我有一个交互式java程序,允许用户将消息发送到服务器,服务器的行为类似于shell,接受用户的键盘输入并执行各种操作.

例如

myProgram> send "Login as James" to server

我的程序将解析用户输入并执行操作,在这种情况下,它将向服务器发送消息"Login as James".

我支持其"退出"的命令之一,它将关闭所有服务器连接,清理资源并关闭应用程序.以及处理此退出命令的代码是

private void shutdown()
{
  closeAllConnection();
  cleanup();
  System.out.println("Thank you for using the tool, have a nice day!");
  System.exit(0);
}

当我对我的代码运行findbug时,会引发DM_EXIT错误

Pattern id: DM_EXIT, type: Dm, category: BAD_PRACTICE


Invoking System.exit shuts down the entire Java virtual machine. This should only been done when it is appropriate. Such calls make it hard or impossible for your code to …
