用ant+tomcat编译打包jsp文件

我们在tomcat下打包发布web程序程序时,需要把jsp文件先编译成class文件，这样有利于保护源代码，也可以提高访问速度。
首先我们编写build.properties，设置一些基本路径：

tomcat.home = D: / Tomcat  5.0
java.home = D: / jdk1. 4
#工程目录
project.home = D: / projects / preference / trunk / code
#web模块目录
webapp.path = D: / projects / preference / trunk / code / webapp
#code目录
src = D: / projects / preference / trunk / code / javacode

 

编写好build.properties后，我们编写build.xml.

 

<? xml version = " 1.0 "  encoding = " GB2312 " ?>
< project name = " Webapp Precompilation "   default = " all "  basedir = " . " >  
< property file = " build.properties " />
<!--  设定工程编译临时存放class路径  -->
< property name = " dest "  value = " build/classes.ant " />
<!--  设定工程发布后的路径  -->

<!--  设定工程依赖的jar包  -->

然后把build.properties和build.xml拷贝到工程目录下，在工程目录下执行ant,编译完成后，
如果成功可以看到产生一个build文件夹，里面有classes.ant，src,WebRoot,WEB-INF四个文件夹，
另外还有code.jar,jsp.jar,和generated_web.xml三个文件。classes.ant，src,WEB-INF是临时文件，
已经没用，code.jar是java代码打成的jar包，jsp.jar是jsp打成的jar包。只须把code.jar,jsp.jar拷到WebRoot/WEB-INF/lib下，然后把generated_web.xml的内容加到
WebRoot/WEB-INF/web.xml里。现在你就可以拿WebRoot去发布了，里面没有任何源程序代码。
