This article uses a simple Web project as an example to describe how to package a Web foreground program using ANT.Contains three parts: file copy, compile, and package; complete these three parts and you get a War that runs under Tomcat.
Installation of ANT, setting of environment variables, etc. are omitted.There are many articles on the Internet.
Dead workFirst, create a simple Web program that displays "Hello ANT!!!" through a simple Web page (index.html).Programs rely on third-party Jar packages GSON.The basic program structure is as follows:
The ant script build.xml is placed in the tools/build directory, and the war packages generated by packaging and compiling are placed under runtime.
Write build.xml file<?xml version="1.0" encoding="utf-8" ?> <project name="WebAntTest" default="create_war" basedir="../../"> <!--Define the current time--> <tstamp> <format property="current_date" pattern="yyyy_MM_dd_HH_mm_ss" locale="en"></format> </tstamp> <!--Define Dependencies jar Path to package--> <path id="depend_lib_path"> <fileset dir="WebContent\WEB-INF\lib"> <include name="*.jar"></include> </fileset> </path> <!--Delete old packaged files(contain war Packaging and Compiling Files)--> <target name="clean"> <delete verbose="true" includeemptydirs="true"> <fileset dir="build"> <include name="**/*"/> </fileset> </delete> <delete verbose="true" includeemptydirs="true"> <fileset dir="runtime"> <include name="**/*"/> </fileset> </delete> </target> <!--Compile Generation class file--> <target name="compile" depends="clean"> <javac srcdir="src" destdir="build" includeantruntime="on"> <classpath refid="depend_lib_path"></classpath> </javac> </target> <!--hit war package--> <target name="create_war" depends="compile"> <war destfile="runtime/AntWeb.war" webxml="WebContent/WEB-INF/web.xml"> <fileset dir="WebContent"> <exclude name="**.jar"/> <exclude name="**.class"/> </fileset> <lib dir="WebContent\WEB-INF\lib"></lib> <classes dir="build"/> </war> </target> </project>test run
Switch the current path to the tools/build directory, execute the ant command to complete the packaging operation, and generate a war package in the runtime directory:
Packaging process:
In order to package as a timed task, you can also add a batch build.bat:
::Start Packager cd /d %cd% start "Start Packager..." ant.Publish War Package
Put the packaged war file under tomcat's webApps and run Tomcat.Accessed through the web page, it can be displayed normally.
