优化：基于阿里巴巴 Java 开发手册(黄山版)优化 Jackson 超大整数配置

1.编程规约>前后端规约>第6条：
【强制】对于需要使用超大整数的场景，服务端一律使用 String 字符串类型返回，禁止使用 Long 类型。
说明：Java 服务端如果直接返回 Long 整型数据给前端，Javascript 会自动转换为 Number 类型（注：此类型为双精度浮点数，表示原理与取值范围等同于 Java 中的 Double）。Long 类型能表示的最大值是 263-1，在取值范围之内，超过 253（9007199254740992）的数值转化为Javascript 的 Number 时，有些数值会产生精度损失。
扩展说明，在 Long 取值范围内，任何 2 的指数次的整数都是绝对不会存在精度损失的，所以说精度损失是一个概率问题。若浮点数尾数位与指数位空间不限，则可以精确表示任何整数，但很不幸，双精度浮点数的尾数位只有 52 位。
反例：通常在订单号或交易号大于等于 16 位，大概率会出现前后端订单数据不一致的情况。比如，后端传输的 "orderId"：362909601374617692，前端拿到的值却是：362909601374617660
