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
 *  注解生效激活 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  
    *.hprof;*.idea;*.iml;*.pyc;*.pyo;*.rbc;*.yarb;*~;.DS\_Store;.git;.hg;.svn;CVS;**pycache**;\_svn;vssver.scc;vssver2.scc;

--------------------

1.新建maven项目:demo2020  
2.改pom

                </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
