使用 ant 让你愉快编程(5)

摘要: build_tomcat.xml, tomcat.xml

现在介绍一下如何与 tomcat 一起配合工作.
java 的程序很大部分都涉及 web, 自己测试时使用 tomcat 还是很方便的,
所以有必要介绍一下.

在 work/common/ 下的 build_tomcat.xml, tomcat.xml 这两个文件是与
tomcat 配合工作的配置文件, 它的内容很简单.

. 以下为 build_tomcat.xml 文件内容:

以下为 tomcat.xml 的内容.

<?xml version="1.0" encoding="ISO-8859-1"?> <!-- Copyright 2004 camry.wu@gmail.com Ant build environment for tomcat --> <root> <tomcat> <!-- 配置 tomcat.home 位置 --> <home value="/usr/tomcat.home"/> <!-- 配置 tomcat 的管理界面 --> <manager> <url>http://127.0.0.1:8080/manager</url> <username>camry</username> <password>xxxxx</password> </manager> </tomcat> <path> <!-- 配置发布的源 war 位置 --> <war>war</war> <!-- 发布到 tomcat 的 webapps 目录下 --> <deploy>${tomcat.home}/webapps</deploy> </path> </root>

在使用的时候, 要注意先在 work/工程目录/ 下建立 war 目录,
war 目录结构为:
  work/工程目录/war
      WEB-INF/
        classes/                  # 放置 class 文件
        lib/                      # 放置需要的 jar 包
        web.xml                   # web 配置文件

有了这些配置, 在与 tomcat 配合时只要启动 tomcat 先, 随后就不用
再管 tomcat 了, 只要调用 ant deploy, ant stop, ant start 等等
任务就可以了.
