proxool配置文件中用户和密码加密

Javaproxool加密配置连接池 
阅读更多

proxool是个很好的开源连接池。但配置文件中的用户和密码却是明文存储的，如果对系统安全有较高的要求，使用时就麻烦了。昨天下了Proxool 0.9.1的源码，研究了下，做了些小小的改动，现在proxool配置文件中用户和密码可以使用密文存储了，同时明文的也可以正常使用。解密功能部分做成了接口，可以用自己的算法来实现，很方便。

 

先上配置文件proxool.xml

<?xml version="1.0" encoding="gb2312"?>     

<!-- the proxool configuration can be embedded within your own application's. Anything outside the "proxool" tag is ignored. -->     

<something-else-entirely>   
    <proxool>   
        <!--连接池的别名-->   
        <alias>hdqt</alias>
		<!--实现解密的工具类-->  
        <encrypt>cn.bq.tools.DecUtil</encrypt>
        <!--proxool只能管理由自己产生的连接-->   
        <driver-url>jdbc:microsoft:sqlserver://127.0.0.1:1433;databaseName=xxxx</driver-url>   
        <!--JDBC驱动程序-->   
        <driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>   
        <driver-properties>   
			<!--加密后的用户名和密码-->
            <property name="user" value="da33e8657877280c32683ae317ef78e1"/>   
            <property name="password" value="3defde98af47835a74537600eebe78f2"/>   
        </driver-properties>   
        <!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁-->   
        <house-keeping-sleep-time>90000</house-keeping-sleep-time> 
        <house-keeping-test-sql>select getdate()</house-keeping-test-sql>
        <!-- 指因未有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受-->     
        <!--maximum-new-connections>150</maximum-new-connections-->   
	<simultaneous-build-throttle>5</simultaneous-build-throttle>
        <!-- 最少保持的空闲连接数-->     
        <prototype-count>3</prototype-count>   
        <!-- 允许最大连接数,超过了这个连接，再有请求时，就排在队列中等候，最大的等待请求数由maximum-new-connections决定-->     
        <maximum-connection-count>100</maximum-connection-count>   
        <!-- 最小连接数-->   
        <minimum-connection-count>3</minimum-connection-count>   
    </proxool>

 Revision history:
 $Log: ProxoolConstants.java,v $
 Revision 1.21  2004/06/02 20:39:17  billhorsman
 New injectable interface constants

 Revision 1.20  2004/03/15 02:43:47  chr32
 Removed explicit JNDI properties. Going for a generic approach instead.
 Added constant for JNDI properties prefix.

 Revision 1.19  2003/09/30 18:39:08  billhorsman
 New test-before-use, test-after-use and fatal-sql-exception-wrapper-class properties.

 Revision 1.18  2003/09/29 17:48:21  billhorsman
 New fatal-sql-exception-wrapper-class allows you to define what exception is used as a wrapper. This means that you
 can make it a RuntimeException if you need to.

 Revision 1.17  2003/09/05 17:00:42  billhorsman
 New wrap-fatal-sql-exceptions property.

 Revision 1.16  2003/07/23 06:54:48  billhorsman
 draft JNDI changes (shouldn't effect normal operation)

 Revision 1.15  2003/03/05 23:28:56  billhorsman
 deprecated maximum-new-connections property in favour of
 more descriptive simultaneous-build-throttle

 Revision 1.14  2003/03/03 11:11:58  billhorsman
 fixed licence

 Revision 1.13  2003/02/26 16:05:52  billhorsman
 widespread changes caused by refactoring the way we
 update and redefine pool definitions.

 Revision 1.12  2003/02/24 18:02:24  chr32
 Added JMX related constants.

 Revision 1.11  2003/02/24 01:16:15  chr32
 Added constant for "driver-properties" property.

 Revision 1.10  2003/02/06 15:41:17  billhorsman
 add statistics-log-level

 Revision 1.9  2003/01/30 17:22:03  billhorsman
 new statistics property

 Revision 1.8  2003/01/23 10:41:05  billhorsman
 changed use of pool-name to alias for consistency

 Revision 1.7  2002/12/26 11:32:22  billhorsman
 Moved ALIAS, DRIVER_URL and DRIVER_CLASS constants
 from XMLConfgiurator to ProxoolConstants.

 Revision 1.6  2002/12/15 19:22:51  chr32
 Added constant for proxool xml namespace.

 Revision 1.5  2002/12/11 01:47:12  billhorsman
 extracted property names without proxool. prefix for use
 by XMLConfigurators.

 Revision 1.4  2002/11/09 15:50:49  billhorsman
 new trace constant

 Revision 1.3  2002/10/27 13:29:38  billhorsman
 deprecated debug-level in favour of verbose

 Revision 1.2  2002/10/25 15:59:32  billhorsman
 made non-public where possible

 Revision 1.1.1.1  2002/09/13 08:13:06  billhorsman

 Revision 1.6  2002/07/02 11:19:08  billhorsman
 layout code and imports

 Revision 1.5  2002/07/02 08:27:47  billhorsman
 bug fix when settiong definition, displayStatistics now available to ProxoolFacade, prototyper no longer attempts to make connections when maximum is reached

 Revision 1.4  2002/06/28 11:19:47  billhorsman

 * <p>This is just a <a

 * target="_new" >ContentHandler</a>, so you must associate it with a SAX parser
 * for it to actually do anything. If you have JAXP available {@link JAXPConfigurator}
 * will do this for you.</p>
 *
 * <p>Properties that you pass on to the delegate driver have to be treated

 * <p>See the <a href="The latest version is available at

 * automatically registered. You can contain the &lt;proxool&gt; element in any
 * other elements as you wish. And the &lt;proxool&gt; element can occur as many
 * times as you wish. This allows you to use an XML file that configures your
 * whole application as the source. This configurator will ignore everything
 * apart from the elements contained within the &lt;proxool&gt; element. <p><a
 * name="#validation"> <b>Validation</b><br> A couple of additional steps are
 * required if you want your SAX parser to validate your Proxool xml
 * confguration: <ul> <li> Put your proxool configuration elements inside a root
 * <code>proxool-config</code> element. The document must adhere to the <a
 * href="proxool.dtd">Proxool dtd</a>. </li> <li> Add a
 * <code>DOCTYPE</code> entry to your xml with a system id containing the
 * <i>absolute url</i> to the Proxool dtd. The Proxool jar contains a copy of
 * the Proxool dtd in the confguration package. You can reference that with a
 * jar url like this:<br>
 * <code><nobr>&lt;!DOCTYPE proxool-config SYSTEM "jar:file:///C:/Proxool/lib/proxool.jar!/org/logicalcobwebs/proxool/configuration/proxool.dtd"&gt;</nobr></code></li>
 * <li> Configure your parser to be validating. In the {@link JAXPConfigurator}
 * this is done by passing
 * <code>true</code> as the second arghument to any of the
 * <code>configure</code> methods. </li> </ul> </p> <p>This class is not thread

把上面这几个类编译后，添加、替换原包中的类就可以了。使用上跟原来没有区别。

注意：如果配置使用了解密，就必须先实现接口Decryptool，并在配置文件中设置正确的类路径

接口Decryptool的简单实现：

        String s = null;
        try {
            byte[] b = decode.decodeBuffer(string);
            s = new String(b);
        } catch (IOException ex) {
            Logger.getLogger(DecUtil.class.getName()).log(Level.SEVERE, null, ex);
