在MyBatis中,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(*) from person</select>
C<select id="selectPersonCount" resultType="_int"> select count(*) from person</select>
D<select id="selectPersonCount" resultType="java.lang.Integer"> select count(*) from person</select>
