我們通過 Hello World Fax Web 應(yīng)用,已經(jīng)瑣碎地學(xué)習(xí)了 Ant 的不同方面的知識了。
現(xiàn)在是時(shí)候把我們所學(xué)的知識都運(yùn)用起來創(chuàng)建一個(gè)全面和完整的 build.xml 文件了。考慮下面給出的 build.properties 和 build.xml 文件:
eploy.path = c:\tomcat6\webapps
<?xml version = "1.0"?>
<project name = "fax" basedir = "." default = "usage">
<property file = "build.properties"/>
<property name = "src.dir" value = "src"/>
<property name = "web.dir" value = "war"/>
<property name = "javadoc.dir" value = "doc"/>
<property name = "build.dir" value = "${web.dir}/WEB-INF/classes"/>
<property name = "name" value = "fax"/>
<path id = "master-classpath">
<fileset dir = "${web.dir}/WEB-INF/lib">
<include name = "*.jar"/>
</fileset>
<pathelement path = "${build.dir}"/>
</path>
<target name = "javadoc">
<javadoc packagenames = "faxapp.*" sourcepath = "${src.dir}"
destdir = "doc" version = "true" windowtitle = "Fax Application">
<doctitle><![CDATA[<h1> = Fax Application = </h1>]]>
</doctitle>
<bottom><![CDATA[Copyright ? 2011. All Rights Reserved.]]>
</bottom>
<group title = "util packages" packages = "faxapp.util.*"/>
<group title = "web packages" packages = "faxapp.web.*"/>
<group title = "data packages" packages = "faxapp.entity.*:faxapp.dao.*"/>
</javadoc>
</target>
<target name = "usage">
<echo message = ""/>
<echo message = "${name} build file"/>
<echo message = "-----------------------------------"/>
<echo message = ""/>
<echo message = "Available targets are:"/>
<echo message = ""/>
<echo message = "deploy --> Deploy application as directory"/>
<echo message = "deploywar --> Deploy application as a WAR file"/>
<echo message = ""/>
</target>
<target name = "build" description = "Compile main source tree java files">
<mkdir dir = "${build.dir}"/>
<javac destdir = "${build.dir}" source = "1.5" target = "1.5" debug = "true"
deprecation = "false" optimize = "false" failonerror = "true">
<src path = "${src.dir}"/>
<classpath refid = "master-classpath"/>
</javac>
</target>
<target name = "deploy" depends = "build" description = "Deploy application">
<copy todir = "${deploy.path}/${name}" preservelastmodified = "true">
<fileset dir = "${web.dir}">
<include name = "**/*.*"/>
</fileset>
</copy>
</target>
<target name = "deploywar" depends = "build" description = "Deploy application as a WAR file">
<war destfile = "${name}.war" webxml = "${web.dir}/WEB-INF/web.xml">
<fileset dir = "${web.dir}">
<include name = "**/*.*"/>
</fileset>
</war>
<copy todir = "${deploy.path}" preservelastmodified = "true">
<fileset dir = ".">
<include name = "*.war"/>
</fileset>
</copy>
</target>
<target name = "clean" description = "Clean output directories">
<delete>
<fileset dir = "${build.dir}">
<include name = "**/*.class"/>
</fileset>
</delete>
</target>
</project>
在上面給出的例子中:
上述的例子向我們展示了兩個(gè)部署目標(biāo): deploy 和 deploywar 。
這個(gè) deploy 目標(biāo)將文件從 web 目錄復(fù)制到部署目錄,并保存最后修改日期時(shí)間戳。這樣很有用,特別是當(dāng)我們將項(xiàng)目部署到服務(wù)器上,并且該服務(wù)器支持熱部署。(釋義:所謂熱部署,就是在應(yīng)用正在運(yùn)行的時(shí)候升級軟件,卻不需要重新啟動(dòng)應(yīng)用。)
這個(gè) clean 目標(biāo)清楚所有之前的構(gòu)建文件。
這個(gè) deploywar 目標(biāo)構(gòu)建 war 文件,然后將 war 文件復(fù)制到應(yīng)用程序服務(wù)器的部署目錄。
