的東西與我的數據庫恢復計劃會錯,這個錯誤隱藏我的幸福:產生java.io.IOException:不能運行程序「的MySQL」:CreateProcess的錯誤= 2,系統找不到指定的文件

產生java.io.IOException:不能運行程序「的MySQL」:CreateProcess的錯誤= 2, 該系統找不到指定的文件

文件要恢復位於d:當我/Backup/backup.sql瀏覽並從此路徑打開文件,然後單擊恢復按鈕時出現錯誤。請幫我解決這個問題。下面是 是我的代碼JFileChooser用於瀏覽文件位置。

browseButton.addActionListener(new ActionListener(){ 

public void actionPerformed(ActionEvent event){ 

    String recPath = ""; 
     JFileChooser fc = null; 
     if (fc == null) { 
      fc = new JFileChooser(); 
      fc.setFileSelectionMode(JFileChooser.FILES_AND_DIRECTORIES); 
      fc.setAcceptAllFileFilterUsed(false); 
    } 
    int returnVal = fc.showDialog(null, "Open"); 
    if (returnVal == JFileChooser.APPROVE_OPTION) { 
     File file = fc.getSelectedFile(); 
     recPath = file.getAbsolutePath(); 

     sourceField.setText(recPath); 


    } 

} 

} 

); 


recoveryButton.addActionListener(new ActionListener(){ 

public void actionPerformed(ActionEvent event){ 

    try{ 

     String databaseName ="jdbc:mysql://localhost:3306/myDB"; 
     String userName  ="abc"; 
     String password  ="123"; 
     String source  = sourceField.getText(); 
     int processComplete; 

     String[] executeCmd = new String[]{"mysql",databaseName, "--user=" + userName, "--password=" + password, "-e", "source"+source}; 

     //sava the command in a array 
     Process runtimeProcess = Runtime.getRuntime().exec(executeCmd);// execute the command 

     processComplete = runtimeProcess.waitFor();// get the result to variable 

     if(processComplete==1){ 
     JOptionPane.showMessageDialog(null, "Restore Failed"); 
     } 

     else if(processComplete==0){ 

     JOptionPane.showMessageDialog(null, "Restore Completed"); 

     } 

     } 
     catch(Exception ex){ 

     JOptionPane.showMessageDialog(null,ex); 

     } 

     } 


} 


);

您應該添加路徑 'MySQL的' 進入 '路徑' 變量或指定代碼完整路徑:

嘗試

String[] executeCmd = new String[]{"\FULL PATH HERE\mysql",databaseName, "--user=" + userName, "--password=" + password, "-e", "source"+source}; 

,而不是

String[] executeCmd = new String[]{"mysql",databaseName, "--user=" + userName, "--password=" + password, "-e", "source"+source};
