如何验证外部进程是否异常终止？

Question

以下代码片段运行外部进程：

ProcessBuilder pb = new ProcessBuilder("C:\Program Files\Java\jdk1.8.0_111\bin\java.exe", 
                "-cp",
                "D:\nsd-rest\target\classes",
                "com.dataart.ExternalProcess"); //java -cp D:\nsd-rest\target\classes my.package.ExternalProcess
Process process = pb.start();
System.out.println(process.waitFor(10, TimeUnit.SECONDS)); // prints true

外部流程如下所示：

public class ExternalProcess {
    public static void main(String[] args) { 
       throw new RuntimeException();
    }
}

尽管外部进程抛出异常，但第一个片段打印为真。

有没有办法验证进程是否异常完成？

Answer 1

来自Process#waitFor(长时间超时， TimeUnit 单位）Javadoc

Returns: true if the subprocess has exited and false if the waiting time elapsed before the subprocess has exited.

您可以使用 Process#exitValue() 检索退出值，并检查它是否为 != 0

Returns: the exit value of the subprocess represented by this Process object. By convention, the value 0 indicates normal termination.
