Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。 Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。 Java 内存模型 Java 程序内存运行分析 Java 内存管理建议 JVM 内存溢出和参数调优  当遇到 OutOfMemoryError 时该如何做？ ▶ 常见的 OOM（Out Of Memory）内存溢出异常，就是堆内 存空间不足以存放新对象实例时导致。 ▶ 永久区内存溢出相对少见，一般是由于需要加载海量的 Class 数据，超过了非堆内存的容量导致。 ▶ 栈内存也会溢出，但是更加少见。
