java线程"main"中的异常java.net.UnknownHostException:测试:测试:未知错误OS ubuntu

Question

此错误与我上一次出现错误的问题有关InetAddress.getLocalHost().我发现了一个添加条目 的建议/etc/hosts:

myip     localhost
127.0.0.1   localhost
127.0.1.1   test5

但我的错误仍未解决.

我的代码:

import java.net.*;

public class InetAddressTest {
    public static void main(String args[]) throws UnknownHostException {
        InetAddress Address = InetAddress.getLocalHost();

    }
}

错误:

Exception in thread "main" java.net.UnknownHostException: Sachin: Sachin: unknown error
    at java.net.InetAddress.getLocalHost(InetAddress.java:1484)
    at InetAddressTest.main(InetAddressTest.java:6)

Answer 1

您的主机名是Sachin.在exception in thread "main" java.net.UnknownHostException: Sachin: Sachin: unknown error表明.

将Sachin添加到/ etc/hosts

myip     localhost
127.0.0.1   localhost
127.0.1.1   test5
127.0.0.1   Sachin
