搭建服务注册中心

创建一个maven工程,做为注册中心,引入pom依赖

   <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>
    <!-- 管理依赖 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.M7</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <!--SpringCloud eureka-server -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>
    <!-- 注意： 这里必须要添加， 否者各种依赖有问题 -->
    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

配置application.yml文件

###服务启动端口号
server:
  port: 8100

##定义服务名称
spring:
  application:
    name: com.songzixian

###服务注册名称
eureka:
  instance:
    hostname: 127.0.0.1

  ###客户端调用地址
  client:
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:8001/eureka/


    ###因为该应用为注册中心，需要将服务注册到注册中心(集群的时候需要为true)
    register-with-eureka: true

    ###因为改应用为注册中心,不需要检索服务信息
    fetch-registry: true

启动Eureka服务

@EnableEurekaServer
@SpringBootApplication
public class AppEureka1 {

    public static void main(String[] args) {
        SpringApplication.run(AppEureka1.class,args);
    }
}

搭建服务消费者

创建一个maven工程,做为服务的消费者,引入pom文件

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.1.RELEASE</version>
</parent>
<!-- 管理依赖 -->
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Finchley.M7</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
<dependencies>
    <!-- SpringBoot整合Web组件 -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- SpringBoot整合eureka客户端 -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>

</dependencies>
<!-- 注意： 这里必须要添加， 否者各种依赖有问题 -->
<repositories>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/libs-milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

配置application.yml文件

###服务启动端口号
server:
  port: 8001
###服务名称(服务注册到eureka名称)
spring:
  application:
    name: com.songzixian
###服务注册到eureka地址
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8100/eureka


    ###因为该应用为注册中心，不会注册自己
    register-with-eureka: true
    ###是否需要从eureka上获取注册信息
    fetch-registry: true

创建一个测试类

    @RestController
    public class TestMabber {
    
        @RequestMapping("testMabber")
        public String testMabber(){
    
            System.out.println("com.songzixian");
            return "办法执行了";
        }
    }

启动服务

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