Spring Cloud Eureka 服务治理学习2 注册服务提供者


一、操作

1. pom

<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
            <version>1.4.7.RELEASE</version>
        </dependency>
          <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
</dependencies>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR6</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2. 入口类

import de.codecentric.boot.admin.server.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**

 */
@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@EnableAdminServer
@SpringBootApplication
@EnableDiscoveryClient
public class SpringBootAdminApplication  {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootAdminApplication .class, args);
    }
}

3. 配置文件

eureka:
  client:
    registryFetchIntervalSeconds: 5
    service-url:
      defaultZone: http://eureka服务端ip:eureka端口号/eureka/
  instance:
    prefer-ip-address: true
    ip-address: 服务提供者ip
    non-secure-port: 服务提供者端口
    instance-id: 实例名称
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health

二、启动效果

三、安全验证

给服务端的pom.xml加上安全设置：

spring:
   security:
      user:
         name: admin
         password: 123456

这时登陆注册中心就需要输入用户名密码，客户端也需要加入相应配置：

eureka:
  instance:
    prefer-ip-address: true
  client:
    serviceUrl:
      defaultZone: http://admin:123456@eureka server ip:8761/eureka/

没配置用户名密码的话，启动时会报401错误。
