1. 报错：

com.fasterxml.jackson.core.JsonParseException: Illegal unquoted character ((CTRL-CHAR, code 9)): has to be escaped using backslash to be included in string value at [Source: (PushbackInputStream); line: 2, column: 21]

2. 导致原因：

测试时是使用swagger测试接口的，下面的 bin 字段的值是复制过来的，bin 的值表面上看是有 空格 的存在，其实是一些 特殊字符, 删除掉特殊字符就可以解决报错了。

向接口中传递json如下

{

  "bin": "B10-41-03  ",  // 此字段值存在特殊字符问题导致的报错

  "equipment": "RF",

  "invtype": "T",

  "isrecount": 0,

  "uname": "RFShuyy",

  "whnum": "DA1H"

}

3. 总结：

字段的值中，若存在 JsonUtil 无法识别的 特殊字符 时，或是后台接收数据对象的数据结构与传入json不一致导致的无法转换，会出现该报错。

只要仔细对照 接口中参数对象 及 传入的json，就可以解决此bug
