Hi guys, I want to migrate many of my old xml spring configuration files to java annotations, and just leave there the complex configuration files.

The problem is that I'm not able to migrate the classes that I must extend to create a DAO implementation. Have tried lot of things about injecting a superclass property without success.

These are my configuration xml files...
Code:
<bean id="CountriesDAO" class="com.citigroup.latam.edelivery.sm.database.oracle.OracleCountriesDAO">
    <!-- This one is a superclass property -->
    <property name="dataSource" ref="RoutingDataSource"/>
</bean>
<bean id="RoutingDataSource" class="com.citigroup.latam.edelivery.sm.database.RoutingDataSource" >
    <property name="targetDataSources">
        <map>
	     <entry key="${database.ar.name}" value-ref="DataSourceBeanAR"/>
             <entry key="${database.mx.name}" value-ref="DataSourceBeanMX"/>
        </map>
    </property>	      	   
</bean>
These are my java files...
Code:
public class OracleCountriesDAO extends JdbcDaoSupport implements CountriesDAO {
    public Map<T> getAll() {...}
    //... all CRUD methods ...//
}
Code:
public class RoutingDataSource extends AbstractRoutingDataSource {
    @Override
    protected Object determineCurrentLookupKey() {
        return  DAOContextHolder.getCurrentSchema();
    }
}
Until here everything work fine.
But now, I want to annotate DAOs, so have removed the xml bean CountriesDAO and left RoutingDataSource (this one is an inherited property from JdbcDaoSupport).
I have tried the following java files...
Code:
@Repository
public class OracleCountriesDAO extends JdbcDaoSupport implements CountriesDAO {
        @Autowired
	public OracleCountriesDAO (RoutingDataSource routingDataSource){
		super.setDataSource(routingDataSource);
	}
}
Code:
@Repository
public class OracleCountriesDAO extends JdbcDaoSupport implements CountriesDAO {
        @Autowired
	public setRoutingDataSource (RoutingDataSource routingDataSource){
		super.setDataSource(routingDataSource);
	}
}
Actually, have tested all I found in forums but nothing worked and the following error appears all the time...
Injection of resource fields failed; nested exception is java.lang.NoSuchMethodError: org.springframework.core.MethodParameter.getParame terAnnotations()[Ljava/lang/Object;
Have no idea how to fix this. The only clue I have, it's that have decompiled JdbcDaoSupport class and its method setDataSource is a final one, below is its signature:
public final void setDataSource(DataSource dataSource)

So guys, anybody can help me with this? Can't figure it out and it's very frustrating.
Hope to posted clear.
Thanks in advance.
