我正在尝试使用 Spring4gwt 集成 Spring 3、Jpa 和 Gwt ，但是当 spring 尝试创建 Bean 、我的 xml 和下面的错误堆栈跟踪时出现异常：

注意：我没有使用 Maven

道：

@Repository("customerDAO")

公共类 CustomerDAO 扩展 JpaDAO {

@PersistenceUnit(unitName = "amine")
EntityManagerFactory EntityManagerFactory;

@PostConstruct
public void init(){


    super.setEntityManagerFactory (EntityManagerFactory);
}



public abstract class JpaDAO<K, E> extends JpaDaoSupport {
protected Class<E> entityClass;

@SuppressWarnings("unchecked")
public JpaDAO() {
    ParameterizedType genericSuperclass = (ParameterizedType) getClass()
            .getGenericSuperclass();
    this.entityClass = (Class<E>) genericSuperclass
            .getActualTypeArguments()[1];
}

public void persist(E entity)  {
    getJpaTemplate().persist(entity);
}

服务：

@RemoteServiceRelativePath("springGwtServices/customerService")
public interface CustomerService extends RemoteService

服务实现：

@Service("customerService")


public class CustomerServiceImpl implements CustomerService {

@Autowired
private CustomerDAO CustomerDAO;

@PostConstruct
public void init() throws Exception {
}

@PreDestroy
public void destroy() {
}

错误日志：

可能您的 persistence.xml 文件放置不正确，因此无法在类路径中找到。

它应该放在 META-INF 文件夹中。
