Jax-rs automatic decode pathparam

Question

I have a jax-rs service which receives a set of parameters in the path, pathparameters. These parameters may be strings containing values not suitable for urls, so they are urle

Answer 1

The automatic encoding of pathparams works as expected. The problem was that %20is used to encode spaces in the url itself, while + is used to encode the query string(the part after the ?). Pathparams are really parts of the URL, so %20 should be used.

Using URI.toAsciiString() instead of UrlEncoder.encode(...) and passing the different parts gives a valid url that is decoded correctly.

Answer 2

Quote from PathParam javadoc:

The value is URL decoded unless this is disabled using the Encoded annotation.
