Question

我的应用程序使用Spring集成与第三方系统进行通信。我发送一个有效载荷，对此，我得到了解析和使用的响应。都好。请在下面使用我使用的SI xml。

现在，我想在异常情况下（尝试连接的服务器不可用，超时或拒绝连接等）重新尝试建立连接。如何使用SI xml配置实现此目标？请指导。

您可以将retry-advice添加到您的<int-ip:tcp-outbound-gateway>中：

<int-ip:tcp-outbound-gateway>
    <int-ip:request-handler-advice-chain>
        <int:retry-advice/>
    </int-ip:request-handler-advice-chain>
</int-ip:tcp-outbound-gateway>
