java源码：多播事件总线 Avis.zip

Avis ====================================================================== This package contains the Avis publish/subscribe message router. For more information on the Avis project please see: http://avis.sourceforge.net/ Installation ---------------------------------------------------------------------- Simply unzip the distribution. Supported Platforms ---------------------------------------------------------------------- Avis will run on platforms with a Java 5 Standard Edition runtime. It has been tested on Mac OS X (10.4 and 10.5), Windows XP and Windows Server 2003, Fedora (Core 2 through 8) and Debian Sarge (3.1). Although Avis is platform-independent, the "avisd" script and example command lines appearing later are for Unix environments with a Bourne shell. Windows users can either translate as needed or run under cygwin (http://www.cygwin.com). Requirements ---------------------------------------------------------------------- Avis requires a Java 1.5 runtime: it will run fine with a minimal Java Runtime Environment (JRE) but it is recommended you install a full Java 5 or Java 6 (recommended) JDK to gain access to the "server" optimizing VM which significantly improves the performance of Avis. There is no requirement to build from source since platform- independent binaries are included with the distribution, but if you do wish to compile Avis you will need a Java Development Kit. If you don't need to build Avis, you can skip to the next section. Unless you plan to build Avis from Eclipse, you will also need Apache Ant 1.6.0 or later (http://ant.apache.org). Optional: * Eclipse 3.2 or later. Project files for Eclipse are included with the distribution, import them using File -> Import -> Existing Projects Into Workspace. The version of Ant bundled with Eclipse is sufficient to build Avis. Eclipse is available from http://www.eclipse.org/downloads. * JavaCC 4.0 or later. Only required if you wish to change the subscription parser. http://javacc.dev.java.net. To build the router with Ant, change to the "server" sub-directory of where you extracted Avis and simply run Ant with the default build target: > cd avis-1.2/server > ant This will build the file "lib/avis-router.jar", which is the Avis event router executable. To see all build targets run: > ant -projecthelp Usage ---------------------------------------------------------------------- To run the Avis event router service using the bash helper script: > cd avis-1.2/server > ./bin/avisd To see command line options: > ./bin/avisd -h You can use the ec (Elvin Consumer) and ep (Elvin Producer) utilities which are bundled with the router to subscribe to and generate notifications from the command line. [from shell #1] > ec -e elvin://localhost "require (Hello-World)" ec: Connected to server elvin:4.0/tcp,none,xdr/localhost:2917 [from shell #2] > ep -e elvin://localhost Hello-World: 1 ^D ep: Closing connection [output on shell #1] $time 2007-04-13T20:37:28.156+0930 Hello-World: 1 --- You can also try one of the tickertape messaging clients at tickertape.org: http://tickertape.org/get_tickertape.html
