我正在尝试在DepartmentService中注入DepartmentDAO。这是在我添加@Transactional注释后出现的。所以这是我的DepartmentService：
@Service
@Transactional
public class DepartmentService extends AbstractCRUDService<DepartmentDTO> {
private DepartmentDAO departmentDAO;
public DepartmentService() {
super();
this.departmentDAO = null;
}
@Inject
public DepartmentService(DepartmentDAO departmentDAO) {
super();
this.departmentDAO = departmentDAO;
}
@Override
public Long create(DepartmentDTO dDTO) {
Department department = new Department();
department.setDepName(dDTO.getDepName());
return departmentDAO.create(department);
}
...............read,update,delete,findAll methods...........................
}
这是我的部门代码：
@Repository
@Transactional(propagation = Propagation.MANDATORY)
public class DepartmentDAO extends AbstractCRUDDao<Department> {
private final Logger logger = LoggerFactory.getLogger(DepartmentDAO.class);
protected Class<DepartmentDAO> clazz;
public DepartmentDAO() {
}
@Override
public Long create(Department d) {
entityManager.persist(d);
return d.getId();
}
...............read,update,delete,findAll methods...........................
}
这是一个applicationContext.xml：
