SpringBoot 超时设置

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。
