如果是使用nodejs+express3这个经典的组合，那么有一种很方面的处理回调函数异常的方法：

1. 安装模块：express-domain-middleware

2. 加入如下的代码：

app.use(require('express-domain-middleware'));
app.use(function errorHandler(err, req, res, next) {logger.error('error on request %d %s %s: %j', process.domain.id, req.method, req.url, err);res.send(500, "there is an error in callback function");if(err.domain) {//you should think about gracefully stopping & respawning your server//since an unhandled error might put your application into an unknown state}
});
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
