Accessing DAO Service methods from non managedbeans

I am using Spring 3 and Hibernate 4

How can I use the following in a non ManagedBean 

@Inject 
EmployeeService employeeService

Or if I would want to access DAO method I have to make that a ManagedBean as

@Named("mymanagedbean")
@ViewAccessScoped

I have a few Converter class and in order to access DAO service methods I had to use that as ManagedBean even though they are not ManagedBeans.

What is the best approach to call DAO service methods?

Thanks

Solution

  • You will need to implement the Spring interface ApplicationContextAware and then set the ApplicationContext. Then you need provide static methods to get the bean instance. 

    public class SpringApplicationContext implements ApplicationContextAware {

private static ApplicationContext CONTEXT;

public void setApplicationContext(ApplicationContext context)
        throws BeansException {
    CONTEXT = context;
}
    public static Object getBean(String beanName) { ...}
    public static <T> T getBean(Class<T> arg0) {...}

    Then in your non-managed bean you can call SpringApplicationContext.getBean method by passing in EmployeeService.class as the argument or the bean name as the argument.
