微服务spring-cloud day1

参考:https://blog.csdn.net/moshowgame/article/details/80633969

git项目地址:https://gitee.com/zyf6303/spring-cloud-study

一.创建spring-cloud父工程

这里使用的工具是Spring Tool Suite 4 

创建一个maven project 

 

 二.引入依赖

1.父工程pom依赖:

三.配置:

1.center:

server:
  port: 8080
spring:
  application:
    name: EUREKA-CENTER
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/

2.router:

server:
  port: 8081
  
spring:
  application:
    name: zuul
    
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/
zuul:
    routes:
     apis1:
      path: /api1/**
      #serviceId: spring-cloud-study-demo
      serviceId: SPRING-CLOUD-PLOYMER-DEMO
     apis2:
      path: /api2/**
      url: http://127.0.0.1:8082/

3.demo

server:
  port: 8082
  servlet:
      context-path: /demo
tomcat:
    remote-ip-header: x-forward-for
    uri-encoding: UTF-8
    max-threads: 10
    background-processor-delay: 30
spring:
    http:
      encoding:
        force: true
        charset: UTF-8
    application:
        name: spring-cloud-ploymer-demo
    freemarker:
        request-context-attribute: req
        #prefix: /templates/
        suffix: .html
        content-type: text/html
        enabled: true
        cache: false
        charset: UTF-8
        allow-request-override: false
        expose-request-attributes: true
        expose-session-attributes: true
        expose-spring-macro-helpers: true
        #template-loader-path: classpath:/templates/
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/
  instance:
    ip-address: ture

四.启动类

1.center

@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

2.router

@EnableZuulProxy
@EnableEurekaClient
@SpringBootApplication
public class ZuulApplication {
    public static void main(String[] args) {
        SpringApplication.run(ZuulApplication.class, args);
    }
}

3.demo

@EnableEurekaClient
@SpringBootApplication
public class CheckCollectSysApplication {
    public static void main(String[] args) {
        SpringApplication.run(CheckCollectSysApplication.class,args);
    }
}

五.编写测试接口

六.运行结果:
