我有使用Struts2动作类进行登录验证的代码,该动作类调用EJB进行LDAP验证,然后验证(LDAP凭证),查询用户数据库以使用JPA实体bean获取其余的用户信息. POJO.与用户名,用户ID和其他用户信息不同,密码不存储在数据库中,但是为了POJO getter和setter方法,我尝试包含一个虚拟密码字段 - 用于提供Struts2操作表单.

问题是在ldap身份验证之后,发生了一个异常,说明数据库中不存在"密码"列(无论如何都不是这样!)

Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.0.1.v20100213-r6600): org.eclipse.persistence.exceptions.DatabaseException

这是实体bean的代码:

我需要转换Hibernate条件查询,如下所示

curList = session.createCriteria(Islem.class)
                    .createAlias("workingDay", "d")
                    .setProjection(Projections.sum("amount"))
                    .add(Restrictions.eq("currency", CURRENCY))
                    .add(Restrictions.eq("product", product))
                    .add(Restrictions.ne("status", INACTIVE))
                    .add(Restrictions.eq("d.status", ACTIVE))
                    .getResultList();

然而在JPA(2)中,我不知道如何实现投影 - 在这种情况下 - 总和.奇怪的是,Hibernate和JPA(甚至是Hibernate JPA 2)在标准查询中存在巨大差异.

我开始

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Islem> cq = cb.createQuery(Islem.class);
Root<Islem> isr = cq.from(Islem.class);
cq.select(isr).where(cb.equal(isr.get("currency"), CURRENCY), 
                     cb.notEqual(isr.get("status"), INACTIVE),
                     cb.equal(isr.get("product"), product));

但是不知道如何在这里实现投影既不是别名

是否必须在使用注释和hibernate配置文件之间做出严格的选择,或者是否可以在同一个项目中同时使用这两种方式？

我们有一个大型项目,完成Hibernate 3.2.5和配置.hbm.xml文件的POJO .该项目使用Hibernate SessionManagerFactory而不是基于JTA的EntityManager工厂.

这种方式配置了超过一百个POJO,原始开发团队不愿意切换到注释.

同时我们需要使用更多的POJO来扩展项目,我们愿意使用Hibernate注释来配置这些POJO,并希望继续使用Hibernate - 如果可能的话 - 而不是切换到JPA.

是否可以同时.hbm.xml为某些POJO 使用配置文件和其他POJO的注释组合？

我找不到这个问题的答案,这也是许多其他论坛上的问题.虽然我在数据库中存在表IAS_FORM_BKT_BAYI和IAS_FORM_BKT_BAYI_SO,但带有带注释的实体类(异常下面的源代码)我在基于JSF和Hibernate的应用程序中遇到了这个异常:

我有以下Hibernate 3.x Criteria Query,我想将它转换为Hibernate JPA 2.0查询:

Calendar calLo = new GregorianCalendar();
calLo.set(Calendar.HOUR_OF_DAY, 00);
calLo.set(Calendar.MINUTE, 00);
calLo.set(Calendar.SECOND, 00);
Calendar calHi = new GregorianCalendar();
calHi.set(Calendar.HOUR_OF_DAY, 23);
calHi.set(Calendar.MINUTE, 59);
calHi.set(Calendar.SECOND, 00);

List taskList = session.createCriteria(Task.class, "task").add(Restrictions.ge("task.taskDate", calLo.getTime())).add(Restrictions.le("task.taskDate", calHi.getTime())).add(Restrictions.eq("task.taskActive", true)).addOrder(Order.desc("task.taskNo")).list();

我尝试重新开始代码,例如:

CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery cq = cb.createQuery(Task.class);
Root task = cq.from(Task.class);
cq.select(task).where(cb.ge("task.taskDate", calLo.getTime()) ... );

但JPA 2标准查询似乎不支持CriteriaBuilder.ge(...)方法接受日期或日历作为输入参数,我的代码似乎从一开始就失败了.

我需要建议来保留和调整Hibernate会话标准的功能.
