  • Constructor Details

    • RestfulServer

      public RestfulServer()
      Constructor. Note that if no FhirContext is passed in to the server (either through the constructor, or through setFhirContext(FhirContext)) the server will determine which version of FHIR to support through classpath scanning. This is brittle, and it is highly recommended to explicitly specify a FHIR version.

    • addHeadersToResponse

      public void addHeadersToResponse(jakarta.servlet.http.HttpServletResponse theHttpResponse)
      This method is called prior to sending a response to incoming requests. It is used to add custom headers.

      Use caution if overriding this method: it is recommended to call super.addHeadersToResponse to avoid inadvertently disabling functionality.

    • getServerBindings

      public List<BaseMethodBinding> getServerBindings()

    • getServerConformanceProvider

      public Object getServerConformanceProvider()
      Returns the server conformance provider, which is the provider that is used to generate the server's conformance (metadata) statement if one has been explicitly defined.

      By default, the ServerConformanceProvider for the declared version of FHIR is used, but this can be changed, or set to null to use the appropriate one for the given FHIR version.

    • setServerConformanceProvider

      public void setServerConformanceProvider(@Nonnull Object theServerConformanceProvider)
      Returns the server conformance provider, which is the provider that is used to generate the server's conformance (metadata) statement.

      By default, the ServerConformanceProvider implementation for the declared version of FHIR is used, but this can be changed, or set to null if you do not wish to export a conformance statement.

      This method should only be called before the server is initialized. Calling it after the server has started is allowed, but you should be very careful in this case that you only call it while no traffic is hitting the server.
      Throws:
      IllegalStateException - Note that this method can only be called prior to initialization and will throw an IllegalStateException if called after that.

    • getServerName

      public String getServerName()

      Subclasses may override this to customize the way that the RequestDetails object is created. Generally speaking, the right way to do this is to override this method, but call the super-implementation (super.newRequestDetails) and then customize the returned object before returning it.
      Parameters:
      theRequestType - The HTTP request verb
      theRequest - The servlet request
      theResponse - The servlet response
      Returns:
      A ServletRequestDetails instance to be passed to any resource providers, interceptors, etc. that are invoked as a part of serving this request.

    • newRequestDetails

      @Deprecated protected ServletRequestDetails newRequestDetails()
      Deprecated.
      Deprecated in HAPI FHIR 4.1.0 - Users wishing to override this method should override newRequestDetails(RequestTypeEnum, HttpServletRequest, HttpServletResponse) instead

      protected void addRequestIdToResponse(ServletRequestDetails theRequestDetails, String theRequestId)

    • getOrCreateRequestId

      protected String getOrCreateRequestId(jakarta.servlet.http.HttpServletRequest theRequest)
      Reads a request ID from the request headers via the Constants.HEADER_REQUEST_ID header, or generates one if none is supplied.

      Note that the generated request ID is a random 64-bit long integer encoded as hexadecimal. It is not generated using any cryptographic algorithms or a secure PRNG, so it should not be used for anything other than troubleshooting purposes.

    • newRequestId

      protected String newRequestId(int theRequestIdLength)
      Generate a new request ID string. Subclasses may ovrride.

    • validateRequest

      protected void validateRequest(ServletRequestDetails theRequestDetails)

    • init

      public final void init() throws jakarta.servlet.ServletException
      Initializes the server. Note that this method is final to avoid accidentally introducing bugs in implementations, but subclasses may put initialization code in initialize(), which is called immediately before beginning initialization of the restful server's internal init.
      Overrides:
      init in class jakarta.servlet.GenericServlet
      Throws:
      jakarta.servlet.ServletException

    • initialize

      protected void initialize() throws jakarta.servlet.ServletException
      This method may be overridden by subclasses to do perform initialization that needs to be performed prior to the server being used.
      Throws:
      jakarta.servlet.ServletException - If the initialization failed. Note that you should consider throwing UnavailableException (which extends ServletException), as this is a flag to the servlet container that the servlet is not usable.

    • isDefaultPrettyPrint

      public boolean isDefaultPrettyPrint()
      Should the server "pretty print" responses by default (requesting clients can always override this default by supplying an Accept header in the request, or a _pretty parameter in the request URL.

      The default is false

      Note that this setting is ignored by ResponseHighlighterInterceptor when streaming HTML, although even when that interceptor it used this setting will still be honoured when streaming raw FHIR.

      Specified by:
      isDefaultPrettyPrint in interface IRestfulServerDefaults
      Returns:
      Returns the default pretty print setting

    • setDefaultPrettyPrint

      Parameters:
      theDefaultPrettyPrint - The default pretty print setting

    • isIgnoreServerParsedRequestParameters

      public boolean isIgnoreServerParsedRequestParameters()
      If set to true (the default is true) this server will not use the parsed request parameters (URL parameters and HTTP POST form contents) but will instead parse these values manually from the request URL and request body.

      This is useful because many servlet containers (e.g. Tomcat, Glassfish) will use ISO-8859-1 encoding to parse escaped URL characters instead of using UTF-8 as is specified by FHIR.

    • setIgnoreServerParsedRequestParameters

      public void setIgnoreServerParsedRequestParameters(boolean theIgnoreServerParsedRequestParameters)
      If set to true (the default is true) this server will not use the parsed request parameters (URL parameters and HTTP POST form contents) but will instead parse these values manually from the request URL and request body.

      This is useful because many servlet containers (e.g. Tomcat, Glassfish) will use ISO-8859-1 encoding to parse escaped URL characters instead of using UTF-8 as is specified by FHIR.

    • isUncompressIncomingContents

      public boolean isUncompressIncomingContents()
      Should the server attempt to decompress incoming request contents (default is true). Typically this should be set to true unless the server has other configuration to deal with decompressing request bodies (e.g. a filter applied to the whole server).

    • setUncompressIncomingContents

      public void setUncompressIncomingContents(boolean theUncompressIncomingContents)
      Should the server attempt to decompress incoming request contents (default is true). Typically this should be set to true unless the server has other configuration to deal with decompressing request bodies (e.g. a filter applied to the whole server).
