Calling custom method from core interface

Question

I am extending a DbNodeServiceImpl class and try to Override a method named public void setProperty(NodeRef nodeRef, QName qname, Serializable value).

When I am trying to call the method with the help of nodeService interface its calling the default method that is present in DbNodeServiceImpl, not the custom one that i created. How can I implement the same thing? I just want to call my own method with the help of nodeservice Interface.

How are you creating the instance used to call the method? It should be using an instance like this `NodeService s = new WhateverClassThatExtendsDbNodeServiceImpl()` — dambros, Apr 20 '16 at 11:06
no i am not instantiating i am just injecting the nodeservice and call that method with the help of that injection. i am just using the refrence of nodeservice s and calling like s.setproperty(x,y,z) — Sachin Singh, Apr 20 '16 at 11:48
private NodeService nodeService; public void setNodeService(NodeService nodeService) { this.nodeService = nodeService; } — Sachin Singh, Apr 20 '16 at 11:58
can any one tell where nodeservice bean or nodeserviceimpl bean is defined in alfresco? — Sachin Singh, Apr 21 '16 at 07:14

You should define your own class like this:

   <bean id="newOwnService" class="MyNewServiceImpl" init-method="init" parent="org.alfresco.repo.node.db.DbNodeServiceImpl" >
         .... some needed properties....

       </bean>

Then where you call your method:

<bean id="newClass" class="NewClass">
        <property name="somethingName" ref="newOwnService"/>
       </bean>

In code:

private NodeService somethingName;

public setSomethingName(NodeService somethingName){
    this.somethingName = somethingName;
}

The interface calls overridden method with same signature. You cannot override a method two times in same implementor class.You should post some code for better explanations

actually i have a class that extend the DbNodeServiceImpl.class and DbNodeServiceImpl class implement nodeservice interface. i want override a method that defined in nodeservice and implemented in DbNodeServiceImpl but when i am calling that method its calling method that is present in DbNodeServiceImpl class not mine. – Sachin Singh Apr 20 '16 at 11:02
without seeing the code i think you are calling the method on a reference of type DbNodeServiceImpl , not on the other class that extends DbNodeServiceImpl. Show me the specific call instruction – Homo Filmens Apr 20 '16 at 11:13
public class CustomGetProperties extends DbNodeServiceImpl { public void setProperty(NodeRef nodeRef, QName qname, Serializable value) throws InvalidNodeRefException { if(dictionaryService.getType(qname).equals(DataTypeDefinition.ENCRYPTED)){ApplicationContext ctx =ApplicationContextHelper.getApplicationContext(); MetadataEncryptor metadataEncryptor = (MetadataEncryptor)ctx.getBean("metadataEncryptor"); Serializable encryptedValue=metadataEncryptor.encrypt(qname,value); super.setProperty(nodeRef,qname,encryptedValue); } else super.setProperty(nodeRef, qname, value); – Sachin Singh Apr 20 '16 at 11:23
i am not taking refrence here i am just extending – Sachin Singh Apr 20 '16 at 11:24
super.setProperty.... is a direct call to parent class, in this example DbNodeServiceImpl . Your method always returns a call to DbNodeServiceImpl setProperty method – Homo Filmens Apr 20 '16 at 11:27
yes i want to call that parent class method but before that i want to set encrypted value according to my requirment that thing i impplemented in my method – Sachin Singh Apr 20 '16 at 11:33
@SachinSingh read my comment on the question and show how you are calling instanciating the nodeService. – dambros Apr 20 '16 at 11:41
