呵呵，反正方法名称里面带Bean的就是针对条件在bean对象/List<bean>、SQLParams/List<SQLParams>和Map/List<Map>对象中的这种情况，并且sql语句是模板sql

不带Bean的就是预编译sql语句，变量以?号代替,参数就可以在后面追加

如果要指定dbname的话就在相应的方法后面添加WithDBName

分页方法时需要指定起始地址和每页记录数

还有指定行处理器和空行处理器、Field行处理器的一组接口，呵呵

没办法为了满足各种要求必须提供这么多接口，我估计bboss的persistent应该是业界接口最全的一套persistent framework了，呵呵

sql配置文件如下： 
<?xml version="1.0" encoding='gb2312'?>
<properties>
	<description>
<![CDATA[
	sql配置文件
	可以通过名称属性name配置默认sql，特定数据库的sql通过在
	名称后面加数据库类型后缀来区分，例如：
	sqltest
	sqltest-oracle
	sqltest-derby
	sqltest-mysql
	等等，本配置实例就演示了具体配置方法
 ]]>
	</description>
	<property name="sqltest"><![CDATA[select * from LISTBEAN]]>
	</property>
	<property name="sqltest-oracle"><![CDATA[select * from LISTBEAN]]>
	</property>
	<property name="sqltemplate"><![CDATA[select FIELDNAME from LISTBEAN where FIELDNAME=#[fieldName]]]>
	</property>
	<property name="sqltemplate-oracle"><![CDATA[select FIELDNAME from LISTBEAN where FIELDNAME=#[fieldName]  ]]></property>
	<!-- 动态sql，如果FIELDNAME 不等于null，并且FIELDNAME不为""将FIELDNAME作为查询条件-->
	<property name="dynamicsqltemplate"><![CDATA[select *  from LISTBEAN  where 1=1 
					#if($fieldName && !$fieldName.equals("")) and FIELDNAME = #[fieldName] #end  ]]>
	</property>

	<property name="dynamicsqltemplateid"><![CDATA[select *  from LISTBEAN  where 1=1

	</property>
	
	<property name="updatesqltemplate"><![CDATA[update LISTBEAN  set FIELDNAME = #[fieldName] where id = #[id] ]]>
	</property>
	
	<property name="queryFieldWithSQLParams"><![CDATA[select count(1)  from LISTBEAN ]]>
