在java中使用不同的用户调用外部进程 [英] Invoking an external process with a different user in java

问题描述

我们有一个作为Windows服务运行的java应用程序。一个特定的功能需要执行一个二进制文件，但是有一个不同的用户然后启动了应用程序。

We have a java application running as a windows service. A particular functionality needs to execute a binary but with a different user then which started the application.

我们有什么办法可以通过'Run as a不同的用户风格。

Is there any way by which we can invoke an exe with 'Run as a different user' style.

我检查了ProcessBuilder的API，但没有找到任何与用户相关的内容。是否有任何第三方工具来实现此目的。

I checked API of ProcessBuilder but didn't found anything related to user. Is there any 3rd party tool to achieve this.

推荐答案

您可以使用 PSExec 以不同的用户身份执行进程。命令行如下所示：

You can use PSExec to execute processes as a different user. The command line looks like:

psexec.exe -u username -p password mybinary.exe

然后你可以使用ProcessBuilder围绕此建立命令。

You can then use ProcessBuilder to build the command around this.

编辑：以下是如何执行此操作的示例：

here is an example of how you can do it:

public int startProcess(String username, String password, 
        String executable, String... args) throws IOException {

    final String psexec = "C:\\PsTools\\psexec.exe"; //psexec location

    //Build the command line
    List<String> command = new LinkedList<String>();
    command.add(psexec);

    if(username != null) {
        command.add("-u");
        command.add(username);
        command.add("-p");
        command.add(password);
    }

    command.add(executable);
    command.addAll(Arrays.asList(args));

    ProcessBuilder builder = new ProcessBuilder(command);
    Process process = builder.start();

    int returnCode;

    try {
        returnCode = process.waitFor();
    } catch (InterruptedException e) {
        returnCode = 1;
    }

    return returnCode;
}

然后您可以像这样使用它：

You can then use it like this:

startProcess("Bob", "Password", "Notepad.exe", "C:\\myfile.txt");
