我使用
spring jpa Activiti vaadin ……

无法自动加载MyServiceImp！

当我新的对象然后：

EntityManager中的NullPointerException

MyServiceImp：

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import ru.xpoft.test.Repository.Product;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

@Service
@Transactional
public class MyServiceImp {

    @PersistenceContext(unitName = "Product")
    private EntityManager entityManager;

    public Boolean CreateProduct(String PrdctName, String PrdctNameId) {
        try {  
            Product Product = new Product(PrdctName, PrdctNameId);
            System.out.println("Ok1");
            entityManager.persist(Product);
            System.out.println("Ok2");
            return true;
        } catch (Exception e) {
            System.out.println(" error in my service ::" + e.toString());
            return false;
        }

    }
}

我的问题在哪里？
当我在diable< validation-mode> NONE< / validation-mode>错误：
无法构建EntityManagerFactory
和
无法构建默认的ValidatorFactory
和……
谢谢

最佳答案 有关验证模式文档,请参见
http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html/configuration.html.

您遇到的错误表明您在类路径中没有符合JSR303的bean验证程序.你是如何建立考试的？您需要确保将适当的hibernate-validator拉入类路径. (请注意,验证器的版本与hibernate-core的版本不同.)

无效的原因是它禁用了查找bean验证器.
