ibatis 动态sql（Dynamic SQL）

  springside2allOne中ibatis只用几个孤零的ibatis的dao封装，没看到什么demo。
  官网http://wiki.springside.org.cn/display/springside/iBatis的说明也很简略。在Springside中使用ibatis，参考这里，http://leondu.iteye.com/blog/54694。
  IBatisGenericDao中get、getall明显公用一个statement，因此sql是动态的，参考
http://ibatis.apache.org/docs/dotnet/datamapper/ch03s09.html
   个人ibatis配置如下
 

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig  PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"        
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

	<settings 
		cacheModelsEnabled="true"

		maxRequests="32" 
		maxSessions="10"

	/> 
	<sqlMap resource="com/jake/ibatis/conf/attraction-ibatis.xml" />

</sqlMapConfig>
