SpringCloud配置文件中的坑

com.sun.jersey.api.client.ClientHandlerException: java.net.ConnectException: Connection refused: connect问题

 

版本springcloud 2.1.2

此处本地测试用的单注册中心

eureka配置

采用 .yml 配置方式

# 单例配置
spring:
  application:
    name: arisgo-eureka
server:
  port: 8890
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      default-zone: http://localhost:8890/eureka/

此处注册中心配置的端口号为8890，注册中心指定地址为  http://localhost:8890/eureka

服务提供者配置

eureka:
  client:
    service-url:
      default-zone: http://localhost:8890/eureka/
  instance:
    lease-renewal-interval-in-seconds: 2
    lease-expiration-duration-in-seconds: 4
spring:
  application:
    name: service-user
server:
  port: 8791

启动服务提供者时报错如下：

问题描述：连接不到地址为 http://localhost:8761/eureka 的注册中心

原因：服务中指定的 http://localhost:8890/eureka 注册中心地址无效，而用了springcloud默认的注册中心地址

修改服务中的配置文件属性 default-zone为defaultZone

尝试了几次：服务提供者配置文件中default-zone属性识别不到，只能识别defaultZone

结论：配置文件中还是以 “驼峰法” 命名较好，不然谁知道下一个坑你会踩在哪里......
