如果响应花费太长，请取消休息请求

Question

我想取消响应时间超过3秒，但我尚未设法弄清楚如何做。

所以说我有一个线程A：

@Override
public void run() {
    RestTemplate restTemplate = new RestTemplate();
    IsAliveMessage isAliveMessage = new IsAliveMessage(nodeInfo.getHostname(), nodeInfo.getPort());
    IsAliveResponse isAliveResponse = restTemplate.postForObject(
        "http://" + nodeInfo.getHostname() + ":" + nodeInfo.getPort() + "/node/isAlive",
         isAliveMessage,
         IsAliveResponse.class);
}

提出请求并期望B：

的答案

@RequestMapping( value="/isAlive", method= RequestMethod.POST)
    public IsAliveResponse isAlive() throws ConnectException {
        try {
            Thread.sleep(100000);
            IsAliveResponse response = new IsAliveResponse("here here!" ,true);
            return response;
        } catch (Exception e) {
            Thread.currentThread().interrupt();
    }
}

b"睡觉"，没有回答，但是A一直在等待该答案。在一定时间跨度之后，我该如何放弃等待？

预先感谢

您可以配置rettemplate等待三秒钟的响应：

RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());
private ClientHttpRequestFactory getClientHttpRequestFactory() {
    int timeout = 3000;
    HttpComponentsClientHttpRequestFactory clientHttpRequestFactory =
    new HttpComponentsClientHttpRequestFactory();
    clientHttpRequestFactory.setConnectTimeout(timeout);
    clientHttpRequestFactory.setReadTimeout(timeout);
    return clientHttpRequestFactory;
}
