MySQL :: MySQL Connector/J 8.0 Developer Guide :: 4.3.1.3 Changes in the Connector/J API https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-api-changes.html
4.3.1.3 Changes in the Connector/J API
This section describes the changes to the Connector/J API going from version 5.1 to 8.0. You might need to adjust your API calls accordingly:
-
The name of the class that implements
java.sql.Driver
in MySQL Connector/J has changed fromcom.mysql.jdbc.Driver
tocom.mysql.cj.jdbc.Driver
. The old class name has been deprecated. -
The names of these commonly-used interfaces have also been changed:
-
ExceptionInterceptor: from
com.mysql.jdbc.ExceptionInterceptor
tocom.mysql.cj.exceptions.ExceptionInterceptor
-
StatementInterceptor: from
com.mysql.jdbc.StatementInterceptorV2
tocom.mysql.cj.interceptors.QueryInterceptor
-
ConnectionLifecycleInterceptor: from
com.mysql.jdbc.ConnectionLifecycleInterceptor
tocom.mysql.cj.jdbc.interceptors.ConnectionLifecycleInterceptor
-
AuthenticationPlugin: from
com.mysql.jdbc.AuthenticationPlugin
tocom.mysql.cj.protocol.AuthenticationPlugin
-
BalanceStrategy: from
com.mysql.jdbc.BalanceStrategy
tocom.mysql.cj.jdbc.ha.BalanceStrategy
. -
-
信息: Loading XML bean definitions from class path resource [Beans.xml]
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.

com.mysql.jdbc.Driver 与 org.gjt.mm.mysql.Driver的区别
com.mysql.jdbc.Driver的前身是org.gjt.mm.mysql.Driver,现在主要用com.mysql.jdbc.Driver,但为了保持兼容性保留了org.gjt.mm.mysql.Driver这个路径的引用。
mysql-connector-java-5.1.40.jar包结构:
com.mysql.jdbc.Driver.java 代码:
package com.mysql.jdbc;
import java.sql.DriverManager;
import java.sql.SQLException;
public class Driver extends NonRegisteringDriver implements java.sql.Driver {
public Driver() throws SQLException {
}
static {
try {
DriverManager.registerDriver(new Driver());
} catch (SQLException var1) {
throw new RuntimeException("Can''t register driver!");
}
}
}
org.gjt.mm.mysql.Driver.java 代码:
package org.gjt.mm.mysql;
import java.sql.SQLException;
public class Driver extends com.mysql.jdbc.Driver {
public Driver() throws SQLException {
}
}
可以总结出MySQL公司为了保持兼容性让org.gjt.mm.mysql.Driver对com.mysql.jdbc.Driver进行了简单的继承。
com.mysql.jdbc.Driver 和 com.mysql.cj.jdbc.Driver 的区别
调试代码时,发现错误:
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.
在网上巴拉巴拉发现,原来:
com.mysql.jdbc.Driver
是 mysql-connector-java 5 中的;com.mysql.cj.jdbc.Driver
是 mysql-connector-java 6 中的。
1、JDBC 连接 Mysql5 com.mysql.jdbc.Driver:
spring:
# 数据库连接
datasource:
url: jdbc:mysql://192.168.1.1:3306/demo?useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
2、JDBC 连接 Mysql6 com.mysql.jdbc.Driver,需要指定时区serverTimezone:
spring:
# 数据库连接
datasource:
url: jdbc:mysql://192.168.1.1:3306/demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf8&useSSL=false
# 在设定时区的时候,如果设定serverTimezone=UTC,会比中国时间早8个小时,如果在中国,可以选择Asia/Shanghai或者Asia/Hongkong,例如:
# ?serverTimezone=Shanghai&useUnicode=true&characterEncoding=utf8&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.cj.jdbc.Driver
今天关于com.mysql.jdbc.ServerPreparedStatement.BindValue的实例源码的分享就到这里,希望大家有所收获,若想了解更多关于centos7 设置 mysql 自启动的配置文件中 [Service] User=mysql Group=mysql,user 和 group 这边的 mysql 是指的什么?centos 的登录用户名?、com.mysql.jdbc.Driver to com.mysql.cj.jdbc.Driver、com.mysql.jdbc.Driver 与 org.gjt.mm.mysql.Driver的区别、com.mysql.jdbc.Driver 和 com.mysql.cj.jdbc.Driver 的区别等相关知识,可以在本站进行查询。
