6、如果实现了BeanPostProcessor接口,将调用postProcessBeforeInitialization方法(在对象实例化前进行操作) 7、如果实现了InitializingBean接口,或者在bean中声明了init-method则调用他们的初始化方法对bean进行初始化(如果两个都指定,则先执行接口中指定的方法,再执行配置中指定的初始化方法) 8、如果实现了BeanPostProcesso...
it will be different in most cases, because it uses a singleSystem.currentTimeMillis()and twoSystem.nanoTimecalls for seed initialization). As a result, iteration order

String类是Java中非常特别的一个类,虽然不是基本数据类型,但是通过一些处理,又在引用数据类型里比较特别,在学习之前,先了解一些JVM的知识。 Method Area:方法区,当虚拟机装载一个class文件时,它会从这个class文件包含的二进制数据中解析类型信息,然后把这些类型信息(包括类信息、常量、静态变量等)放到方法区中,该内存...
