Java 系列之spring学习--springmvc搭建（四）

一、建立java web 项目

　　

二、添加jar包

　　spring jar包下载地址http://repo.spring.io/release/org/springframework/spring/

　　

　　　2.1、导入jar包

　　　　

　　　　先不管哪些包的具体作用，直接全部导入。

　　　　

三、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!-- 所有的请求都会被dispatherservlet捕获 -->
  <servlet>
    <servlet-name>springmvc</servlet-name>
 	<init-param> 
 		<param-name>contextConfigLocation</param-name> 
 		<param-value>/WEB-INF/springmvc-servlet.xml</param-value> 
	 </init-param>
    <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>

四、新建一个控制器

package springmvc;

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

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class welcomeController extends AbstractController {

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
			HttpServletResponse arg1) throws Exception {
		// TODO Auto-generated method stub
		System.out.print("hello springmvc");
		return null;
	}

}

五、建立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: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-3.2.xsd   
    http://www.springframework.org/schema/tx   
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd  
    http://www.springframework.org/schema/context  
    http://www.springframework.org/schema/context/spring-context-3.2.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> 
    
	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
	<bean name="/welcome.html" class="springmvc.welcomeController">
	</bean>
	 <!-- 视图解释类 -->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/JSP/"/>  
        <property name="suffix" value=".jsp"/>  
    </bean>  
</beans>
