哪个版本的eclipse支持servlet 3.1开发？
JavaEE 7下是servlet 3.1吗？
Servlet 3.1随JavaEE 7一起引入。
Servlet 3.1与Servlet 3.0有何不同？
关于Servlet 3.1的新变化，请阅读Arun Gupta撰写的这篇博文： Servlet 3.1中有哪些新变化？ – Java EE 7向前发展
而且我也想知道哪个版本的eclipse支持servlet 3.1开发。
新版本的Eclipse 4.3（名为Kepler）支持Java EE 7技术。 请参阅Arun Gupta的博客文章： Eclipse 4.3中的Java EE 7支持
Servlet 3.1与Servlet 3.0以及其他版本一样

除了Eng.Fouad给出的答案之外：Servlet 3.1确实是在Java EE 7中引入的，但它也是由各种服务器独立实现的，这些服务器本身不是Java EE产品，例如Tomcat 8或Jetty 9.1 。
至于更改，我在ZEEF页面上收集了一些或多篇文章 ，这些文章专门介绍Servlet 3.1中的新内容。
作为简短摘要; 非阻塞IO和一些安全function，如’*’角色和拒绝安全约束未明确涵盖的HTTP方法的可能性是一些重大变化。
