apacheFtpServer集成spring由web容器控制启动和关闭

ApacheFtpServer是一个100%纯Java实现的FTP服务器，基于网络框架apache MINA实现，可支撑多并发用户。FtpServer可以独立运行作为一个Windows服务或Unix/Linux守护进程,或嵌入到Java应用程序，提供对内部集成spring应用程序支持。下面介绍apacheFtpServer与spring集成，交由spring控制ApacheFtpServer的启动与关闭。

1.      初始化创建MyFtpServer:

import java.io.File;import org.apache.ftpserver.FtpServer;import org.apache.ftpserver.FtpServerFactory;import org.apache.ftpserver.ftplet.FtpException;import org.apache.ftpserver.usermanager.ClearTextPasswordEncryptor;importorg.apache.ftpserver.usermanager.PropertiesUserManagerFactory;import org.apache.ftpserver.usermanager.SaltedPasswordEncryptor; public class MyFtpServer {       FtpServer server =null;       public void initFtp(){             FtpServerFactoryserverFactory = new FtpServerFactory();             ListenerFactorylistenerFactory = new ListenerFactory();              // replacethedefault listener             listenerFactory.setPort(21);             serverFactory.addListener("default",listenerFactory.createListener());             PropertiesUserManagerFactoryuserManagerFactory = newPropertiesUserManagerFactory();             userManagerFactory.setFile(newFile(          "D:\\stcaimis\\apache-ftpserver-1.0.3\\res\\conf\\users2.properties"));              //设置盐化hash加密算法             //SaltedPasswordEncryptorsalterpassword = new SaltedPasswordEncryptor();            //userManagerFactory.setPasswordEncryptor(salterpassword);             //设定了用户输入密码时 直接输入明文             userManagerFactory.setPasswordEncryptor(new ClearTextPasswordEncryptor());                             serverFactory.setUserManager(userManagerFactory.createUserManager());              server=serverFactory.createServer();              }            public void start(){                           try {                    server.start();                    System.out.println("serverstarting");              }catch(FtpException e) {                     //TODOAuto-generated catch block                    e.printStackTrace();              }       }       public void stop() {              server.stop();             System.out.println("serveris stopped");       }   }

spring 监听器在启动Web 容器时，自动装配SpringapplicationContext.xml 的配置信息。在application-context.xml文件中配置myFtpServer javabean

 <beanid="StrongFTP"class="com.st.caims.lxj.test.MyFtpServer"></bean>

2. web.xml配置ftpListener，自定义监听器FtpServerListener implements ServletContextListener接口，启动web容器时，自动执行contextInitialized()方法，web容器关闭时调用contextDestroyed()方法。

 

import javax.servlet.ServletContextEvent;import javax.servlet.ServletContextListener;import org.apache.ftpserver.impl.DefaultFtpServer;import org.springframework.web.context.WebApplicationContext;importorg.springframework.web.context.support.WebApplicationContextUtils; public class FtpServerListener implementsServletContextListener{     //tomcat容器关闭时调用方法stop ftpServer  public voidcontextDestroyed(ServletContextEvent sce) {           WebApplicationContextctx=WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());         MyFtpServerserver=(MyFtpServer)ctx.getServletContext().getAttribute("FTPSERVER_CONTEXT_NAME");    server.stop();  sce.getServletContext().removeAttribute("FTPSERVER_CONTEXT_NAME");  System.out.println("Stopping FtpServer");  }   //spring 容器初始化调用方法startFtpServer  public voidcontextInitialized(ServletContextEvent sce) {   System.out.println("Starting FtpServer");     WebApplicationContextctx=WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());     MyFtpServer server=(MyFtpServer) ctx.getBean("StrongFTP");   sce.getServletContext().setAttribute("FTPSERVER_CONTEXT_NAME",server);     try {                    server.initFtp();           server.start();    System.out.println("FtpServer started");     } catch (Exceptione){       thrownewRuntimeException("Failed to start FtpServer", e);     }   } }
