How can I grab all query parameters in Jersey JaxRS?

Question

I am building a generic web service and need to grab all the query parameters into one string for later parsing. How can I do this?

Answer 1

You can access a single param via @QueryParam("name") or all of the params via the context:

@POST public Response postSomething(@QueryParam("name") String name, @Context UriInfo uriInfo, String content) {      MultivaluedMap<String, String> queryParams = uriInfo.getQueryParameters();       String nameParam = queryParams.getFirst("name"); } 

The key is the @Context jax-rs annotation, which can be used to access:

UriInfo, Request, HttpHeaders, SecurityContext, Providers

Answer 2

The unparsed query part of the request URI can be obtained from the UriInfo object:

@GET public Representation get(@Context UriInfo uriInfo) {   String query = uriInfo.getRequestUri().getQuery();   ... }
