JAX-RS: case-insensitive paths

问题

I have anchored REST services/methods to URI template by @Path annotation. It looks like as usual:

@GET
@Path("/message")
@Produces("application/json")
public Response getMessage() { ... }

But my REST service has to be case-insensitive. Now I'm using regular expression in @Path in all my code like that:

@GET
@Path("/{message:[mM][eE][sS][aA][gG][eE]}")
@Produces("application/json")
public Response getMessage() { ... }

This looks weird. Is there something I overlooked in specification (I hope not, see this) or has any of JAX-RS implementations special feature for that? Now I'm using JBoss RESTeasy.

Thanks.

i don't know resteasy, but if it supports all java regex syntax, you could use (?i:message) instead of your pattern.

If you really need to make the api case-insensitive and you're using Apache on the front-end of your site, consider doing it outside of code: define your API with the urls all lowercase and use Mod-Rewrite to change the urls to lowercase when they hit the web server no matter what the client actually sent. This blog post describes how to do this.

Also, the next pattern is working for me:

@Path("/{externalorders: (?i)externalorders}")
