javax.persistence.EntityManager.getCriteriaBuilder（）Ljavax /持久/标准/ CriteriaBuilder [英] javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria/CriteriaBuilder
问题描述
我使用Hibernate 4，Spring 3和JSF 2.0以及Weblogic 10.3.6
我在DAO类中有以下内容：
CriteriaBuilder cb = entityManager.getCriteriaBuilder（）;
CriteriaQuery<请求> c = cb.createQuery（Request.class）;
当我运行我的应用程序时，出现以下异常。
javax.persistence.EntityManager.getCriteriaBuilder（）Ljavax / persistence / criteria $ b $ / CriteriaBuilder;
java.lang.NoSuchMethodError：
javax.persistence.EntityManager.getCriteriaBuilder（）Ljavax / persistence / criteria $ b $ / CriteriaBuilder;
at net.test.request.dao.RequestDAOImpl.getRequest（RequestDAOImpl.java:51）
我没有使用JPA1罐子，但是我仍然得到这个异常。无法确定如何摆脱此异常。任何帮助都非常可观。
谢谢

方法 EntityManager.getCriteriaBuilder 是JPA 2（它是Java EE 6的一部分）的一部分，它在WebLogic 10中未默认提供和/或打开。
以下链接 http://docs.oracle。 com / cd / E17904_01 / web.1111 / e13720 / using_toplink.htm ，其中提供了可能解决您的问题的说明。如果没有，您需要开始使用Google搜索weblogic 10 jpa 2，并查看是否可以找到适合您的解决方案。
如果这些解决方案均不起作用，您最后的选择是重新设计您的应用程序，只使用JPA 1方法。要使用JPA 1，您必须将自己限制为以下定义的类和接口： http://docs.oracle.com/javaee/5/api/javax/persistence/package-summary.html
[更新]
或者 - 因为无论如何你都在使用Hibernate，所以不要太依赖于JPA类。改为使用hibernate特定的类。自3.x起，Hibernate已经有了标准。您可以创建一个Hibernate会话工厂，而不是一个EntityManager。然后你可以这样做：
pre $ import $ org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
...
会话会话= sessionFactory.openSession（）;
Criteria crit = session.createCriteria（Person.class）;
您的代码现在被锁定为使用Hibernate作为持久性提供程序。在我的情况下，我们总是使用Hibernate，所以它不是一个真正的问题。这是你必须为自己决定的问题。如果您的应用程序可以容忍被锁定到Hibernate中，这应该会为您提供在WebLogic上运行时所需的功能。
I am using Hibernate 4, Spring 3 and JSF 2.0 and Weblogic 10.3.6 I have the following in DAO class
CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery<Request> c = cb.createQuery(Request.class);
When I run my application I am getting the following exception.
javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria
/CriteriaBuilder;
java.lang.NoSuchMethodError:
javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria
/CriteriaBuilder;
at net.test.request.dao.RequestDAOImpl.getRequest(RequestDAOImpl.java:51)
I did not use JPA1 jars, however I am still getting this exception. Not able to figure how to get rid of this exception. Any help is highly appreciable.
Thanks

The method EntityManager.getCriteriaBuilder is a part of JPA 2 (which is part of Java EE 6), which is not provided and/or turned on by default in WebLogic 10.
Here is a link http://docs.oracle.com/cd/E17904_01/web.1111/e13720/using_toplink.htm which provides instructions that may fix your problem. If not, you'll need to start googling "weblogic 10 jpa 2" and see if you can find a solution that works for you.
If none of these solutions work, your last resort will be to redesign your application to only use JPA 1 methods. To use JPA 1 you must limit yourself to the classes and interfaces defined here: http://docs.oracle.com/javaee/5/api/javax/persistence/package-summary.html
[update]
Or - since you are using Hibernate anyways, don't rely so much on JPA classes. Use hibernate specific classes instead. Hibernate has had criteria since 3.x. Instead of an EntityManager you create a Hibernate session factory. Then you can do:
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
...
Session session = sessionFactory.openSession();
Criteria crit = session.createCriteria(Person.class);
Your code is now locked into using Hibernate as your persistence provider. In my case we always use Hibernate so it's not a real problem. This is a question you have to decide for yourself. If your application can tolerate being locked into Hibernate, this should give you the functionality you need while still running on WebLogic.
