如何从Java程序内部运行PowerShell脚本作为Windows服务？

Question

I have the following code that runs a windows service from inside Java.The code uses JInterop Java library, JInterop is a pure Java COM client for windows COM server. More details of JIntop are available here [ http://fishi.devtail.io/weblog/2015/01/21/pure-java-dcom-bridge-j-interop/]

    String cmdFile = "service.bat";
results = wbemServices_dispatch.callMethodA(
                "Get", new Object[]{ new JIString("Win32_Process"),
                new Integer(0), JIVariant.OPTIONAL_PARAM()});

        IJIDispatch wbemObjectSet_dispatch = (IJIDispatch)JIObjectFactory.narrowObject(
                (results[0]).getObjectAsComObject());
results = wbemObjectSet_dispatch.callMethodA("Create",
                new Object[]{ new JIString(targetFilePrefix + cmdFile),
                JIVariant.OPTIONAL_PARAM(),
                JIVariant.OPTIONAL_PARAM()});

Is it possible to run a powershell file(.ps1) as a service in the same manner as above using the same library, or in some other way.

Answer 1

You can create a batch file which, in-turns, can trigger a powershell script like this:

@echo off
Powershell.exe set-executionpolicy remotesigned -File  C:\folder\MyScript.ps1
pause

Save it as "Trigger_ps.bat"

Then you can use the sc command to create a windows service by mentioning this batch file path like this:

SC CREATE PS_Trigger_Service Displayname= "PS_Trigger_Service" binpath= "C:\folder\Trigger_ps.bat" start= auto

This should solve your purpose.

Answer 2

You can use SC or New-Service to create a Windows Service which,in-turns, can run a ps1 file like this:

sc.exe create "PS1Service" binPath= "powershell.exe -NoLogo -Path D:\Script.ps1"

Reference Link for Creating User Defined Service

Reference Link to Usage of New-Service

This entire thing you can call it from JAVA and that should solve your purpose.

If you have Visual Studio, then you can directly do like Run PS Code as Windows Service

Hope it helps.
