创建两个springboot maven子项目

      子项目名称分别为order-server和user-server

配置user-server子项目：

     所需依赖：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId>
</dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId>
</dependency><!--mybatis-->
<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId>
</dependency>

     数据库表数据：

   

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;-- ----------------------------
-- Table structure for tb_user
-- ----------------------------
DROP TABLE IF EXISTS `tb_user`;
CREATE TABLE `tb_user`  (`id` bigint(20) NOT NULL AUTO_INCREMENT,`username` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '收件人',`address` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '地址',PRIMARY KEY (`id`) USING BTREE,UNIQUE INDEX `username`(`username`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 109 CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Compact;-- ----------------------------
-- Records of tb_user
-- ----------------------------
INSERT INTO `tb_user` VALUES (1, '柳岩', '湖南省衡阳市');
INSERT INTO `tb_user` VALUES (2, '文二狗', '陕西省西安市');
INSERT INTO `tb_user` VALUES (3, '华沉鱼', '湖北省十堰市');
INSERT INTO `tb_user` VALUES (4, '张必沉', '天津市');
INSERT INTO `tb_user` VALUES (5, '郑爽爽', '辽宁省沈阳市大东区');
INSERT INTO `tb_user` VALUES (6, '范兵兵', '山东省青岛市');SET FOREIGN_KEY_CHECKS = 1;
