　　步骤一：在pom.xml文件中添加mysql和jpa的相关jar包依赖，具体添加位置在dependencies中，具体添加的内容如下所示。



org.springframework.boot
spring-boot-starter-web


org.springframework.boot
spring-boot-starter-data-jpa


mysql
mysql-connector-java


org.apache.poi
poi

步骤二：在application.properties配置文件中加入数据库的相关配置，配置信息如下所示。

spring.datasource.url = jdbc:mysql://localhost:3306/webtest
spring.datasource.username = root
spring.datasource.password = 220316
spring.datasource.driverclassname = com.mysql.jdbc.driver
# specify the dbms
spring.jpa.database = mysql
# show or not log for each sql query
spring.jpa.show-sql = true
# hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update
# naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.improvednamingstrategy
# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dial
