Jetty 9.3.15.v20161216 发布,一个servlet容器

 

Jetty 是一个开源的servlet容器,它为基于Java的web内容,例如JSP和servlet提供运行环境。Jetty是使用Java语言编写的,它的API以一组JAR包的形式发布。开发人员可以将Jetty容器实例化成一个对象,可以迅速为一些独立运行(stand-alone)的Java应用提供网络和web连接。

和Tomcat的比较:

  1. Jetty更轻量级。这是相对Tomcat而言的。
    由于Tomcat除了遵循Java Servlet规范之外,自身还扩展了大量JEE特性以满足企业级应用的需求,所以Tomcat是较重量级的,而且配置较Jetty亦复杂许多。但对于大量普通互联网应用而言,并不需要用到Tomcat其他高级特性,所以在这种情况下,使用Tomcat是很浪费资源的。这种劣势放在分布式环境下,更是明显。换成Jetty,每个应用服务器省下那几兆内存,对于大的分布式环境则是节省大量资源。而且,Jetty的轻量级也使其在处理高并发细粒度请求的场景下显得更快速高效。
  2. Jetty更灵活
    体现在其可插拔性和可扩展性,更易于开发者对Jetty本身进行二次开发,定制一个适合自身需求的Web Server。 相比之下,重量级的Tomcat原本便支持过多特性,要对其瘦身的成本远大于丰富Jetty的成本。用自己的理解,即增肥容易减肥难。
  3. 然而,当支持大规模企业级应用时,Jetty也许便需要扩展,在这场景下Tomcat便是更优的。
