springMVC入门配置及helloworld实例

1. 新建web project

2. 往lib里copy必须的jar

3. 改写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
	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_3_0.xsd">
  <display-name></display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <servlet>
  	<servlet-name>springMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

4. 在WEB-INF下新建 springMVC-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:p="http://www.springframework.org/schema/p"
    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/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"> 

    <!-- ViewResolver 视图解析器 -->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

5. src下新建package: com.tgb.web.controller   class:  HelloWorldController.java　

package com.tgb.web.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.ModelAndView;

public class HelloWorldController implements org.springframework.web.servlet.mvc.Controller{

	@Override
	public ModelAndView handleRequest(HttpServletRequest arg0, HttpServletResponse arg1) throws Exception {
		System.out.println("---hello wly--------");
		return new ModelAndView("/welcome");
	}
}

6. 新建welcome.jsp, 在WEB-INF下

7. 修改配置 文件 springMVC-servlet.xml

<bean name="/test1/helloworld" class="com.tgb.web.controller.HelloWorldController"></bean>

8. IE测试:  http://localhost:8080/springMVC1/test1/helloworld
