Spring mvc Mapeamento ambíguo encontrado. Não é possível mapear o método do bean do controlador
Estou tentando criar um aplicativo que possa listar alguns valores do banco de dados e modificar, adicionar, excluir, se necessário, usando o Spring 4 e receber o seguinte erro (somente se a anotação "@Controller" estiver presente nos dois arquivos do controlador, se eu excluir a anotação de um dos arquivos, ele funciona, mas recebo uma mensagem no console "nenhum mapeamento encontrado ... no dispatcherservlet com nome ...):
