MySQL数据库的备份，我能够使用mysqldump.exe与下面的Java代码的帮助下创建一个备份我目前的MySQL数据库作为.SQL文件。如何恢复使用Java
Process runProcess = Runtime.getRuntime().exec("C:\\SCM Files\\SQL Backup\\mysqldump.exe -uroot -p123 rr -r\"C:\\SCM Files\\SQL Backup\\RR.sql");
现在我想恢复此相同的.SQL备份文件 MySQL数据库使用Java类似于上面的一个按钮点击的事件代码。
感谢很多:)
所以现在我尝试这样做; Process runProcess = Runtime.getRuntime().exec("C:\\SCM Files\\SQL Backup\\mysqldump.exe -uroot -p123 rr < C:\\SCM Files\\SQL Backup\\RR.sql"); 仍然没有奏效：/
Runtime.getRuntime().exec("mysql -u username -ppassword database_name FILE.sql")
本声明将重新生成数据库从文件
更具体地说-e“\。file.sql”或-e“source file.sql”参见[batch-mode]（http://dev.mysql.com） /doc/refman/5.5/en/batch-mode.html）但使用字符串数组 – KCD 2012-04-20 04:12:40
你应该尝试DbUnit备份和database.Here的恢复是为演示代码：
try {
Class.forName(DBDRIVER);
Connection jdbcConnection = DriverManager.getConnection(DBURL, DBUSERNAME, DBPASSWORD);
IDatabaseConnection connection = new DatabaseConnection(jdbcConnection);
connection.getConfig().setProperty(DatabaseConfig.PROPERTY_DATATYPE_FACTORY,
new MySqlDataTypeFactory());
//////// Database backup
ITableFilter filter = new DatabaseSequenceFilter(connection);
IDataSet dataset = new FilteredDataSet(filter, connection.createDataSet());
ExcludeTableFilter excludeFilter = new ExcludeTableFilter();
excludeFilter.excludeTable("DATABASECHANGELOG*");
IDataSet excludedataset = new FilteredDataSet(excludeFilter, dataset);
FlatXmlDataSet.write(excludedataset, new FileOutputStream(backupfilename));
System.out.println("\n Complete backup successful.");
//////// Database backup
//////// Database restore
IDataSetProducer producer = new FlatXmlProducer(new InputSource(restoreFileName));
IDataSet dataSet = new StreamingDataSet(producer);
TransactionOperation operation = new TransactionOperation(DatabaseOperation.INSERT);
operation.execute(connection, dataSet);
//////// Database restore
} catch (DatabaseUnitException e) {
e.printStackTrace();
flag = false;
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
你必须在那里你可以用java波动设计形式。这是一些可以做到的代码。
import javax.swing.JFrame;
public final class RestoreMySQLDatabase extends JFrame {
private static final long serialVersionUID = 1L;
public static void main(String[] args) {
RestoreMySQLDatabase restoreMySQL = new RestoreMySQLDatabase();
restoreMySQL.setTitle("Restore mysql database");
javax.swing.JButton butRestore = new javax.swing.JButton("Restore");
butRestore.addActionListener(new java.awt.event.ActionListener(){
public void actionPerformed(java.awt.event.ActionEvent event){
try{
Runtime.getRuntime().exec("C:\\SCM Files\\SQL Backup\\mysqldump.exe -uroot -p123 rr -r\"C:\\SCM Files\\SQL Backup\\RR.sql");
javax.swing.JOptionPane.showMessageDialog((javax.swing.JButton)event.getSource(), "Successfully restored");
}catch(java.lang.Exception e){
javax.swing.JOptionPane.showMessageDialog((javax.swing.JButton)event.getSource(), "Not able to restore");
}
}
});
}
}
使用相同的转储导入这样。
Process runProcess = Runtime.getRuntime().exec("C:\\SCM Files\\SQL Backup\\mysqldump.exe -uroot -p123 rr database_name < "C:\\SCM Files\\SQL Backup\\RR.sql");
这不起作用：/ 'Process runProcess = Runtime.getRuntime（）.exec（“C：\\ SCM Files \ \ SQL备份\\ mysqldump.exe -uroot -p123 rr
public static boolean restoreDB(String dbName, String dbUserName, String dbPassword, String source) {
String[] executeCmd = new String[]{"mysql", "--user=" + dbUserName, "--password=" + dbPassword, dbName,"-e", " source "+source};
Process runtimeProcess;
try {
runtimeProcess = Runtime.getRuntime().exec(executeCmd);
int processComplete = runtimeProcess.waitFor();
if (processComplete == 0) {
System.out.println("Backup restored successfully");
return true;
}
} else {
System.out.println("Could not restore the backup");
}
} catch (Exception ex) {
ex.printStackTrace();
}
return false;
}
源例如： “E：\\我的备份\\测试\\ file.sql”

对于恢复使用在提供的表单m.Torkashvand（字符串数组）的executeCmd。关于如何使用从JSP代码这些命令的工作的例子可以发现here
public static void mysqlExport(String host, String port, String user, String password, String dbname, String table, String folder, String query) {
System.out.println("------ Exporting "+dbname+"."+table+" at "+folder+"---------------------------");
try {
String command = "mysqldump --host=" + host + " --port=" + port + " --user=" + user + " --password=" + password + " " + dbname + " " + table + " --where=\"" + query + "\" > " + folder + table + ".sql";
System.out.println(command);
int returnValue = executeCommand(Arrays.asList("mysqldump", "--host="+host, "--port="+port, "--user="+user, "--password="+password, dbname, table, "--where="+query), folder + table + ".sql");
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
public static void mysqlImport(String host, String port, String user, String password, String dbname, String table, String folder) {
System.out.println("------ Importing "+dbname+"."+table+" at "+folder+"---------------------------");
try {
String command = "mysql --host=" + host + " --port=" + port + " --user=" + user + " --password=" + password + " " + dbname + " " + table + " < " + folder + table + ".sql";
System.out.println(command);
int returnValue = executeCommand(new String[]{"mysql", "--host="+host, "--port="+port, "--user=" + user, "--password=" + password, dbname, "-e", "source " + folder + table + ".sql"});
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
public static int executeCommand(String[] commands) throws IOException
{
System.out.println(commands.toString());
Process process = Runtime.getRuntime().exec(commands);
return dumpProcess(process);
}
public static int executeCommand(List<String> commands, String folder) throws IOException
{
ProcessBuilder builder = new ProcessBuilder(commands);
System.out.println(builder.command());
builder.redirectOutput(new File(folder));
Process process = builder.start();
return dumpProcess(process);
}
public static int dumpProcess(Process process) throws IOException
{
int returnValue = -1;
try {
String s = null;
process.waitFor();
returnValue = process.exitValue();
if (returnValue == 0) {
System.out.println("Command successful !!");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream()));
System.out.println("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
} else {
System.out.println("Command failed. Exist Status code = "+returnValue);
BufferedReader stdError = new BufferedReader(new InputStreamReader(process.getErrorStream()));
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
}
} catch (InterruptedException e) {
e.printStackTrace();
}
return returnValue;
}
我尝试此代码，可以作为完美！
String[] restoreCmd = new String[]{"mysql ", "--user=" + DB.DB_USERNAME, "--password=" + DB.DB_PASSWORD, "-e", "source " + pathToFile};
try {
Process runtimeProcess = Runtime.getRuntime().exec(restoreCmd);
int processComplete = runtimeProcess.waitFor();
if (processComplete == 0) {
System.out.println("Done");
} else {
System.out.println("Failed");
}
} catch (Exception ex) {
ex.printStackTrace();
}
你是否试过这样的事？ – Rocky 2012-02-01 10:09:23
