利用JBuilder 2005开发Spring实例

利用JBuilder 2005开发Spring实例2010-12-041. 下载spring包，网址如下：

http://www.springframework.org/download.html

解压后的目录中包含了dist、lib等子目录

2. 在JBuilder2005中增加spring库，选择菜单Tools-Configure-Libraries，在弹出的对话框中点击New按钮，输入spring库的名称：spring，点击Add按钮，将dist目录中的所有jar文件增加到spring库中

3. 新建工程文件，选菜单File-New Project，给工程文件取名为myProject

设置工程文件的属性，选菜单Project-Project Properties，选择Tomcat作为，将spring库加入Path/Required Libraries。因为例子中用到了log4j，将包含了log4j的库加入Path/Required Libraries，注意到lib目录下有两个子目录log4j和jakarta-commons，它们的用法是不同的,如下面的代码片断所示：

log4j

import org.apache.log4j.Level;
import org.apache.log4j.Logger;
public class SpringappController implements Controller {
  /** Logger for this class and subclasses */
  static Logger logger = Logger.getLogger（SpringappController.class）;
  jakarta-commons
  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;
  public class SpringappController implements Controller {
   /** Logger for this class and subclasses */
   protected final Log logger = LogFactory.getLog（getClass（））;

4. 新建Web模块，选菜单File-New，给Web模块取名为springapp

5. 新建hello.jsp文件如下：

<%@ page contentType="text/html; charset=Big5" %>
<html>
  <head><title>Example :: Spring Application</title></head>
<body>
  <h1>Hello - Spring Application</h1>
  <p>Greetings.</p>
</body>
</html>

6. 新建类文件SpringappController.java如下：

package spring;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
//import org.apache.commons.logging.Log;
//import org.apache.commons.logging.LogFactory;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
public class SpringappController implements Controller {
  /** Logger for this class and subclasses */
  // protected final Log logger = LogFactory.getLog（getClass（））;
  static Logger logger = Logger.getLogger（SpringappController.class）;
  public ModelAndView handleRequest（HttpServletRequest request, HttpServletResponse response）
  throws ServletException, IOException {
   logger.info（"SpringappController - returning hello view"）;
   return new ModelAndView（"hello.jsp"）;
  }
}

7. 修改web.xml文件

<？xml version="1.0" encoding="UTF-8"？>
<！DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
  <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>
