springcloud学习-01 建父工程+idea设置（自己看的）【周阳springcloud2020学习笔记】

约定 > 配置 > 编码
开发步骤（实用）
    1）建module
    2）改pom
    3）写yml
    4）主启动
    5）业务类

idea设置

• 改字符编码 setting->editor->File Encodeing 全部修改成UTF-8
• 注解生效** setting->build…->compiler->annotation…->右侧 enable 勾上
• java编辑版本 setting->build…->compiler->java compliler 选1.8
• File Types过滤 setting->editor->File Types

1.新建maven项目:demo2020
2.改pom

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <!-- dependencyManagement 父工程同一版本:子模块继承之后，提供作用：锁定版本+子modlue不用写groupId和version -->
        <dependencyManagement>
            <dependencies>

                </plugin>
            </plugins>
        </build>

    </project>

3.maven跳过单元测试：右侧 Maven Projects 设置 【长得像闪电的那个图标选中即可】
父工程执行install发布到仓库，方便子类继承

4.建数据库、建表

/*
Source Server         : 本地 test
Source Server Version : 50622
Source Host           : localhost:3306
Source Database       : demo2020
*/
SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for payment
-- ----------------------------
DROP TABLE IF EXISTS `payment`;
CREATE TABLE `payment` (
  `id` bigint(20) NOT NULL COMMENT '主键',
  `serial` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of payment
-- ----------------------------
INSERT INTO `payment` VALUES ('1', '尚硅谷');
INSERT INTO `payment` VALUES ('2', 'alibaba');
INSERT INTO `payment` VALUES ('3', '京东');
INSERT INTO `payment` VALUES ('4', '头条');

5.子模块开始…见代码咯
