本文讨论了DomainResource。

在某些情况下，当您可能想要创建一个完全自定义资源类型。仅当没有此功能时才应使用此功能其他选择，因为这意味着您正在创建一种资源类型将无法与其他FHIR实现互操作。

我已经实现了代码表。（我在下面显示了这些类（为了简洁起见，没有“胆量”）（URL上的完整代码））

/**
 * This is an example of a custom resource that also uses a custom
 * datatype.
 * 
 * Note that we are extensing DomainResource for an STU3
 * resource. For DSTU2 it would be BaseResource. 
 */
@ResourceDef(name = "CustomResource", profile = "http://hl7.org/fhir/profiles/custom-resource")
public class CustomResource extends DomainResource {
}

和

/**
 * This is an example of a custom datatype. 
 * 
 * This is an STU3 example so it extends Type and implements ICompositeType. For
 * DSTU2 it would extend BaseIdentifiableElement and implement ICompositeDatatype.
 */
@DatatypeDef(name="CustomDatatype")
public class CustomDatatype extends Type implements ICompositeType {
}

我已经在我的代码库中“注册了它”：

        if (null != this.fhirContext)
        {
            this.fhirContext.registerCustomType(CustomResource.class);
            this.fhirContext.registerCustomType(CustomDatatype.class);
        }

（〜尝试按照上面的URL中的说明进行操作）

// Create a context. Note that we declare the custom types we'll be using
// on the context before actually using them
FhirContext ctx = FhirContext.forDstu3();
ctx.registerCustomType(CustomResource.class);
ctx.registerCustomType(CustomDatatype.class);

// Now let's create an instance of our custom resource type
// and populate it with some data
CustomResource res = new CustomResource();

// Add some values, including our custom datatype
DateType value0 = new DateType("2015-01-01");
res.getTelevision().add(value0);

CustomDatatype value1 = new CustomDatatype();
value1.setDate(new DateTimeType(new Date()));
value1.setKittens(new StringType("FOO"));
res.getTelevision().add(value1);

res.setDogs(new StringType("Some Dogs"));

// Now let's serialize our instance
String output = ctx.newXmlParser().setPrettyPrint(true).encodeResourceToString(res);
System.out.println(output);

但这看起来就像是控制台应用程序中两个对象的用法……不是如何将其连接到fhir-server。

我已经尝试了3个小时，以找出要使用的URL。

我尝试过的一些事情：

http://127.0.0.1:8080/fhir/CustomResource

http://127.0.0.1:8080/fhir/profiles/custom-resource

http://127.0.0.1:8080/fhir/custom-resource

无济于事...

什么是URL？

如何填充它的值？

Answer 1

好的。

因此，CustomResource仍需要自己的IResourceProvider。（感谢丹尼尔斯在原始问题的评论中）

这是一个基本的工作示例。

您将完成我在原始问题中列出的所有内容，并为新的customresource制作并注册一个IResourceProvider。

新的IResourceProvider

package mystuff.resourceproviders;

import org.hl7.fhir.dstu3.model.DateType;
import org.hl7.fhir.dstu3.model.IdType;
import ca.uhn.fhir.rest.annotation.IdParam;
import ca.uhn.fhir.rest.annotation.Read;
import ca.uhn.fhir.rest.server.IResourceProvider;
import mystuff.CustomDatatype;
import mystuff.CustomResource;
import org.hl7.fhir.dstu3.model.DateTimeType;
import org.hl7.fhir.dstu3.model.StringType;
import org.hl7.fhir.instance.model.api.IBaseResource;

import java.util.Date;

public class CustomResourceProvider implements IResourceProvider {


    @Override
    public Class<? extends IBaseResource> getResourceType() {
        return CustomResource.class;
    }


    /* the IdType (datatype) will be different based on STU2 or STU3.  STU3 version below */
    @Read()
    public CustomResource getResourceById(@IdParam IdType theId) {
        // Now let's create an instance of our custom resource type
        // and populate it with some data
        CustomResource res = new CustomResource();
        res.setId(theId);

        // Add some values, including our custom datatype
        DateType value0 = new DateType("2015-01-01");
        res.getTelevision().add(value0);

        CustomDatatype value1 = new CustomDatatype();
        value1.setDate(new DateTimeType(new Date()));
        value1.setKittens(new StringType("FOO"));
        res.getTelevision().add(value1);

        res.setDogs(new StringType("Some Dogs"));
        return res;
    }
}

然后您将注册此文件（如此处记录）：

http://hapifhir.io/doc_rest_server.html#_toc_create_a_server

代替此：

   @Override
   protected void initialize() throws ServletException {
      /*
       * The servlet defines any number of resource providers, and
       * configures itself to use them by calling
       * setResourceProviders()
       */
      List<IResourceProvider> resourceProviders = new ArrayList<IResourceProvider>();
      resourceProviders.add(new RestfulPatientResourceProvider());
      resourceProviders.add(new RestfulObservationResourceProvider());
      setResourceProviders(resourceProviders);
   }

您将拥有这样的东西

   @Override
   protected void initialize() throws ServletException {
      /*
       * The servlet defines any number of resource providers, and
       * configures itself to use them by calling
       * setResourceProviders()
       */
      List<IResourceProvider> resourceProviders = new ArrayList<IResourceProvider>();
      resourceProviders.add(new CustomResourceProvider());
      setResourceProviders(resourceProviders);
   }

用于测试该网址（最可能的本地开发网址）

http://127.0.0.1:8080/fhir/CustomResource/12345

，您将获得此JSON响应。

{
    "resourceType": "CustomResource",
    "id": "12345",
    "meta": {
        "profile": [
            "http://hl7.org/fhir/profiles/custom-resource"
        ]
    },
    "televisionDate": [
        "2015-01-01"
    ],
    "televisionCustomDatatype": [
        {
            "date": "2019-01-14T11:49:44-05:00",
            "kittens": "FOO"
        }
    ],
    "dogs": "Some Dogs"
}

Hapi Fhir DomainResource，您使用什么URL？
