Apache FTPServer 集成到Spring WEB项目中
Apache FTPServer好东西，可以集成到自己的WEB项目中，单独用也非常不错。大家有兴趣可以研究一下，测试了一下和Spring WEB项目结合。留下代码如下：web.xml
<listener>
<listener-class>com.strong.utils.ftpservice.FtpServerListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/com/strong/spring/applicationFTP.xml
</param-value>
</context-param>
FtpServerListener.java
package com.strong.utils.ftpservice;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.apache.ftpserver.FtpServer;
import org.apache.ftpserver.impl.DefaultFtpServer;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
public class FtpServerListener implements ServletContextListener {
public void contextDestroyed(ServletContextEvent sce) {
System.out.println("Stopping FtpServer");
DefaultFtpServer server = (DefaultFtpServer) sce.getServletContext().getAttribute(FtpConstants.FTPSERVER_CONTEXT_NAME);
if (server != null) {
server.stop();
sce.getServletContext().removeAttribute("FTPSERVER_CONTEXT_NAME");
System.out.println("FtpServer stopped");
} else {
System.out.println("No running FtpServer found");
}
}
public void contextInitialized(ServletContextEvent sce) {
System.out.println("Starting FtpServer");
WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());
DefaultFtpServer server = (DefaultFtpServer) ctx.getBean("StrongFTP");
sce.getServletContext().setAttribute("FTPSERVER_CONTEXT_NAME", server);
try {
server.start();
System.out.println("FtpServer started");
} catch (Exception e) {
throw new RuntimeException("Failed to start FtpServer", e);
}
}
}
applicationFTP.xml
<server xmlns="http://mina.apache.org/ftpserver/spring/v1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://mina.apache.org/ftpserver/spring/v1 http://mina.apache.org/ftpserver/ftpserver-1.0.xsd"
id="StrongFTP" max-logins="500" anon-enabled="false" max-anon-logins="123" max-login-failures="124" login-failure-delay="125">
<listeners>
<nio-listener name="default" port="2222" implicit-ssl="false" idle-timeout="60" local-address="127.0.0.1" />
</listeners>
<file-user-manager file="users.properties" encrypt-passwords="true" />
</server>
具体参数就不解释了，大家看文档。大概的做法是做一个ServletContextListener，tomcat启动时开始ftp服务器，结束时停止ftp服务器。
