i am using spring 3, and i have two beans of view scope:
1- Bean1:
@Component("bean1")
@Scope("view")
public class Bean1 {
@Autowired
private Bean2 bean2;
}
2- Bean2:
@Component("bean2")
@Scope("view")
public class Bean2 {
@Autowired
private Bean1 bean1;
}
the view is a custom scope:
<bean class="org.springframework.beans.factory.config.CustomScopeConfigurer">
<property name="scopes">
<map>
<entry key="view">
<bean class="${project.groupId}.utils.ViewScope" />
</entry>
</map>
</property>
</bean>
and here's the code for the custom view scope:
public class ViewScope implements Scope {
@SuppressWarnings("rawtypes")
public Object get(String name, ObjectFactory objectFactory) {
Map<String, Object> viewMap = FacesContext.getCurrentInstance()
.getViewRoot().getViewMap();
if (viewMap.containsKey(name)) {
return viewMap.get(name);
} else {
Object object = objectFactory.getObject();
viewMap.put(name, object);
return object;
}
}
public Object remove(String name) {
return FacesContext.getCurrentInstance().getViewRoot().getViewMap()
.remove(name);
}
public String getConversationId() {
return null;
}
public void registerDestructionCallback(String name, Runnable callback) {
// Not supported
}
public Object resolveContextualObject(String key) {
return null;
}
}
when opening the page that uses both beans, i get the exception:
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'agencyBean': Requested bean is currently in creation: Is there an unresolvable circular reference?

please advise how to fix this exception.
EDIT: i tried to use the setter injection as referenced in the answer here
Understanding Spring context initialization order
but it doesn's work too.
1- Bean1:
@Component("bean1")
@Scope("view")
public class Bean1 {
private Bean2 bean2;
@Autowired
public void setBean2 (Bean2 bean2) {
this.bean2= bean2;
}
}
2- Bean2:
@Component("bean2")
@Scope("view")
public class Bean2 {
private Bean1 bean1;
@Autowired
public void setBean1 (Bean1 bean1) {
this.bean1= bean1;
}
}
but it gives me the exception:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.myapp.beans.Bean1] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}
I think you could use Spring's
@Lazy
annotation on one of the autowired fields to break circular dependency.
I'm not sure if this works/exists in mentioned Spring version.
