<select id="qryUser" resultClass="java.util.HashMap"  parameterClass="java.util.HashMap" >
	SELECT userId  FROM sys_user WHERE 1=1
		<isNotEmpty property="userId">
			AND userId = "#userId#"	
		</isNotEmpty>
	
</select>

以上语句报错了

SqlMapClient operation; SQL [];   \n

查了半天，原来是因为

<isNotEmpty property="userId">
			AND userId = "#userId#"	
		</isNotEmpty>

这个#userId# 外面多了 双引号， 把双引号去掉好了
