RESTEasy @PathParam 与正则表达式映射

不翻译了@PathParam is a parameter annotation which allows you to map variable URI path fragments into your method call.

package com.example.rest.resteasy.service;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/hello")
public class HelloWorldRestService {
	@GET
	@Path("{var:.*}/stuff")
	public Response getStuff(@PathParam("var") String var) {
		String result = "RESTEasy getStuff() is called! pathParam=" + var;
		return Response.status(200).entity(result).build();
	}

	@GET
	@Path("/aaa{param:b+}/{many:.*}/stuff")
	public Response getIt(@PathParam("param") String bs, @PathParam("many") String many) {
		String result = "RESTEasy getIt() is called! pathParam=[param:" + bs + ",many=" + many + "]";
		return Response.status(200).entity(result).build();
	}
}

通过下面的请求，让我们看到参数“param”与参数"many" 对应的@PathParam参数值

request	param	many
/aaabb/some/stuff	bb	some
/aaab/a/lot/of/stuff	b	a/lot/of
