The default proxy service has a conditional routing stage that checks the
2、 value of the requested interest rate in the loan application document. If the interest rate is less than 5%, the loan application is routed to the ManagerLoanReview business service; otherwise it is routed to the NormalLoanProcessor business service.,企业服务总线技术,ESB,天津联怡科技有限公司,Start a new session.- Cr

10、 A transport provider developed with the Transport SDK handles inbound and outbound messages as follows: Inbound messages typically come into Oracle Service Bus from an outside source, such as an HTTP client. The Transport SDK packages the payload and transport level headers, if any, into a generic
11、data structure. The Transport SDK then passes the message, in its generic format, to the Oracle Service Bus pipeline. Outbound messages originate from Oracle Service Bus business services and go to an externally managed endpoint, such as a Web service or JMS queue. The Transport SDK receives a gener
12、ic data structure from the Oracle Service Bus pipeline, converts it to the corresponding transport-specific headers and payload, and sends it out to an external system. The Transport SDK handles outbound and inbound messages independently. An inbound message can be bound to one transport protocol an
13、d bound to a different transport protocol on the outbound endpoint.,企业服务总线技术,ESB,天津联怡科技有限公司,Inbound Messages at Runtime,企业服务总线技术,ESB,天津联怡科技有限公司,Oracle Service Bus Runtime Inbound Messages The sequence diagram in Figure A1 describes the flow of inbound messages through Oracle Service Bus runtime. Fir
14、st, an inbound artifact, such as an HTTP Servlet, intercepts a client request. The transport provider creates a data structure called InboundTransportMessageContext. The message context packages headers from the request into a metadata object, converting the payload from an HTTP stream into a specif
15、ic Oracle Service Bus source object. The transport provider calls the transport manager to receive the message. The transport manager preprocesses the message and passes the message to the Oracle Service Bus runtime for processing. The Oracle Service Bus runtime asks for the message contexts service
16、, service version, and other information. It also asks about the metadata and payload, which are required for processing. The runtime asks the MessageContext to create the response metadata and the response payload, and then calls close(). The response is sent back to the client.,企业服务总线技术,ESB,天津联怡科技有限公司,Outbound Messages at Runtime,企业服务总线技术,ESB,天津联怡科技有限公司,Oracle Service Bus Runtime Outbound Messages The sequence diagram shown in Figure A2 des
