开源Java Servlet 容器,Jetty 9.1.1 发布,

jopen 8年前

Jetty 是一个用 Java 实现、开源、基于标准的,并且具有丰富功能的 Web 服务器和 javax.servlet 容器,支持:SPDYWebSocketOSGiJMX,JNDIJAAS。Jetty 这个项目成立于 1995 年,现在已经有非常多的成功产品基于 Jetty,比如 Apache Geromino, JBoss, IBM Tivoli, Cisco SESM 等。Jetty 可以用来作为一个传统的 Web 服务器,也可以作为一个动态的内容服务器,并且 Jetty 可以非常容易的嵌入到 Java 应用程序当中。

特性

易用性

易用性是 Jetty 设计的基本原则,易用性主要体现在以下几个方面:

  1. 通过 XML 或者 API 来对 Jetty 进行配置;
  2. 默认配置可以满足大部分的需求;
  3. 将 Jetty 嵌入到应用程序当中只需要非常少的代码;

可扩展性

在使用了 Ajax 的 Web 2.0 的应用程序中,每个连接需要保持更长的时间,这样线程和内存的消耗量会急剧的增加。这就使得我们担心整个程序会因为单个组件陷入瓶颈而影响整个程序的性能。但是有了 Jetty:

  1. 即使在有大量服务请求的情况下,系统的性能也能保持在一个可以接受的状态。
  2. 利用 Continuation 机制来处理大量的用户请求以及时间比较长的连接。

另外 Jetty 设计了非常良好的接口,因此在 Jetty 的某种实现无法满足用户的需要时,用户可以非常方便地对 Jetty 的某些实现进行修改,使得 Jetty 适用于特殊的应用程序的需求。

易嵌入性

Jetty 设计之初就是作为一个优秀的组件来设计的,这也就意味着 Jetty 可以非常容易的嵌入到应用程序当中而不需要程序为了使用 Jetty 做修改。从某种程度上,你也可以把 Jetty 理解为一个嵌入式的Web服务器。

我们很高兴地宣布码头9.1.1的可用性!    已经解决了超过90个问题,鼓励大家尽快更新。解决的问题列在下面。      发布下载:    - http://download.eclipse.org/jetty/ The artifacts are also available in Maven Central.
