<!-- 传递多参数的array参数表的foreach使用 -->
<select id="getStudentAllArray" resultMap="reusltMap_student"
resultType="com.deppon.mybatis.exsiceTest.Student"
parameterType="array">
select * from t_maydel_student where stunum in
<foreach collection="array" index="index" item="item" open="(" separator="," close=")">
#{item}
</foreach>
