mybatis中if关于数字的判断

mybatis 中关于数字的判断,如果直接写<if test = "xx == '1' "> </if>,这样即使是xx==‘1’,通常情况下也不会进入判断的。必须如下写:

<select id="getByNameAndPwd" parameterType="String" resultMap="MemberResult">
        select
           *
        from `member`
        <if test="isMerch != '' and isMerch == '1'.toString() " >
            where  `mobile` = #{name} 
            and `password` = #{password}
        </if>
        <if test="isMerch != '' and isMerch == '2'.toString() " >
            where  `name` = #{name}
            and `password` = #{password}
        </if>   
 
</select>
