停止正在读取 MQ 的 nohup Java 进程

Question

I have a java process that runs in nohup which reads the message from MQ continuously. What is the best way to stop that process in a controlled manner instead of killing the process to stop abruptly.

Currently I have coded to match the incoming message with "STOP_THE_PROCESS" string and if it matches it will stop the process. Is there any other better way?

You can add so called 'shutdown port' to your java application: application will listen on specific port for shutdown command and terminate gracefully on receive.

Apache Tomcat uses this approach, with dedicated tcp socket.
