mysql连接数据库

在程序中引入mysql的驱动包mysql-connector-java-5.0.5-bin.jar

完整的程序如下：
package mysql;

import java.sql.*;

public class MysqlTest {

/**
* @param args
*/
public static void main(String[] args) {
// TODO 自动生成方法存根
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
Class.forName("com.mysql.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost/test?"
+ "user=root&password=520wjb");
stmt = conn.createStatement();
String str = "Select * from users;";
rs = stmt.executeQuery(str);
while (rs.next()) {
System.out.println(rs.getInt(1));
System.out.println(rs.getString(2));

}

} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException ex) {
ex.printStackTrace();
System.out.println("SQLException: " + ex.getMessage());
System.out.println("SQLState: " + ex.getSQLState());
System.out.println("VendorError: " + ex.getErrorCode());
} finally {
try {
if (rs != null) {
rs.close();
rs = null;
}

if (stmt != null) {
stmt.close();
stmt = null;
}

if (conn != null) {
conn.close();
conn = null;
}
} catch (SQLException e) {
e.printStackTrace();
}
}

}

}
