How to explicitly obtain post data in Spring MVC

Question

Is there a way to obtain the post data itself  I know spring handles binding post data to java objects  But  given two fields that I want to process  how can I obtain that data   For example  suppose my form had two fields     lt input type  text  name  value1  id  value1   gt    lt input type  text  name  value2  id  value2   gt    How would I go about retrieving those values in my controller

If you are using one of the built-in controller instances, then one of the parameters to your controller method will be the Request object. You can call request.getParameter("value1") to get the POST (or PUT) data value.

If you are using Spring MVC annotations, you can add an annotated parameter to your method's parameters:

@RequestMapping(value = "/someUrl")
public String someMethod(@RequestParam("value1") String valueOne) {
 //do stuff with valueOne variable here
}

Another answer to the OP s exact question is to set the consumes content type to  text plain  and then declare a  RequestBody String input parameter  This will pass the text of the POST data in as the declared String variable  postPayload in the following example    Of course  this presumes your POST payload is text data  as the OP stated was the case    Example        RequestMapping value     your url here   method   RequestMethod POST  consumes    text plain       public ModelAndView someMethod  RequestBody String postPayload

Spring MVC runs on top of the Servlet API  So  you can use HttpServletRequest getParameter   for this   String value1   request getParameter  value1    String value2   request getParameter  value2      The HttpServletRequest should already be available to you inside Spring MVC as one of the method arguments of the handleRequest   method

You can simply just pass the attribute you want without any annotations in your controller   RequestMapping value    quot  someUrl quot   public String someMethod String valueOne       do stuff with valueOne variable here    Works with GET and POST
