//比较低的版本 spring.datasource.driver-class-name=com.mysql.jdbc.Driver

//高版本 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver <dependency> <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-jdbc</artifactId>
		
    </dependency>

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