![]() ![]() That means the program has successfully connected to the MySQL database server.Package de. import import import import import import import java.util. If you don’t know how to download and install MySQL command-line client and MySQL Workbench to your system, then you can follow the links given below for the proper installation process step by step. MySQLConnectExampleĪnd here is the result when running the example program: MySQL workbench is nothing but a GUI version of the MySQL console where we can visually design, model, and generate databases. Java -cp mysql-connector-java-5.1.21-bin.jar. Javac MySQLConnectExample.javaSuppose the Connect/J library is placed in the same directory as the MySQLConnectExample.java file. } NOTES: You should close the database connection in the finally clause like this: finally Type the following command to compile the example program: String url3 = "jdbc:mysql://localhost:3306/test3" Ĭonn3 = DriverManager.getConnection(url3, info) String url2 = "jdbc:mysql://localhost:3306/test2?user=root&password=secret" Ĭonn2 = DriverManager.getConnection(url2) String url1 = "jdbc:mysql://localhost:3306/test1" Ĭonn1 = DriverManager.getConnection(url1, user, password) creates three different Connection objects Java code example connect to MySQL databaseThe following example program makes three connections to three MySQL database in three different ways: import If a connection was made successfully with the database, the getConnection() method returns an instance of Connection class which will be used to make queries and perform other database operations. For example, to send a username and password, write: ?user=root&password=secret propertyName1=propertyValue1: a key=value pair for an additional property which will be sent to the server.database: name of the database on the server.port: port number of the server, default is 3306.host: host name or IP address of the MySQL server.static Connection getConnection(String url, String user, String password)Īll three versions have a parameter called urlwhich is the database URL string in the following format: jdbc:mysql:// /.static Connection getConnection(String url, Properties info).static Connection getConnection(String url).Just using the method getConnection()of the class DriverManager which is available in the package are three different signatures of the method getConnection()which we can use: JDBC API uses JDBC drivers to connect with the database. Java jdk1.6.0jre MySQL ver 14.12 Distrib 5.0. ![]() Understand the getConnection() method of DriverManager classIt’s quite easy to make a connection to a database server in general, as well as to a MySQL server in particular. As long as you put the MySQL JDBC driver JAR file file into your program’s classpath, the driver manager can find and load the driver. Before Java 6, we have to load the driver explicitly by this statement:Ĭlass.forName(".jdbc.Driver") However that statement is no longer needed, thanks to new update in JDBC 4.0 comes from Java 6. No need to load MySQL driver class explicitlyThe Connector/J version 8.0 library comes with a JDBC driver class: .jdbc.Driver. You can use newer version of JDBC driver for MySQL.If your Java project based on Maven, you just need to declare the following dependency in the pom.xml file: Copy this file into your project and make it available in your program’s classpath. But only one file we need is the JAR file mysql-connector-java-VERSION.jar. The distribution includes a binary JAR file, source code, documentation and license files. Extract the ZIP file to a desired location on your computer. Click the Download button next to Platform Independent (Architecture Independent), ZIP Archive to download a zip archive. The latest version 8.0 supports JDBC 4.2 and JDK 8 or higher. The MySQL JDBC Driver enables users to connect with live MySQL data. MySQL Connector/J comes into 2 major versions: 5.1 and 8.0. Easily connect live MySQL data with Java-based BI, ETL, Reporting, & Custom Apps. Browse this URL: download the latest version of the JDBC driver for MySQL called Connector/J. ![]() Download JDBC driver for MySQLFirst, in order to have Java program working with MySQL, we need a JDBC driver for MySQL. Java code example connects to MySQL database 1. Understand the getConnection() method of DriverManager classĤ. No need to load MySQL driver class explicitlyģ. If you have never written Java code to connect MySQL before, it’s worth reading this tutorial from the beginning.Table of content:Ģ. If you just want to see the code example, click on Code example: a simple program connects to MySQL. This article explains how to write Java code to connect to a MySQL database server, step by step. ![]()
