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。

generally desirable. The main usage scenario when you might prefer to use the BeanFactory is when memory usage is the greatest concern (such as in an applet where every last kilobyte counts), and you don't ApplicationContext by default pre-instantiates singleton beans. At the cost of some upfront time and memory to create these beans before they are actually needed, you find out about configuration issues when used over the BeanFactory, except for a few limited situations such as perhaps in an Applet, where memory consumption might be critical, and a few extra kilobytes might make a difference. The following sections
