Java 列出所有流程?
如何使用JNA 4.5.0获得Java中所有运行进程的列表 我已经尝试了以下代码:Java 列出所有流程?,java,windows,process,jna,Java,Windows,Process,Jna,如何使用JNA 4.5.0获得Java中所有运行进程的列表 我已经尝试了以下代码: WinNT winNT = (WinNT) Native.loadLibrary(WinNT.class, W32APIOptions.UNICODE_OPTIONS); winNT.HANDLE snapshot = winNT.CreateToolhelp32Snapshot(Tlhelp32.TH32CS_SNAPPROCESS, new WinDef.DWORD(0)); Thelp32.PROCESSE
WinNT winNT = (WinNT) Native.loadLibrary(WinNT.class, W32APIOptions.UNICODE_OPTIONS);
winNT.HANDLE snapshot = winNT.CreateToolhelp32Snapshot(Tlhelp32.TH32CS_SNAPPROCESS, new WinDef.DWORD(0));
Thelp32.PROCESSENTRY32.ByReference processEntry = new Tlhelp32.PROCESSENTRY32.ByReference();
while (winNT.Process32Next(snapshot, processEntry)) {
System.out.println(processEntry.th32ProcessID + "\t" + Native.toString(processEntry.szExeFile));
}
winNT.CloseHandle(snapshot);
但是它不起作用,因为它是为旧版本的JNA库编写的。您现在正在寻找的一些函数存在于
Kernel32
类中。通过一些小的修改,您的代码片段可以正常工作:
import com.sun.jna.Native;
import com.sun.jna.platform.win32.Kernel32;
import com.sun.jna.platform.win32.Tlhelp32;
import com.sun.jna.platform.win32.WinDef;
import com.sun.jna.platform.win32.WinNT;
public class Main {
public static void main(String[] args) {
Kernel32 kernel = Kernel32.INSTANCE;
WinNT.HANDLE snapshot = kernel.CreateToolhelp32Snapshot(Tlhelp32.TH32CS_SNAPPROCESS, new WinDef.DWORD(0));
Tlhelp32.PROCESSENTRY32.ByReference processEntry = new Tlhelp32.PROCESSENTRY32.ByReference();
while (kernel.Process32Next(snapshot, processEntry)) {
System.out.println(processEntry.th32ProcessID + "\t" + Native.toString(processEntry.szExeFile));
}
kernel.CloseHandle(snapshot);
}
}
