tomcat8.032位/64位官方版是Apache 軟件基金會(huì)(Apache Software Foundation)的Jakarta 項(xiàng)目中的一個(gè)核心項(xiàng)目,由Apache、Sun 和其他一些公司及個(gè)人共同開發(fā)而成。由于有了Sun 的參與和支持,最新的Servlet 和JSP 規(guī)范總是能在Tomcat 中得到體現(xiàn),Tomcat 7 支持最新的Servlet和JSP規(guī)范。因?yàn)門omcat 技術(shù)先進(jìn)、性能穩(wěn)定,而且免費(fèi),因而深受Java 愛好者的喜愛并得到了部分軟件開發(fā)商的認(rèn)可,成為目前比較流行的Web 應(yīng)用服務(wù)器,主要適用于任何32位和64位系統(tǒng)。
Apache Tomcat發(fā)布8.0.9版本,同時(shí)這個(gè)版本也是8.0的第一個(gè)stable版本。Tomcat 8需要至少JDK7以上。
值得注意的更新如下:
Support for Java Servlet 3.1, JavaServer Pages 2.3, Java Unified Expression Language 3.0 and Java WebSocket 1.0.
The default connector implementation is now the Java non-blocking implementation (NIO) for both HTTP and AJP.
A new resources implementation that replaces Aliases, VirtualLoader, VirtualDirContext, JAR resources and external repositories with a single, consistent approach for configuring additional web application resources. The new resources implementation can also be used to implement overlays (using a master WAR as the basis for multiple web applications that each have their own customizations).
Apache Tomcat 8.0.9 包括了 8.0.8 版本的 bug 修復(fù)和大量改進(jìn),相對(duì)于 8.0.8 版本:
Start to move towards RFC6265 for cookie handling
Better error handling when the error occurs after the response has been committed
Various Jasper improvements to make it easier for other containers (e.g. Jetty) to consume
