当传入数据只有一个时mybatis中判断会出现There is no getter for property named ‘subjectId’ in ‘class java.lang.Integer

用”_parameter”代替当前参数

正确：

select subjectId,subjectName

from ts_subject

where subjectParentId= 0

and subjectId = #{_parameter,jdbcType=INTEGER}

</if>

</select>

错误：

select subjectId,subjectName

from ts_subject

where subjectParentId= 0

and subjectId = #{subjectId,jdbcType=INTEGER}

</if>

</select>

这时候就会出现异常.

1	There is no getter for property named 'subjectId' in 'class java.lang.Integer
