connecting to MySQL using JDBC in eclipse
So I want to create a JDBC connection to MySQL server that is installed on my pc, here are the steps, I installed MySQL with the username and password "root", downloaded mysql-connector-java and from theere I coped the JAR "mysql-connector-java-5.1.12-bin" to "C:\Sun\SDK\jdk\jre\lib\ext", I then added it as an external JAR in my project in eclipse, now in my class I have this code:
public void initialiseDatabase()
{
try {
// Load the Driver class.
Class.forName("com.mysql.jdbc.Driver");
//Create the connection using the static getConnection method
databaseConnection = DriverManager.getConnection (databaseUrl+databaseName,
dbUserName, dbPassword);
sqlStatement = databaseConnection.createStatement();
}
catch (SQLException e) {e.printStackTrace();}
catch (Exception e) {e.printStackTrace();}
}
(this is going to开发者_如何学运维 be psuedocode cause I am reading from a properties file and don't want the one helping me reading through long lines of code from main to figure out all the variables), where databaseUrl = "127.0.0.1" dbUserName = "root" dbPassword = "root" databaseName = "MySQL" //this one I am not sure of, do I need to create it or is it set inherenrly?
now the MySQL server is up and running, but when I call the method initialiseDatabase the following exception is thrown: "java.sql.SQLException: No suitable driver found for rootroot at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at Proxy$JDBCConnection.initialiseDatabase(Proxy.java:721)"
when line 721 is: sqlStatement = databaseConnection.createStatement();
Where have I gone wrong?
thanks
Your database url should look like this:
jdbc:mysql://host:port/database
Example, if you use localhost, the default port and a database named cachedb, your url would be:
jdbc:mysql://localhost/cachedb
