Spring Data JPA OutOfMemoryError：超出了GC开销限制

Question

我正在开发一个具有大量实体的应用程序（3072）。 我们使用jhipster进行项目结构。 到目前为止，Everthing还可以，直到我们想要将Spring Boot版本从1.3.2（1.9.2 spring-data-jpa）升级到当前的1.5.1（spring-data-jpa 1.11.0）我在启动时遇到异常。 提供更多内存，堆大小等没有帮助。 我认为问题在某种程度上与1.10.X之后的spring-data-jpa有关，因为我们在spring-data-jpa 1.9.x中没有这样的问题

Answer 1

GC overhead limit exceeded意味着您的应用程序有很多对象，并且GC大部分时间都在收集这些对象。 解决这个问题的常用方法是使用Eclipse MAT等工具进行堆转储并分析这些堆转储。

从日志中可以看出，应用程序在向HashMap赋值时耗尽了内存。

您提到您的应用程序中有很多实体。 这是否意味着您正在尝试立即从数据库加载数据？ 在这种情况下，为什么不修改您的应用程序以支持分页。 这样，您不会在应用程序中加载大量数据，并可能避免此错误。

Answer 2

如果你试图永远递归地解决问题（这听起来像你在做），你最终会得到一个堆栈溢出。 尝试将递归代码更改为迭代。

Answer 3

请注意，错误“超出GC开销限制”也可能由低xmx内存值引起。 我在64米上运行它并且它运行了一段时间，直到我添加了一些额外的jpa实体，这可能确实把它放在边缘。

我怀疑jpa的启动过程非常耗费内存。 花一些时间寻找递归问题导致cpu使用率几分钟非常高，有时错误永远不会出现，它只会卡住。
