我有Spring Cloud的微服务项目,来自父母的片段:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.7.RELEASE</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR3</version>
<type>pom</type>
<scope>import</scope>
</dependency>
所有服务都在Eureka服务器下运行:
所有服务都运行良好.我可以打电话给Postman打电话,一切正常.
我有单独的服务处理Hystrix仪表板,一个来自pom的片段:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
</dependency>
配置主类:
@SpringBootApplication
@EnableHystrixDashboard
public class DashboardApp {
public static void main(String[] args) {
SpringApplication.run(DashboardApp.class, args);
}
}
和配置yaml文件:
spring:
application:
name: Dashboard
server:
port: 8000
eureka:
client:
fetchRegistry: true
registerWithEureka: false
serviceUrl:
defaultZone: http://localhost:8761/eureka
我有下一个仪表板看:
来自控制台的完整堆栈跟踪是here.以下是一些片段:
2018-04-12 11:28:25.089 ERROR 15762 --- [qtp295055909-16] ashboardConfiguration$ProxyStreamServlet : Error proxying request: http://localhost:8082/hystrix.stream
java.lang.RuntimeException: org.eclipse.jetty.io.EofException

....
Caused by: org.eclipse.jetty.io.EofException: null
...
Caused by: java.io.IOException: Broken pipe
...
弹簧执行器可以进行维修:
它的片段是pom:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
Config类看起来:
@EnableHystrix
@EnableEurekaClient
@SpringBootApplication
public class TableApp {
public static void main(String[] args) {
SpringApplication.run(TableApp.class, args);
}
}
如何解决这个问题?
解决方法:
对于使用spring boot 2的用户,hystrix.stream端点已移至/actuator/hystrix.stream.
对我来说,这个网址有效:
http://localhost:8082/actuator/hystrix.stream
是的,通过以下属性启用此执行器端点:
management.endpoints.web.exposure.include=hystrix.stream
当然,您必须在项目中包含actutator依赖项.
