I'm new comer for the spring-mvc. I tried to find good tutorial for develop test project using spring-mvc, hibernate, mysql and jsf. Finally I created sample project.

Here is capture of my project

My first question is,

Is this spring-mvc structure

But unfortunately it's show above error.

Please give me a answer. I tried this since long time. I can build project using spring. But I need to build with spring-mvc with @Autowired annotation.

Spring MVC and jsf are sort of competing technologies... Do you actually mix them? – Kukeltje
@kukeltje thank you. I don't know what are you saying me. I don't know more things about this. Am I wrong with this? – Priyantha

In ManagedBeanClass class you try to autowire a entity. Entitys are not autowire candidates.

Change the class to 

@Autowired
private Person person;

       to 

private Person person = new Person();

Yes you can use @Autowire to let spring create a prototype scoped instance of the entity. But it is dirty because a entity is neither a dependency nor a context for ManagedBeanClass, the entity is the model of ManagedBeanClass. A model is not a dependency because the ManagedBeanClass MUST be able to create its model by itself, not let spring handle it.

Anyway, you like to have this dirty solution.

Assuming the entity is in the package of com.journaldev, add this to the entity:

@Bean                                                         <-new
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)               <-new 

@Entity
@Table(name="PERSON")
public class Person {
