java - Spring 数据 JPA OutOfMemoryError : GC overhead limit exceeded

Question

我正在开发一个包含大量实体 (3072) 的应用程序。我们使用 jhipster 作为项目结构。到目前为止一切正常，直到我们想将 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，而 GC 大部分时间都在收集这些对象。解决此问题的通常方法是获取堆转储并使用 Eclipse MAT 等工具分析这些堆转储。

从日志来看，应用程序似乎在向 HashMap 赋值时内存不足。

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一次从数据库加载数据？在那种情况下，为什么不修改您的应用程序以支持分页。这样，您就不会在应用程序中加载大量数据并可能避免此错误。
