Setting timeouts in Spring Rest Template
提问by Sajal Saxena
Application is using Spring rest template to call a webservice and i am using
restTemplate.exchage(url) to call the webservice.
Currently we are not passing any timeout value for this webservice call, How can i set a timeout value for Spring Rest template.
应用程序使用 Spring rest 模板来调用 webservice，我使用
restTemplate.exchage(url) 来调用 webservice。目前我们没有为此 Web 服务调用传递任何超时值，如何为 Spring Rest 模板设置超时值。

You can use code similar to following for setting connection timeout:
您可以使用类似于以下的代码来设置连接超时：
RestTemplate restTemplate = new RestTemplate();
((SimpleClientHttpRequestFactory)restTemplate.getRequestFactory()).setConnectTimeout(2000);
If your wish to set read timeout, you can have code similar to following:
如果您希望设置读取超时，您可以使用类似于以下的代码：
((SimpleClientHttpRequestFactory)restTemplate.getRequestFactory()).setReadTimeout(2000);
The time is given in milliseconds here. For more info, you can visit the documentation page.

I use this approach based on these threads
我使用基于这些线程的这种方法
int DEFAULT_TIMEOUT = 5000;
RequestConfig requestConfig = RequestConfig.custom()
.setConnectTimeout(DEFAULT_TIMEOUT)
.setConnectionRequestTimeout(DEFAULT_TIMEOUT)
.setSocketTimeout(DEFAULT_TIMEOUT)
.build();
CloseableHttpClient httpClient = HttpClients.custom()
.setDefaultRequestConfig(requestConfig)
.build();
CloseableHttpClient httpClient = HttpClients.custom()
.setDefaultRequestConfig(requestConfig)
.build();
Spring RestTemplate Connection Timeout is not working
Java : HttpClient 4.1.2 : ConnectionTimeout, SocketTimeout values set are not effective
Java : HttpClient 4.1.2 : ConnectionTimeout、SocketTimeout 值设置无效

RestTemplateBuilder introduced since Spring 1.4 could be used to set read and connect timeout settings for RestTemplate object. Here is sample code -
从 Spring 1.4 开始引入的 RestTemplateBuilder 可用于为 RestTemplate 对象设置读取和连接超时设置。这是示例代码 -
final RestTemplate restTemplate =
new RestTemplateBuilder()
.setConnectTimeout(Duration.ofMillis(connectTimeoutMillis))
.setReadTimeout(Duration.ofMillis(readTimeoutMillis))
.build();
