System.out.println("Password: " +val);

//默认端口号
int port=21;
System.out.println("Port: " +21);

//获得url
val = value.substring(value.indexOf("@")+1,value.length());
val = val.substring(0, val.indexOf("/"));

//获得path
val = value.substring(value.indexOf("@")+1,value.length());

输出：

Protocal: ftp

Password: vtpicms

Port: 21

Url: 172.25.39.4

Path: syncdir/remote/CCTV/response/CCTV_SOAP_RESULT_CCTV_SOAP_MSG_201305131454466493664.xml
