Question

我正在尝试使用Spring Tool Suite在Spring Boot中建立与MySQL服务器的连接。即使我的数据库正在运行并创建了架构，我仍然遇到以下错误：

WARN 44756 --- [  restartedMain] com.zaxxer.hikari.util.DriverDataSource  : Registered driver with driverClassName=com.mysql.jdbc.Driver was not found, trying direct instantiation.

ERROR 44756 --- [  restartedMain] com.zaxxer.hikari.pool.HikariPool       : HikariPool-1 - Exception during pool initialization.

WARN 44756 --- [  restartedMain] o.s.b.a.orm.jpa.DatabaseLookup           : Unable to determine jdbc url from datasource

WARN 44756 --- [  restartedMain] o.h.e.j.e.i.JdbcEnvironmentInitiator     : HHH000342: Could not obtain connection to query metadata : The server time zone value 'PDT' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

WARN 44756 --- [  restartedMain] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

我正在使用以下application.properties：

spring.datasource.url=jdbc:mysql://localhost:3306/book-schema
spring.datasource.username=root spring.datasource.password=root1234
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update

我不确定是什么引起了这个问题。
