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.
