java - nullPointerException when injecting bean with Spring -

java - nullPointerException when injecting bean with Spring -

i'm new spring 3.2.5 , i'm trying inject bean in 1 property, when want utilize property it's null.

i'm using next configuration:

applicationcontext.xml:

<bean id="subscriptionservice" class="fake.services.subscriptionservice"> </bean> <bean id="restcontroller" class="fake.restcontroller"> <property name="subscriptionservice" ref="subscriptionservice"></property> </bean>

restcontroller.java:

@path("/") @secured("role_user") public class restcontroller { protected isubscriptionservice subscriptionservice; /** * @return subscriptionservice */ public isubscriptionservice getsubscriptionservice() { homecoming subscriptionservice; } /** * @param subscriptionservice subscriptionservice set */ public void setsubscriptionservice(isubscriptionservice subscriptionservice) { this.subscriptionservice = subscriptionservice; } }

isubscriptionservice.java:

public interface isubscriptionservice { public uuid subscribe(); }

subscriptionservice.java

public class subscriptionservice implements isubscriptionservice { /** * */ public subscriptionservice() { } /** * subscribes user , returns uuid queue * @return uuid queue */ public uuid subscribe() { homecoming uuid.randomuuid(); } }

what missing?

thanks!

update:

the error i'm getting:
