1.RestTemplate超时
设置配置HttpComponentsClientHttpRequestFactory中的RequestConfig属性
RestTemplateConfig：
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;
/**
* Created by qhong on 2018/9/10 17:53
**/
@Slf4j
@Configuration
public class RestTemplateConfig {
@Bean
@ConfigurationProperties(prefix = "rest.connection")
public HttpComponentsClientHttpRequestFactory httpRequestFactory() {
return new HttpComponentsClientHttpRequestFactory();
}
@Bean
public RestTemplate customRestTemplate(){
return new RestTemplate(httpRequestFactory());
}
}
application.properties:
#restTemplate配置
rest.connection.connectionRequestTimeout=30000
rest.connection.connectTimeout=30000
rest.connection.readTimeout=30000
或者：
#restTemplate配置
rest.connection.connection-request-timeout=30000
rest.connection.connect-timeout=30000
rest.connection.read-timeout=30000
上面这两种格式的配置都可以。
