最近在使用Postman测试接口，POST请求发送JSON格式的数据。之前一直风平浪静，没什么问题。不过最近测试一直失败，得到的响应是500内部错误，于是去服务器看错误信息，信息如下：

网上查相关资料说是什么响应消息头的问题，又说是编码的问题，我想了想我的情况应该不是，毕竟之前也是按照这个来的，一直没啥问题。这个异常很清楚，JSON解析失败了，至于为什么会失败，原因让我很无语。

原来最近终端工具从CRT换成了MobaXterm，从生产环境拷贝数据到测试时，竟然发现它在JSON串中加入了两个>符号，这个符号被加在了中文串中，不容易发现，并且使用JSON格式化校验也查不出问题来。 而就是这个藏在中文串中的符号存在，所以导致fastJson解析失败了，我想正是这个字符被加入其中却没有转义的原因。于是我把这两个>字符删掉后，终于成功的调通了接口。

可见，使用fastJSON解析JSON数据时，遇到这些特殊字符，如果不转义，就可能出现此异常。 需要被转义 

">", ">"
"<", "&lt;"
" ", "&nbsp;"
"\"", "&quot;"
"\'", "&#39;"
"\\", "\\\\"
"\n", "\\n"
"\r", "\\r"
Windows下RequestBody里中文格式 JSON 解析报错 大年29, 项目终于完工, 火急火燎的上线部署, 服务器是Windows系统, 项目框架是SpringBoot2.2.11, 打成jar包运行后测试报错, 报错信息如下: JSON parse error : Invalid UTF- 8 middle byte 0xe8; nested exception is com.fasterxml.jackson.databind.
