springboot框架快速搭建

1. 新建Maven项目 springboot

2. pom.xml

3. /springboot/src/main/resources 目录下文件

4. application.properties

server.port=8080

spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp

5. log4j.properties

7. 创建数据库

DROP DATABASE IF EXISTS springboot;
CREATE DATABASE springboot;
USE springboot;
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` varchar(32) NOT NULL,
  `username` varchar(32) NOT NULL,
