Question

我在项目中使用spring-boot-1.5.8和spring-boot-hateoas。请在下面找到代码

@SpringBootApplication
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
public class SpringBootK8Application {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootK8Application.class, args);
    }

}

控制器

 @GetMapping("/greeting")
    public ResponseEntity<Greeting> greeting(@RequestParam(value = "name", required = false, defaultValue = "World") String name) {
        Greeting greeting = new Greeting(String.format("Hello, %s!", name));
        greeting.add(linkTo(methodOn(HelloController.class).greeting(name)).withSelfRel());
        Link link = new Link("http://localhost:8080/something").withRel("ACTIONS");
        SuperLink superLink = new SuperLink(link, MediaTypes.HAL_JSON_VALUE,"GET","/v1/books","v1/bookBy");
        greeting.add(superLink);
        return new ResponseEntity<>(greeting, HttpStatus.OK);
    }

实际输出：

{
  "content": "Hello, World!",
  "_links": {
    "self": {
      "href": "http://localhost:9086/greeting?name=World"
    },
    "ACTIONS": {
      "href": "http://localhost:8080/something",
      "template": "http://localhost:8080/something/v1/books",
      "type": "application/hal+json",
      "method": "GET",
      "describedBy": "http://localhost:8080/something/v1/bookBy"
    }
  }
}

预期输出：

{
  "content": "Hello, World!",
  "_links": {
    "self": {
      "href": "http://localhost:9086/greeting?name=World"
    },
    "ACTIONS": [
      "href": "http://localhost:8080/something",
      "template": "http://localhost:8080/something/v1/books",
      "type": "application/hal+json",
      "method": "GET",
      "describedBy": "http://localhost:8080/something/v1/describedBy"
    ]
  }
}

我想将动作显示为数组。如果我在ACTIONS属性中添加多个元素，则它显示数组，但如果我们只有一个元素，则显示为对象。我总是想将该元素显示为数组。任何帮助都是非常可观的。

Spring Boot超媒体将子元素转换为数组而不是对象
