NEW ISSUE: SCA Spring C & I specification should use "id" of the bean touniquely identify a bean instead of its name

Raiser:   Ramkumar Ramalingam

Target:  sca-springci-1.1-spec-WD02.pdf

Description:

The SCA Spring Client and Implementation
specification should use bean "id" attribute to uniquely identify
the bean from the application context instead of relying on the "name"
attribute (which can have multiple names for the same bean).

Some text from the specs:

95         Each
<service>
element used with <implementation.spring>
should include the name of the 

96         Spring
bean that is to be exposed as an SCA service in its name attribute.  So,
for Spring, the 

97         name
attribute of a service plays two roles: it identifies a Spring bean, and
it names the service 

98         for
the component.  The service element above has a name of “X”, so
there should be a Spring 

99         bean
with that name.  The SCDL also contains the <reference> element
named “SCAReference”.  

100         The
reference name becomes an addressable name within the Spring application
context – so, 

101         in
this case, “SCAReference” can be referred to by bean “Y” in the Spring
configuration above.

286         If
there are no <sca:service/> elements in the application context,
then services are defined by each of

287        the
top-level <bean/> elements in the application context:

288         If
there are no <sca:service/> elements in the application context,
one <service/> element exists for each 

289        service
implemented by each top-level <bean/> element in the application
context, found by introspection 

290        of
the bean class declared by the bean element, where:

291        @name
attribute value is the value of the @name attribute of the <bean/>
element

From the text shown above, the specs is
relying on the name attribute of the bean to define the service name in
case of implicit services. 

The name attribute of the bean can have
multiple alias separated by space, comma or semi-colon as per the spring-beans.xsd
(http://www.springframework.org/schema/beans/spring-beans.xsd).

Proposal:

The specs should use "id" attribute
of the bean to uniquely identify the bean within the application context
and define the service name using the value of the "id" attribute
of the <bean/> element.
