微服務分佈式事務實戰（三）SpringCloud註冊中心編寫和測試

SpringCloud註冊中心編寫和測試
（1）創建註冊中心工程

（2）添加jar包 pom.xml

 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <groupId>com.jh</groupId>
      <artifactId>RegisterCenter </artifactId>
      <version>0.0.1-SNAPSHOT</version>
      <packaging>jar</packaging>
    
      <name> RegisterCenter </name>
      <url>http://maven.apache.org</url>
      
      <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      </properties>

  
<!--  1 spring boot parent  -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.3.RELEASE</version>
        <relativePath/>
    </parent>
       <!-- spring    -->

    <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
   
         <!--2 註冊服務中心   -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <!-- spring  boot 測試 -->
       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency> 
                 
   <!-- spring cloud  依賴版本 -->

      </dependencies>
         <dependencyManagement>
            <dependencies>
                <dependency>
                    <groupId>org.springframework.cloud</groupId>
                    <artifactId>spring-cloud-dependencies</artifactId>
                    <version>Dalston.SR3</version>
                    <type>pom</type>
                    <scope>import</scope>
                </dependency>
            </dependencies>
        </dependencyManagement>
    </project>

（3） 編寫主程序

@EnableEurekaServer // 開啓註冊發現
@SpringBootApplication // spring boot應用程序
public class EurekaServer {
	public static void main(String[] args) {
		SpringApplication.run(EurekaServer.class, args);
	}
}

（4）配置文件application.properties

server.port=8001
eureka.instance.hostname=localhost
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
eureka.client.service-url.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

（5）測試：

 打開瀏覽器輸入http://loclalhost:8001
 系統返回
