MySQL Connector/J

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 8.0 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.

The driver also contains an implementation of MySQL X DevAPI, an application programming interface for working with MySQL as a Document Store through CRUD-based, NoSQL operations.

For more information, please visit the official MySQL Connector/J documentation.

Licensing

Please refer to the README and LICENSE files, available in this repository, and the Legal Notices in the 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 Connector/J download page. Installing 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 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 Connector/J

As a Maven Dependency

Alternatively, 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>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>8.0.29</version>
</dependency>

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>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>8.0.29</version>
  <exclusions>
    <exclusion>
      <groupId>com.google.protobuf</groupId>
      <artifactId>protobuf-java</artifactId>
    </exclusion>
  </exclusions> 
</dependency>

Build From Source

This driver can also be complied and installed from the source available in this repository. Please refer to the Connector/J documentation for detailed instructions on how to do it.
