错误:There is no getter for property named 'page' in 'class java.lang.Long'

如果传入类型为Long类型,则参数需统一修改为[_parameter],修改后的sql语句如下(不管你的参数是什么,都要改成"_parameter")

 <select id="" parameterType="java.lang.Long" resultType="">
    SELECT * from c c
    <where>
        <if test="accountId!=null">
            c.accountId=#{_parameter} and c.type=2
       </if>
    </where>   
</select>
