[JBoss JIRA] Created: (JBIDE-8198) Support @Exact annotation
by Alexey Kazakov (JIRA)
Support @Exact annotation
-------------------------
Key: JBIDE-8198
URL: https://issues.jboss.org/browse/JBIDE-8198
Project: Tools (JBoss Tools)
Issue Type: Sub-task
Components: cdi (jsr-299)
Reporter: Alexey Kazakov
Assignee: Alexey Kazakov
Fix For: 3.3.x
2.2. @Exact
Annotating an injection point with @Exact allows you to select an exact implementation of the injection point type to inject. For example:
interface PaymentService {
...
}
class ChequePaymentService implements PaymentService {
...
}
class CardPaymentService implements PaymentService {
...
}
class PaymentProcessor {
@Inject @Exact(CardPaymentService.class)
PaymentService paymentService;
...
}

[JBoss JIRA] Created: (JBIDE-8200) Support @FullyQualified annotation

Support @FullyQualified annotation
----------------------------------
Key: JBIDE-8200
URL: https://issues.jboss.org/browse/JBIDE-8200
Project: Tools (JBoss Tools)
Issue Type: Sub-task
Components: cdi (jsr-299)

Fix For: 3.3.x
2.5. @FullyQualified bean names
According to the CDI standard, the @Named annotation assigns a name to a bean equal to the value specified in the @Named annotation or, if a value is not provided, the simple name of the bean class. This behavior aligns is with the needs of most application developers. However, framework writers should avoid trampling on the "root" bean namespace. Instead, frameworks should specify qualified names for built-in components. The motivation is the same as qualifying Java types. The @FullyQualified provides this facility without sacrificing type-safety.
Seam Solder allows you to customize the bean name using the complementary @FullyQualified annotation. When the @FullyQualified annotation is added to a @Named bean type, producer method or producer field, the standard bean name is prefixed with the name of the Java package in which the bean resides, the segments separated by a period. The resulting fully-qualified bean name (FQBN) replaces the standard bean name.
package com.acme;
@FullyQualified @Named
public class NamedBean {
public String getAge() {
return 5;
}
}
The bean in the previous code listing is assigned the name com.acme.namedBean. The value of its property age would be referenced in an EL expression (perhaps in a JSF view template) as follows:
#{com.acme.namedBean.age}
The @FullyQualified annotation is permitted on a bean type, producer method or producer field. It can also be used on a Java package, in which case all @Named beans in that package get a bean name which is fully-qualified.
@FullyQualified
package com.acme;
If you want to use a different Java package as the namespace of the bean, rather than the Java package of the bean, you specify any class in that alternative package in the annotation value.
package com.acme;
@FullyQualified(ClassInOtherPackage.class) @Named
public class CustomNamespacedNamedBean {
...
}
