Hibernate and Spring MVC. Transaction not working

Question

I get following error when I try use my DAO. I don know where is problem. I please for help.

Error look like this:

Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

This is my POJO class:

  @Entity
    @Table(name = "contacts")
    public class Customer {

        @Id
            @Column(name="ID")
            @GeneratedValue
            private Integer id;
            @Column(name="firstname")
            private String name;
            @Column(name="lastname")
            private String surname;
            @Column(name = "telephone")
            private String telephoneNumber;
            @Column(name = "email")
            private String email;

DAO class:

@Repository

public class CustomerResource implements DAO_INTERFACE {

    @Autowired
    private SessionFactory sf;


    @Override
    public void addCustomer() {


    }

    @Override
    public List<Customer> getList() {

        return sf.getCurrentSession().createQuery("from Customer").list();
    }

    @Override
    public void delete(int id) {

    } 
}

Service:

@Service
    public class CustomerService implements CustomerDatabaseInterface {

        @Autowired
        private DAO_INTERFACE customerRepo;

        @Transactional
        public List<Customer> getCustomers() {

            return customerRepo.getList();
        }
    }

servlet-context.xml:

    <resources mapping="/resources/**" location="/resources/" />

    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />

I am beginning programmer. I just learn hibernate and Spring.

Answer 1

You don't seem to have transaction management correctly configured for your spring application because you are scanning for everything in your dispatcher servlet.

 <context:component-scan base-package="pl.project" />

You might have duplicated beans in the component-scanning. Both component-scan elements ie in the dispatcher-servlet-context and the root-context detect the same elements hence instantiating your DAO service twice. Fix your component-scan elements by scanning only your controller classes in the dispatcher-servlet-context and excluding your controller classes from the component scan in the root-context, something like this

Dispatcher Servlet Context:

 <context:component-scan base-package="pl.project.controller" />

Root application context (Datasource context)

<context:component-scan base-package="pl.project">
        <context:exclude-filter type="regex" expression="pl.project.controller.*"/>
    </context:component-scan>

Answer 2

嗨，您应该在servlet-context.xml中保留与MVC相关的内容，例如视图和控制器，然后将服务和存储库移至root-context（application-context）。
