macrodef 直接解释是宏, 理解上可以是自定义标签或者自定义函数
对于大型部署提高代码利用率
为了方便理解通过以下代码:
<macrodef name="macro-send-file"> <attribute name="host" /> <attribute name="toPath" /> <attribute name="file" /> <attribute name="userID" /> <attribute name="password" /> <sequential> <echo>@{userID}:@{password}@@@{host}:@{toPath}</echo> <scp verbose="false" trust="true" localFile="@{file}" todir="@{userID}:@{password}@@@{host}:@{toPath}" failonerror="true" /> <!-- sshexec trust="true" host="@{host}" username="@{userID}" password="@{password}" command="chmod -R u+rw,g+rwx @{toPath}/*.ear"/ --><sshexec trust="true" host="@{host}" username="@{userID}" password="@{password}" command="chown thangamm:wadmfsms @{toPath}/*.ear"/> <echo>Sent @{file} to @{host}:@{toPath}</echo> <!-- delete build dir --> <echo message="clean app project" /> <!-- after done, should clean the preparation folders but keep release folder --> <delete dir="${build.dir.app}${file.separator}${name.bin}" failonerror="false" /> <delete dir="${build.dir.app}${file.separator}${name.docs}" failonerror="false" /> <delete dir="${build.dir.app}${file.separator}${name.reports}" failonerror="false" /> <delete dir="${build.dir.app}${file.separator}${name.stage}" failonerror="false" /> <echo message="clean core project" /> <delete dir="${build.dir.core}" failonerror="false" /> <echo message="clean web project" /> <delete dir="${build.dir.web}" failonerror="false" /> </sequential> </macrodef>
<macrodef name="macro-send-file"> name 属性说明这个自定义宏的名字 通过这个name 来调用
如下调用这个宏
<macro-send-file file="${file}" host="${autodeploy.host}" topath="${autodeploy.path}/${envName}" userid="${autodeploy.userID}" password="${autodeploy.password}" />
<attribute name="host" /> 表示宏的输入参数(相当于函数的参数)。在marcodef 中不同通过${}来调用attrbute 的值而要通过@{}。例如显示传入参数userID 是什么通过<echo>@{userID}.
<sequential> 相当于函数的body 就是你这个可以调用常用ant tag 如何copy javac mkdir jar war 等
