Spring Roo在Datanucleus+；谷歌应用引擎

spring google-app-engine jpa

Spring Roo在Datanucleus+；谷歌应用引擎,spring,google-app-engine,jpa,spring-roo,datanucleus,Spring,Google App Engine,Jpa,Spring Roo,Datanucleus,我正试图在datanucleus和AppEngine上开发SpringRoo项目。因此，我采取了示例gae expenses.roo来执行。在本地主机上运行它之后，我得到以下错误 （1） DataNucleus.的元数据中的元数据 com.username.server.domain.Report.approvedSupervisor:中出现错误 元数据：数据存储不支持联接，因此无法 接受将相关对象放入默认提取组的请求。 该字段将在首次访问时延迟获取。你可以修改这个 通过设置datanucleu

我正试图在datanucleus和AppEngine上开发SpringRoo项目。因此，我采取了示例gae expenses.roo来执行。在本地主机上运行它之后，我得到以下错误

（1） DataNucleus.的元数据中的元数据 com.username.server.domain.Report.approvedSupervisor:中出现错误 元数据：数据存储不支持联接，因此无法 接受将相关对象放入默认提取组的请求。 该字段将在首次访问时延迟获取。你可以修改这个 通过设置datanucleus.appengine.ignorableMetaDataBehavior发出警告 属性。值为“无”将使警告静音。A ERROR的值将把警告变成异常

（2） 第二个问题是CSS加载。有时它无法加载 CSS，甚至小图标。它需要刷新。我不知道背后有什么问题 那个

如果以前有人尝试过这个roo文件。。。我犯了以下错误

（3） 单击“创建新报告按钮”后。它提供数据访问 失败

数据访问失败很抱歉，访问数据库时出现问题

细节

检测到试图将报表（尚未有id）建立为的父级 雇员（5629499534213120），但由 员工（5629499534213120）已在没有 父母亲一旦创建了对象，就无法建立或更改父对象 一直坚持下去。；嵌套异常是 javax.persistence.PersistenceException:检测到试图建立 以员工（5629499534213120）的家长身份报告（尚未提供id），但 员工识别的实体（5629499534213120）已经 在没有父对象的情况下持续存在。无法建立或更改父级 一旦对象被持久化

这是我的pom.xml
