The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone
在闲暇之余使用Hibernate做个练习顺便回顾一下曾经的使用经历，没成想，在开发过程中遇到了大大小小的问题，但是其中一个问题对于我来说比较郁闷，就是标题所描述的这个问题，此问题找了半天，也没找到啥原因，上个刚搭建时的配置文件：
com.mysql.cj.jdbc.Driver
jdbc:mysql://localhost:3306/hibernatetest?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC
root
123 这个是刚开始配置的文件，但是呢，这个配置在编辑器里边是报错的，如图：
报错的地方描述如下：
错误信息使用有道翻译过来，是：
看着翻译的内容得出xml中不支持这种方式的连接符， 然后将其中的&符号替换成了分号“；”，然后错误就消失了
改为分号时，错误消失了，这时就可以尝试继续测试程序了，测试程序如下：
package com.hibernateTest;
import java.util.Date;
import com.hibernate.domain.Customer;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;
public class HibernateTest {
@Test
public void test() {
Customer c = new Customer("张三", false, new Date());
Configuration cfg = new Configuration();
cfg.configure();
SessionFactory sessionFactory = cfg.buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
session.save(c);
transaction.commit();
session.close();
sessionFactory.close();
}
}但是，天公不做美，控制台有抛出了异常信息，内容如下：

最后上了趟厕所，回来以后，想到xml文件配置url后边加参数，是不是不支持分号的这种写法，最后找度娘问了一下还真是，最后果断改成xml支持的方式，改为：
jdbc:mysql://localhost:3306/hibernatetest?userUnicode=true;characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true 再次测试程序：
程序测试成功；
