“重试”的设计模式失败的逻辑？

本文介绍了“重试”的设计模式失败的逻辑？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在写一些重新连接逻辑，以定期尝试建立一个到远程终端的连接。基本上，代码如下所示：

public void establishConnection（）{ try { this。 connection = newConnection（）; } catch（IOException e）{ //连接失败，再试一次。 try {Thread.sleep（1000）; } catch（InterruptedException e）{}; 建立连接（）; } }

我已经解决了这个一般问题，代码类似于以上在很多场合，但我感到很不满意的结果。有没有设计用于处理这个问题的设计模式？

解决方案

一个值得注销的图书馆是 Sarge ，根据定义的计划自动执行重试。

I'm writing some reconnect logic to periodically attempt to establish a connection to a remote endpoint which went down. Essentially, the code looks like this:

public void establishConnection() { try { this.connection = newConnection(); } catch (IOException e) { // connection failed, try again. try { Thread.sleep(1000); } catch (InterruptedException e) {}; establishConnection(); } }

I've solved this general problem with code similar to the above on many occasions, but I feel largely unsatisfied with the result. Is there a design pattern designed for dealing with this issue?

解决方案

One library worth checkout out is Sarge, which automatically performs retries according to a defined plan.
