首先每个中间件对应的ModuleClassLoader在加载中间对应的class文件的同时,根据中间件配置的export.index负责将要需要透出的class(主要是提供api接口的相关类)索引到exportedClassHashMap中,然后应用程序的类加载器会持有这个exportedClassHashMap,因此应用程序代码在loadClass的时候,会优先判断exportedClassHashMap是否存在当前类...

在上面的示例程序中,尽管外部类 OutsideClass 的属性是用 private 修饰的,内部类 InsideClass 依然可以对这些属性进行无缝访问。此时教学重点在于从两个角度给学生讲解内部类对外部类的访问:一个角度是把内部类看成外部类的一个成员,外部内的一个成员当然可...
这个选项对性能影响比较大,需要严格的测试。(校长) 和threadstacksize选项解释很类似,官方文档似乎没有解释,在论坛中有这样一句话:"”-Xss is translated in a VM flag named ThreadStackSize” 一般设置这个值就可以了。 动态生成类的情况比较容易出现永久代的内存溢出。最典型的场景就是,在 jsp 页面比较多的情况,...
Class文件的内容是什么? Java class文件中包含了Java虚拟机所需知道的,关于类或接口的所有信息。 A class file consists of a single ClassFile structure: ClassFile { u4 magic; u2 minor_version; u2 major_version; u2 constant_pool_count; cp_info constant_pool[constant_pool_count-1]; ...

简单的说,内部(inner)类指那些类定义代码被置于其它类定义中的类;而对于一般的、类定义代码不嵌套在其它类定义中的类,称为顶层(top-level)类。对于一个内部类,包含其定义代码的类称为它的外部(outer)类。1 Static member class(静态成员类)类声明中包含“static
