java - Use of Spring Assert.notnull in production code -

-

I have found an application that uses spring alluring and every Autowold constructor Assert.notNull () process.

How can I not see how constructor autovirings make these arguments unusable, so these arguments seem to be redundant and the code has to be confused.

I appreciate that this unit may be useful for testing where ARG is manually injected, but I think the NPE in the probe will be sufficient enough to indicate that The test has not started properly.

Before I go and the 'clean' code I thought I would just ask if I remember something? I think this is just extra prevention - a feature of the automaker's container, which is different from your code and can be disabled at any time, in this way you can clearly define the contractor's contract.

Let's say someone has disabled the autoworker on that particular class and has changed it with: 

  & lt; Bean id = "myBean" class = "com.my.company.BeanImpl" & gt; & Lt; Constructor-arg name = "some services" & gt; & Lt; Null / & gt; & Lt; / Creator-arg & gt; & Lt; / Bean & gt;   
 I think this is the issue you are missing :)

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
