基於maven的springmvc的helloworld
1:新建一個maven-archetype-webapp項目->springmvc-helloworld
2:創建src/main/java,src/test/resources,src/test/java3個目錄
3:在pom中添加依賴包，需要添加的jar包如下：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>3.1.3.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.1.3.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.1.3.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-expression</artifactId>
<version>3.1.3.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.1.3.RELEASE</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1-b02</version>
<type>jar</type>
<scope>provided</scope>
</dependency>4:修改jdk版本,maven默認的jdk版本爲1.5
5:在web.xml中添加DispatcherServlet這個servlet其內容如下
<servlet>
<servlet-name>chapter2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 表示啓動容器時初始化該Servlet -->
<load-on-startup>1</load-on-startup>
<!-- 可以使用如下配置使用配置的config文件
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-servlet-config.xml</param-value>
</init-param> -->
</servlet>
<servlet-mapping>
<servlet-name>chapter2</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>package com.springmvc.sjc.controller;
import java.util.HashMap;
import java.util.Map;
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 HelloWorld implements Controller{
private String viewPage;
private String helloWorld;
public String getHelloWorld() {
return helloWorld;
}
public void setHelloWorld(String helloWorld) {
this.helloWorld = helloWorld;
}
public String getViewPage() {
return viewPage;
}
public void setViewPage(String viewPage) {
this.viewPage = viewPage;
}
@SuppressWarnings("unchecked")
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
Map model=new HashMap();
model.put("helloWorld",getHelloWorld());
return new ModelAndView(getViewPage(),model);
}
}7:在WEB-INF目錄下創建配置文件：
注：其servlet前面的部分要與web.xml中配置的DispatcherServlet的攔截器名稱一致(當然，如果不一致，需要在web.xml的該攔截器下進行配置)chapter2-servlet.xml
其中的內容如下：
<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="helloWorld.do">helloWorldAction</prop>
</props>
</property>
</bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/>
</bean>
<bean name="helloWorldAction" class="com.springmvc.sjc.controller.HelloWorld">
<property name="helloWorld">
<value>Good Luck!</value>
</property>
<property name="viewPage">
<value>WEB-INF/index.jsp</value>
</property>
</bean>
</beans>8:在WEB-INF目錄下創建index.jsp該jsp的內容如下：
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head><title>第一個SpringMVC實例</title></head>
<%String str=(String)request.getAttribute("helloWorld"); %>
<body>
<H1><%=str %></H1>
</body>
</html>返回的界面上顯示：Good Luck!
