Java 处理子进程
我有一个简单的脚本，它使用 ProcessBuilder 将输出写入控制台。 OutputStreamWriter 请参阅：
较早的线程。我相信我的问题在于生成了一个子进程并且初始的父进程被终止。导致 OutputStreamWriter 抛出 java.io.IOException：损坏的管道异常。鉴于应用程序正在生成第二个进程，我如何将我的 OutputStreamWriter 连接到这个新进程？包括能够读回它生成的输出？这在 Java 中可能吗？ Surly java 应该能够跟踪生成的进程。
谢谢
I have a simple script that writes output to the console using ProcessBuilder. And OutputStreamWriter see:
Java Process with Input/Output Stream
An earlier thread. I believe my problem rests with the fact a sub process is spawned and the initial Parent process is killed. Resulting in the OutputStreamWriter to throw a java.io.IOException: Broken pipe exception. Given the application is spawning a second process how can I connect my OutputStreamWriter to this new process? Including being able to read back the output it is generating? Is this even possible in Java? Surly java should be able to follow onto the spawned process.
Thanks

您是否正在调用 waitFor() 你正在运行的进程？这应该确保你的父母不会在孩子之前完成。您可能还想看看 commons exec，这是一个开源库，旨在让您的生活变得更加美好在 Java 中运行单独的进程时更容易。
Are you calling waitFor() on the process you are running? That should ensure you're parent doesn't complete before the child. You may also want to look at commons exec, which is an open source library designed to make your life easier when running separate processes in Java.
