kandi X-RAY | jECAl Summary

jECAl is a Java library typically used in Programming Style, Aspect Oriented, Framework applications. jECAl has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

jECAl is a minimalistic Java framework to enable ECA rules (within Java code. Event-Condition-Action (ECA) rules are active rules as used in Event-driven architectures (and Active Databases systems (They typically consists of three parts: * the event, which identifies the signal that triggers the invocation of the rule, * the condition, which is a logical test that, if satisfied, causes the execution of the rule, * and the action, which consists in the sequence of operations to be applied on the local data. Please have a look at the use case provided as an example to get an intuition of the usefulness and the power of such kind of rules. As you will see, this implementation takes advantage of `Annotation`s and dynamic `InvocationHandler`s, much like many well known Aspect-oriented Programming (AOP) frameworks (Spring AOP, Google Guice, etc.). It was primarily intended for educational purposes so there is plenty of space for improvements; in particular, if you have constructive comments please reach out and let me know (rather than it would have been better if you had used feature X and Y of framework Z, because the idea since the beginning was to learn how these frameworks works).

QUESTION

@Recover method not intercepted by Spring AOP advice

Asked 2021-Jun-08 at 03:45

While writing code using Spring/Java and Aspect oriented programing, I'm facing an issue. In the service class, I have the retry method using @Retryable and a recovery method using @Recover.

Each of these 2 methods are attached to Aspects. The Retryable method - "triggerJob" inside TestProcessService is attached to these methods in TestAspect class - beforeTestTriggerJobsAdvice, afterTestTriggerJobsAdvice, onErrorTestTriggerJobsAdvice. They all are working fine and getting triggered at the right time.

PROBLEM STATEMENT: The Recovery method - "recover" inside TestProcessService is attached to these methods in TestAspect class - beforeRecoveryTestJobsAdvice, onErrorRecoveryTestTriggerJobsAdvice, and afterRecoveryTestTriggerJobsAdvice.

BUT NONE OF THESE ASPECT METHODS ARE GETTING CALLED once the code reached the recover method inside TestProcessService.

Here is the code:

SCHEDULER CLASS (triggers the methods inside TEST_MyProcessService class at regular interval)

I am not a Spring user, but interested in all things AOP, both AspectJ and Spring AOP. I liked your little puzzle. Thanks to your MCVE, I was able to reproduce the issue and debug into it. This is a perfect example for why an MCVE is so much superior to simply posting a bunch of code snippets. So thanks for that, please keep up this way of asking questions.

When looking at the situation in a debugger, you see that while the aspect is proceeding into triggerJob, at some point we are in method AnnotationAwareRetryOperationsInterceptor.invoke and there we have the following code:

QUESTION

Is it Possible to add PostSharp for dynamic compilation using c# compiler

Asked 2020-Aug-17 at 10:26

I am using Microsoft.CodeDom.Providers.DotNetCompilerPlatform nuget packge for compilation of code at runtime. It is achievable but in my scenario my dynamic class needs to use Postsharp for aspect oriented programming.

Can anyone point me to the commandline support to add Postsharp dependency injection for the compiled assembly using the csc.exe, like what is done by the MSBuild or Visualstudio.

...

ANSWER

Answered 2020-Aug-17 at 10:26

You can't easily do that with the current versions of PostSharp. The last version to have command-line execution is 5.0 and that is no longer supported.

The problem is that PostSharp reads too many properties in MSBuild or passed to it by MSBuild.

If it's possible for you to generate an msbuild file, you can then build it the Microsoft.Build NuGet package and have PostSharp run on the generated code that way.
