怎样加载mysql数据库驱动程序？1,首先写个方法package util;import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;public class DBUtil { static String jdbcURL = "jdbc:mysql://localhost:3306/book";
static String jdbcDriver = "com.mysql.jdbc.Driver";
static String userName = "root";
static String password = "root";
/**
* 获取数据库连接对象
* @return 数据库连接对象
* @throws ClassNotFoundException
* @throws SQLException
*/
public static Connection getConnection() throws ClassNotFoundException,
SQLException {
Class.forName(jdbcDriver);
return DriverManager.getConnection(jdbcURL, userName, password);
}
} 2 。项目名==右键==build path==add external archivers.... 选择你mysql驱动 添加进去就ok了

加载MYSQL JDBC驱动问题区别是你导mysql驱动怎么加载了三个不同mysql驱动怎么加载的jar包mysql驱动怎么加载，创建数据库连接驱动mysql驱动怎么加载，javaJDK并没有提供完整的实现，但是支持组建的实现，所有就有了好多不同机构对他做了具体的实现 ， 需要导入一个driver包，后缀为.jar 。你导不同的jar包，jar包定义的路径都不同 ， 他们之间没有实质的差别 。一般来讲我们都是用的第二个，据说是因为稳定 。
java链接mysql的时候怎么加载驱动是这样的，首先你会发现这句话会抛出一个异常ClassNotFoundException（无法找到驱动类）驱动是在程序第一次运行的时候进行加载，如果你是发布到服务器上并且加载后运行了一遍 ， 那么第二次注视了确实没有什么问题 。这是你的第一个问题 。第二个来说就是首先你需要定义好一个针对于数据库的连接，这个连接如果被你的程序调用那么就可以用来访问数据库，其中的字符串第一个就是你定义的连接名称（连接服务名称），第二个是你的数据库登陆名称 ， 第三个就是对应的密码 。
关于MySQL数据库加载驱动的一点小问题不需修改，参照如下：
Oracle数据库:
驱动程序包名：ojdbc14.jar
驱动类的名字：oracle.jdbc.driver.OracleDriver
JDBC URL：jdbc:oracle:thin:@dbip:port:databasename
说明：驱动程序包名有可能会变
JDBC URL中各个部分含义如下：
dbip –为数据库服务器的IP地址，如果是本地可写：localhost或127.0.0.1 。
port –为数据库的监听端口，需要看安装时的配置，缺省为1521 。
databasename –为数据库的SID，通常为全局数据库的名字 。
SQL Server数据库
驱动程序包名：msbase.jar mssqlserver.jar msutil.jar
驱动类的名字：com.microsoft.jdbc.sqlserver.SQLServerDriver
JDBC URL：jdbc:microsoft:sqlserver://dbip:port;DatabaseName=databasename
说明：驱动程序包名有可能会变
JDBC URL中各个部分含义如下：
dbip –为数据库服务器的IP地址，如果是本地可写：localhost或127.0.0.1 。
port –为数据库的监听端口，需要看安装时的配置，缺省为1433 。
databasename –数据库的名字 。
MySQL数据库
【mysql驱动怎么加载 mysql驱动加载失败】驱动程序包名：mysql-connector-Java-3.1.11-bin.jar
驱动类的名字：com.mysql.jdbc.Driver
JDBC URL：jdbc:mysql://dbip:port/databasename
说明：驱动程序包名有可能会变
JDBC URL其中各个部分含义如下：
dbip –为数据库服务器的IP地址，如果是本地可写：localhost或127.0.0.1 。
port –为数据库的监听端口，需要看安装时的配置，缺省为3306 。
databasename –数据库的名字 。
mysql驱动怎么加载的介绍就聊到这里吧，感谢你花时间阅读本站内容，更多关于mysql驱动加载失败、mysql驱动怎么加载的信息别忘了在本站进行查找喔 。
