Unable to open debugger port (localhost:8787): java.io.IOException "handshake failed - connection prematurally closed"。
我将通过standalone.sh --debug启动野生
Process ps = new ProcessBuilder("iexplore.exe").start(); 我只是调用这个函数并浏览打开的应用程序。在这里,ps.destroy();正在处理相同的代码,但我想从另一个java代码中杀死这个ps对象。在Java7中没有PID的概念,我也使用了Serializable,但没有用到。对此有什么解决方案吗?

new ParentClass("1"),
new ChildClass("2")
};
这个很好用。但我想知道,这是正确的做法,还是有更容易/更清洁的方式?
