servlet-name>hello</servlet-name>
52         <url-pattern>*.htm</url-pattern>
53     </servlet-mapping>
54 
55     <session-config>
56         <session-timeout>60</session-timeout>
57     </session-config>
58 
59     <welcome-file-list>
60         <welcome-file>index.jsp</welcome-file>
61     </welcome-file-list>
62 </web-app>
63 

再来 写个controller

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --> 1 package com.ds.web;
 2 
 3 import java.io.IOException;
 4 import java.io.PrintWriter;
 5 
 6 import javax.servlet.http.HttpServletRequest;
 7 import javax.servlet.http.HttpServletResponse;
 8 
 9 import org.springframework.stereotype.Controller;
10 import org.springframework.web.bind.annotation.RequestMapping;
11 
12 
13 
14 
15 @Controller
16 @RequestMapping("/hello.htm")
17 public class HelloController {
18     
19     @RequestMapping(params = "method=forwardHello")
20     public void forwardHello(HttpServletRequest request,HttpServletResponse response) throws IOException {
21         
22         System.out.println(request.getParameter("name")+"成功的使用了HelloWorld");
23         
24         PrintWriter out = response .getWriter();
25         response.setContentType("text/html");
26         response.setCharacterEncoding("utf-8");
27         out.write(request.getParameter("name")+"成功的使用了HelloWorld");
28     }
29     
30 }
31 

第3 配置hello-servlet.xml

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --> 1 <beans xmlns="http://www.springframework.org/schema/beans"
 2     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 3     xmlns:p="http://www.springframework.org/schema/p"
 4     xmlns:aop="http://www.springframework.org/schema/aop"

 6     xmlns:jee="http://www.springframework.org/schema/jee"
 7     xmlns:tx="http://www.springframework.org/schema/tx"
 8     xsi:schemaLocation="

13            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
14 
15     <!--视图解析链  -->
16     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/"
17             p:suffix=".jsp" p:viewClass="org.springframework.web.servlet.view.JstlView"/>
18             
19     <!-- ②：启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
20     <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>        
21             
22     <!-- 对Controll组件进行扫描   通常要使用@Autowried（要进行自动bean的自动装配）都要进行一些xml配置可以通过这个标签来简化配置-->
23     <context:component-scan base-package="com.ds.web"/>
24 </beans>

第4 写个jsp

<!--<br /> <br /> Code highlighting produced by Actipro CodeHighlighter (freeware)<br /> http://www.CodeHighlighter.com/<br /> <br /> --> 1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 2 <%
 3 String path = request.getContextPath();
 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 5 %>
 6 
 7 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 8 <html>
 9   <head>
10     <base href="<%=basePath%>">
11     
12     <title>My JSP 'index.jsp' starting page</title>
13     <meta http-equiv="pragma" content="no-cache">
14     <meta http-equiv="cache-control" content="no-cache">
15     <meta http-equiv="expires" content="0">    
16     <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
17     <meta http-equiv="description" content="This is my page">
18     <!--
19     <link rel="stylesheet" type="text/css" href="styles.css">
20     -->
21     
22   </head>
23   
24   <body>
25     <form action="hello.htm?method=forwardHello" method="post">
26                 <span>Text:</span><input type="text" name="name">
27                 <input type="submit" value="Submit">
28             </form>
29   </body>
30 </html>
31
