but when i execute the Request with curl the debuger does not step into the function.
C:\Users\pk>curl -H "Content-Type:application/json" -d {"date":1425811355985,"de
scr":null,"deviceID":"1","provider":"fused","id":0,"lat":4.0,"userid":1,"lon":4.
0} http://127.0.0.1:8080/TblGps/update
The curl output is: just nothing
It seems linke the debugger is not properly attached to the process but when i change my curl request to bad mapping entry STS is showing me the errors on the console debugging windows.
any Ideas appreciated !!

#Controller
public class TblGpsController {
private static final Logger logger = LoggerFactory.getLogger(TblGpsController.class);
#RequestMapping(value = "*", method = { RequestMethod.GET, RequestMethod.POST ,RequestMethod.DELETE,RequestMethod.PUT,RequestMethod.HEAD })
#ResponseBody
public String allFallback() {
return "Fallback for All Requests";
}
#RequestMapping(value="/TblGps/update", method=RequestMethod.POST,consumes = MediaType.ALL_VALUE,produces= MediaType.ALL_VALUE)
#ResponseBody public TblGps post(#RequestParam("object") TblGps gps){
return Application.DataRepository.save(gps);
}

Answer 1

You need to use #RequestParam annotation if you are posting JSON data. Its annotation that needs to be used if you want to parse the data in the request body which in your case is json data sent as post.
#ResponseBody public TblGps post(#RequestBody TblGps gps){
return Application.DataRepository.save(gps);
}
