jsp 页面传的String ：
"[{"prodIndex":1,"catOne":"311","catOneName":"轮式拖拉机","brandId":"3","brand":"东方红","model":"LX600","njName":"轮式拖拉机 LX600 东方红","num":"2","referPrice":0,"referTotalPrice":0}]"
由于双引号会被转义：
[{"prodIndex":1,"catOne":"311","catOneName":"轮式拖拉机","brandId":"3","brand":"东方红","model":"LX600","njName":"轮式拖拉机 LX600 东方红","num":"2","referPrice":0,"referTotalPrice":0}]
这时用gson转出时会提示报错
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Expected ':' at line 1 column 9 path $[0]."

解决办法 使用 StringEscapeUtils 工具类 中 unescapeHtml4 方法 可以转义
String newJson = StringEscapeUtils.unescapeHtml4(jsonStr);
