//Create resttemplate
RestTemplate restTemplate = new RestTemplate(getClientHttpRequestFactory());
 
//Override timeouts in request factory
private SimpleClientHttpRequestFactory getClientHttpRequestFactory()
{
    SimpleClientHttpRequestFactory clientHttpRequestFactory = new SimpleClientHttpRequestFactory();
    // or 
    // HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory();
    
    //Connect timeout
    clientHttpRequestFactory.setConnectTimeout(10_000);
     
    //Read timeout
    clientHttpRequestFactory.setReadTimeout(10_000);
    return clientHttpRequestFactory;
}		
			
			

注意下面使用了 Java 11 語法 var factory = new SimpleClientHttpRequestFactory();

			
package cn.netkiller.consul.consumer;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

@Configuration
public class RestTemplateConfiguration {

	@Bean
	public RestTemplate restTemplate() {

		var factory = new SimpleClientHttpRequestFactory();

		factory.setConnectTimeout(3000);
		factory.setReadTimeout(3000);

		return new RestTemplate(factory);
	}
}
