140.10. Example 3: Handling Requests from SAP

Overview
링크 복사

This example demonstrates a route which handles a request from SAP to the BOOK_FLIGHT RFC, which is implemented by the route. In addition, it demonstrates the component's XML serialization support, using JAXB to unmarshal and marshal SAP request objects and response objects to custom beans.
This route creates a FlightTrip business object on behalf of a travel agent, FlightCustomer. The route first unmarshals the SAP request object received by the SAP server endpoint into a custom JAXB bean. This custom bean is then multicasted in the exchange to three sub-routes, which gather the travel agent, flight connection and passenger information required to create the flight trip. The final sub-route creates the flight trip object in SAP as demonstrated in the previous example. The final sub-route also creates and returns a custom JAXB bean which is marshaled into an SAP response object and returned by the server endpoint.

Java DSL for route

The Java DSL for the example route is as follows: 
DataFormat jaxb = new JaxbDataFormat("org.fusesource.sap.example.jaxb");

from("sap-srfc-server:nplserver:BOOK_FLIGHT")
    .unmarshal(jaxb)
    .multicast()
    .to("direct:getFlightConnectionInfo", 
        "direct:getFlightCustomerInfo", 
        "direct:getPassengerInfo")
    .end()
    .to("direct:createFlightTrip")
    .marshal(jaxb);

XML DSL for route

And the XML DSL for the same route is as follows: 
<route>
    <from uri="sap-srfc-server:nplserver:BOOK_FLIGHT"/>
    <unmarshal>
        <jaxb contextPath="org.fusesource.sap.example.jaxb"/>
    </unmarshal>
    <multicast>
        <to uri="direct:getFlightConnectionInfo"/>
        <to uri="direct:getFlightCustomerInfo"/>
        <to uri="direct:getPassengerInfo"/>
    </multicast>
    <to uri="direct:createFlightTrip"/>
    <marshal>
        <jaxb contextPath="org.fusesource.sap.example.jaxb"/>
    </marshal>
</route>

The following listing illustrates a JAXB bean which unmarshals from the serialized form of an SAP BOOK_FLIGHT request object: 
@XmlRootElement(name="Request", namespace="http://sap.fusesource.org/rfc/nplServer/BOOK_FLIGHT")
@XmlAccessorType(XmlAccessType.FIELD)
public class BookFlightRequest {
    
    @XmlAttribute(name="CUSTNAME")
    private String customerName;
    
    @XmlAttribute(name="FLIGHTDATE")
    @XmlJavaTypeAdapter(DateAdapter.class)
    private Date flightDate;
    
    @XmlAttribute(name="TRAVELAGENCYNUMBER")
    private String travelAgencyNumber;
    
    @XmlAttribute(name="DESTINATION_FROM")
    private String startAirportCode;
    
    @XmlAttribute(name="DESTINATION_TO")
    private String endAirportCode;
    
    @XmlAttribute(name="PASSFORM")
    private String passengerFormOfAddress;
    
    @XmlAttribute(name="PASSNAME")
    private String passengerName;

The following listing illustrates a JAXB bean which marshals to the serialized form of an SAP BOOK_FLIGHT response object: 
@XmlRootElement(name="Response", namespace="http://sap.fusesource.org/rfc/nplServer/BOOK_FLIGHT")
@XmlAccessorType(XmlAccessType.FIELD)
public class BookFlightResponse {
    
    @XmlAttribute(name="TRIPNUMBER")
    private String tripNumber;

    @XmlAttribute(name="TICKET_PRICE")
    private BigDecimal ticketPrice;
    
    @XmlAttribute(name="TICKET_TAX")
    private BigDecimal ticketTax;
    
    @XmlAttribute(name="CURRENCY")
    private String currency;

    @XmlAttribute(name="PASSFORM")
    private String passengerFormOfAddress;
    
    @XmlAttribute(name="PASSNAME")
    private String passengerName;
    
    @XmlAttribute(name="PASSBIRTH")
    @XmlJavaTypeAdapter(DateAdapter.class)
    private Date passengerDateOfBirth;
    
    @XmlElement(name="FLTINFO")
    private FlightInfo flightInfo;

    @XmlElement(name="CONNINFO")
    private ConnectionInfoTable connectionInfo;

The complex parameter fields of the response object are serialized as child elements of the response.

FlightInfo bean

The following listing illustrates a JAXB bean which marshals to the serialized form of the complex table parameter, CONNINFO. Note that the name of the root element type of the JAXB bean corresponds to the name of the row structure type suffixed with _TABLE and the bean contains a list of row elements. 
@XmlRootElement(name="CONNINFO_TABLE", namespace="http://sap.fusesource.org/rfc/nplServer/BOOK_FLIGHT")
@XmlAccessorType(XmlAccessType.FIELD)
public class ConnectionInfoTable {
    
    @XmlElement(name="row")
    List<ConnectionInfo> rows;
