Can I use springboot annotations like #Bean, #Component, #Autowired etc in plain java project with just using gradle dependencies?
To use spring frameworks annotations the project should be either spring boot or a project with all the required spring dependencies to support the above mentioned annotations.
No. Spring uses those annotations for the inversion of control. Without this framework they are useless in plain java.

I think you are looking for #PostUpdate.Here is an example how to use the various lifecycle methods of JPA
I know a way to see XML based configuration dependency graph (Spring Tool Suite) but that does not work for annotations such as #Autowired and application separated in maven modules. Is there any way we can see that at project level or module level?
The beans dependency graph feature in Spring IDE doesn't support non-XML-based Spring definitions.
There is a "live beans graph" feature that visualizes all the beans in a running Spring application. Maybe that helps in your case.
I am looking at Spring documentation to learn Spring integration with Hibernate using annotation based spring configuration.
The documentation link is here.
Now the docs tell about how to configure Spring with Hibernate using xml files and there is no where mentioned how to use annotations for integrating Spring and Hibernate.
Please help me where can I find the explanation on Spring with Hibernate integration using annotations.
You can find the required annotations here - Annotations used for configuring DAO or Repository classes
Here is a good example for using Spring with Hibernate - Spring Hibernate Integration Using Annotations
http://examples.javacodegeeks.com/enterprise-java/hibernate/hibernate-jpa-dao-example/
I'm not sure if I should downvote you - you could easily find it on your own.
Ok, maybe it is not exactly Spring + Hibernate, but it really does not matter.
I am trying to use Enunciate to generate static documentation for my REST API that is written in Java using Spring MVC 3.2. The Enunciate website claims that it has Spring support by using a specific plugin here :
http://enunciate.codehaus.org/module_spring_app.html
When looking at the configuration options, it looks like I am supposed to import a spring applicationContext.xml. I use the annotation-based configuration for this project, so I don't have an applicationContext.xml. Is there a way to make this work in my case?
Thanks in advance for any help.
Enunciate currently supports Spring Web annotations.
Is it possible to inject Spring beans into an RestEasy #Path class? I managed to do it with Jersey, with #InjectParam annotation, but for some other reasons, I need to switch to RestEasy, and I can't seem to find a way to do it (tried good ol' javax.inject.Inject, but nothing).
EDIT
This solution works:
http://www.mkyong.com/webservices/jax-rs/resteasy-spring-integration-example/
but it's not injection.. I'd still prefer something a little more elegant.
Simply annotate your RestEasy class with Spring's #Component and then inject your beans using Spring's #Autowired. Don't forget to include the annotation-config and component-scan elements in your spring configuration.
There is a working example that integrates RestEasy with Spring just try spring-resteasy.
You could use the #Configurable annotation to make a normal class (created by new) a spring Bean.
Then you can use the normal Spring annotation to inject everything in that class/instance like in a "normal" Spring Bean.
But that requires AspectJ!
#See Spring Reference Chapter 7.8.1 Using AspectJ to dependency inject domain objects with Spring
I totally agree with Peter's answer but there is another way to do it: you make all your exposition beans (RESTEasy or JAX-WS, which are not Spring components) extending the SpringBeanAutowiringSupport.
That way you can easily inject your Spring Services by #Autowired annotation in these classes.
