It is compatible with all MySQL versions starting from MySQL 5.6 and supports both legacy and modern SQL modes.
It is easy to install, configure, and use. You just need to download a single jar file and add it to your classpath or project dependencies.
It is highly performant, scalable, and reliable. It uses efficient network communication, caching mechanisms, connection pooling, statement pooling, and result set streaming to optimize resource usage and throughput.
It is flexible and customizable. You can choose from various connection options, load balancing strategies, exception handling policies, logging frameworks, interceptor classes, and more to suit your application needs.
It is well documented and supported. You can find comprehensive documentation, release notes, examples, tutorials, forums, blogs, bug reports, and support services on the official MySQL website.
What are the Common Issues with MySQL Connector Java and How to Solve Them?
Despite its advantages, MySQL Connector Java may also encounter some issues or limitations due to compatibility problems, configuration errors, network failures, server issues, or application bugs. Some of the common issues with MySQL Connector Java are:
SQLException: Server configuration denies access to data source. This means that the security manager on the MySQL server does not allow TCP/IP connections from your client. To solve this issue, you need to grant the necessary privileges to your MySQL user account using a GRANT statement.
SQLException: No suitable driver. This means that the JDBC driver class cannot be found or loaded by your Java application. To solve this issue, you need to make sure that the mysql connector java jar file is in your classpath or project dependencies and that you specify the correct driver class name (com.mysql.cj.jdbc.Driver) when loading the driver.
SQLException: Cannot connect to MySQL server on host:port. This means that there is a network problem or a firewall blocking the connection between your client and server. To solve this issue, you need to check your network connectivity, firewall settings, server status, connection URL syntax, and connection properties.
SQLException: Communications link failure Last packet sent to the server was X ms ago. This means that the connection was lost or timed out due to a network failure, a server crash, or a long-running query. To solve this issue, you need to check your network reliability, server availability, query performance, and connection timeout settings.
SQLException: Data truncation. This means that the data you are trying to insert or update is too large or too small for the column type or size. To solve this issue, you need to check your data values, column definitions, and SQL modes.
SQLException: Unsupported character encoding. This means that the character set or collation of your data does not match the character set or collation of your database, table, column, or connection. To solve this issue, you need to check your character set and collation settings and use the appropriate conversion functions.

Load the driver class and establish a connection to MySQL database. You can use the Class.forName method to load the driver class (com.mysql.cj.jdbc.Driver) and the DriverManager.getConnection method to obtain a Connection object using a connection URL that specifies the database name, host name, port number, user name, password, and other connection properties . For example:Class.forName("com.mysql.cj.jdbc.Driver"); Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test?user=root&password=root&useSSL=false");
Execute queries and handle results using JDBC API. You can use various classes and interfaces fro
