爲什麼org.jasypt.exceptions.EncryptionOperationNotPossibleException

這裏是我的加密器類方法：爲什麼org.jasypt.exceptions.EncryptionOperationNotPossibleException

public String encrypt(String str){ 
     if(str == null || str.equals("")){ 
      str = ""; 
     } 
     else{ 
      StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor(); 
      encryptor.setPassword(mpCryptoPassword); 
      str = encryptor.encrypt(str); 
     } 
    return str; 
    } 
    public String decrypt(String str){ 
     if(str == null || str.equals("")){ 
      str = ""; 
     } 
     else{ 
      StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor(); 
      decryptor.setPassword(mpCryptoPassword); 
      str = decryptor.decrypt(str); 
     } 
    return str; 
    }

我試圖加密如下：

String encryptedToken = ""; 
//preparing token email + time 
Date now   = new Date();    
String prepareToken = "email="+email+"&tokenTime="+now.getTime(); 

//encrypt url value 
Encryptor enc  = new Encryptor(); 
encryptedToken  = enc.encrypt(prepareToken);

，我喜歡解密：

Encryptor enc   = new Encryptor(); 
String decryptedToken = enc.decrypt(encryptedToken);

那麼它的投擲錯誤：

更新
我注意到它的某個工作，但時有加密的字符串作爲其獲得+作爲空間

的問題，我發現是加+在加密的字符串登錄+號不工作。當我解密時，它是從URL中獲取空白的。

encryptedToken = encryptedToken.replaceAll(" ","+");

解決這個問題
