Hello friends,
Here i have given explaination about how to take backup of mysql database from java swings below example i have created with the help of NetBeans 6.1, we will describe this step bye step.
often you required to take backup of mysql databases from your swing application. You can use mysqldump to take Mysql backup here i have try to simplify it.
if you are using Net Beans IDE then this will be very easy.
Step 1. - create a jframe in swing as shown as following figure
Step2: write below code under event of choose button
choose menu is to select the folder where you wish to take your backup sql file.
I have achieved it by using JFileChooser component of swing.
txtbackuppath.setText(getBackUpPath());
//getBackUpPath() function is as shown below.
public static String getBackUpPath() {
String backUpPath = "";
JFileChooser fc = null;
if (fc == null) {
fc = new JFileChooser();
fc.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
fc.setAcceptAllFileFilterUsed(false);
}
int returnVal = fc.showDialog(null, "Open");
if (returnVal == JFileChooser.APPROVE_OPTION) {
File file = fc.getSelectedFile();
backUpPath = file.getAbsolutePath();
}
return backUpPath;
}
Hello friends uptill now we have seen that how we got the path where we can store the backup file of mysql database.
//above function is used to get the back up path dynamically by using jFileChooser component.
Now to connect with MySql we have required parameters such as Username, Password and database
name whose backup have to be taken it all shown in above figure.
Now we will see directly the code which is required for backup purpose.
this code is written under the backup button which is shown in above figure.
Step3: write below code under event of backup buttonname whose backup have to be taken it all shown in above figure.
Now we will see directly the code which is required for backup purpose.
this code is written under the backup button which is shown in above figure.
String backuppath=txtbackuppath.getText();
String Database =txtdatabasename.getText();
String Password =txtpassword.getText();
String user=txtuser.getText();
Backup b = new Backup();
try
{
byte[] data = b.getData("localhost", "3306", user, Password, Database).getBytes();
File filedst = new File(backuppath+"\\"+Database+".zip");
FileOutputStream dest = new FileOutputStream(filedst);
ZipOutputStream zip = new ZipOutputStream(
new BufferedOutputStream(dest));
zip.setMethod(ZipOutputStream.DEFLATED);
zip.setLevel(Deflater.BEST_COMPRESSION);
zip.putNextEntry(new ZipEntry("data.sql"));
zip.write(data);
zip.close();
dest.close();
JOptionPane.showMessageDialog(null, "Back Up Successfully."+"\n"+"For Database: "+Database+"\n "+"On Dated: ","Database BackUp Wizard",JOptionPane.INFORMATION_MESSAGE);
}catch (Exception ex){
JOptionPane.showMessageDialog(null, "Back Up Failed."+"\n"+"For Database: "+Database+"\n "+"On Dated: ","Database BackUp Wizard",JOptionPane.INFORMATION_MESSAGE);
ex.printStackTrace();
}
Hello friend this is what the code which takes the database backup in zipped format. it requires one more class file whose code i have given below
//It will require a "BackUp.java" file.
