我的代码是：

"".equals(question.uniqueID)

其中question是模型，uniqueID是String。我正在使用Play框架1.2.6，这是完全出乎意料的。所以我要求我写一些更多的文字，所以我正在努力。

Answer 1

我的代码是：＆＃34;＆＃34; .equals（question.uniqueID）其中question是模型，uniqueID是String。

这与他的堆栈跟踪不匹配所以我不知道这是OOME的原因。

我使用的是Play框架1.2.6，这是完全出乎意料的。

你可以在任何系统中运行内存不足，特别是像Play这样的高级内存，所以不是那么出乎意料。我会尝试将最大堆大小增加到至少1 GB，如果不是16 GB（如果你有那么多）

OutOfMemoryError：超出GC开销限制
