Java虚拟机和 .NET 虚拟机:首先是Java虚拟机和.NET虚拟机。这两个系统都提供了JIT编译器、运行时支持和定义优良的字节码格式。这意味着任何可以编译成字节码格式的语言(有几十种格式)都可以利用优化器、JIT、运行时(runtime)。权衡的结果是,Java和.NET在实现运行时(runtime)的时候,几乎没有提供灵活性:它们都强...
Spring Framework itself is very powerful tool. It can do a lot of things for you and if it can’t – it plays nice with most of other frameworks in Java world. It suffers one thing – it is difficult to start coding in Spring and it’s often blamed for complexity. Indeed – boostra...
