这个没啥好说的代码也就那个几句，直接看运行效果。  
用到MySQL的数据库很简单就一个测试表：

/*
    Navicat MySQL Data Transfer
    Source Server         : 47.107.50.15
    Source Server Version : 50630
    Source Host           : 47.107.50.15:3306
    Source Database       : springcloudDB
    Target Server Type    : MYSQL
    Target Server Version : 50630
    File Encoding         : 65001
    Date: 2018-11-26 16:09:26
    */
    SET FOREIGN_KEY_CHECKS=0;
    -- ----------------------------
    -- Table structure for `t_student`
    -- ----------------------------
    DROP TABLE IF EXISTS `t_student`;
    CREATE TABLE `t_student` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `name` varchar(20) NOT NULL,
      `grade` varchar(20) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
    -- ----------------------------
    -- Records of t_student
    -- ----------------------------
    INSERT INTO `t_student` VALUES ('1', '小明', '三');

就一个用spring JPA做的简单的查询

配置如下：

server:
      port: 1001
      context-path: /
    # 数据源配置
    spring:
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.jdbc.Driver
        url: jdbc:mysql://47.107.50.15:3306/springcloudDB
        username: root
        password: lifuping0.
      jpa:
        hibernate:
          ddl-auto: update
        show-sql: true
    eureka:
      instance:
        hostname: localhost  #eureka客户端主机实例名称
        appname: springcloud-provider  #客户端服务名
        instance-id: springcloud-provider:1 #客户端实例名称
        prefer-ip-address: true #显示IP
      client: 
        service-url: 
          defaultZone: http://localhost:7001/eureka   #把服务注册到eureka注册中心

暴露服务到eureka服务注册中心
