问题描述
我已经使用 spring-cloud 构建了一个 spring boot 应用程序,并希望在我的客户端应用程序(这也是一个微服务)中使用 RestTemplate,以便我可以继续使用 mockMvc 进行集成测试.我正在使用默认的ribbon/eureka/hystrix客户端设置以及我正在调用的服务中的客户端微服务和eureka客户端.这是有效的(一旦我发现 serviceIds 是在 restTemplate 中标识服务端点的东西).我的问题是我似乎无法将 restTemplate 读取或连接超时从似乎默认的 300 毫秒更改.
I have built a spring boot application using spring-cloud and want to use RestTemplate within my client application (which is also a microservice) so that I can continue using mockMvc for integration testing. I am a using the default ribbon/eureka/hystrix client setup with my client microservice and eureka client within the service I'm calling. This is working (once I figured out that serviceIds are what identifies a service endpoint within restTemplate). My problem is that I cant seem to change the restTemplate read nor connection timeout from what seems like a default of 300ms.
通话详情:
`@Configuration
@EnableAutoConfiguration
@ComponentScan
@EnableConfigurationProperties
@EnableHystrix
@EnableEurekaClient
public class Application { ... public static void main(String[] args) {} ... }
@Component
class EricComponentToDoHystrix { // apparently this has to be a component for hystrix to work btw
@Autowired
RestTemplate restTemplate;
..
@HystrixCommand(fallbackMethod="defaultRestTemplateCall")
public void doRestTemplateCall()
ResponseEntity<String> result = restTemplate.getForEntity("http://someservice/doSomething", String.class); // actually make a call
..
}
}`
一个 application.properties 包含:
with an application.properties containing:
spring:
cloud:
client:
serviceIds:
- someservice
someservice:
ribbon:
#listOfServers: localhost:7080
#NIWSServerListClassName: com.netflix.niws.loadbalancer.DiscoveryEnabledNIWSServerList
# the eureka vipAddress of the target service (Disabled)
DeploymentContextBasedVipAddresses: someservice
# Interval to refresh the server list from the source
ServerListRefreshInterval: 1000
# Connect timeout used by Apache HttpClient.. apparently not by restTemplate
ConnectTimeout: 30000
# Read timeout used by Apache HttpClient.. apparently not by restTemplate
ReadTimeout: 30000
eureka:
client:
#Region where eureka is deployed -For AWS specify one of the AWS regions, for other datacenters specify a arbitrary string
#indicating the region.This is normally specified as a -D option (eg) -Deureka.region=us-east-1
region: default
#For eureka clients running in eureka server, it needs to connect to servers in other zones
preferSameZone: false
us-east-1:
availabilityZones: default
instance:
#Virtual host name by which the clients identifies this service
virtualHostName: ${spring.application.name}
appGroupName: ericGroup
# disable Ribbon's cicruit breaker and rely soley on Hystrix.
# this helps to avoid confusion.

有人知道我需要什么属性来修改restTemplate的默认超时吗?关于这个主题的文档非常简单,似乎最近的代码甚至允许针对ribbon/eureka spring boot默认值使用restTemplate.也许这还没有建成.
Anybody know what properties I need so set to modify restTemplate's default timeouts? Documentation is very light on this subject and it seems the code just recently even allowed restTemplate to be used against ribbon/eureka spring boot defaults. Perhaps this has not been built yet.
推荐答案
你正在注入的 RestTemplate
完全是普通的,除了一个 RibbonInterceptor
选择物理主机您的 URI(请参阅 https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-core/src/main/java/org/springframework/cloud/netflix/ribbon/RibbonAutoConfiguration.java).超时和其他属性通过 ClientHttpRequest
在 RestTemplate
中控制.您可能应该将 RibbonInterceptor
注入您自己的 RestTemplate
并设置一个 ClientHttpRequestFactory
来执行超时,例如
The RestTemplate
you are injecting is completely vanilla except for a RibbonInterceptor
that chooses the physical host in the URI for you (see https://github.com/spring-cloud/spring-cloud-netflix/blob/master/spring-cloud-netflix-core/src/main/java/org/springframework/cloud/netflix/ribbon/RibbonAutoConfiguration.java). The timeouts and other properties are controlled in the RestTemplate
through the ClientHttpRequest
. You probably should just inject the RibbonInterceptor
into your own RestTemplate
and set up a ClientHttpRequestFactory
to do the timeouts, e.g.
@Component
class EricComponentToDoHystrix {
private RestTemplate restTemplate;
@Autowired
public EricComponentToDoHystrix(RibbonInterceptor interceptor) {
restTemplate = new RestTemplate();
restTemplate.setInterceptors(Arrays.asList(interceptor));
restTemplate.setRequestFactory(...);
}
}
