假设我有两个存储库:
@RepositoryRestResource(collectionResourceRel = "person", path = "person") public interface PersonRepository extends PagingAndSortingRepository<Person, Long> { List<Person> findByLastName(@Param("name") String name); }
和
@RepositoryRestResource(collectionResourceRel = "person1", path = "person1") public interface PersonRepository1 extends PagingAndSortingRepository<Person1, Long> { List<Person1> findByLastName(@Param("name") String name); }
一个常规控制器:
@Controller public class HelloController { @RequestMapping("/hello") @ResponseBody public HttpEntity<Hello> hello(@RequestParam(value = "name", required = false, defaultValue = "World") String name) { Hello hello = new Hello(String.format("Hello, %s!", name)); hello.add(linkTo(methodOn(HelloController.class).hello(name)).withSelfRel()); return new ResponseEntity<>(hello, HttpStatus.OK); } }
现在,对的响应http://localhost:8080/是:
http://localhost:8080/
{ "_links" : { "person" : { "href" : "http://localhost:8080/person{?page,size,sort}", "templated" : true }, "person1" : { "href" : "http://localhost:8080/person1{?page,size,sort}", "templated" : true } } }
但我想得到这样的东西:
{ "_links" : { "person" : { "href" : "http://localhost:8080/person{?page,size,sort}", "templated" : true }, "person1" : { "href" : "http://localhost:8080/person1{?page,size,sort}", "templated" : true }, "hello" : { "href" : "http://localhost:8080/hello?name=World" } } }
@Component public class HelloResourceProcessor implements ResourceProcessor {
@Override public RepositoryLinksResource process(RepositoryLinksResource resource) { resource.add(ControllerLinkBuilder.linkTo(HelloController.class).withRel("hello")); return resource; } }
