Hi All,
Can you please explain me this one, I have confusion which
one is better.
1.
Bean<MyBean> bean = (Bean<MyBean>)
beanManager.resolve(beanManager.getBeans(MyBean.class));
MyBean= (MyBean) beanManager.getReference(bean,
bean.getBeanClass(),
beanManager.createCreationalContext(bean));
This one gives you a new instance of a client proxy. The client
proxy will forward method calls to the current contextual instance
of a particular context. You can therefore obtain the proxy once and
keep it and the method calls will be invoked on the current instance
(e.g. current request). It is also useful if the contextual instance
is not serializable - the client proxy will be and will reconnect
after you deserialize it.
2.
Bean<MyBean> bean = (Bean<MyBean>)
beanManager.resolve(beanManager.getBeans(MyBean.class));
MyBean bean =
beanManager.getContext(bean.getScope()).get(bean,
beanManager.createCreationalContext(bean));
This obtains the target instance without a client proxy. You may
still see a Weld's proxy in the class name but that is an enhanced
subclass that provides interception and decoration. If the bean is
not intercepted nor decorated this will be a plain instance of the
given bean.
Usually (1) is more suitable unless you have a special use-case
where you need to access the target instance directly (e.g. to
access its fields).
As i know BeanManager.getReference() always creates a
whole new proxy instance, while the Context.get() reuses an
existing proxy instance if already created before.
Is BeanManager.getReference() is more use full than
Context.get() ??
Thanks
