017 Build eureka registration center

1 eureka server

    Create a maven project, and the pom file introduces dependencies:

	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka-server</artifactId>
		</dependency>
	</dependencies>
	
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-starter-parent</artifactId>
				<version>Camden.SR3</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

    Configuration file: application.yml

server:
  port: 8761
  
spring:
  application:
    name: eureka

eureka: 
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://localhost:${server.port}/eureka/

    Startup class:

@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
	public static void main(String[] args) {
		SpringApplication.run(EurekaApplication.class, args);
	}
}

    Start the project and visit: http://localhost:8761/

2 Registration service

    Based on the sales and user projects in the previous article, taking the user project as an example, the sales project is similar, and the following files are modified:

    2-1 Add pom dependencies

    <dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>
    </dependencies>
	
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-starter-parent</artifactId>
				<version>Camden.SR3</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

    2-2 update application.yml

server:
  port: 8081

spring:
  application:
    name: sales
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1/test?characterEncoding=UTF-8&useSSL=false
    username: root
    password: root
    
eureka:
  client:
    serviceUrl: 
      defaultZone: http://localhost:8761/eureka/
  instance:
    prefer-ip-address: true

# mybatis
mybatis:
  mapperLocations: classpath:mapper/*.xml

    2-3 Modify the startup class and add the @EnableDiscoveryClient annotation

@SpringBootApplication
@EnableDiscoveryClient
public class UserApplication {
	public static void main(String[] args) {
		SpringApplication.run(UserApplication.class, args);
	}
}

    2-4 Start the sales and user projects and visit: http://localhost:8761/
