Eureka服务器连接被拒绝，客户端org.springframework.beans.factory.UnsatisfiedDependencyException：
下面是有关使用Zuul Netflix Eureka的Spring boot microservices的一些教程。我有2个Eureka客户端连接到一个Eureka服务器，在Eureka服务器中也设置了Zuul代理。
我在github上发现了一个问题，但是，我一遍遍地遍历了Application.yml配置，只是看不到我在做什么错。
所有3个Spring Boot实例都运行相同的Spring Boot版本
POM.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.0.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
...
<spring-cloud.version>Greenwich.M1</spring-cloud.version>
</properties>
带有Zuul代理配置的Eureka服务器
spring:
application:
name: eureka-service
server:
port: 8302
eureka:
client:
registerWithEureka: false
fetchRegistry: false
server:
waitTimeInMsWhenSyncEmpty: 0
zuul:
#Service will be mapped under the /api URL
prefix: /api
routes:
db-service:
path: /db-service/**
url: http://localhost:8300
stock-service:
path: /stock-service/**
url: http://localhost:8301
Eureka客户端配置
spring:
application:
name: stock-service
server:
port: 8301
eureka:
client:
registerWithEureka: true
fetchRegistry: true
service-url:
defaultZone: http://localhost:8302/eureka/
instance:
hostname: localhost
我的Eureka信息中心成功显示2个已注册的应用程序
我能够通过Zuul代理访问我的REST端点
http://localhost:8302/api/db-service/rest/db/<name>但我仍然遇到这些错误。
问题 1.我想念我为什么要得到这些例外？ 2.任何麻烦的建议或工具...
只要服务器正在运行，我就会从服务器中获得以下循环异常。
