springmvc入门程序

工程目录如图所示



步骤一：添加jar包

jar包如工程目录所示

步骤二：在web.xml文件里面配置DispatcherServlet

<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>

步骤三：在工程目录下面创建资源文件夹，命名为config，并在该目录下面创建springmvc.xml配置文件(如工程目录所示)

步骤四：在src目录下创建第一个控制器MyController，并创建视图文件hello.jsp（如工程目录所示）

该文件内容如下

package com.yyf.test;

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 MyController implements Controller {

@Override
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
ModelAndView modelAndView=new ModelAndView();
modelAndView.setViewName("hello");
return modelAndView;
}

}

步骤五：配置springmvc.xml文件，内容如下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 
<!-- 配置handler -->
<bean name="/hello.action" class="com.yyf.test.MyController"></bean>

<!-- 处理器映射器 -->
<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

<!-- 处理器适配器 -->
<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" />

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

</beans>

步骤六：部署项目，调试程序

在地址栏输入url
http://localhost:8080/springmvc1/hello.action
结果如下
