Spring Boot 集成 FreeMarker 详解案例(十五)
一、Springboot 那些事
二、运行 springboot-freemarker 工程
a.创建数据库 springbootdb:
|
1
|
CREATE DATABASE springbootdb; |
|

|
DROP TABLE IF EXISTS `city`;CREATE TABLE `city` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT '城市编号', `province_id` int(10) unsigned NOT NULL COMMENT '省份编号', `city_name` varchar(25) DEFAULT NULL COMMENT '城市名称', `description` varchar(25) DEFAULT NULL COMMENT '描述', PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8; |
c.插入数据
|
1
|
INSERT city VALUES (1 ,1,'温岭市','BYSocket 的家在温岭。'); |
org.spring.springboot.controller - Controller 层org.spring.springboot.dao - 数据操作层 DAOorg.spring.springboot.domain - 实体类org.spring.springboot.service - 业务逻辑层Application - 应用启动类resources/application.properties - 应用配置文件,应用启动会自动读取配置resources/web - *.ftl文件,是 FreeMarker 文件配置路径。在 application.properties 配置resources/mapper - DAO Maper XML 文件

localhost:8080/api/city |
