Olá pessoal,
Nosso mapeamento consiste em um esquema de herança Tabela por Classe Concreta. Temos as tabelas TesteRange e TesteStep, e elas possuem campos em comum. Por isso temos as seguintes classes: Test, TestRange e TestStep.
As 2 ultimas classes extends de Test.
Nosso problema está em fazer o crud de forma genérica. Segue o controller:
@Resource
public class TestController<T extends Test> {
private ITestService<T> service;
private Result result;
public TestController(Result result, ITestService<T> service) {
this.result = result;
this.service = service;
}
@Path("/teste/add")
@Post
public void add(T test) {
service.saveOrUpdate(test);
}
}
Segue o service:
@Component
public class TestServiceImpl<T extends Test> implements ITestService<T>{
private ITestDao<T> daoTest;
@Override
public void saveOrUpdate(T test) {
try {
daoTest.saveOrUpdate(test);
} catch (Exception ex) {
System.out.println(ex);
}
}
}
Segue o DAO:
@Component
public class TestDaoImpl<T extends Test> extends GenericDaoImpl<RangeTest> implements ITestDao<RangeTest>{
public TestDaoImpl(Session session) {
super(RangeTest.class, session);
}
}
Com esse nosso DAO supostamente genérico, onde está especificado gostaríamos que fosse um , pois dessa forma conseguiríamos abordar tanto o StepTest qto o RangeTeste.
Porém com o DAO acima aparece o seguinte erro:
