/**
 * MixPrefix is a kind of id generation strategy. MixPrefix assembles prefix,
 * original string, paddingChar into new id. For example, <br>
 * prefix is a 'TEST-' <br>
 * paddingChar is a '0' <br>
 * original string is a '12' <br>
 * and maxCiphers is a 5 <br>
 * in result, new id is a 'TEST-00012'.
 * 
 * * The Configuration to use a MixPrefixStrategy looks like the following:
 * 
 * <pre>
 *  &lt;property name=&quot;prefix&quot; value=&quot;TEST-&quot;/&gt;   
 *  &lt;property name=&quot;maxCiphers&quot; value=&quot;5&quot;/&gt;
 *  &lt;property name=&quot;paddingChar&quot; value=&quot;0&quot;/&gt;
 * </pre>
