首先你要Spring全部的包导入
1、配置前端控制器DispatcherServlet 在web.xml中
<?xml version="1.0" encoding="UTF-8"?
>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>spring</servlet-name><!--src下[servletname]-servlet.xml中的servletname一一致-->
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/spring-servlet.xml</param-value><!--默认DispatcherServlet会载入WEB-INF/[DispatcherServlet的Servlet名字]-servlet.xml配置文件->
</init-param>
<load-on-startup>1</load-on-startup><!--表示启动容器室初始化该servlet-->
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern><!--表示哪些请求交给Spring Web MVC处理， “/” 是用来定义默认servlet映射的。
也能够如“*.html”表示拦截全部以html为扩展名的请求。-->
</servlet-mapping>
</web-app>
2、建立一个HelloWorldController
package com.iss.control;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloWorldController implements Controller {
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("message", "helloworld");
modelAndView.setViewName("hello");//设置视图名
return modelAndView;//返回模型数据和逻辑视图名
}
}
3、配置spring-servlet.xml
<?
xml version="1.0" encoding="UTF-8"?>
<!-- Bean头部 -->
<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">
<!-- HandlerMapping -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
<!-- HandlerAdapter -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>
<!-- ViewResolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<!--处理器 -->
<bean name="/hello" class="com.iss.control.HelloWorldController"/>
</beans>
<!--
InternalResourceViewResolver：用于支持Servlet、JSP视图解析。
viewClass：JstlView表示JSP模板页面须要使用JSTL标签库。classpath中必须包括jstl的相关jar包；
prefix和suffix：查找视图页面的前缀和后缀（前缀[逻辑视图名]后缀），比方传进来的逻辑视图名为hello。则该该jsp视图页面应该存放在“WEB-INF/jsp/hello.jsp”；
-->4、在WEB-INF下建立jsp目录并新建一个hello.jsp文件注意hello已经在HelloWorldContoller中设置不能够任意命名
<body>
${message }
</body>
5、在浏览器地址栏输入
http://localhost:8080/SpringMVC01/hello 页面出现helloworld!证明你成功了！
