- 我在使用eureka client消费者调用生产者的时候,出现以下问题:
java.lang.IllegalStateException: No instances available for eureka-server
就是 eureka-server服务不可用
- 我的配置如下
服务注册中心配置:
server:
port: 8760
spring:
application:
name: eureka-server
eureka:
instance:
hostname: 127.0.0.1
prefer-ip-address: true
client:
service-url:
defaultZone: http://${eureka.instance.hostname}:8760/eureka
register-with-eureka: false
fetch-registry: false
生产者配置:
server:
port: 8761
spring:
application:
name: eureka-service
eureka:
instance:
hostname: localhost
client:
service-url:
defaultZone: http://${eureka.instance.hostname}:8760/eureka
消费者配置:
server:
port: 8762
spring:
application:
name: eureka-consumer
eureka:
instance:
hostname: localhost
client:
service-url:
defaultZone: http://${eureka.instance.hostname}:8760/eureka
- 出现“No instances available for eureka-server”原因及解决办法
由于netflix-eureka-client中已经集成了ribbon,所以导包的时候只要netflix-eureka-client这个就可以了。
这是我导入的依赖:
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
<version>2.2.9.RELEASE</version>
</dependency>
去掉netflix-ribbon依赖即可解决问题
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
