PROXOOL连接数据库,但是不用spring等，需要实现加密解密数据库密码，怎么做

Question

项目中又不使用Spring等，要实现用如下的配置也能连接数据库，请问除了直接修改类以外有无继承等修改方式，加载此文件的方式用的是  JAXPConfigurator.configure() 或者
--------------------------web.xml中配置
<servlet>   
      <servlet-name>proxoolInitialServlet</servlet-name>   
  <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>   
      <init-param>   
        <param-name>xmlFile</param-name>   
        <param-value>WEB-INF/proxool.xml</param-value>   
      </init-param>   
      <load-on-startup>1</load-on-startup>   
    </servlet>
---------------------------------------------------------------------------------xool.xml文件
 <proxool>
    <alias>BACKSTAGE_DB</alias>
    <driver-url>jdbc:sqlserver://127.0.0.1:1433;database=TEST_DB</driver-url>
    <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
    <driver-properties>
      <property name="user" value="sa"/>
      <property name="password" value="6D7F054306F096AA"/><!-- DES加密的字符串-->
    </driver-properties>
    <minimum-connection-count>1</minimum-connection-count>
    <maximum-connection-count>30</maximum-connection-count>
    <house-keeping-test-sql>select getdate()</house-keeping-test-sql>
    <house-keeping-sleep-time>600000</house-keeping-sleep-time>
    <statistics>10s,1m,1d</statistics>
  </proxool>
