我有一个自定义 IResourceProvider 服务于 Measure (Measure.class)。
在该代码中，我有以下扩展操作。（来自http://hapifhir.io/doc_rest_operations.html#_toc_extended_operations）
@Operation(name = "$humptydumpty")
public org.hl7.fhir.dstu3.model.Bundle acceptHumptyDumpty(HttpServletRequest servletRequest,
@IdParam(optional = true) IdType theId,
@OperationParam(name = "request") org.hl7.fhir.dstu3.model.Measure item) {
String fakeMessage;
if (null == item) {
fakeMessage = "org.hl7.fhir.dstu3.model.Measure item is null. Sad face. :( ";
} else {
fakeMessage = "org.hl7.fhir.dstu3.model.Measure item is not null. Happy face. :) ";
}
Bundle retVal = new Bundle();
retVal.setId(fakeMessage);
return retVal;
}
如果我从
http://hl7.org/fhir/STU3/measure-exclusive-breastfeeding.json.html
邮政
http://localhost:8080/fhir/Measure/MyMeasureName123/ $humptydumpty
一切正常。我回来。
{
"resourceType": "Bundle",
"id": "org.hl7.fhir.dstu3.model.Measure item is not null. Happy face. :) "
}
所以我了解 $myExtendedMethod 如何工作的基础知识。
现在，当我对 .Parameters 尝试相同的操作时......
Java 代码（与上面相同的 MyResourceProvider）
@Operation(name = "$robinhood")
public Bundle acceptRobinHood(HttpServletRequest servletRequest,
@IdParam(optional = true) IdType theId,
@OperationParam(name = "request") org.hl7.fhir.dstu3.model.Parameters item) {
String fakeMessage;
if (null == item) {
fakeMessage = "org.hl7.fhir.dstu3.model.Parameters item is null. Sad face. :( ";
} else {
fakeMessage = "org.hl7.fhir.dstu3.model.Parameters item is not null. Happy face. :) ";
}
Bundle retVal = new Bundle();
retVal.setId(fakeMessage);
return retVal;
}
邮政
http://localhost:8080/fhir/Measure/MyMeasureName123/ $robinhood
我已经从http://hl7.org/fhir/STU3/parameters-example.json发送了“示例” 。
{
"resourceType": "Parameters",
"id": "example",
"parameter": [
{
"name": "start",
"valueDate": "2010-01-01"
},
{
"name": "end",
"resource": {
"resourceType": "Binary",
"contentType": "text/plain",
"content": "VGhpcyBpcyBhIHRlc3QgZXhhbXBsZQ=="
}
}
]
}
如果我发送......最基本的json。
{
"resourceType": "Parameters",
"id": "MyParameterId234"
}
我得到了悲伤的脸。:(
我什么都试过了。
“项目”始终为空。啊，我把这个拿回来了。
{
"resourceType": "Bundle",
"id": "org.hl7.fhir.dstu3.model.Parameters item is null. Sad face. :( "
}
我尝试了很多东西，最后回到“.Measure”只是为了证明我没有疯。
但我不明白为什么一个会填充（.Measure 资源），而另一个（.Parameters）不会。＃帮助

附加：
我为病人做了一个
@Operation(name = "$teddybear")
public org.hl7.fhir.dstu3.model.Bundle acceptTeddyBear(HttpServletRequest servletRequest,
@IdParam(optional = true) IdType theId,
@OperationParam(name = "request") org.hl7.fhir.dstu3.model.Patient item) {
String fakeMessage;
if (null == item) {
fakeMessage = "org.hl7.fhir.dstu3.model.Patient item is null. Sad face. :( ";
} else {
fakeMessage = "org.hl7.fhir.dstu3.model.Patient item is not null. Happy face. :) ";
}
Bundle retVal = new Bundle();
retVal.setId(fakeMessage);
return retVal;
}
邮政
http://localhost:8080/fhir/Measure/MyMeasureName123/ $ teddybear
它工作正常。
{
"resourceType": "Bundle",
"id": "org.hl7.fhir.dstu3.model.Patient item is not null. Happy face. :) "
}
它唯一伤害我的 .Parameters 资源。

根据 James A 的回答和解决提示，我在下面输入了。
变通代码：（也就是变通答案意义上的“答案”）
@Operation(name = "$robinhood")
public Bundle acceptRobinHood(HttpServletRequest servletRequest,
@IdParam(optional = true) IdType theId,
/*@OperationParam(name = "request") org.hl7.fhir.dstu3.model.Parameters item*/ @ResourceParam String theRawBody) {
String fakeMessage;
if (null == theRawBody || StringUtils.isBlank(theRawBody)) {
fakeMessage = "theRawBody is null or isBlank. Sad face. :( ";
} else {
fakeMessage = "theRawBody is not null and is not isBlank. Happy face. :) ";
}
org.hl7.fhir.dstu3.model.Parameters paramsObject = null;
FhirContext ctx = FhirContext.forDstu3();// this.getContext(); /* prefer encapsulated over hard coding, but for SOF, put in the hard code */
IParser parser = ctx.newJsonParser();
IBaseResource res = parser.parseResource(theRawBody);
paramsObject = (org.hl7.fhir.dstu3.model.Parameters) res;
if (null != paramsObject) {
fakeMessage += " org.hl7.fhir.dstu3.model.Parameters was serialized from theRawBody. Super Happy face. :) :)";
}
else
{
fakeMessage += " org.hl7.fhir.dstu3.model.Parameters was NOT serialized from theRawBody (is null). Super Sad face. :( :( ";
}
Bundle retVal = new Bundle();
retVal.setId(fakeMessage);
return retVal;
}
以及执行代码的响应：
{
"resourceType": "Bundle",
"id": "theRawBody is not null and is not isBlank. Happy face. :) org.hl7.fhir.dstu3.model.Parameters was serialized from theRawBody. Super Happy face. :) :)"
}
