idea-Springboot添加依赖以及连接mysql--002

1.添加mysql和mybatis的依赖

以及修改版本匹配，本地安装的mysql 是5.8的此处mysql依赖添加的是6.0.6
此处可以去maven仓库进行搜索添加。仓库地址：

		<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.1.4</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>6.0.6</version>
        </dependency>

2.创建或者修改成yml文件

在里面创建连接mysql

server:
  port: 8080
  servlet:
    context-path: /showtime
spring:
 datasource:
    username: root
    password: root
    url: jdbc:mysql://localhost:3306/showtime?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.cj.jdbc.Driver
