微信点餐系统html,SpringBoot实战——微信点餐系统(示例代码)
1、初始化项目
引入模块
org.springframework.boot
spring-boot-starter-data-jpa
org.springframework.boot
spring-boot-starter-web
mysql
mysql-connector-java
runtime
org.projectlombok
lombok
true
org.springframework.boot
spring-boot-starter-test
test
2、application.properties
(1)改成application.yml，yml可读性较强 编辑较为简单
(2)添加数据库配置
spring:
datasource:
url: http://localhost:3036/sell?useUnicode=true&&characterEncoding=utf-8
driver-class-name: com.mysql.jdbc.Driver
username: root
password: root
jpa:
show-sql: truefreemarker:
allow-request-override: falsecache:falsecheck-template-location: truecharset: utf-8content-type: text/html
suffix: .ftl
template-loader-path: classpath:/templates/
3、创建数据库
