Spring XML config to JavaConfig: inheritance and bean dependency -

i have list of services extend abstractservice class. abstractservice holds dao (you can call "repository") , has getter/setter dao:

/**  * @param <t> entity type  * @param <k> entity id type  * @param <s> dao type  */ public abstract class abstractservice<t, k extends serializable, s extends basedao<t, k>> implements baseservice<t, k> {     private s dao;      public s getdao() { return dao; }      public void setdao(s dao) { this.dao = dao; }      // common methods services, using dao, instance      @override     public optional<t> findone(k key) throws dataexception {         return optional.ofnullable(dao.findone(key));     } } 

a service example:

@service public class employeeserviceimpl extends abstractservice<employee, integer, employeedao> implements employeeservice {     // specific methods service } 

the related dao (i use spring data jpa):

public interface employeedao extends basedao<employee, integer> { } 

extending

@norepositorybean public interface basedao<t, k extends serializable> extends jparepository<t, k> { } 

by way added annotations @service , @norepositorybean while moving javaconfig.
old xml config was:

<bean id="com.xxx.service._abstractservice" abstract="true" class="org.springframework.transaction.interceptor.transactionproxyfactorybean">     <property name="transactionmanager" ref="com.xxx.dao._txmanager" />     <property name="transactionattributes">         <props>             <prop key="save*">propagation_required,-com.xxx.dataexception</prop>             <prop key="update*">propagation_required,-com.xxx.dataexception</prop>             <prop key="delete*">propagation_required,-com.xxx.dataexception</prop>         </props>     </property> </bean>  <bean id="com.xxx.service.employeeservice" parent="com.xxx.service._abstractbo">     <property name="target">         <bean class="com.xxx.service.employeeserviceimpl">             <property name="dao" ref="com.xxx.dao.employeedao"/>         </bean>     </property> </bean> 

first question, proper way inject generic dao , handle service inheritance using javaconfig?
second question, how translate xml snippet transactions (com.xxx.service._abstractbo) javaconfig?

here have far, 2 classes:

@configuration @componentscan("com.xxx.service") public class springconfig { } 

and persistence config

@configuration @enablejparepositories("com.xxx.repository") @enabletransactionmanagement public class persistenceconfig {     /* here far defined datasource, entitymanagerfactory,        platformtransactionmanager , jpavendoradapter */ } 

thanks in advance time!

here ended doing: instead of trying translate old xml config, changed classes design. since daos required anyway, inject them in each concrete class constructor calls new abstract class constructor added.

the abstract service:

final private s dao;  public abstractservice(s dao) {     super();     this.dao = dao; }  // getter protected , setter removed protected s getdao() {     return dao; } 

and concrete service example:

@service public class employeeserviceimpl extends abstractservice<employee, integer, employeedao> implements employeeservice {      @inject     public employeeserviceimpl(employeedao dao) {         super(dao);     } } 

the thing didn't have change java config posted in question, meaning @enablejparepositories("com.xxx.repository") , @componentscan("com.xxx.service") sufficient generate , bind beans.
