本文介绍了一个具体的前端与后端交互示例，通过一个URL请求传递JSON参数，并展示了如何在Java后端中解析这些参数。具体涉及了前端如何构造URL携带JSON数据，后端如何使用Jackson库来读取和解析这些数据。

前端传到后端的URL：http://cpadmin.beta.ule.com/guan/lujiang/coupon/query.do?message=%7B%22tabType%22%3A%221%22%2C%22channel%22%3A%22All%22%2C%22categoryType%22%3A%2210%22%2C%22pageSize%22%3A%226%22%2C%22pageIndex%22%3A%221%22%2C%22sort%22%3A%22cw_serial_number_app+asc%22%2C%22showType%22%3A%22J%22%7D&_=1491966905636&callback=jsonp3

java后端获取：

String message = request.getParameter("message");
JsonNode jsonNode = JacksonUtil.getJsonNode(message);
String categoryType = JacksonUtil.getString(jsonNode,"categoryType");
String sort = JacksonUtil.getString(jsonNode,"sort");
String tabType = JacksonUtil.getString(jsonNode,"tabType");
String merTypeFlag = JacksonUtil.getString(jsonNode,"merTypeFlag");
String pageSize = JacksonUtil.getString(jsonNode,"pageSize");
String pageIndex = JacksonUtil.getString(jsonNode,"pageIndex");
String storeTypeFlag = JacksonUtil.getString(jsonNode,"storeTypeFlag");
String categoryTypeFlag = JacksonUtil.getString(jsonNode,"categoryTypeFlag");
String rechargeTypeFlag = JacksonUtil.getString(jsonNode,"rechargeTypeFlag");
String freightTypeFlag = JacksonUtil.getString(jsonNode,"freightTypeFlag");
String storeName = JacksonUtil.getString(jsonNode,"storeName");
String shoppingTypeFlag = JacksonUtil.getString(jsonNode,"shoppingTypeFlag");

用到的包：

import org.codehaus.jackson.JsonNode;
