orm - How to query a date in HQL (Hibernate) with Joda Time? -

-

I'm sure anyone is familiar with HQL (I'm a newbie myself) can easily answer this question .

In my Grails application, I have the following domain class. 

  class book {org.joda.time.DateTime releaseDate // I use PersistentDateTime to continue through hibernate (which is a DATETIME type in my HQL query, I I want to retrieve the books which are included in the date range of the release  date1  ..  date2  
  Date Book date 1, Date 2 ... def queryStr = "Book with 'b * where b.releaseDate & gt; $ date1 and B.releaseDate & lt; $ date2" def res = Book.executeQuery (queryS Tr)  
 
 but I have exceptions  ... due to: org.springframework.orm.hibernate3.HibernateQueryException: unexpected token:  error token digits in date format ( For example  2009-11-27T21: 57: 18.010 + 01: 00  or  no thank you V 27 22:01:20 CET 2009 ) 
 
 I also tried to convert date 1 to a date range without success 
 
 So what is the correct HQL code? Do I use a pattern format method to specify a specific format (which is one?). In Should I change or is there another scalar method to do this? 
 
 Thanks, 
 
 Fabian.

I'm not a Grails expert, but in Java, you usually have date1 and Bind to the date2 query parameter and like this: 

  string HKL = "Select * b * where b.releaseDate & gt;: date1 and B.release date & lt ;: DATE2 "; Session.createQuery (hql) .setDate ("date1", date1) .setDate ("date2", date2) .list ();

I'm sure you can do something in grails. If not, then do not format your dates as yyyyMMdhhmms (no spaces) and attach them to single quotes - thus hibernating considers them as stability and MySQL dates them But will convert on.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
