clojure alternative to AspectJ proxy in Java's code

2016-07-07 Thread Jacek Grzebyta 
Hi,

I have a Clojure project which strongly uses some external java framework
(if you want to know it is Eclipse RDF4j). I need to override some method
within a java class. The issue is I am not able to inject my own
implementation of that class because it is in the middle of some complex
hierarchy.

In another Java (+ Spring Framework) project I had similar problem and I
had fixed that using AspectJ proxy which had had a breakpoint in calling a
particular java method. I read in many places that Clojure does not need it
and some explanation based on pure clojure examples. I would like to know
if Clojure is able to manage java code.

Quite often examples built a proxy with combination Java Class + protocol
and than injected the instance into somewhere. I thing that it does not
cover following example. The problems I found difficult are:

1. Distance between my code and Foo class is like 3 or 4 classes
2. Programmers quite strongly uses creation de novo rather than injection
already prepared instance

Thanks a lot for your help,
Jacek Grzebyta



++ java code+

class Baz {

// I need to proxy this method
protected List doAction(String arg 1, String arg2)

// weird work which I need to change

}


 Foo class

class Foo {

// cut


// elswhere

Baz jobber = new Baz(); // it creates de novo injection not supported


public String mySuperMethod(List args4) {

jobber.doAction(someList)

}


// cut
}


++ end ++

Re: Can't extract multipart-params from POST request in compojure

You are right! I didn't set the boundary in my client code. Thanks a lot!
