之前发过一个

JFinal 自动探测Model 注册插件 AutoScanPlugin

http://my.oschina.net/b1412/blog/67764

然后参考了 对我的代码做出的扩展

jfinal的Model自动绑定表插件

http://www.oschina.net/code/snippet_591384_12022

现在整合下代码采用@Flio的插件命名，并且重构了一下搜索类的代码。

类探测api如下方便以后其类探测的使用.

List
    
      classList = ClassSearcher.findClasses(Model.class);
    

 插件注册代码,由于AutoTableBindPlugin继承自ActiveRecordPlugin,所以不需要单独注册它了.

主要数据库连接池插件要在AutoTableBindPlugin之前注册.

public void configPlugin(Plugins me) {		DruidPlugin druidPlugin = new DruidPlugin.DruidBuilder(				getProperty("url"), getProperty("username"),				getProperty("password")).build();		AutoTableBindPlugin autoTableBindPlugin = new AutoTableBindPlugin(				druidPlugin, TableNameStyle.LOWER);		autoTableBindPlugin.setShowSql(true);		SqlReporter.setLogger(true);		SqlInXmlPlugin sqlInXmlPlugin = new SqlInXmlPlugin();		QuartzPlugin quartzPlugin = new QuartzPlugin();		me.add(druidPlugin).add(sqlInXmlPlugin).add(autoTableBindPlugin).add(quartzPlugin);            	}

目前之内探测/classes下的类，如果是/lib下jar包中的类还不能探测。

之前做过运行动态修改字节码的工具，是吧lib下的jar解压出来然后修改了打包回去。如果需要探测jar中类是否为Model子类是否必须坐jar包解压的工作？大家有什么好的方案么？这个问题弄清楚了再加上扫描jar包中Model的工作。

目前如果是有项目吧class文件打成jar包部署的朋友暂时无法使用自动探测绑定的功能...
