java - Spring file upload in a mixed form -


I want to upload a file in my spring 3.0 application (made with cry).

I already have the following unit: 

  @Antity @ RUJAVABIAN @ RUTHOSTRING @ RUNTTT Public Class Selenimphile {@ManyToOne (TargetIntytti = Showcase.Class) @ Zone Column Private Showcase Showcase; @ Lab @basic (fetch = fetchType.LAZY) private byte [] file; Name of the @notational private string; }

but I'm not sure how to implement it / execute on the controller side. Can I do & lt; Input type = file ... & gt; & lt; with normal tags like Form: input & gt; I can mix spring-form tags independently

I have seen good in MVC-documentation but still need some help to apply it in my specific case.

Update: I think my question was badly prepared. What I wanted to do is make the spring

I came to know how to do this in the old Spring Documents and how it has been implemented in the new Spring 3.0 MVC. Basically it means that you have to register a PropertyEditor in your controllers @InitBinder method. Afterwards everything will behave as expected (provided you have added multipartolarolor to the context and set the correct form encoding). Here's my sample: @RequestMapping ("/ scriptfile / **") @ Controller Public Class ScriptFileController {// We need special property-editor who knows how to pair data // Request a byte [] @InitBinder Public Zero InitBinder (WebDataBinder Binder) {binder.registerCustomEditor (Byte []. Category, New ByteArmaltpaintFile Editor ()); } @RequestMapping (value = "/ scriptfile", method = RequestMethod.POST) public string (@ Valid ScriptFile scriptfile, binding result result, ModelMap modelMap) {if (scriptfile == empty) remove new invalid bizarre conclusion ("require a scriptfile is" ); If (result.hasErrors ()) {modelMap.addAttribute ("scriptFile", scriptfile); ModelMap.addAttribute ("Shows", ShowCase.findAllShowCases ()); Return "script file / create"; } ScriptFile.persist (); Return "redirect: / scriptfile /" + scriptFile.getId (); }}

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
