java内嵌ftp服务器

首先到apache官方下载 ftp服务器 下载地址是

                  http://mina.apache.org/ftpserver/

解压后 apache-ftpserver-1.0.5/common/lib  下边的jar既是启动ftp的主要jar

一半只需要 如下几个

          ftplet-api-1.0.5.jar

         ftpserver-core-1.0.5.jar

          log4j-1.2.14.jar

         mina-core-2.0.0-RC1.jar

         slf4j-api-1.5.2.jar

         slf4j-log4j12-1.5.2.jar

新建工程  ftpserver  添加类 startFtpServer 代码如下

在ftpserver工程添加文件夹 conf

拷贝 apache-ftpserver-1.0.5/res/conf 下面文件：

     users.properties 到 conf目录下

在users.propertis中添加 
ftpserver.user.a.userpassword=a
ftpserver.user.a.homedirectory=c://myftp
ftpserver.user.a.enableflag=true
ftpserver.user.a.writepermission=true
ftpserver.user.a.maxloginnumber=0
ftpserver.user.a.maxloginperip=0
ftpserver.user.a.idletime=0
ftpserver.user.a.uploadrate=0
ftpserver.user.a.downloadrate=0

就相当于添加了一个用户a  密码是a

ftpserver中默认 密码被md5加密了

代码中 setPasswordEncryptor 重写了加密方法

import java.io.File;

public class startFtpServer {

/**

* @throws FtpException
*/
public static void main(String[] args) throws FtpException {
// TODO Auto-generated method stub
FtpServerFactory serverFactory = new FtpServerFactory();
ListenerFactory factory = new ListenerFactory();
factory.setPort(21);
// define SSL configuration
/**

* SslConfigurationFactory(); ssl.setKeystoreFile(new

* // set the SSL configuration for the listener
* factory.setSslConfiguration(ssl.createSslConfiguration());
* factory.setImplicitSsl(true);
*/
// replace the default listener
serverFactory.addListener("default", factory.createListener());

PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
userManagerFactory.setFile(new File(System.getProperty("user.dir")
+ "/conf/users.properties"));
userManagerFactory.setPasswordEncryptor(new PasswordEncryptor() {

public String encrypt(String pwd) {
// TODO Auto-generated method stub
return null;
}
//storedPassword 配置文件中配置的密码 passwordToCheck 是用户输入的密码
public boolean matches(java.lang.String passwordToCheck,
java.lang.String storedPassword) {
if (passwordToCheck.equals(storedPassword))
return true;
return false;
}

});
serverFactory.setUserManager(userManagerFactory.createUserManager());

// start the server
FtpServer server = serverFactory.createServer();

server.start();

}

}

下载个客户端 登陆试一下
