Text after 

  class ExtHotelApiService HotelApiService {static scope =" singleton "static behavior = true def save (parameter) {parameter extends is. Hotels.each {ht-> Try {transactionalSave (HT)} hold (exception e) {dealing / * exception *}}} @transactional (only read = false, promotional = Propagation.REQUIRES_NEW, rollBackFor = RollBackError.class) DEF transactionalSave (HT) RollBackError {throws 
 
     
  1.  ExtHotelApiService extends  HotelApiService  
    2.  
  2.  RollBackError extends  RuntimeException  
    3.  
  3.  ExtHotelApiService.transactional =  True  
    4.  
  4.  HotelApiService.transactional =  False < / Strong> 
    5.  
  5.  We must   save the hotel and save the details after that 
    6.  
  6.  We should  return  roll back the transaction (and not stay in the hotel) Details are not valid (can not be sustained) 
    7.  
 
 All code was written accordingly, but there is a problem - there is no roll back at all! : (
 
 The transaction is done successfully and the hotel is similar to DB, even after RollBackError is thrown 
 
 Where I make a mistake and how to correctly tell a narrative transaction To work with  
 
 
 Exception. The checked exceptions can be declared to trigger rollbacks, but if default @transaction related settings are retained, then a check exception will have no effect on the existing transaction. 
 
 The spring document is available on it, and relevant sections are 10.5.5, and 10.5.6, especially note the following: 
 
 
 runs any RuntimeException rollback , And no exceptions to any checks

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
