在spring-boot jpa hibernate中，连接到数据库在大于4小时小于24小时后断开。

我有一个使用spring-boot、jpa-hibernate和mysql的应用程序。我遇到了以下错误日志：\n

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 56,006,037 milliseconds ago.  The last packet sent successfully to the server was 56,006,037 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

\n这是我的application.properties文件：\n

# DataSource settings: set here configurations for the database connection
spring.datasource.url = jdbc:mysql://localhost:3306/test
spring.datasource.username = test
spring.datasource.password = test
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 settings are prefixed with spring.jpa.hibernate.*
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy

\n要解决此问题，我可以使用以下配置：\nspring.datasource.testOnBorrow=true\nspring.datasource.validationQuery=SELECT 1\n\n但我检查了一下，这不是推荐的做法。所以有人能给我建议应该怎么解决这个错误吗？
