我正在使用 java Runtime.exec() 方法来执行 bat 文件，在 bat 文件中我编写了执行 jar 的代码。这个 jar 包含线程类，该线程类将无限时间池化rabbitmq 队列，如果找到消息，则对其执行操作，意思是该过程将无限运行。我想使用java代码终止这个进程，我也想知道这个方法是否能够在Linux操作系统上执行shall脚本。

Runtime.exec(...) returns Processobject which consists following methods
Runtime.exec(...) 返回Process包含以下方法的对象
- destroy()
- exitValue()
- getErrorStream()
- getInputStream()
- getOutputStream()
- waitFor()
- 破坏（）
- 退出值（）
- 获取错误流（）
- 获取输入流()
- 获取输出流（）
- 等待（）
you can call destroy() which kills the subprocess. The subprocess represented by this Process object is forcibly terminated.
or you can kill by passing taskkill /PID <process id>in Runtime.exec(...)or kill -9 <process id>
你可以调用 destroy() 来杀死子进程。该 Process 对象所代表的子进程被强制终止。或者你可以通过杀死taskkill /PID <process id>的Runtime.exec(...)或kill -9 <process id>

In Windows
在 Windows 中
Runtime rt = Runtime.getRuntime();
rt.exec("taskkill " +<Your process>);
In Linux
在 Linux 中
Runtime rt = Runtime.getRuntime();
rt.exec("kill -9 " +<Your process>);

Runtime.exec()returns a Process object, which is an handler for the process the exec method has created. To kill this process, you have to call Process.destroy();
Runtime.exec()返回一个 Process 对象，它是 exec 方法创建的进程的处理程序。要终止此进程，您必须调用Process.destroy();
