忽略Java中的SIGINT [英] Ignore SIGINT in Java

问题描述

我在Unix上的本地共享库中使用Java包装器( JRI ).本机库(R的基于C的REPL实现)在内部处理SIGINT.使用Java包装程序时，当我使用以下命令将SIGINT发送到进程时，Java应用程序退出:

I'm using a Java wrapper for a native shared library on Unix (JRI). The native library (a C based REPL implementation for R) handles SIGINT internally. When using the Java wrapper, the Java application quits when I send a SIGINT to the process using:

kill -SIGINT pid

kill -SIGINT pid

我希望SIGINT完全由本地库在内部处理.

I'd prefer for the SIGINT to be entirely handled by the native library internally.

是否有一种简单的方法可以使Java完全忽略SIGINT，但仍然让本机库接收它?

Is there an easy way to make Java completely ignore a SIGINT but still have the native library receive it?

添加:

最好在Unix和OSX上工作.

Preferably this would work on Unix and OSX.

推荐答案

没有标准的API，但是，如果您使用的是Sun JDK，则可以使用

There is no standard API for it, but if you are using the Sun JDK, you can use sun.misc.Signal and sun.misc.SignalHandler. Example from the docs:

SignalHandler handler = new SignalHandler () {
    public void handle(Signal sig) {
        ... // handle SIGINT
    }
};
Signal.handle(new Signal("INT"), handler);
