我有一个TextHistory实体对象，然后我有这个JPA查询。
SELECT NEW TextHistory(i.id, i.fileName, i.importDate) FROM TextHistory i")
在实体对象中，我提供了相应的构造函数。
我正在尝试在Payara 4.1下部署我的应用程序，但是我在部署时遇到了这个例外：
Error occurred during deployment: Exception while deploying the app
[app-name] : Exception [EclipseLink-28019]
(Eclipse Persistence Services - 2.6.2.qualifier):
org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description:
Deployment of PersistenceUnit [unit-name] failed.
Close all factories for this PersistenceUnit. Internal Exception:
Exception [EclipseLink-0] (Eclipse Persistence Services - 2.6.2.qualifier):
org.eclipse.persistence.exceptions.JPQLException
Exception Description: Internal problem encountered while compiling
[SELECT NEW TextHistory(i.id, i.fileName, i.importDate) FROM TextHistory i].
Internal Exception: java.lang.NullPointerException.
Please see server.log for more details.
我认为我的JPA查询语法是正确的。 我现在已经挣扎了好几个小时了。
有什么问题？有什么想法吗？
在server.log中，我看到了这个异常。

答案 0 :(得分：3)
为什么你真的想要使用SELECT NEW语法的任何提示？ 此语法主要用于（罕见）您希望从一个实体中选择字段并使用这些字段的值构建不同对象的情况。
在您的情况下，您正在构建您选择的同一个实体。这通常以select e from SomeEntity e完成。 （实际上，与SQL相比，在JPQL中，select子句是可选的，只要您从单个实体中进行选择。from SomeEntity e只选择整个表，from SomeEntity e where e <whatever>选择全部<whatever>条记录。）
如果实体具有一些您不想最初加载的重量级属性（如@Lob s）或@ManyToOne关联，则执行此操作的正确方法是使它们延迟加载。对于LOB，这可以通过@Basic(fetchType = LAZY)完成，也可以通过@ManyToOne(fetchType = LAZY)完成。请注意，对于@ManyToMany和@OneToMany，延迟加载是默认值。
我的印象是你正在尝试做JPA“SQL方式”。一个可靠的SQL知识是正确使用JPA的必要条件，但是你需要始终从关系到面向对象的角度进行“范式切换”，以便按照预期的方式做事。
BTW，关于
我甚至不知道Eclipselink是什么
这几乎说明了一切:-) JPA是一个标准化的Java API - 它定义了事物应该如何工作，不多也不少。它实际上并没有真正的工作 - 这留给了特定的JPA实现，即a.k.a。持久性提供程序。有很多JPA实现，其中最突出的是Hibernate和Eclipselink。每个Java EE应用程序服务器都需要包含JPA持久性提供程序，看起来您的服务器附带了Eclipselink。当Oracle将其名为TopLink的专有JPA实现捐赠给Eclipse Foundation时，Eclipselink就出现了。
更新：我做了一些研究，看起来你的错误的原因很平常：SELECT NEW语法要求你使用构造函数的完全quialified名称，即包括包名。这是因为你可以select new进入你想要的任何POJO类，它不需要该类成为JPA实体。相反，from子句使用简单名称，因为那里只允许@Entity个类（JPA在部署时枚举和解析）。
为什么不使用完全限定名称导致Eclipselink代码中的NullPointer，这是另一个故事 - 似乎是Eclipselink中的一个错误。
==＆GT;这导致了哪个更好，select new或延迟加载的问题。一如既往，这取决于您的用例。无论对象如何进入内存，都将始终对延迟加载的字段进行注释。例如，使用EnitytManager.find（）始终返回实体的完整实例，使用时不能使用自定义构造函数。但是，关于领域的注释当然适用。通过关联访问实体时也是如此 - 如果A包含对B的引用，并且您调用A.getB()，则会根据其注释初始化B实例。< / p>
使用select new是一种一次性技术，以防您故意转移默认设置。
答案 1 :(得分：0)
不熟悉此org.eclipse.persistence.exceptions.EntityManagerSetupException语法，但可以看到您正在使用Eclipselink（http://wiki.eclipse.org/EclipseLink/Examples/JPA）
大约一年前，我遇到了一个问题，在一天结束时，它似乎是一个Eclipselink错误。值得检查（https://bugs.eclipse.org/bugs/query.cgi），也许它已经知道或者你刚刚找到它。
另一个猜测：<a>
可能会导致EntityManager的设置不正确。
