HATEOAS Links on Spring Framework #pathvariable Map argument fails

HATEOAS Links on Spring Framework #pathvariable Map argument fails - java

I am writing a ReST API using Spring-mvc and Spring hateoas framework. I am trying to create a 'self' Link to a method that has #pathvariable Map as parameter. I am tying to allow multiple pathvariables (and it may grow in future) for the method and within the method I am trying to resolve a separate path based on the presence or absence of a variable.It all works fine till I try to create a self link.
I am getting an exception
There was an unexpected error
type=Internal Server Error, status=500). No converter found capable of
converting from type
[#org.springframework.web.bind.annotation.PathVariable
java.util.Map] to type
[java.lang.String]
Here is my Method
#RequestMapping(value={"/subs","/masterclient/{masterclient}/subs"},
method = RequestMethod.GET)
public List<Jobs> getJobList(
#PathVariable Map<String, String> pathVariables,
#RequestParam(value="count", required = false) int count)
{
if (pathVariables.containsKey("masterclient"))
{
System.out.println("Master Client = " +
pathVariables.get("masterclient"));
}
else
{
System.out.println("No Master Client");
}
//Add a Link to the self here.
List list = new ArrayList<Jobs>();
list.add(linkTo(methodOn(ControllerJobs.class).getJobList(pathVariables, count)).withSelfRel());
return list;
}
The Exception stack trace is below

Spring Boot sporadic exception (... connection was aborted?)

I have a spring boot application running very well but sometimes an exception comes which crashes the app. The problem is that I have difficulties to understand the exception stack, cause it looks like one exception causes another etc.
Are there also any hints how to trace if further to understand what happens?

Drools won't working

I have some problem with Drools.
In my rule.drl file i have this rule,checking if Article exists in working memory
rule "rule-2"
//include attributes such as "salience" here...
agenda-group "article-numbers"
when
//condition
exists (Article())
then
System.out.println("bbbbb");
//actions
end
and in Java class i have method
public void orderArticles(Article a){
KieSession kieSession = kieContainer.newKieSession("sesija");
kieSession.insert(a);
kieSession.getAgenda().getAgendaGroup("article-numbers").setFocus();
kieSession.fireAllRules();
ar.updateBrojArtikala(a);
ar.updateDodatiArtikle(a);
System.out.println(a);
kieSession.dispose();
}
where i am accessing Drools,and inserting Article in working memory.But even with this simple rule,I get the following error:

meaning that I'm accessing index -15 of string,which I don't do at all(!)
When I'm debugging,it always stops at
KieSession kieSession = kieContainer.newKieSession("sesija");
and there breaks.
I think this is very strange,it seems like something is wrong with my settings or kieContainer..?Does anyone experienced something similar?I think that my settings are fine,but I don't know what could be a problem..Does someone have some suggestion how to solve this?Thanks in advance!:)

When I asked if that was your entire DRL, you were not supposed to lie :P
The application you posted in your comments includes 2 .drl files full of rules. One of this rules - update price for whole bill-1- contains a typo in its Right Hand Side. For some reason, Drools was choking when processing this line and generating an impossible to understand error.
The line I'm talking about is the following one:
modify($bill){setFinalPrice((int)(0.95*$bill.getFinalPrice())};
If you pay attention, there are 5 opening brackets ( but only 4 closing brackets ).
When adding the missing bracket, everything seems to work (or at least the rules compile OK):
modify($bill){setFinalPrice((int)(0.95*$bill.getFinalPrice()))};
Hope it helps,

In CrafterCMS, I have an issue seeing an mp4 video in Safari

In CrafterCMS, I have a mp4 video uploaded in static assets, I'm able to see it correctly in all browsers except Safari. When I request it like
http://localhost:8080/static-assets/videos/687898845.mp4
I only see the player:
If I play it, nothing happens.
I see this error in the log file:

Could it be that I'm missing something? Is this a safari issue? There's any workaround for this?

Usually, that kind of Files is served by apache.Apache is much better at serving static assets (like videos) than tomcat.
you can try to tweak some setting on the tomcat like changing the default HTTP connector to the NIO2 one Http11Nio2Protocol more on that here

Why am I suddenly getting an NPE on counters in Flying Saucer?

I have an html template that I have been using with Flying Saucer PDF since last November. I rebuilt the project recently and suddenly the same HTML and the same code is throwing an NPE. I narrowed it down to the page counters. When I remove them it works. Here is a sample of my html that demonstrates the issue.
<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<style type="text/css">
#page {
#top-right {
content: element(header);
}
}
#pagenumber:before {
content: counter(page);
}
#pagecount:before {
content: counter(pages);
}
</style>
</head>
<body>
<header id="header" class="clearfix">
<div class="page-header">
<span class="label">Order Status</span><br/>
Page <div id="pagenumber"></div> of <div id="pagecount"></div>
</div>
</header>
<div>Hello World</div>
</body>
</html>
I am sending that as the payload to a small webservice that uses flying saucer to render it and send it back. This is my code in the service:
#RequestMapping(value="/render", method= RequestMethod.POST)
public void renderPdf(#RequestBody String xhtmlContent, HttpServletResponse response) {
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(xhtmlContent);
renderer.layout(); //ERROR HAPPENS HERE
try {
response.addHeader("Content-disposition", "attachment;filename=invoice.pdf");
response.setContentType("application/x-octet-stream");
renderer.createPDF(response.getOutputStream());
} catch (Exception e) {
logger.error("Error creating pdf: ", e);
}
}
And I get the following stack trace:
java.lang.NullPointerException: null

Again, let me reiterate, this code worked before I tried to rebuild it. I did not change my flying saucer version, but I was using RELEASE as my version in Maven. So just to ensure there weren't issues I specified concrete version numbers going back to the date when it worked and a little before and it still happens.
As I post this I'm tracing through the source but haven't found anything yet.

The version 9.1.5 of flying saucer project fixed the problem.
The 9.1.4 is to blame.

Will #Transactional rollback if it fails before second transaction?

Does Spring transaction management rollback operations that succeeded before it fails whether or not it failed during a database operation? For example:
#Service
#Transactional
public class PurchaseInvoiceLineServiceImpl implements PurchaseInvoiceLineService {
#Autowired
private PurchaseInvoiceLineRepository purchaseInvoiceLineRepository;
#Autowired
private StockRepository stockRepository;
#Autowired
private PurchaseInvoiceRepository purchaseInvoiceRepository;
#Autowired
private SupplierDebtRepository supplierDebtRepository;
public <S extends PurchaseInvoiceLine> S save(S purchaseInvoiceLine) {
purchaseInvoiceLineRepository.save(purchaseInvoiceLine);
updatePurchaseInvoiceAmountForCreate(purchaseInvoiceLine);
// update stock
Stock stock = stockRepository.getStockByProduct(purchaseInvoiceLine.getProductId());
stock.setQuantity(stock.getQuantity().add(purchaseInvoiceLine.getQuantity()));
stockRepository.update(stock);
// update debt
PurchaseInvoice purchaseInvoice = purchaseInvoiceRepository.findOne(purchaseInvoiceLine.getPurchaseInvoiceId());
SupplierDebt supplierDebt = supplierDebtRepository.getDebtBySupplierId(purchaseInvoice.getSupplierId());
supplierDebt.setAmount(supplierDebt.getAmount().add(purchaseInvoiceLine.getLineAmount()));
supplierDebtRepository.update(supplierDebt);
return purchaseInvoiceLine;
}
}
Should #Transactional rollback the whole transaction if it fails at the following line (which is not a database operation)?
stock.setQuantity(stock.getQuantity().add(purchaseInvoiceLine.getQuantity()));
Update:
Because the table "stock" does not have any records, at // update stock, the stock object that is read is null, so a NullPointerException is thrown at the next line in which it tries to set the quantity. Here's the whole stacktrace:
java.lang.NullPointerException: null

Yes it will, according to the Spring documentation:
In its default configuration, the Spring Framework’s transaction infrastructure code only marks a transaction for rollback in the case of runtime, unchecked exceptions; that is, when the thrown exception is an instance or subclass of RuntimeException. ( Errors will also - by default - result in a rollback). Checked exceptions that are thrown from a transactional method do not result in rollback in the default configuration.
Given that your failure criteria is an unchecked exception.
Because you marked the class as #Transactional, as you invoke PurchaseInvoiceLineService.save() the proxy will start the transaction and if there was any exceptions with the method execution, catch them and rollback the transaction.

Depends - if the transaction was already started (implementation/bussiness logic dependent) it will be rolled back - but could be commited as well - with no operations.
Something has to be done with the transaction to release DB connection. Rolling back is the most common solution. More over it is most universal one as it will fit into most scenarios - even with nested and extended transactions.
