使用Runtime.exec / ProcessBuilder.start以低优先级启动Java进程？

使用启动命令。它取决于Windows，但可以满足您的需求。我读过没有跨平台的方法。

ProcessBuilder pb = new ProcessBuilder("cmd", "/C start /B /belownormal javaws -version");System.out.println("Before start");Process start = pb.start();

甚至可以读取输入端错误流。

等待：

ProcessBuilder pb = new ProcessBuilder("cmd", "/C start /B /belownormal /WAIT javaws -sdasd");System.out.println("Before start");Process start = pb.start();start.waitFor();System.out.println("Done");

对于过早销毁：

ProcessBuilder pb = new ProcessBuilder("cmd", "/C start /B /belownormal /WAIT javaws -sdasd");System.out.println("Before start");Process start = pb.start();start.destroy();start.waitFor();System.out.println("Done");
