Subject: [sca-j] NEW ISSUE: SCA
Spring C & I specification does not state whether Constructor Injection
should be supported

 

Raiser:

Target:        sca-springci-draft-20070926.doc

Description: 

 

The SCA Spring Client and Implementation specification is silent on whether the
Spring Constructor Injection should be supported or not. 

Basically
Spring supports two types of Dependency Injection(DI) techniques 1) Setter
Injection and 2) Constructor Injection. 

1)
Setter Injection: In which the dependent module exposes a setter method which
the framework uses to inject the dependency, the current specification supports
this as shown below... by injecting the SCAReference using the setter method.

<bean
id="Y" class"org.xyz.someapp.SomeOtherClass">

 
  <property name="bar" ref="SCAReference"/>

</bean>

2)
Constructor Injection: In which the dependencies are provided through the class
constructor. The Specs remains silent on whether this should be supported or
not. 

<bean
id="Y" class"org.xyz.someapp.SomeOtherClass">

 
    <constructor-arg ref="SCAReference"/>

</bean>

Proposal:
None. 

Thanks
& Regards,

R Ramkumar
