Spring HATEOAS&HAL:在_embedded中更改数组名称

Question

我正在尝试使用Spring HATEOAS构建符合HAL的REST API.

在一些摆弄之后,我设法开始工作,大多是预期的.(样本)输出现在看起来像这样:

{
    "_links": {
        "self": {
            "href": "http://localhost:8080/sybil/configuration/bricks"
        }
    },
    "_embedded": {
        "brickDomainList": [
            {
                "hostname": "localhost",
                "port": 4223,
                "_links": {
                    "self": {
                        "href": "http://localhost:8080/sybil/configuration/bricks/localhost"
                    }
                }
            },
            {
                "hostname": "synerforge001",
                "port": 4223,
                "_links": {
                    "self": {
                        "href": "http://localhost:8080/sybil/configuration/bricks/synerforge001"
                    }
                }
            }
        ]
    }
}

我不喜欢"brickDomainList"数组的名称.理想情况下应该说"砖块".我该怎么改变它？

这是产生输出的控制器:

@RestController
@RequestMapping("/configuration/bricks")
public class ConfigurationBricksController {

    private BrickRepository brickRepository;
    private GraphDatabaseService graphDatabaseService;

    @Autowired
    public ConfigurationBricksController(BrickRepository brickRepository, GraphDatabaseService graphDatabaseService) {

        this.brickRepository = brickRepository;
        this.graphDatabaseService = graphDatabaseService;
    }

    @ResponseBody
    @RequestMapping(method = RequestMethod.GET, produces = "application/hal+json")
    public Resources<BrickResource> bricks() {

        List<BrickDomain> bricks;
        List<BrickResource> resources = new ArrayList<>();
        List<Link> links = new ArrayList<>();

        Link self = linkTo(ConfigurationBricksController.class).withSelfRel();
        links.add(self);

        try(Transaction tx = graphDatabaseService.beginTx()) { // begin transaction

            // get all Bricks from database and cast them into a list so that they're actually fetched
            bricks = new ArrayList<>(IteratorUtil.asCollection(brickRepository.findAll()));

            // end transaction
            tx.success();
        }

        for (BrickDomain brick : bricks) {
            self = linkTo(methodOn(ConfigurationBricksController.class).brick(brick.getHostname())).withSelfRel();

            BrickResource resource = new BrickResource(brick, self);

            resources.add(resource);
        }

        return new Resources<>(resources, links);
    }
}

是否有一些注释或我可以添加的内容来更改数组的名称？

如果您想要/需要查看BrickResource类或存储库或其他内容,请访问:https://github.com/ttheuer/sybil/tree/mvctest/src/main/java/org/synyx/sybil

BrickResource位于api/resources /中,存储库位于database /中,而BrickDomain位于domain /中.

谢谢!

只需使用Evo Inflector.如果您有Maven项目,则添加依赖项

<dependency>
  <groupId>org.atteo</groupId>
  <artifactId>evo-inflector</artifactId>
  <version>1.2</version>
</dependency>

或者您可以添加@Relation(collectionRelation = "bricks")到BrickDomain课程中

@Relation(collectionRelation = "bricks")
public class BrickDomain { … }
