某人？

如果您坚持使用您需要的

org.datanucleus : datanucleus-core, datanucleus-api-jdo v3.1.x
com.google.appengine.orm : datanucleus-appengine v2.1.x

增强时添加到datanucleus enhancer v3.1.x（除非通过maven插件完成）

我在Eclipse中通过输入project properties-Google-App Engine并将datanucleus JDO/JPA版本从unspecified切换到2来克服这个错误（跟踪转储顶部的错误是java.lang.ExceptionInInitializerError，如果这很重要的话）

如果有点晚了，很抱歉，但我已经在一些项目中使用了GAE，并且每次都会遇到此错误，因为文档中很容易遗漏此错误

在应用程序

war/WEB-INF/classes/META-INF/

目录中，创建一个名为

jdoconfig.xml

的文件，该文件包含以下内容：

<?xml version="1.0" encoding="utf-8"?>
<jdoconfig xmlns="http://java.sun.com/xml/ns/jdo/jdoconfig"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="http://java.sun.com/xml/ns/jdo/jdoconfig">

<persistence-manager-factory name="transactions-optional">
    <property name="javax.jdo.PersistenceManagerFactoryClass"
        value="org.datanucleus.api.jdo.JDOPersistenceManagerFactory"/>
    <property name="javax.jdo.option.ConnectionURL" value="appengine"/>
    <property name="javax.jdo.option.NontransactionalRead" value="true"/>
    <property name="javax.jdo.option.NontransactionalWrite" value="true"/>
    <property name="javax.jdo.option.RetainValues" value="true"/>
    <property name="datanucleus.appengine.autoCreateDatastoreTxns" value="true"/>
    <property name="datanucleus.appengine.singletonPMFForName" value="true"/>
</persistence-manager-factory>

这将指定名为“transactions optional”的JDOperationResistenceManagerFactory实例

在谷歌文档中-

您发布的内容中没有NoClassDefFoundError。这是由以下原因引起的：javax.jdo.JDOFatalUserException:必须指定名为javax.jdo.Pe RSistenceManager FactoryClass的属性，或者必须在类路径中指定名为javax.jdo.option.PersistenceManager Factory项的jar文件，或者指定名为javax.jdo.option.PersistenceUnitNam的属性必须指定e。那么为什么不遵循消息？或者也许你只是不发布重要信息？嗨，比利，谢谢你的关注，我对此感到非常困惑，对不起。好吧，我今天开始了另一个项目。现在我发现了一个错误org.datanucleus.api.jdo.jdopersistencemanagerfactory没有找到我编辑了thacer和pom.xml。可以吗你又看到了吗？
