[ java ] spring-mvc!

一早上来公司上班，又是没网的节奏！什么又做不了！

想起昨天了看了些spring-mvc的文档。

就来配置下spring-mvc。

由于没有网络，那就只有spring的官方文档了。

1. 先是建立个基本工程就ok了。

2. 引入spring-mvc的开发包。根据开发文档只需要三个包。

以下是spring的文档：

Copy libraries to 'WEB-INF/lib'

First create a 'lib' directory in the'war/WEB-INF' directory. Then, from the Spring distribution, copyspring.jar(fromspring-framework-2.5/dist) andspring-webmvc.jar (fromspring-framework-2.5/dist/modules) to the new'war/WEB-INF/lib' directory. Also, copycommons-logging.jar(fromspring-framework-2.5/lib/jakarta-commons) to the'war/WEB-INF/lib' directory. These jars will be deployed to the server and they are also used during the build process.

3. 修改web.xml，添加一个servlet.如下：

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"         xmlns="http://java.sun.com/xml/ns/j2ee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee          http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >  <servlet>    <servlet-name>springapp</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springapp</servlet-name>    <url-pattern>*.htm</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>      index.jsp    </welcome-file>  </welcome-file-list></web-app>

4 在WEB-INF 下新建springmvc-servlet.xml.这里的命名为你的工程加上servlet.

   然后在文档中配置你需要的controller.

 

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">  <!-- the application context definition for the springapp DispatcherServlet -->  <!--         控制器，hello.htm的路径，都会经过该控制器。有点像在struts2中struts.xml中配置action的感觉。每一个路径对应个cotroller.在srping-mvc中没有action的概念，只有cotroller.   -->  <bean name="/hello.htm" class="springapp.web.HelloController"/></beans>

5 建立controller.并在webroot下面建立hello.jsp.

package springmvc.web;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class HelloController implements Controller{protected final Log logger = LogFactory.getLog(getClass());public ModelAndView handleRequest(HttpServletRequest arg0,HttpServletResponse arg1) throws Exception {logger.info("run hello Controller");return new ModelAndView("hello.jsp");}}

然后在浏览器中输入 http://localhost:8080/springmvc/hello.htm.即可显示hello.jsp页面。
