Springboot2.0 +Zuul Eureka Feign整合

版本说明：

springboot:2.2.2.RELEASE

jdk:1.8

由于使用的是springCloud的eureka，会存在springboot和springcloud版本不兼容

<dependencyManagement>
       <dependencies>
           <dependency>
               <groupId>org.springframework.cloud</groupId>
               <artifactId>spring-cloud-dependencies</artifactId>
               <version>Hoxton.RELEASE</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
       </dependencies>
   </dependencyManagement>

1.创建Eureka 注册中心

导入eureka 依赖包

<dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
       </dependency>

application.yml文件配置

server:port:3000

eureka:
instance:
hostname: localhost
client:
register-with-eureka: false
fetch-registry: false
serviceUrl:
default-zone: http://${eureka.instance.hostname}:${server.port}/eureka
server:
eviction-interval-timer-in-ms: 5000

在启动类上加上@EnableEurekaServer注解

启动服务后访问：http://localhost:3000/eureka ,可以看到

Springboot2.0 +Zuul Eureka Feign整合

由于还没有客户端注册进来，所以这里是空的

2.Zuul网关服务

添加依赖

<dependency>
           <groupId>org.springframework.cloud</groupId>
           <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
       </dependency>

       <dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
       </dependency>

application.yml

eureka:
instance:
instance_id: gateway
client:
service-url:
defaultZone: http://localhost:3000/eureka/

配置服务路由地址 application.properties 文件

server.port=8080
spring.application.name=gateway

#所有以/a/**开头的服务会进到demoA服务

zuul.routes.demoA.path=/a/**
zuul.routes.demoA.serviceId=demoA
zuul.routes.demoA.stripPrefix=false

#同上

zuul.routes.demoC.path=/c/**
zuul.routes.demoC.serviceId=demoC
zuul.routes.demoC.stripPrefix=false

zuul.host.connect-timeout-millis=4000
zuul.host.socket-timeout-millis=2000

启动类上加入一**解

@EnableZuulProxy
@EnableEurekaClient

Springboot2.0 +Zuul Eureka Feign整合

3.创建客户端demoA和demoC

添加依赖pom.xml

<dependency>
       <groupId>org.springframework.cloud</groupId>
       <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
       </dependency>

application.yml文件

server:port:8081

spring.application.name:demoA

eureka:
instance:
instance-id: ${spring.cloud.client.hostname}:${server.port}
client:
service-url:
defaultZone: http://localhost:3000/eureka/

在启动类上添加@EnableEurekaClient注解

创建controller

@RestController
@RequestMapping
public class AController {

   @GetMapping("/testA")
   public void test(){
       System.err.println("demoA");
   }
}

创建和demoA一样的demoC

demoC端口8082

4个服务都启动后

通过

http://localhost:8080/a/testA 就可以请求到demoA中的接口了

同理demoC ，http://localhost:8080/c/testC

初次搭建，各位大佬多指教
