a.建立數據庫 springbootdb:html

DROP TABLE IF EXISTS `city`;
CREATE TABLE `city` (
`
id
` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT
'城市編號'
,
`province_id` int(10) unsigned NOT NULL COMMENT
'省份編號'
,
`city_name` varchar(25) DEFAULT NULL COMMENT
'城市名稱'
,
`description` varchar(25) DEFAULT NULL COMMENT
'描述'
,
PRIMARY KEY (`
id
`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

c.插入數據java

|
INSERT city VALUES (1 ,1,
'溫嶺市'
,
'BYSocket 的家在溫嶺。'
);

org.spring.springboot.controller - Controller 層org.spring.springboot.dao - 數據操做層 DAOorg.spring.springboot.domain - 實體類org.spring.springboot.service - 業務邏輯層Application - 應用啓動類resources/application.properties - 應用配置文件,應用啓動會自動讀取配置resources/web - *.ftl文件,是 FreeMarker 文件配置路徑。在 application.properties 配置resources/mapper - DAO Maper XML 文件
