如果在不知道的情况下,想了解当前虚拟机支持的协议类型,那么可以参考本文。
本文的测试实验出自:
-
public class TestURLProtocol {
-
-
public static void main(String[] args) {
-
String host = "";
-
String file = "/index.html";
-
-
String[] schames = {"http", "https", "ftp", "mailto", "telnet", "file", "ldap", "gopher",
-
"jdbc", "rmi", "jndi", "jar", "doc", "netdoc", "nfs", "verbatim", "finger", "daytime", ""
-
+ "systemresource"};
-
for (int i= 0; i < schames.length; i++) {
-
try {
-
URL url = new URL(schames[i], host, file);
-
System.out.println(schames[i] + " is supported\r\n");
-
} catch (MalformedURLException e) {
-
// TODO Auto-generated catch block
-
-
e.printStackTrace();
-
System.out.println(schames[i] + " is not supported\r\n");
-
}
-
}
-
-
}
测试结果如下:
-
http is supported
-
