Failed to obtain JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory

引用\[1\]中提到，当访问自己的localhost时，出现了白页，并且控制台打印了"Failed to obtain JDBC Connection; nested exception is com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure"的错误信息。根据\[2\]中的引用，这个错误可能是由于数据库配置中的时区问题引起的。具体来说，错误信息中提到了"server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone"，这意味着数据库服务器的时区值无法识别或者表示了多个时区。为了解决这个问题，你需要配置数据库服务器或者JDBC驱动程序的"serverTimezone"属性，以使用更具体的时区值来支持时区功能。请检查你的数据库配置，确保"serverTimezone"属性设置正确。
