in 语句
<isNotEmpty prepend="AND" property="infoKind">
INFO_KIND in ($infoKind$)
</isNotEmpty>
注意($infoKind$)中 使用$而不是#否则得不到想要的查询结果，因为 #1,2# 会被解析成‘1,2’
like 语句
<isNotEmpty prepend=" AND " property="infoNum">
INFO_NUM LIKE '%$infoNum$%'
</isNotEmpty>
多表查询
<select id="query" parameterClass="java.util.HashMap"
