继承法Spring hateoas methodOn

Question

我试图使用Spring hateoas从抽象控制器解析继承endpoint的URL。

我认为先给出代码会使问题更容易理解。

package com.stackoverflow.question.spring.rest.controllers;

import org.springframework.hateoas.Resource;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

public class AbstractController {


    @RequestMapping(value="/cat", method=RequestMethod.GET)
    public Resource<String> cat() {
        return new Resource<>("cat");
    }
}

package com.stackoverflow.question.spring.rest.controllers;
import static org.springframework.hateoas.mvc.ControllerLinkBuilder.linkTo;
import static org.springframework.hateoas.mvc.ControllerLinkBuilder.methodOn;

import org.springframework.hateoas.Resource;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/test", produces = { "application/json; charset=utf-8" })
public class TestController extends AbstractController {

    @RequestMapping(method = RequestMethod.GET)
    public Resource<String> test() {
        return new Resource<>("test", linkTo(
                methodOn(TestController.class).cat()).withRel("cat"), linkTo(
                methodOn(TestController.class).uglyfix()).withRel("uglyfix"));
    }

    @RequestMapping(value = "/uglyfix", method = RequestMethod.GET)
    public Resource<String> uglyfix() {
        return new Resource<>("ugly fix", linkTo(TestController.class).slash(
                "cat").withRel("cat"));
    }

}

{
    "content": "test",
    "links": [
        {
            "rel": "cat",
            "href": "http://localhost:8080/resources/cat"
        },
        {
            "rel": "uglyfix",
            "href": "http://localhost:8080/resources/test/uglyfix"
        }
    ]
}

{
    "content": "test",
    "links": [
        {
            "rel": "cat",
            "href": "http://localhost:8080/resources/test/cat"
        },
        {
            "rel": "uglyfix",
            "href": "http://localhost:8080/resources/test/uglyfix"
        }
    ]
}

也许在抽象控制器的顶部添加@requestmapping(value=“test”）可以解决我的问题，但我也不想要这个解决方案，因为我希望将我的extends my抽象控制器与多个控制器一起使用。

有没有一个干净的方法来做，我所期待的？

我觉得有点愚蠢，因为我刚刚从0.9.0.release中迁移了Spring Hateoas0.17.0.release，它解决了我的问题。
