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 客户端设置和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从默认的 300 毫秒更改 restTemplate 读取或连接超时。
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
..
}
}`
使用 application.properties 包含:
spring:

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?文档在这个主题上非常简单,似乎最近的代码甚至允许将 restTemplate 用于功能区/尤里卡弹簧启动默认值。也许这还没有建成。
