Simple JNA library to get the current machine's hostname from Java
I was frustrated to find that the common-ish Java idiom of
InetAddress.getLocalHost().getHostName() was returning localhost in some cases that only seemed solved by tinkering with
/etc/hosts. This library uses JNA to directly call the C library's gethostname method (or
Kernel32Util.getComputerName() on Windows), and gives you back the hostname it got.
You can get it from maven central with a dependency like this...
<dependency> <groupId>com.kstruct</groupId> <artifactId>gethostname4j</artifactId> <version>1.0.0</version> </dependency>
...and then use it in your code to get the hostname with something like...
import com.kstruct.gethostname4j.Hostname; ... String hostname = Hostname.getHostname();
