ant 的常用语法和功能

1. <property file="build.properties"/>

 

把build.properties文件里的键值对导入到build.xml ，以后就可以在build.xml 里使用${db.driver}来读到build.properties里配置的值org.hsqldb.jdbcDriver
这个很有用，需要改变值的时候，只需改变build.properties的值，但build.xml文件不用修改

db.url=jdbc:hsqldb:hsql://localhost/training
db.driver=org.hsqldb.jdbcDriver
db.username=sa
db.password=
hibernate.dialect=net.sf.hibernate.dialect.HSQLDialect

 2.<path id="ant.lib.path"></path>

指定了一个路径，路径下放着指定的jar文件

3. <path location="${classes.dir}"/>

指定了一个路径里的所有文件

4. <fileset dir="${xdoclet.lib.dir}">
      <include name="*.jar"/>
    </fileset>

这个表示把路径${xdoclet.lib.dir}里的所有的.jar文件包括进来，不包括子文件夹里的.jar文件

如果用这个 <include name="**/*.jar"/>，表示包括这个文件夹里所有的 .jar文件，包括所有子文件夹里的.jar文件

5.<copy toDir="${depends.dir}">
      <mapper type="flatten"/>
      <fileset refid="runtime.fileset"/>
    </copy>

表示将id名为runtime.fileset的<fileset >里包括的文件去掉文件夹copy到${depends.dir}

6. 打包工程

 <war destfile="${war.file}" webxml="${webxml.file}">
      <lib dir="${lib.dir}" includes="*.jar"/>
      <lib dir="${depends.dir}" includes="*.jar"/>
     
      <classes dir="${classes.dir}"/>
      <classes dir="${hbm.dir}"/>
      <webinf dir="${webinf.dir}" excludes="web.xml"/>
      <webinf dir="${target.dir}/webapp/WEB-INF"/>
      <fileset dir="${web.src.dir}" includes="index.html,jsp/**"/>
    </war>

destfile 在指定位置创造了一个.war文件

webxml 将指定位置的web.xml 放在webapp/WEB-INF里

<lib  将所包含的jar文件放在WEB-INF/lib 里

<classes 将所包含的文件放在WEB-INF/classes 里

<webinf   将指定路径的所有文件，除了web.xml，全部都copy到WEB-INF/里

<fileset  将指定路径的所有文件全部都copy到WEB-INF/的父目录，则和WEB-INF在同一个目录

7.用于将build.properties文件里的值来修改hibernate.properties里的属性值，动态生成一个hibernate.properties文件

<filter token="db.url" value="${db.url}"/>

<copy todir="${target.dir}/webapp/WEB-INF"
        file="${config.dir}/hibernate.properties"
        filtering="true"
        overwrite="true"/>

 

表示但把  file指定路径下的hibernate.properties文件copy到指定路径时，将会执行一个动作，在hibernate.properties文件里所有出现的这个字符串（token指定的字符串）将被value指定的值所替换
