Prototype Scoped Component

Question

Is is possible to create prototype scoped component in JIRA plugin? My intention is to create a different object on each dependency injection. Spring prototype scope seems to be intended for that reason. But annotation

value = ConfigurableBeanFactory.SCOPE_PROTOTYPE, proxyMode = ScopedProxyMode.TARGET_CLASS)@Scope(

doesn't seems to have any effect on a component, which is effectively stays "singleton" (checked at runtime through ApplicationContext.isPrototype(String name)).

Well, I've come with next solution. Let's say, we want to define class com.example.proto.MyProtoBean as prototype bean. 1. We need to explicitly define Spring Context within "plugin-context.xml" file. In conjunction with atlassian-spring-scanner-2 settings it should look something like this:

2. Important detail is to exclude given package from atlassian-spring-scanner plugin index: otherwise, it's going to be parsed as singleton bean. You can exclude package with in plugin configuration: com.atlassian.plugin atlassian-spring-scanner-maven-plugin ${atlassian.spring.scanner.version} atlassian-spring-scanner process-classes -com.example.proto.* 3. For prototype class it is enough to define @Scope annotation with value "prototype": @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE) public class MyProtoBean { // ... } 4. Finally, inject bean in another class with ObjectFactory: import com.example.proto.MyProtoBean; import org.springframework.beans.factory.ObjectFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Component public class ProtoUser { private final MyProtoBean myProtoBean; @Autowire public ProtoUser(ObjectFactory protoFactory) { this.myProtoBean = protoFactory.getObject(); } } You can use other ways to inject prototype beans into a singleton instance, although I didn't test them.
