 }

 public String backup(String backupPath, String dbName) throws IOException {

  String backupFile = backupPath+ dbName+ new SimpleDateFormat("yyyy-MM-dd-HH-mm-ss").format(new Date()) + ".sql";

  String  = "mysqldump "+"--host="+serverUrl+" --user=" + username + " --password="+ password + " --opt " + dbName + "> " + backupFile;

  java.lang.Runtime.getRuntime().exec("cmd /c " + mysql);
  
  System.out.println("备份成功!");
 
  return backupFile;

 }

 public void restore(String restoreFile, String dbName) throws Exception {
 
  String mysql = "mysql "+"-h"+serverUrl+" -u" + username + " -p"+ password + " " + dbName + " < " + restoreFile;
 
        System.out.println(mysql);
