Caros amigos,
Estou com erro estranho na inicialização do Tomcat. Minha aplicação usa Spring MVC com DAO genérico. Estendi o conceito de DAO genérico para Service genérico, ou seja, tenho um Service genérico ( com método genérico - CRUD) que tem os outros Services que estendem este Service genérico. Este Service genérico depende do DAO genérico que possui outros DAOs que o estendem. Pois bem o meu problema está na injeção do DAO da classe Usuario no Service da classe Usuario. O DAO está anotado como Repository (ou seja um bean) o Service anotado como serviço. No log de DEBUG do Tomcat os beans são criados mas há erro na injeção. O qu estou fazendo de errado??? :(
Erro
