闭包的基本概念闭包是可以包含自由（未绑定）变量的代码块；这些变量不是在这个代码块或者任何全局上下文中定义的，而是在定义代码块的环境中定义。“闭包” 一词来源于以下两者的结合：要执行的代码块（由于自由变量的存在，相关变量引用没有释放）和为自由变量提供绑定的计算环境（作用域）。在 Scheme、Common Lisp、Smalltalk、Groovy、JavaScript、Ruby 和 Python 等语言中都能找到对闭包不同程度的支持。闭包的价值闭包的价值在于可以作为函数对象 或者匿名函数，对于类型系统而言这就意味着不仅要表示数据还要表示代码。支持闭包的多数语言都将函数作为第一级对象，就是说这些 Read More

Module SummaryLet's now examine the functionality that Spring offers in more detail. It is divided into a number of separate modules.There are two main categories of functionality in Spring:An IoC container and AOP framework, which handle configuration and application of services to objects.A se Read More
