关于ResultType取值错误的是（）。

A.<select id="selectPersonCount"resultType="Integer">select count（*）from person</select>
B.<select id="selectPersonCount"resultType="int">select count（*）fromperson</select>
C.<select id="selectPersonCount"resultType="_int">select count（*）fromperson</select>
D.<select id="selectPersonCount"resultType="java.lang.Integer">select count（*）fromperson</select>
