javax.persistence.EntityManager.getCriteriaBuilder()Ljavax / persistence / criteria / CriteriaBuilder

我正在使用Hibernate 4,Spring 3和JSF 2.0和Weblogic 10.3.6
我在DAO课上有以下内容

        CriteriaBuilder cb = entityManager.getCriteriaBuilder();
        CriteriaQuery<Request> c = cb.createQuery(Request.class);

运行我的应用程序时,出现以下异常.

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)

我没有使用JPA1罐子,但是仍然遇到此异常.无法弄清楚如何摆脱此异常.任何帮助都是非常明显的.

谢谢

最佳答案

方法EntityManager.getCriteriaBuilder是JPA 2(属于Java EE 6的一部分)的一部分,JPA 2在WebLogic 10中默认不提供和/或未打开.

这是链接http://docs.oracle.com/cd/E17904_01/web.1111/e13720/using_toplink.htm,其中提供了可以解决您的问题的说明.如果没有,您将需要开始搜索“ weblogic 10 jpa 2”,看看是否可以找到适合您的解决方案.

如果这些解决方案都不起作用,那么您最后的选择就是将您的应用程序重新设计为仅使用JPA 1方法.要使用JPA 1,您必须将自己局限于此处定义的类和接口：http://docs.oracle.com/javaee/5/api/javax/persistence/package-summary.html

[更新]

或者-因为无论如何您都在使用Hibernate,所以不要太依赖JPA类.请改用休眠特定的类. Hibernate从3.x开始就有标准.您可以创建一个Hibernate会话工厂,而不是EntityManager.然后,您可以执行以下操作：

import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

...

Session session = sessionFactory.openSession();
Criteria crit = session.createCriteria(Person.class);

现在,您的代码已被锁定为使用Hibernate作为持久性提供程序.就我而言,我们始终使用Hibernate,因此这不是一个真正的问题.这是您必须自己决定的问题.如果您的应用程序可以容忍被锁定在Hibernate中,那么这将为您提供仍在WebLogic上运行时所需的功能.
