Question

Resolution: No I’m no longer extending the original parent.

Original:
Is there a way to annotate an inherited final setter method? I am extending a class which has a final setter which I would like to @Autowire with Spring. The parent class is from a library and cannot be modified.

A workaround I have found is to write a proxy method, but this seems like more work than necessary.

public abstract class SqlMapClientDaoSupport ... {
    public final void setSqlMapClient(SqlMapClient smc) {
        ...
    }
}

@Component
public class AccountDao extends SqlMapClientDaoSupport {
    // all this just to annotate an existing method?
    @Autowire
    public final void setSqlMapClientWorkaround(SqlMapClient smc) {
        super.setSqlMapClient(smc);
    }
}

Edit 1: Above example modified to reflect use case:
The use case is implementing DAO objects for Ibatis/Spring
which extend a common base class. Each DAO needs the same
property set, and each needs to be configured as a bean. I currently
do this by configuring each individually in applicationContext.xml.

<bean id="accountDAO" 
  class="com.example.proj.dao.h2.AccountDAOImpl"
  p:sqlMapClient-ref="sqlMapClient" />
<bean id="companyDAO" 
  class="com.example.proj.dao.h2.CompanyDAOImpl"
  p:sqlMapClient-ref="sqlMapClient" />
<!-- etc... -->

I would prefer to use component-scan to discover and autowire the DAO
objects automatically, which I can’t copy/paste botch.

<context:component-scan base-package="com.example.proj.dao.h2" />

I do not see in the annotation guide how one would annotate a
property/member other than where declared. I’m hoping that is
something I’m missing though.

Edit 2: I am no longer extending the SqlMapClientDaoSupport class, instead my AccountDao is a POJO which implements what little functionality was being provided by the Support class. This allows me to use @Autowire at will.

Answer 1

No, there is no way to annotate an inherited final method.

Rather than extend the support class (SqlMapClientDaoSupport) I reimplemented it in my project (it’s behavior is minimal) annotating the methods as needed, and my DAO extend that support class.
