java开发客户端发送请求到服务器端出现这样：JSON parse error: Unexpected character ('}' (code 125)): was expecting

org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unexpected character ('}' (code 125)): was expecting double-quote to start field name; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('}' (code 125)): was expecting double-quote to start field name

是请求过来的json数据最后一个项包含逗号，去掉这个逗号就可以了。
