//表示服务注册中心

@EnableEurekaServer

@SpringBootApplication

public class EurekaApplication {

public static void main(String[] args) {

SpringApplication.run(EurekaApplication.class,args);

}

}

3. yml 配置

server:

port: 7001

spring:

application:

name: cloud-eureka-service

eureka:

instance:

hostname: eureka7001

client:

#false 表示不向注册中心注册自己

register-with-eureka: false

#false 表示自己就是注册中心，我的职责是维护服务实例，并不需要去检索服务

fetch-registry: false

service-url:

#设置与 eureka server 交互的地址查询服务和注册服务都依赖这个地址

defaultZone: http://$eureka.instance.hostname:${server.port}/eureka/

4. 测试

三、Eureka Server 集群部署

======================================================================================

1. pom 依赖引用(和单机版一致)

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-actuator</artifactId>

</dependency>

2. 配置启动类

//eureka-7001

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

//表示服务注册中心

@EnableEurekaServer

@SpringBootApplication

public class EurekaApplication {

public static void main(String[] args) {

SpringApplication.run(EurekaApplication.class,args);

}

}

//eureka-7002

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

//表示服务注册中心

@EnableEurekaServer

@SpringBootApplication

public class EurekaApplication {

public static void main(String[] args) {

SpringApplication.run(EurekaApplication.class,args);

}

}

3. yml 配置

7001

server:

port: 7001

spring:

application:

name: cloud-eureka-service

eureka:

instance:

hostname: eureka7001

client:

#false 表示不向注册中心注册自己

register-with-eureka: false

#false 表示自己就是注册中心，我的职责是维护服务实例，并不需要去检索服务

fetch-registry: false

service-url:

#设置与 eureka server 交互的地址查询服务和注册服务都依赖这个地址

defaultZone: http://eureka7002:7002/eureka/

7002

server:

port: 7002

spring:

application:

name: cloud-eureka-service

eureka:

instance:

hostname: eureka7002

client:

#false 表示不向注册中心注册自己

register-with-eureka: false

#false 表示自己就是注册中心，我的职责是维护服务实例，并不需要去检索服务

fetch-registry: false

service-url:

#设置与 eureka server 交互的地址查询服务和注册服务都依赖这个地址

defaultZone: http://eureka7001:7001/eureka/

4. 测试

四、Eureka client 部署（服务消费者和服务提供者）

=================================================================================================

1. pom 依赖引入

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-actuator</artifactId>

</dependency>

2. 配置主启动类

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@EnableEurekaClient

@SpringBootApplication

public class PaymentApplication {

public static void main(String[] args) {

SpringApplication.run(PaymentApplication.class,args);

}

}

3. yml 配置

server:

port: 8888

eureka:

cli

ent:

register-with-eureka: true

fetch-registry: true

service-url:

defaultZone: http://eureka7001:7001/eureka,http://eureka7002:7002/eureka

instance:

prefer-ip-address: true

instance-id: payment-8888

4. 测试

五、配置 actuator 信息

=================================================================================

eureka:

client:

register-with-eureka: true

fetch-registry: true

service-url:

defaultZone: http://eureka7001:7001/eureka,http://eureka7002:7002/eureka

instance:

prefer-ip-address: true #显示主机 ip 名称

instance-id: payment-8888 #实例 id

management:

endpoint:

health:

show-details: always #显示详细信息

endpoints:

web:

exposure:

exclude: env #排除 actuator 暴露的接口

include: ["health","info","mappings"] #设置暴露的 actuator 接口
