I have a html table that I am converting to json format and sending to my POST type server. Given below is the ajax call to send the data to the url.

$.ajax({
   url: "http://localhost:8090/DocVaccine",
   contentType: "application/json",
   type: 'POST',
   data: JSON.stringify(convertTableToJson()),
   success: function (data) {
       alert("DATA SENT");
   }
 });

On receiving the data, (which is in string format) i simply print to check its format.

 @RequestMapping(
        value = "/DocVaccine", 
        method=RequestMethod.POST, headers = "Accept=*/*",
        produces = "application/json", consumes="application/json")
    public void UpdateVaccineCard(@RequestBody String p1) throws IOException 
   {
        LOGGER.info(p1);
    }

this is the output i get. How do i convert this into java object? I have a vaccine class which defines all the headers such as id, dueDate, dateGiven, etc. I need to convert this into proper json format to store into my mongo database.
