SpringCloud学习系列-Eureka服务注册与发现(3)

修改microservicecloud-provider-dept-8001

1.修改pom

增加内容

  <!-- 将微服务provider侧注册进eureka -->

   <dependency>

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

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

   </dependency>

   <dependency>

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

2修改yml

修改内容

eureka:

  client: #客户端注册进eureka服务列表内

    service-url:

      defaultZone: http://localhost:7001/eureka

完整内容

server:

  port: 8001

mybatis:

  config-location: classpath:mybatis/mybatis.cfg.xml        # mybatis配置文件所在路径

  type-aliases-package: com.atguigu.springcloud.entities    # 所有Entity别名类所在包

  mapper-locations:

  - classpath:mybatis/mapper/**/*.xml                       # mapper映射文件

spring:

   application:

    name: microservicecloud-dept

   datasource:

    type: com.alibaba.druid.pool.DruidDataSource            # 当前数据源操作类型

    driver-class-name: org.gjt.mm.mysql.Driver              # mysql驱动包

    url: jdbc:mysql://localhost:3306/cloudDB01              # 数据库名称

    username: root

    password: 123456

    dbcp2:

      min-idle: 5                                           # 数据库连接池的最小维持连接数

      initial-size: 5                                       # 初始化连接数

      max-total: 5                                          # 最大连接数

      max-wait-millis: 200                                  # 等待连接获取的最大超时时间

eureka:

  client: #客户端注册进eureka服务列表内

    service-url:

      defaultZone: http://localhost:7001/eureka      

3.DeptProvider8001_App主启动类

package com.atguigu.springcloud;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

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

@SpringBootApplication

@EnableEurekaClient //本服务启动后会自动注册进eureka服务中

public class DeptProvider8001_App

{

  public static void main(String[] args)

  {

   SpringApplication.run(DeptProvider8001_App.class, args);

  }

}

4.测试

先要启动EurekaServer

http://localhost:7001/
