启动类配置

在启动类上面添加@EnableEurekaServer注解即可

yml配置

配置日志打印级别是为了阻止eureka心跳检测的日志输出

server:
  port: 1001
  servlet:
    context-path: /
spring:
  application:
    name: eureka-server
eureka:
  client:
    fetch-registry: false
    register-with-eureka: true
    service-url:
      defaultZone: http://localhost:1001/eureka/
  instance:
    hostname: localhost
  server:
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 10000

      discovery:

StripPrefix属性说明

StripPrefix作用是去掉部分URL路径，下面说明示例，网关端口为1004，原接口服务端口为1003，原接口实际请求路径为：http://localhost:1003/producer/test/blog/test

如果StripPrefix=2，path配置为如下

predicates:
            - Path=/**
          filters:
            - StripPrefix=2
1
2
3
4

则请求路径应该为http://localhost:1004///producer/test/blog/test，即你在端口路径后面任意添加两段前缀都可以访问到该接口，如果path配置为如下

predicates:
            - Path=/api/producer-develop/**
          filters:
            - StripPrefix=2
1

则请求路径应该为http://localhost:1004/api/producer-develop/producer/test/blog/test,即前缀必须是api/producer-develop，就是配置文件里面指定的。
