Customizing an existing Alfresco class

[ALfreSara]

Hello,

my objective is customizing an existing Alfresco class instead of changing directly in the org.alfresco:

the solution was "creation of a custom content store implementation that inherit from StoreSelectorAspectContentStore and register you implementation in spring configuration extension", I did that but my problem is thatI I dont know how to register my implementation in spring configuration extension.

thank you for your help.

You can define a bean named fileContentStore in your spring context file ,alfresco will use your fileContentStore implementation to override it's default.
Like following

    <bean id="fileContentStore" class="Your StoreSelectorAspectContentStore  implementation">
 ....
    </bean>

Thank you for reply,

after adding the bean here is the error displayed:

StoreSelectorAspectContentStore has a storesByName property dependency  which should be injected by constructor in your spring content-store-selector-context.xml file.
