SpringBoot學習8.2-創建eureka服務治理節點

1.maven依賴

創建eureka服務治理節點主要依賴eureka-server。

注意：springboot和springcloud的版本關聯比較嚴格，此處使用的是springboot-2.0.0.RELEASE、springcloud-Finchley.RELEASE。

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.0.0.RELEASE</version>
	<relativePath /> <!-- lookup parent from repository -->
</parent>

......

<properties>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
	<java.version>1.8</java.version>
	<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
</properties>

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

<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>

<!-- maven install生成可運行的jar（工程內要有main方法），否則是一個普通jar -->
<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>
	</plugins>
</build>

2.spring配置文件

server:
  port: 7001 # 服務器端口
eureka:
  instance:
    hostname: localhost # Eureka註冊服務器名稱
  client:
    fetch-registry: false # 是否檢索服務
    register-with-eureka: false # 是否註冊給服務中心
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/ # 治理客戶端服務域

3.開啓eureka服務

@SpringBootApplication
@EnableEurekaServer // 啓動eureka服務端
public class EurekaServerApplication {
	public static void main(String[] args) {
		SpringApplication.run(EurekaServerApplication.class, args);
		System.out.println("eureka服務啓動完成！");
	}
}

4.啓動工程，訪問服務治理中心
