1、初始化项目
引入模块
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
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: true
freemarker:
allow-request-override: false
cache: false
check-template-location: true
charset: utf-8
content-type: text/html
suffix: .ftl
template-loader-path: classpath:/templates/
3、创建数据库

`detail_id` varchar(32) NOT NULL,

) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='类别表';
CREATE TABLE `product_info` (
