SpringCloud——服务注册中心Eureka搭建

Spring-Cloud之服务注册中心Eureka

注册中心是一个特殊作用Spring Boot应用。所以我们先到官网生成一个Spring Boot应用。我自己使用的1.5.9这个版本。

添加对Spring Cloud依赖包：

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

pom.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </dependency>
        </dependencies>
    </dependencyManagement>

        </dependency>


        <!--spring-cloud-->

            <artifactId>spring-cloud-starter</artifactId>
        </dependency>

        </dependency>




    </dependencies>

    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
    </repositories>
</project>

3 在启动类上添加注解@EnableEurekaServer，启动eureka功能：

@SpringBootApplication
@EnableEurekaServer
public class SpringCloudTestApplication {

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

4 设置配置文件

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

默认eureka自己也会当作客户端注册到eureka注册中心上，我们设置registerWithEureka为false,关闭该功能。
5 启动应用，访问8761端口：
这里写图片描述
我们看到注册中心已经可以启动了，但是没有任何服务注册到此。接下来就需要我们写服务者和消费者了。
