FHIR

Since Camel 2.23

Both producer and consumer are supported

The FHIR component integrates with the HAPI-FHIR library which is an open-source implementation of the FHIR (Fast Healthcare Interoperability Resources) specification in Java.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-fhir</artifactId>
    <version>${camel-version}</version>
</dependency>

URI Format

The FHIR Component uses the following URI format:

fhir://endpoint-prefix/endpoint?[options]

Endpoint prefix can be one of:

  • capabilities

  • create

  • delete

  • history

  • load-page

  • meta

  • operation

  • patch

  • read

  • search

  • transaction

  • update

  • validate

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

Component Options

The FHIR component supports 27 options, which are listed below.

Name Description Default Type

encoding (common)

Encoding to use for all request.

Enum values:

  • JSON

  • XML

String

fhirVersion (common)

The FHIR Version to use.

Enum values:

  • DSTU2

  • DSTU2_HL7ORG

  • DSTU2_1

  • DSTU3

  • R4

  • R4B

  • R5

R4

String

log (common)

false

boolean

prettyPrint (common)

false

boolean

serverUrl (common)

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component.

Spring Boot Auto-Configuration

When using fhir with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-fhir-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 66 options, which are listed below.

Name Description Default Type

camel.component.fhir.access-token

OAuth access token.

String

camel.component.fhir.autowired-enabled

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

Boolean

camel.component.fhir.bridge-error-handler

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

Boolean

camel.component.fhir.client

To use the custom client. The option is a ca.uhn.fhir.rest.client.api.IGenericClient type.

IGenericClient

camel.component.fhir.client-factory

To use the custom client factory. The option is a ca.uhn.fhir.rest.client.api.IRestfulClientFactory type.

IRestfulClientFactory

camel.component.fhir.compress

Compresses outgoing (POST/PUT) contents to the GZIP format.

false

Boolean

camel.component.fhir.configuration

To use the shared configuration. The option is a org.apache.camel.component.fhir.FhirConfiguration type.

FhirConfiguration

camel.component.fhir.connection-timeout

How long to try and establish the initial TCP connection (in ms).

10000

Integer

camel.component.fhir.defer-model-scanning

When this option is set, model classes will not be scanned for children until the child list for the given type is actually accessed.

false

Boolean

camel.component.fhir.enabled

Whether to enable auto configuration of the fhir component. This is enabled by default.

Boolean

camel.component.fhir.encoding

Encoding to use for all request.

String

camel.component.fhir.fhir-context

FhirContext is an expensive object to create. To avoid creating multiple instances, it can be set directly. The option is a ca.uhn.fhir.context.FhirContext type.

FhirContext

camel.component.fhir.fhir-version

The FHIR Version to use.

R4

String

camel.component.fhir.force-conformance-check

Force conformance check.

false

Boolean

camel.component.fhir.lazy-start-producer

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

Boolean

camel.component.fhir.log

Will log every requests and responses.

false

Boolean

camel.component.fhir.password

Password to use for basic authentication.

String

camel.dataformat.fhir-json.content-type-header

Whether the data format should set the Content-Type header with the type from the data format. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON.

true

Boolean

camel.dataformat.fhir-json.dont-encode-elements

If provided, specifies the elements which should NOT be encoded. Multiple elements can be separated by comma when using String parameter. Valid values for this field would include: Patient - Don’t encode patient and all its children Patient.name - Don’t encode the patient’s name Patient.name.family - Don’t encode the patient’s family name .text - Don’t encode the text element on any resource (only the very first position may contain a wildcard) DSTU2 note: Note that values including meta, such as Patient.meta will work for DSTU2 parsers, but values with subelements on meta such as Patient.meta.lastUpdated will only work in DSTU3 mode.

String

camel.dataformat.fhir-json.dont-strip-versions-from-references-at-paths

If supplied value(s), any resource references at the specified paths will have their resource versions encoded instead of being automatically stripped during the encoding process. This setting has no effect on the parsing process. Multiple elements can be separated by comma when using String parameter. This method provides a finer-grained level of control than setStripVersionsFromReferences(String) and any paths specified by this method will be encoded even if setStripVersionsFromReferences(String) has been set to true (which is the default).

String

camel.dataformat.fhir-json.enabled

Whether to enable auto configuration of the fhirJson data format. This is enabled by default.

Boolean

camel.dataformat.fhir-json.encode-elements

If provided, specifies the elements which should be encoded, to the exclusion of all others. Multiple elements can be separated by comma when using String parameter. Valid values for this field would include: Patient - Encode patient and all its children Patient.name - Encode only the patient’s name Patient.name.family - Encode only the patient’s family name .text - Encode the text element on any resource (only the very first position may contain a wildcard) .(mandatory) - This is a special case which causes any mandatory fields (min 0) to be encoded.

String

camel.dataformat.fhir-json.encode-elements-applies-to-child-resources-only

If set to true (default is false), the values supplied to setEncodeElements(Set) will not be applied to the root resource (typically a Bundle), but will be applied to any sub-resources contained within it (i.e. search result resources in that bundle).

false

Boolean

camel.dataformat.fhir-json.fhir-context

To use a custom fhir context. Reference to object of type ca.uhn.fhir.context.FhirContext.

String

camel.dataformat.fhir-json.fhir-version

The version of FHIR to use. Possible values are: DSTU2,DSTU2_HL7ORG,DSTU2_1,DSTU3,R4,R5.

R4

String

camel.dataformat.fhir-json.force-resource-id

When encoding, force this resource ID to be encoded as the resource ID. Reference to object of type org.hl7.fhir.instance.model.api.IIdType.

String

camel.dataformat.fhir-json.omit-resource-id

If set to true (default is false) the ID of any resources being encoded will not be included in the output. Note that this does not apply to contained resources, only to root resources. In other words, if this is set to true, contained resources will still have local IDs but the outer/containing ID will not have an ID.

false

Boolean

camel.dataformat.fhir-json.override-resource-id-with-bundle-entry-full-url

If set to true (which is the default), the Bundle.entry.fullUrl will override the Bundle.entry.resource’s resource id if the fullUrl is defined. This behavior happens when parsing the source data into a Bundle object. Set this to false if this is not the desired behavior (e.g. the client code wishes to perform additional validation checks between the fullUrl and the resource id).

false

Boolean

camel.dataformat.fhir-json.parser-error-handler

Registers an error handler which will be invoked when any parse errors are found. Reference to object of type ca.uhn.fhir.parser.IParserErrorHandler.

String

camel.dataformat.fhir-json.parser-options

Sets the parser options object which will be used to supply default options to newly created parsers. Reference to object of type ca.uhn.fhir.context.ParserOptions.

String

camel.dataformat.fhir-json.prefer-types

If set (FQN class names), when parsing resources the parser will try to use the given types when possible, in the order that they are provided (from highest to lowest priority). For example, if a custom type which declares to implement the Patient resource is passed in here, and the parser is parsing a Bundle containing a Patient resource, the parser will use the given custom type. Multiple class names can be separated by comma.

String

camel.dataformat.fhir-json.pretty-print

Sets the pretty print flag, meaning that the parser will encode resources with human-readable spacing and newlines between elements instead of condensing output as much as possible.

false

Boolean

camel.dataformat.fhir-json.server-base-url

Sets the server’s base URL used by this parser. If a value is set, resource references will be turned into relative references if they are provided as absolute URLs but have a base matching the given base.

String

camel.dataformat.fhir-json.strip-versions-from-references

If set to true (which is the default), resource references containing a version will have the version removed when the resource is encoded. This is generally good behaviour because in most situations, references from one resource to another should be to the resource by ID, not by ID and version. In some cases though, it may be desirable to preserve the version in resource links. In that case, this value should be set to false. This method provides the ability to globally disable reference encoding. If finer-grained control is needed, use setDontStripVersionsFromReferencesAtPaths(List).

false

Boolean

camel.dataformat.fhir-json.summary-mode

If set to true (default is false) only elements marked by the FHIR specification as being summary elements will be included.

false

Boolean

camel.dataformat.fhir-json.suppress-narratives

If set to true (default is false), narratives will not be included in the encoded values.

false

Boolean

camel.dataformat.fhir-xml.content-type-header

Whether the data format should set the Content-Type header with the type from the data format. For example application/xml for data formats marshalling to XML, or application/json for data formats marshalling to JSON.

true

Boolean

camel.dataformat.fhir-xml.dont-encode-elements

If provided, specifies the elements which should NOT be encoded. Multiple elements can be separated by comma when using String parameter. Valid values for this field would include: Patient - Don’t encode patient and all its children Patient.name - Don’t encode the patient’s name Patient.name.family - Don’t encode the patient’s family name .text - Don’t encode the text element on any resource (only the very first position may contain a wildcard) DSTU2 note: Note that values including meta, such as Patient.meta will work for DSTU2 parsers, but values with subelements on meta such as Patient.meta.lastUpdated will only work in DSTU3 mode.
