You forgot to specify {appId_} in value = "/apps/users/{username_}"

Fix: value = "/apps/{appId_}/users/{username_}"

~~~

Your method accepts @RequestParam("data") String datas and you're sending data={} String should be quoted so the fix is data=""

Try with fixing 'data' string. – sovas Apr 19 '17 at 13:02
So I need to set something like wise` , @RequestParam("data") String data)`. @sovas I set according you said but still not working. – Nimit Parekh Apr 19 '17 at 13:07
it's working into string but want to pass empty map into GET request.Can you please try to look into my request. – Nimit Parekh Apr 19 '17 at 15:29
So you want to have String data or Map data? – sovas Apr 19 '17 at 16:04
I changed as you said but still not getting the resolution @RequestParam("data") Map data_) – Nimit Parekh Apr 20 '17 at 06:47

This kind of behaviour affect of major update of Tomcat.

For a quick fix, you can downgrade to one of older versions, I downgraded tomcat with 7.0.63 .

After getting more R&D on Spring MVC It's reject the request while adding list of invalid character into request listed below.

Excluded US-ASCII Characters disallowed within the URI syntax:

   control     = <US-ASCII coded characters 00-1F and 7F hexadecimal>
   space       = <US-ASCII coded character 20 hexadecimal>
   delims      = "<" | ">" | "#" | "%" | <">

List of unwise characters are allowed but may cause problems:

unwise      = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"

The following characters are reserved within a query component and have special meaning within a URI/URL:

  reserved    = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | ","

Solution:

encodeURI("http://localhost:28080/restServices/apps/1762/users/USERNAME/?password=PASSWORD&data={}")
> http://localhost:28080/restServices/apps/1762/users/USERNAME/?password=PASSWORD&data=%7B%7D
