springcloud-服務提供與註冊Eureka

1. eureka_server

引入pom的依賴文件

<!--監控所需的接口-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!-- 引入eureka 的server依賴 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
<!-- 引入安全認證 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</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>

配置application.properties文件

server.port=8761

配置安全認證
security.basic.enabled=true
security.user.name=chuk
security.user.password=123456

配置eureka
不註冊自己
eureka.client.register-with-eureka=false
不檢索服務
eureka.client.fetch-registry=false
註冊地址
eureka.client.service-url.defaultZone=http://chuk:123456@localhost:8761/eureka

服務端主程序

//註冊中心
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

2. eureka_client

加入eureka客戶端的依賴

<!-- 加入eureka的客戶端 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>

配置properties文件

server.port=8887

spring.application.name=spring_cloud_movie

logging.level.root=info
logging.level.org.org.hibernate=info
logging.level.com.com.chukun=debug

註冊中心的地址
eureka.client.service-url.defaultZone=http://chuk:123456@localhost:8761/eureka/
顯示ip
eureka.instance.prefer-ip-address=true

顯示服務的實例id
eureka.instance.instance-id=${spring.application.name}:${spring.application.instance_id:${server.port}}

客戶端主程序

@SpringBootApplication
//提供服務
@EnableEurekaClient
public class SpringCloudMovieApplication {

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }

    public static void main(String[] args) {
        SpringApplication.run(SpringCloudMovieApplication.class, args);
    }
}

啓動註冊中心，與服務的提供者，就會向註冊中心註冊服務

運行結果如下
