Springframework Failed to parse configuration class on a controller

Question

I am working on a j2ee project with eclipse, maven and spring. All is going quite fine except a weird and annoying behavior i can't resolve...

Let's begin with the stacktrace :

After some search on google i found it can be related to a classpath problem, so there is my Build path (can't post pictures ...):

In source folder build path : intranetLTTD/src/main/java Included : All Excluded : none

and my project treeview :

Java Ressources - src/main/java -com.lttd.controller -FichiersController

So it don't seems to be a classpath issue.

I also found on google that the "$1.class" means its an anonymous class... why not but i don't make it from my own, ( i don't even know how to make it for a controller ).

This error is happening when i make any change in my FichiersController ( like declare a variable ) but also when i make any change in a controller i created after my FichiersController, but not in the ones i created before.

I found a workaround to still be able to run the project ( and it's a weird workaround ) : after making a change, i have to change in one of my method of the FichiersController :

TypeFichier fileType = TypeFichier.valueOf(fileTypeString);
switch(fileType)

to :

switch(TypeFichier.valueOf(fileTypeString))

Or reverse

switch(TypeFichier.valueOf(fileTypeString))

to

switch(fileType) 

And in my dispatcher-servlet.xml i have :

<context:component-scan base-package="com.lttd" />

I hope i've gave all you need to help me find out whats happening, and how to resolve it. Don't hesitate to ask for further informations.

Thanks for your help.

Answer 1

Maybe you solved it already but I just Had the same problem with strange $1.class and for me that was a problem with Eclipse's publishing so I just built my web project with maven and put manually the files into my tomcat folder.

Answer 2

EDIT : found the cause of the problem : <context:component-scan base-package="com.lttd" /> was present in dispatcher-servlet.xml , but also in my spring-security.xml (due to the fact i was learning j2ee spring at the beginning of the project). That's why it created a FichierController$1. But i don't know why it happens with this class only.

After deleted the <context:component-scan base-package="com.lttd" /> in spring-security.xml, i don't have the problem anymore.

EDIT: Finally this did not repaired the error, the error reappeared 3 days later...

Here is the method of the FichiersController i have to edit for a temporarily workaround :

    @Transactional
    @RequestMapping(value = "/admin/fileEditAjax*", method = RequestMethod.GET)
    public @ResponseBody FichierFormObject fileEditAjax(@RequestParam (value="fileName", required = true) String fileName,
                                                    @RequestParam( value="fileType", required = true)String fileTypeString){

        FichierFormObject fileFormObject = new FichierFormObject();
        TypeFichier fileType = TypeFichier.valueOf(fileTypeString);

        //If the error is triggered, i have to change this 'switch(fileType)' to TypeFichier.valueOf(fileTypeString) or reverse
        switch(fileType){
            case FICHE_CONNEXION:
            case DOCUMENT_CLIENT:
                //some processing
                break;

            case PROCEDURE:
                //some processing
                break;

            case MODULEM3:
                //some processing
                break;

            case PRODUIT_CONNEXE:
                //some processing
                break;

            default:
                break;
        }

        return fileFormObject;
    }

But i'm not sure the problem comes from my code...

Hope this edit is the right place to add those information.
