环境详细信息是。
Intellij IDE
Spring 4
Hibernate with simple schema of 30 tables
Elastic search client
Mysql
CRUD operation repository classes
所以我的问题是在应用程序自身启动时内存达到 950MB，这对我来说看起来不正常。
我正在使用基于注释的配置。
@Configuration
@Import({ElasticSearchConfig.class})
@PropertySources({
@PropertySource("classpath:application.properties"),
@PropertySource("classpath:sms_templates.xml")
})
@ComponentScan(basePackages = {"com.company"}, excludeFilters = {
@ComponentScan.Filter(value = {Controller.class, ControllerAdvice.class, RestController.class}, type = FilterType.ANNOTATION),
@ComponentScan.Filter(pattern = {"com\\.company\\.web\\..*"}, type = FilterType.REGEX)
})
@EnableAspectJAutoProxy
@EnableCaching
@EnableAsync

任何人都可以让我知道这里的问题，为什么它会出现如此高的堆使用率。除了轻量级属性文件之外，我没有加载任何数据。

最佳答案
尝试附加 jvisualvm 和 Goto Profiler --> Memory 选项卡或 Sample --> Memory。您可能会看到一些不应该出现在如此高数量的物体。或者进行内存转储并使用堆转储分析器。这将使您更清楚地了解正在发生的事情
关于java - spring 4 mvc + Hibernate + Annotations 配置堆内存问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42150539/
