SpringMVC 数组传参

ajax ：traditional 设为 true 使用传统方式浅层序列化

$.ajax(url, {data: param, async: false, dataType: "json", traditional: true}).done(function(data) {
        if (0 == data.code) {
            flag = true;
        } else {
            $.messager.popup(data.message);
            flag = false;
        }
    });

mybatis：批量删除

delete from staff_relations where super_staff_number=#{superStaffNumber} AND staff_number IN
        <foreach collection="staffNumbers" item="item" separator="," open="(" close=")">
            #{item}
        </foreach>
// collection：表示参数类型，参数如果是数组则写成 array，如果是集合则写成 list

DAO

Integer deleteByStaffNumbersAndSuperStaffNumber(@Param("staffNumbers") Integer[] staffNumbers, @Param("superStaffNumber") Integer superStaffNumber);
