SpringBoot学习8.2-创建eureka服务治理节点

1.maven依赖

创建eureka服务治理节点主要依赖eureka-server。

注意：springboot和springcloud的版本关联比较严格，此处使用的是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服务端 -->
<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生成可运行的jar（工程内要有main方法），否则是一个普通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 # 服务器端口
eureka:
  instance:
    hostname: localhost # Eureka注册服务器名称
  client:
    fetch-registry: false # 是否检索服务
    register-with-eureka: false # 是否注册给服务中心
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/ # 治理客户端服务域

3.开启eureka服务

@SpringBootApplication
@EnableEurekaServer // 启动eureka服务端
public class EurekaServerApplication {
	public static void main(String[] args) {
		SpringApplication.run(EurekaServerApplication.class, args);
		System.out.println("eureka服务启动完成！");
	}
}

4.启动工程，访问服务治理中心
