I'm using Sleuth 1.3.X to add distributed tracing feature to a microservice, I'm trying to change the Span name, and I came across this Link
It says that the SpanReporter should inject the SpanAdjuster and allow span manipulation before the actual reporting is done.
How I can do that?
here is my SpanAdjuster
#Bean
SpanAdjuster mySpanAdjuster(){
return (SpanAdjuster) span -> {
if ("/rest/XYZ/message".equals(span.tags().get("http.path"))){
Span.builder().from(span).name("Rest API").build();
}
return span;
};
}
You seems to be doing this as the docs suggests, check out the Sleuth auto-configuration, it should be injected, it might happen that you are using an incompatible version of another module/project, e.g.: Spring Boot.
Also, we are about to release Sleuth 3.1.0, you are two major versions behind, this version is not supported anymore, so even if this is a bug, there won't be a new release from the 1.x line that could fix this.

We developing a Spring Boot REST Application using Spring Data Neo4J. Recently we upgraded to Spring Data Neo4j 4.2 along with ogm 2.1.1 and using the embedded driver.
In our application we provide some GET operations in which we build some object structures from nodes fetched from Neo4j.
As soon as we are processing multiple requests in parallel, we are facing inconsitent results, i.e., our object structures have a different size on each request.
We are not really sure about the reasons for this inconsistent behavior - but probably it is related to the session handling in OGM? We know that Sessions are not thread safe, but we have no idea how to deal with this issue in SD 4.2. Before 4.2 we changed the sesssion scope to prototype when defining the session bean, but the configuration changed in SD 4.2
Configuration before 4.2
#Bean
#Scope(value = "prototype", proxyMode = ScopedProxyMode.TARGET_CLASS)
public Session getSession() throws Exception {
return;
}
We could narrow the source of our problems to the place where we are loading elements from Neo4j via a Repository class:
repository.findOne(id,-1);
If we place this call in a synchronized block, no inconsistencies occur.
synchronized (this) {
repository.findOne(id,-1);
}
We are probably missing some important point using SD 4.2/ogm, but could not find any useful information in the documentation, and on the web.
Is it still possible/necessary to change the sesssion scope in SD 4.2?
This is a bug in the OGM. See: https://jira.spring.io/browse/DATAGRAPH-951
We hope to have a fix for this in the next version (OGM 2.1.2).
This is what I get when I run atlas-create-jira-plugin followed by atlas-create-jira-plugin-module selecting option 1: Component Import.
The problem is that all tutorial examples appear to have plugin descriptor generated by old SDK version (that won't deploy with newer versions of SDK/Jira at all), which do not feature Atlassian-Plugin-Key, so I can't find my way to import a component.
I'm using SDK 6.2.3 and Jira 7.1.1.
Any hint - how to get this sorted out?
anonymous is correct. The old way of doing things was to to put the <component-import> tag in your atlassian-plugin.xml. The new way and also recommended is to use Atlassian Spring Scanner. When you create your add-on using atlas-jira-create-plugin and your pom.xml has the <Atlassian-Plugin-Key> tag and the dependencies atlassian-spring-scanner-annotation and atlassian-spring-scanner-runtime then you are using the new way.
If you have both the dependencies, you are using Atlassian Spring Scanner version 1.x. If you only have atlassian-spring-scanner-annotation then you are using version 2.x.
You don't have to omit/comment out Atlassian-Plugin-Key in your pom.xml and you don't have to put component-import in your atlassian-plugin.xml.
For example, you want to add licensing for your add-on and need to import the component PluginLicenseManager. You just go straight to the code and your constructor might look like this:
#Autowired
public MyMacro(#ComponentImport PluginLicenseManager licenseManager) {
this.licenseManager = licenseManager;
}
And your class like this:
#Scanned
public class MyMacro implements Macro {
If memory serves me right, be sure to check for null because sometimes Atlassian Spring Scanner can't inject a component. I think on version 1, writing an #EventListener, it could not inject a ConversionContext. But when writing a Macro, it was able to inject a ConversionContext.
According to
https://bitbucket.org/atlassian/atlassian-spring-scanner
component-import is not needed. You can replace it by #ComponentImport annotation in your Java.
Found answer here: https://developer.atlassian.com/docs/advanced-topics/configuration-of-instructions-in-atlassian-plugins
It looks like I've somehow been missing that Atlassian-Plugin-Key can be omitted, and it must be done when you need to import components.
This key just tells spring not to 'transform' plugin's Spring configuration, which must happen as part of components import process..
In the past I have been able to apply advice chain handlers on different outbound channel adapters. I am trying to do the same on int-aws:s3-outbound-channel-adapter but its not allowing that. Does this component not allows this behavior. Basically I am interested in finding out when the adapter completes the upload of a file to S3.
<int-aws:s3-outbound-channel-adapter
id="s3-outbound" channel="files" bucket="${s3.bucket}"
multipart-upload-threshold="5192" remote-directory="${s3.remote.dir}"
accessKey="${accessKey}" secretKey="${secretKey}">
THIS DOESNT WORKS - throws an error !!!
<int:request-handler-advice-chain>
</int:request-handler-advice-chain>
</int-aws:s3-outbound-channel-adapter>
Right, that isn't allowed by the XSD. Feel free to raise a JIRA on the matter.
But that doesn't matter that it doesn't work at all.
If you are on Spring Integration 4.x already you can move that <int-aws:s3-outbound-channel-adapter> to the Java & Annotation configuration using #Bean and #ServiceActivator for the AmazonS3MessageHandler.
Where #ServiceActivator has adviceChain attribute to specify bean references to your Advices.
... or you can do that using generic <int:outbound-channel-adapter> and specify AmazonS3MessageHandler as raw <bean> for the ref of the first one.

I have been trying to refactor our Activiti implementation into using CDI but ran into a number of problems. I've spent way too much time trying to resolve this already, but I just can't let it go...I think I've pinned the problem down now, setting up a clean structured war without involving Activiti and have been able to reproduce what I think is the main problem.
Basically I have jar1 and jar2, both CDI enabled by including META-INF/beans.xml. Both jars specify a class in META-INF/services/test.TheTest pointing to implementations local to respective jar. jar1 depends on jar2. Also, both jars point to an implementation of javax.enterprise.inject.spi.Extension, triggering the scenario. In each implementation of Extension, I have a method like:
public void afterDeploymentValidation(
#Observes AfterDeploymentValidation event, BeanManager beanManager) {
System.out.println("In jar1 extension");
ServiceLoader<TheTest> loader = ServiceLoader.load(TheTest.class);
Iterator<TheTest> serviceIterator = loader.iterator();
List<TheTest> discoveredLookups = new ArrayList<TheTest>();
while (serviceIterator.hasNext()) {
TheTest serviceInstance = (TheTest) serviceIterator.next();
discoveredLookups.add(serviceInstance);
System.out.println(serviceInstance.getClass().getName());
}
}
Now, my problem is that the ServiceLoader does not see any implementations in either case when running WebLogic12c. The same code works perfectly fine in both Jboss 7.1.1 and Glassfish , listing both implementations of the test.TheTest interface.
Is it fair to assume that this is indeed a problem in WebLogic 12c or am I doing something wrong? Please bare in mind that I am simply trying to emulate the production setup we use when incorporating Activiti.

There is a Classloader Analysis Tool provided with WLS, have you seen if this will help with the diagnosis of your issue.
You can access this tool by going to ip:port/wls-cat/index.jsp
Where port will be the port of the managed server where your application is deployed.
I've been banging my head at this for about 8 hours now, and I just can't seem to find a simple explanation on how to change my custom bootstrapper for ninject (Last worked on the code back in v2.x.x.x) to the new v3.0.0.0 syntax.
I currently have the following:
public class NinjectCustomBootStrapper : NinjectNancyBootstrapper
{
protected override Ninject.IKernel GetApplicationContainer()
{
return Program.MyContainer;
}
}
in a septate class, and :
public static IKernel MyContainer
{
get { return _myContainer ?? (_myContainer = CreateKernel()); }
set { _myContainer = value; }
}
private static IKernel CreateKernel()
{
var kernel = new StandardKernel();
kernel.Bind<CardMonitorService>().ToSelf().InSingletonScope();
return kernel;
}
in my main program 'Program.c' in a command line app.
Iv'e since updated ninject to V3.0.0.0 only to find that there's been some breaking changes. I'll admit I don't use ninject very often (I usually use structuremap), and the only reason this project does is I didn't write it originally.
Since I've upgraded Ninject, now when the app is started up I get the following exception:
Method not found: 'Ninject.Syntax.IBindingWhenInNamedWithOrOnSyntax`1<!0>
Ninject.Syntax.IBindingToSyntax`1.ToConstant(!0)'.
After a ton of searching and researching, the closest I've been able to find is this:
http://sharpfellows.com/post/Ninject-Auto-registration-is-changing-in-version-3.aspx
Which while it points me in the right direction, still isn't quite a solution as I'm not using a custom binding generator.
So my question is this.
How do I rewrite the above so that my project once again works and the WCF service when called gets the correct singleton binding handed to it when a request comes in. Going back to ninject 2 is not an option, as other dependencies in the project that have been added have forced the v3 upgrade and these add new functionality that's been requested hence why I'm working on it.
For reference this is a .NET4 build, running on NancyFX with a self hosting WCF setup as a windows service using Topshelf to provide the SCM interface.

Addendum to clear things up a little
This is an existing project that was originally written sometime back, I've been asked to add some new features to the project.
As part of adding these new features I have been required to upgrade the version of Ninject being used from an earlier version to V3.0.0.0 as newer dependencies added to the project require the newer version of Ninject.
Under the previous V2 of Ninject the code I have given above worked fine, with no issues, since the project has had Ninject V3 added I now get the exception as described above.
I cannot go back to the earlier version of Ninject as that will mean not being able to add the new functionality that I'm adding.
From the research I've done so far the sharpfellows link above is the closest explanation of my issue that I've managed to find so far on the internet.
I don't use Ninject very often, so I've not got the background to know what's changed between V2 & V3 that (based on my research) is the cause of my issue.
I need to know how to change my code written under V2 (and shown above) so that it works under V3.
MissingMethodException is usually a deployment problem. You compile against a different assembly than you deploy. Check that you deployed the same version and same build.
So after a week or so it turns out that the problem was that the Nancy dev team broke binary comparability with the latest version of ninject (or vice versa) :-)
There is a GitHub pull request to fix this available at :
https://github.com/NancyFx/Nancy.Bootstrappers.Ninject/pull/6
However the next version 'Nancy.Bootstrapper.Ninject' 0.12 will be out on NuGet soon which will have the fix implemented.
