[英]Invoke Powershell scripts from Java
我想從java調用我的powershell腳本。 可以嗎? 我嘗試使用以下代碼,但流未關閉。
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
public class TestPowershell {
public static void main(String[] args) throws IOException
{
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec("powershell C:\\testscript.ps1");
InputStream is = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader reader = new BufferedReader(isr);
String line;
while ((line = reader.readLine()) != null)
{
System.out.println(line);
}
reader.close();
proc.getOutputStream().close();
}
}
java是否會調用執行創建遠程會話和執行cmdlet的powershell腳本?
我們是否支持在java中調用powershell腳本?
任何人都可以請你幫忙。
等待您的回復。
謝謝,rammj
在啟動進程( runtime.exec()
)之后,添加一行來關閉進程的輸入流(JAVA調用輸出流!!):
proc.getOutputStream().close();
是的,我們可以使用powershell腳本創建遠程會話和執行cmdlet。
將以下Power shell腳本保存到testscript.ps1
#Constant Variables
$Office365AdminUsername="YOUR_USERNAME"
$Office365AdminPassword="TOUR_PASSWORD"
#Main
Function Main {
#Remove all existing Powershell sessions
Get-PSSession | Remove-PSSession
#Encrypt password for transmission to Office365
$SecureOffice365Password = ConvertTo-SecureString -AsPlainText $Office365AdminPassword -Force
#Build credentials object
$Office365Credentials = New-Object System.Management.Automation.PSCredential $Office365AdminUsername, $SecureOffice365Password
Write-Host : "Credentials object created"
#Create remote Powershell session
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell -Credential $Office365credentials -Authentication Basic –AllowRedirection
Write-Host : "Remote session established"
#Check for errors
if ($Session -eq $null){
Write-Host : "Invalid creditials"
}else{
Write-Host : "Login success"
#Import the session
Import-PSSession $Session
}
#To check folder size
Get-MailboxFolderStatistics "YOUR_USER_NAME" | Select Identity, FolderAndSubfolderSize
exit
}
# Start script
. Main
Java代碼:
try {
String command = "powershell.exe \"C:\\testscript.ps1\"";
ExecuteWatchdog watchdog = new ExecuteWatchdog(20000);
Process powerShellProcess = Runtime.getRuntime().exec(command);
if (watchdog != null) {
watchdog.start(powerShellProcess);
}
BufferedReader stdInput = new BufferedReader(new InputStreamReader(powerShellProcess.getInputStream()));
String line;
System.out.println("Output :");
while ((line = stdInput.readLine()) != null) {
System.out.println(line);
}
} catch (Exception e) {
e.printStackTrace();
}
如果沒有輸出,請嘗試以下方法: powerShellProcess.getErrorStream()
而不是powerShellProcess.getInputStream()
。 它會顯示錯誤。
現在,您可以使用jPowerShell輕松完成
powerShell = PowerShell.openSession();
//Print results
System.out.println(powerShell.executeScript("\"C:\\testscript.ps1\"").getCommandOutput());
powerShell.close();
