com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException异常解决方法

在使用MySQL驱动进行JDBC时候出现了以下异常

Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server.at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)at java.lang.reflect.Constructor.newInstance(Constructor.java:423)at com.mysql.jdbc.Util.handleNewInstance(Util.java:408)at com.mysql.jdbc.Util.getInstance(Util.java:383)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:1023)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:997)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:983)at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:928)at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2576)at com.mysql.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:2309)at com.mysql.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:834)at com.mysql.jdbc.JDBC4Connection.<init>(JDBC4Connection.java:46)at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)at java.lang.reflect.Constructor.newInstance(Constructor.java:423)at com.mysql.jdbc.Util.handleNewInstance(Util.java:408)at com.mysql.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:419)at com.mysql.jdbc.NonRegisteringDriver.connect(Loading class `com.mysql.jdbc.Driver'.

看异常好像是无事务连接异常，无法创建连接。我在另一个电脑上是没有这个异常的，也就在我这台电脑上才遇到了。猜想可能是MySQL版本和驱动包不兼容的问题，所以将MySQL驱动改为了最新的8.0版本的MySQL驱动，但是又出现了下面的错误

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
Exception in thread "main" java.sql.SQLException: The server time zone value '?й???????' 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.at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:129)at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:97)at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:89)at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:63)at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:73)at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:76)at com.mysql.cj.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:835)at com.mysql.cj.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:455)at com.mysql.cj.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:240)at com.mysql.cj.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:199)at java.sql.DriverManager.getConnection(DriverManager.java:664)at java.sql.DriverManager.getConnection(DriverManager.java:247)

显示是说我用的那个驱动类已经过时了，新的驱动类是“com.mysql.cj.jdbc.Driver”，而不是“com.mysql.jdbc.Driver”了，并且还说我没有配置时区，查了一下，原来从JDBC6.0开始驱动类使用了新的，并且url中必须要设置时区，否侧会报错。那按照规定改就行了。
所以，总结起来就三步:

第一步：使用最新的MySQL驱动jar包。
第二步：把驱动的类名改为:
static String driver="com.mysql.cj.jdbc.Driver";
第三步：在访问mysql的url后加入时区设置：
static String url="jdbc:mysql://localhost:3306/test?characterEncoding=utf-8&serverTimezone=UTC";(UTC表示标准时区)

这样，就可以开开心心的访问MySQL数据库了。
