尝试将 MySQL 服务器连接到 Spring Boot App STS 时出现多个错误

Question

我正在尝试使用 Spring Tool Suite 在 Spring Boot 中连接到 MySQL 服务器。即使我的数据库正在运行并创建了架构，我也会收到以下错误：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 datasourceWARN 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.
