推荐答案

servlet 容器是一个应用服务器，它实现了 Java Servlet 规范.

A servlet container is an application server that implements some version of the Java Servlet Specification.

简而言之，servlet 规范定义了一种编程模型，允许开发人员编写处理请求(几乎总是 HTTP 请求)的组件，例如 servlet.然后可以将这些组件声明到容器中，它会处理与连接和管理这些组件相关的许多繁琐任务，以便它们可以处理这些请求.

In a nutshell, the servlet spec defines a programming model that allows a developer to write components, for example servlets, that process requests (almost always HTTP requests). Those components can then be declared to the container and it handles many of the tedious tasks involved with wiring up and managing those components such that they can process those requests.
