JRuby:如果运行时间太长就关闭 runScriptlet?

JRuby: closing runScriptlet if it takes too long?

我想使用 JRuby 到 运行 Ruby 脚本。

但是,我希望如果脚本花费的时间超过 t 秒,它会自动关闭。

这是我的尝试:

ScriptingContainer ruby = new ScriptingContainer();
int t = 3;

new Thread() {
                @Override
                public void run() {
                    try {
                        Thread.sleep(t * 1000); // Timeout
                        System.out.println("Timeout passed.");
                        ruby.terminate(); // This has no effect?
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }.start();

Object output = ruby.runScriptlet(scriptWithAnInfiniteLoop);
ruby.terminate(); // Terminate without timeout, at the end of the script

这是一个使用 已弃用 Thread.stop():

的答案
        ScriptingContainer ruby = new ScriptingContainer();
        int t = 5;

        String script = content;
        Thread runner = new Thread() {
            @Override
            public void run() {
                try {
                    ruby.runScriptlet(script);
                    ruby.terminate(); // Close normally.
                } catch (Exception e) {
                    ruby.terminate(); // Close if JRuby crashes.
                }
            }
        };

        Thread killer = new Thread() {
            @Override
            public void run() {
                try {
                    Thread.sleep(t * 1000);
                    runner.stop();
                    ruby.terminate(); // Close forcefully.
                } catch (Exception e) {}
            }
        };

        runner.start();
        killer.start();

由于我使用的是已弃用的方法,因此我不会将此标记为官方答案。
