3.1 Overview of MySQL Connector/J

MySQL provides connectivity for client applications developed in the Java programming language with MySQL Connector/J. Connector/J implements the Java Database Connectivity (JDBC) API, as well as a number of value-adding extensions of it. It also supports the new X DevAPI.

MySQL Connector/J is a JDBC Type 4 driver, implementing the JDBC 4.2 specification. The Type 4 designation means that the driver is a pure Java implementation of the MySQL protocol and does not rely on the MySQL client libraries. See Section 3.2, “Compatibility with MySQL and Java Versions” for compatibility information.

Connector/J 8.0 provides ease of development features including auto-registration with the Driver Manager, standardized validity checks, categorized SQLExceptions, support for large update counts, support for local and offset date-time variants from the java.time package, support for JDBC-4.x XML processing, support for per connection client information, and support for the NCHAR, NVARCHAR and NCLOB data types. See Section 3.2, “Compatibility with MySQL and Java Versions” for compatibility information.

For large-scale programs that use common design patterns of data access, consider using one of the popular persistence frameworks such as Hibernate, Spring's JDBC templates or MyBatis SQL Maps to reduce the amount of JDBC code for you to debug, tune, secure, and maintain.
