Jersey: Consume all POST data into one object

问题

I am using Jersey 1.8 in my application. I am trying to consume POST data at the server. The data is of the type application/x-www-form-urlencoded. Is there a method to get all the data in one object, maybe a Map<String, Object>.

I ran into Jersey's @Consumes(MediaType.APPLICATION_FORM_URLENCODED). But using this would require me to use @FormParam, which can be tedious if the number of parameters are huge. Or maybe one way is this:

    @POST
    @Path("/urienodedeample")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @Produces(MediaType.APPLICATION_JSON)
    public Response uriEncodedExample(String uriInfo){
        logger.info(uriInfo);
        //process data
        return Response.status(200).build();
    }

The above code consumes and presents the form data in a String object.

_search=false&nd=1373722302667&rows=10&page=1&sidx=email&sord=desc

Processing this can be error prone as any misplaced & and split() will return corrupt data.

I used UriInfo for most of my work which would give me the query parameters in a MultiValuedMap or for other POST requests, sent the payload in json format which would in turn be unmarshalled into a Map<String, Object>. Any suggestions on how I can do the same if the POST data is of the type application/x-www-form-urlencoded.

Got it. As per this document, I can use a MultivaluedMap<K,V> or Form to get all the POST data of the type application/x-www-form-urlencoded in one object. A working exmple:

    @POST
    @Path("/urienodedeample")
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @Produces(MediaType.APPLICATION_JSON)
    public Response uriEncodedExample(MultivaluedMap<String,String> multivaluedMap) {
        logger.info(multivaluedMap);
        return Response.status(200).build();
    }

For cases where the Content-Type is multipart/form-data, this MultivaluedMap approach won't work.

Use FormDataMultiPart - docs here.
