Spring MVC 配置

要在web项目中使用SpringMVC首先要对web.xml进行如下配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>Net1</display-name>
  <!-- Spring MVC -->
  <servlet>
  	<servlet-name>Dispatcher</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:com/servlet.xml</param-value>
  	</init-param>
  	
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>Dispatcher</servlet-name>
  	<url-pattern>*.do</url-pattern>
  </servlet-mapping>
  
  <!-- spring configuration -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:com/applicationContext.xml</param-value>
  </context-param>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

然后进行applicationContext.xml的配置当然这个比较简单，也可以不进行配置。
但是这个文件一定要有。这个与SpringMVC无关

然后配置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"
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">

<!-- spring mvc  -->
<context:annotation-config />

<!-- scan controller -->
<context:component-scan base-package="controller"></context:component-scan>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="0" /> 
</bean>

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp" />

<!-- upload configuration -->
<!--
<bean id="multiResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"></property>
<property name="maxUploadSize" value="2147483648"></property>
</bean>
-->
</beans>

然后再controler包中写controller
package controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class FirstController {

@RequestMapping("/vets")
public String displayOwner(Model model){
//model.addAttribute("owner", ownerId);
return "display";
}
}

还有在webRoot下的jsp文件夹下创建一个display.jsp就可以了
最后启动服务器，输入http://localhost:8080/站点名称/vets.do就可以看到display.jsp了。
