Springboot 配置 application.yml 连接MySQL数据库

1.在pom.xml的<dependencies></dependencies>标签中中加入以下依赖

         <dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-web</artifactId>
         </dependency>

         <dependency>
             <groupId>org.mybatis.spring.boot</groupId>
             <artifactId>mybatis-spring-boot-starter</artifactId>
             <version>2.0.1</version>
         </dependency>

         <dependency>
             <groupId>mysql</groupId>
             <artifactId>mysql-connector-java</artifactId>
             <scope>runtime</scope>
         </dependency>

         <dependency>
             <groupId>com.alibaba</groupId>
             <artifactId>druid</artifactId>
             <version>1.1.10</version>
         </dependency>

2.把resource包下的application.properties复制一份再粘贴名字改成application.yml，加入以下内容

 server:
   port: 8080
   servlet:
     context-path: /
 spring:
   datasource:
     username: root
     password: 123456
     url: jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
     type: com.alibaba.druid.pool.DruidDataSource
     driver-class-name: com.mysql.cj.jdbc.Driver

我的数据库密码是123456，数据库名是mybatis
