2018/04/26-16:28:04 [http-nio-8080-exec-1] ERROR .[Tomcat].[localhost].[/].[dispatcherServlet]- () for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is : not close json text, token : :] with root cause
: not close json text, token : :
The problem is whether the string of a json structure you passed in is added with {}
String str="{\"tagJson\":[{\"type\":\"people\",\"tagName\":[\"Yes\",\"Yes\",\"most\"]},{\"type\":\"ADDR\",\"tagName\":[\"Russian\",\"Uh-huh\",\"Soko\"]},{\"type\":\"General\",\"tagName\":[\"Uh uh\",\"Uh-huh\",\"Aka legal\",\"Uh uh\",\"Wronged\"]}]}";
If {} is not added on both sides, this error will occur
