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;
