Using Ant and Yui compression JS implementation method _java

Because the project uses a lot of JS, in order to improve system efficiency, JS do compression processing.
Successful compression of more than one JS, you must go through the following two steps.
1. Merge multiple JS to become a JS.
2. Will and and after the JS compression processing.
The main ant configurations used are:

Copy Code code as follows:

<property name= "root" value= "WebRoot" ></property>
<property name= "JS" value= "${root}/js" ></property>
<property name= "Map_function_js" value= "${js}/mapfunc" ></property>
<property name= "Lib" value= "Lib"/>
<property name= ' build ' value= ' Build ' ></property>
<property name= "war" value= "war" ></property>
<property name= "War.info" value= "${war}/web-inf" ></property>
<property name= "War.lib" value= "${war.info}/lib" ></property>
<property name= "war.classes" value= "${war.info}/classes" ></property>
<property name= "Project.name" value= "Zjmap" ></property>
<property name= "CharSet" value= "Utf-8"/>
<property name= "src" value= "src"/>
<target name= "Create build Directory" >
<mkdir dir= "${build}"/>
</target>

Copy Code code as follows:
