MySQL provides connectivity for client applications developed in the Java programming language with MySQL Connector/J, a driver that implements the Java Database Connectivity (JDBC) API and also MySQL X DevAPI.
MySQL Connector/J 8.2 is a JDBC Type 4 driver that is compatible with 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.
For more information, please visit the official MySQL Connector/J documentation.
Please refer to the README and LICENSE files, available in this repository, and the Legal Notices in the MySQL Connector/J documentation for further details.
Getting the Latest Release
MySQL Connector/J is free for usage under the terms of the specified licensing and it runs on any operating system that is able to run a Java Virtual Machine.
Download and Install
MySQL Connector/J can be installed from pre-compiled packages that can be downloaded from the MySQL Connector/J download page. Installing MySQL Connector/J only requires obtaining the corresponding JAR file from the downloaded bundle or installer and including it in the application's CLASSPATH.
According to how you use MySQL Connector/J, you may also need to install the following third-party libraries on your system for it to work:
- Protocol Buffers (protobuf-java) is required for using X DevAPI
- Oracle Cloud Infrastructure SDK for Java (oci-java-sdk) is required to support OCI AIM authentication
- Simple Logging Facade API (slf4j-api) is required for using the logging capabilities provided by the default implementation of org.slf4j.Logger.Slf4JLogger by MySQL Connector/J
As a Maven Dependency
Alternatively, MySQL Connector/J can be obtained automatically via Maven's dependency management by adding the following configuration in the application's Project Object Model (POM) file:
<dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> <version>8.2.0</version> </dependency>
MySQL Connector/J's own Project Object Model (POM) file specifies a transitive dependency to Protocol Buffers (protobuf-java) since it is required for using X DevAPI. However, if you do not use the X DevAPI features, you may also want to add a dependency exclusion to avoid linking the unneeded sub-library. For example:
<dependency> <groupId>com.mysql</groupId> <artifactId>mysql-connector-j</artifactId> <version>8.2.0</version> <exclusions> <exclusion> <groupId>com.google.protobuf</groupId> <artifactId>protobuf-java</artifactId> </exclusion> </exclusions> </dependency>
