mysql的JDBC驅動程序
MySQL Connector/J is the official JDBC driver for MySQL. Online documentation for Connector/J can be found from here.
Connector/J 5.1 includes support for JDBC-4.0 functionality, including:
Ease-of-development features including auto-registration with the DriverManager via the service provider mechanism, standardized Connection validity checks and categorized SQLExceptions based on recoverability/retry-ability and class of the underlying error.
Unwrapping to interfaces that include vendor extensions
Support for XML processing via JAXP interfaces to DOM, SAX and StAX
Support for setting per-connection client information (which can be viewed in the comments section of a query via "SHOW PROCESSLIST" on a Mysql server, or can be extended to support custom persistence of the information via a public interface)
Support for JDBC-4.0 NCHAR, NVARCHAR and NCLOB types
