服务发现与注册-Eureka

1.搭建

创建一个Springboot项目，添加依赖

<dependencies>
  <!--添加Eureka服务器端依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
</dependencies>

 <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

application.yml中添加配置

spring:
    application:
        name: eureka-server
server:
    port: 8003
eureka:
    instance:
        hostname: localhost
    client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
            defaultZone: http://${eureka.instance.name}:${server.port}    

启动项目，浏览器中打开如下：

2.注册服务

创建另一个服务，添加依赖

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

 <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

bootstrap.yml中添加配置

spring:
    application:
        name: oauth2
eureka:
    client:
        serviceUrl:
            defaultZone: http://localhost:8003/eureka
