究竟什么是中间件? [英] What is middleware exactly?

问题描述

我最近听到很多人谈论中间件，但是中间件的确切定义是什么?当我研究中间件时，我发现了很多信息和一些定义，但是在阅读这些信息和定义时，似乎大多数商品"都在某个东西的中间.那么，所有东西都是中间件吗?

I have heard a lot of people talking recently about middleware, but what is the exact definition of middleware? When I look into middleware, I find a lot of information and some definitions, but while reading these information and definitions, it seems that mostly all 'wares' are in the middle of something. So, are all things middleware?

或者你有不是中间件的例子吗?

Or do you have an example of a ware that isn't middleware?

推荐答案

假设您的公司生产 4 种不同的产品，您的客户还有另外 3 种不同公司的另外 3 种不同产品.

Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.

有一天，客户想，我们为什么不将所有系统集成到一个庞大的系统中.十分钟后，他们的 IT 部门说这需要 2 年时间.

Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.

您(聪明的开发者)说，我们为什么不把所有不同的系统整合起来，让它们一起工作呢?客户经理盯着你……你继续说，我们将使用中间件，我们将研究所有不同系统的输入/输出，它们使用的资源，然后选择合适的中间件框架.

You (the wise developer) said, why don't we just integrate all the different systems and make them work together? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.

仍在向非技术经理解释
中间有中间件框架，第一个系统会产生 X 的东西，系统 Y 和 Z 会消耗这些输出等等.

Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.
