1. 驱动类 java.sql.Driver变为 com.mysql.cj.jdbc.Driver

URL 语法

protocol//[hosts][/database][?properties]

protocol
jdbc:mysql: is for ordinary and basic JDBC failover connections.

jdbc:mysql:loadbalance: is for load-balancing JDBC connections. See Section 9.3, “Configuring Load Balancing with Connector/J” for details.

jdbc:mysql:replication: is for JDBC replication connections. See Section 9.4, “Configuring Source/Replica Replication with Connector/J” for details.

mysqlx: is for X DevAPI connections.

jdbc:mysql+srv: is for ordinary and basic failover JDBC connections that make use of DNS SRV records.

jdbc:mysql+srv:loadbalance: is for load-balancing JDBC connections that make use of DNS SRV records.

jdbc:mysql+srv:replication: is for replication JDBC connections that make use of DNS SRV records.

mysqlx+srv: is for X DevAPI connections that make use of DNS SRV records.

多主机配置：

jdbc:mysql://myhost1:1111,myhost2:2222/db
jdbc:mysql://address=(host=myhost1)(port=1111)(key1=value1),address=(host=myhost2)(port=2222)(key2=value2)/db
jdbc:mysql://(host=myhost1,port=1111,key1=value1),(host=myhost2,port=2222,key2=value2)/db
jdbc:mysql://myhost1:1111,(host=myhost2,port=2222,key2=value2)/db
mysqlx://(address=host1:1111,priority=1,key1=value1),(address=host2:2222,priority=2,key2=value2)/db
