错误原因的所在！是OGNL的语法问题，这里'Y'将被认为是char类型的数据，但是'YY'或者“Y”将被认为是String类型的数据，解决方案如下所示：

1：将代码改为test="param eq 'Y'.toString()"

2：将代码改为test="name == "Y""

3：将代码改为test='index == "Y"'

修改后：
 <if test="accom_state != null and accom_state == 'Y'.toString()">
AND asa.accom_state IN ('S','Y','X')

 </if>

 <if test="accom_state != null and accom_state == 'N'.toString()">
 AND asa.accom_state  ='N'

</if>
