在 Windows 中，您可以通过名称找到一个进程，如下所示：

tasklist | FIND "applicationName"

Hope this will help you out:

wmic process where "name like '%application.jar%'" get processid,commandline

or

wmic process where "name like '%jar%'" get processid,commandline

or

wmic process where "name like '%java%'" get processid,commandline

您可以使用Windows Powershell执行此操作以获取为运行 Java 应用程序而调用的命令和进程 ID：

String command = "powershell.exe  Get-WmiObject win32_process -Filter \"name='javaw.exe' and commandline like '%filename.jar%'\"|select Pid,CommandLine"

Answer 4

您可以使用 jdk 中的jvisualvm ： %JAVA_HOME%/bin/jvisualvm 。
