servlet 3.1 在 JavaEE 7 下吗?
JavaEE 7 引入了 Servlet 3.1。
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 的这篇博文:Servlet 3.1 有哪些新变化?- Java EE 7 向前发展
而且我也想知道eclipse哪个版本支持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
除了 Eng.Fouad 给出的答案:Servlet 3.1 确实是随 Java EE 7 引入的,但它也由本身不是 Java EE 产品的各种服务器独立实现,例如Tomcat 8或Jetty 9.1。
至于变化,我在我的 ZEEF 页面上收集了一些专门关于 Servlet 3.1 中的新事物的数字或文章。
作为一个简短的总结;非阻塞 IO 和一些安全功能(如“*”角色)以及拒绝安全约束未明确涵盖的 HTTP 方法的可能性是一些主要变化。
