这是upload类的方法：

public class Upload {

public static String upload(FormFile formfile,String dirPath,int port){

String savePath="";

String ip="";

try{

String filename = formfile.getFileName().trim(); // 文件名

if (!"".equals(filename)) {

InputStream ins = formfile.getInputStream();

String currentPath=dirPath+ File.separatorChar + filename;  //文件保存路径

OutputStream os = new FileOutputStream(currentPath);

int bytesRead = 0;

byte[] buffer = new byte[8192];

while ((bytesRead = ins.read(buffer, 0, 8192)) != -1) {

os.write(buffer, 0, bytesRead);

}

boolean isWindows=isWindowsOS();  //判断是否是windows系统

if(isWindows){

InetAddress address=InetAddress.getLocalHost();

ip=address.getHostAddress();  //获取ip地址

System.out.println("windows ip地址："+ip);

}

else{    //如果是Linux系统

ip=Tools.getLinuxIP();

System.out.println("linux ip地址："+ip);

}

savePath="http://"+ip+":"+port+"/channelProject/upload/";   //保存到数据库的地址,图片上传到服务器端

savePath+=filename;

os.close();

ins.close();

}

}

catch (Exception e) {

e.printStackTrace();

System.out.println("上传出现错误!!");

}

return savePath;

}

/*

* @return true---是Windows操作系统

*/

public static boolean isWindowsOS(){

boolean isWindowsOS = false;

String osName = System.getProperty("os.name");

if(osName.toLowerCase().indexOf("windows")>-1){

isWindowsOS = true;

}

return isWindowsOS;

}

}

以下是Tools类下的getLinux的方法：

public class Tools {

public static String getLinuxIP() throws SocketException{

//根据网卡取本机配置的IP

Enumeration netInterfaces=NetworkInterface.getNetworkInterfaces();

InetAddress ipAddress = null;

String ip="";

while(netInterfaces.hasMoreElements())

{

NetworkInterface ni=(NetworkInterface)netInterfaces.nextElement();

if(!ni.getName().equals("eth0")){

continue;

}

else{

Enumeration> e2=ni.getInetAddresses();

while(e2.hasMoreElements()){

ipAddress=(InetAddress) e2.nextElement();

if(ipAddress instanceof Inet6Address)

continue;

ip=ipAddress.getHostAddress();

System.out.println("getLinuxIp:"+ip);

}

break;

}

}

return ip;

}

}
