2019独角兽企业重金招聘Python工程师标准>>> 
初始化主项目
- 生成一个主maven项目
mvn archetype:generate -DgroupId=com.edurt.si -DartifactId=springcloud-integration -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false
-
删除生成文件中的src源码目录下的所有源码
-
修改pom.xml配置文件为以下内容
org.springframework.boot
spring-boot-starter-parent
2.0.3.RELEASE
4.0.0
com.edurt.si
springcloud-integration
pom
1.0.0
springcloud-integration
Finchley.RELEASE
org.springframework.cloud
spring-cloud-dependencies
${dependency.spring.cloud.common.version}
pom
import
- 将项目导入IDEA中
创建eureka子模块
- 创建一个springcloud-integration-eureka的子模块pom.xml文件如下
springcloud-integration
com.edurt.si
1.0.0
4.0.0
springcloud-integration-eureka
org.springframework.cloud
spring-cloud-starter-netflix-eureka-server
我们首先引入了spring-cloud-starter-netflix-eureka-server依赖,这样的话我们才能使用eureka服务.
此时的父pom.xml文件中的modules会变成以下内容
springcloud-integration-eureka
如果没有变化的话,手动将子模块名称加入进去即可.
- 创建一个java类用于做为程序的启动入口(SpringCloudIntegrationEurekaLaunch.java)

@SpringBootApplication
public class SpringCloudIntegrationEurekaLaunch {
public static void main(String[] args) {
SpringApplication.run(SpringCloudIntegrationEurekaLaunch.class, args);
}
}
此时该应用通过使用**@SpringBootApplication注解可以成为SpringBoot应用,我们将其转换为Eureka服务的话我们需要在@SpringBootApplication注解下增加@EnableEurekaServer**注解,这样我们的应用将成为Eureka Server,此时的最终代码为

- 启动服务浏览器打开http://localhost:8080出现以下画面
此页面为eureka服务的监控页面
System Status 显示系统的一些基本信息 DS Replicas 显示eureka服务的一些负载/备份信息 Instances currently registered with Eureka 显示注册到eureka的服务实例列表 General Info 当前eureka服务的一些基本信息 Instance Info 当前eureka服务的主机/健康信息
- 为了方便后期其他应用接入进来我们创建一个应用的配置文件
在resources资源目录下创建一个application.properties的配置文件,内容如下
# 服务端口
server.port=1000
我们只配置一下服务的端口,然后重启服务,浏览器打开http://localhost:1000即可看到eureka的监控页面.
- 服务启动时期会出现一个连接错误

这是因为我们无法连接eureka服务,你可能会问我们现在的程序就是eureka服务,为什么还会去连接其他的Eureka服务呢?这是因为在eureka源码中如果我们不设置eureka.client.register-with-eureka和eureka.client.fetch-registry这两个参数的话,那么这两个参数的默认值是true也就是说即使我们使用**@EnableEurekaServer注解标识我们的服务是eureka服务但他同时也是一个eureka client所以会去连接eureka服务,这个错误可以忽略,或者我们修改一下application.properties**配置文件内容如下
# 服务端口
server.port=1000
eureka.client.register-with-eureka=false
