Springboot配置MySQL数据库

一、创建springboot项目，并添加如下依赖

<dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><scope>runtime</scope>
</dependency>

二、在application.properties中配置连接数据库信息

spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/数据库名称
spring.datasource.username=root
spring.datasource.password=密码

三、在启动类中创建代码，并运行测试：

@SpringBootApplication
public class DemoApplication {public static void main(String[] args) {ConfigurableApplicationContext context =SpringApplication.run(DemoApplication.class, args);JdbcTemplate jdbcTemplate = context.getBean(JdbcTemplate.class);List<Map<String, Object>> result =jdbcTemplate.queryForList("SELECT * FROM student");System.out.println(result);}
}

运行结果：

数据库数据：
