【问题描述】：
我无法发现为什么我的带有 objectify 的集成测试会崩溃。 逐一执行或调试都没有问题。
那是物化代码。
protected void before() throws Throwable {
original = ObjectifyService.factory();
ObjectifyFactory factory = newObjectifyFactory();
for (Class<?> type : register) {
factory.register(type);
}
ObjectifyService.setFactory(factory);
closeable = ObjectifyService.begin();
}
protected void after() {
ObjectifyService.setFactory(original);
closeable.close();
}
经过一些测试，跑步者停下来，我收到了这条消息。

【问题讨论】：
-
你也可以为“newObjectifyFactory()”添加代码吗？为什么要创建新工厂，将工厂重置为原始工厂的原因是什么？
-
这里是代码：protected ObjectifyFactory newObjectifyFactory() { return new ObjectifyFactory();但这是我在研究中发现的一个尝试解决问题的示例。在我只是使用 ObjectifyService.register() 之前；'和“ObjectifyService.begin();”。够了，但是报错是一样的。
