Detailed Description
The basic idea of the invention is as follows: the service bus receives service request messages of various protocol types sent by a client unit and carries out format conversion on the service request messages; a service unit for sending the service request message after format conversion to a service request message request; and the service bus receives a response message returned by the service unit, converts the format of the response message and then sends the response message to the client unit.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
Fig. 1 shows a flow of implementing the method for providing services by using the service bus of the present invention, and as shown in fig. 1, the method includes the following steps:
here, when a user needs to access a certain application, a service request message is input through the client unit, and the client unit sends the service request message input by the user to the service bus;
the Service bus receives a Service request Message of a Java Message Service (JMS) protocol type or a Remote Method Invocation (RMI) protocol type sent by a client unit; converting the service request message of the JMS Protocol type or the RMI Protocol type into a service request message of a Simple Object Access Protocol (SOAP) type; specifically, the message format, communication mode, encoding format, etc. of the service request message are converted into the protocol type supported by the respective requested service unit.
102, the service bus sends the service request message after format conversion to a service unit requested by the service request message;
specifically, in this step, the service bus sends the service request message to a corresponding specific service unit according to a service unit requested by the service request message after format conversion;
and after receiving the service request message, the service unit performs message verification and returns a specific response message to the service bus according to the content of the service request message.
103, the service bus receives a response message returned by the service unit, performs format conversion on the response message, and sends the response message to the client unit;
here, the service bus converts the SOAP type response message into a JMS protocol type or RMI protocol type response message according to the protocol type of the client corresponding to the destination address in the response message, and sends the response message to the corresponding client unit; in particular, the message format, communication mode, encoding format, etc. of the response message are converted into the protocol type applied by the client unit.
The conversion among different protocol types of the service request message is specifically as follows: when the service request message is converted between the JMS protocol type and the SOAP type, because the messages of the JMS protocol type and the SOAP type are based on HTTP and only have different message formats, a simpler mode is to encapsulate the SOAP type message into the message body of the JMS protocol type message, and when the message is converted back, the encapsulation of the JMS protocol type message can be directly removed, so that the SOAP type message is obtained; certainly, in order to improve the working efficiency, the conversion between the message types can be performed by a conversion mode which is more complicated than the above conversion mode, for example, the form XML over JMS Service transmitted inside the Service can be packaged into Web Service, so that the partner or the client can call the Service from the outside; further, when the JMS Service can differentiate the priority of the Service request, the packaged Web Service also needs to support the capability of differentiating the priority of the Service request;
here, the JMS Service prioritizes the Service request by the JMS _ Priority attribute in the JMS header. Correspondingly, defining an element for identifying the priority in the SOAP message header of the Web service, so that the SOAP type service request message is correspondingly complex; specifically, when a message header for indicating that the service Priority is 2 is added to the SOAP message, when the SOAP message is converted into the JMS protocol type message, it is necessary to first extract the value of the service Priority, set the value in JMS _ Priority in the message header of the JMS protocol type message to 2, and then encapsulate the field in the SOAP message body in the JMS message body, so that seamless docking of the SOAP type message and the JMS protocol type message is achieved.
It will be appreciated that there are other ways of converting between the service request message types described above, such as introducing a unified standard data object that can be equivalently interchanged with any regular data or object, by intermediating this data object for format conversion between the various different message types.
Fig. 2 shows a structure of a system for providing a service by a service bus according to the present invention, fig. 3 is a schematic structural diagram of an adaptation unit included in the service bus in the system shown in fig. 2, and as shown in fig. 2 and fig. 3, the system for providing a service by a service bus includes a client unit and a service unit, and further includes: a service bus; the client unit in fig. 2 is schematically illustrated by a Web client unit supporting a Web service related protocol, an RMI client unit supporting an RMI protocol, and a JMS client unit supporting a JMS protocol; correspondingly, the service unit is a Web service unit supporting Web service related protocols, an RMI service unit supporting RMI protocols and a JMS service unit supporting JMS protocols;
it should be understood that the client unit and the service unit may also include client units and service units, respectively, that support other protocol types.

and the sending module is used for sending the SOAP type service request message sent by the conversion module through the unified message routing module to the corresponding service unit.
And the receiving module of the adaptation unit is used for receiving the response message of the SOAP type returned by the service unit.
Further, the receiving module is configured to receive a response message returned by the service unit;
the conversion module is used for converting the response message of the SOAP type into the response message of the JMS protocol type or the RMI protocol type according to the protocol type of the client corresponding to the destination address in the response message sent by the receiving module through the unified message routing module;
and the sending module is used for sending the response message sent by the conversion module through the unified message routing module to the corresponding client unit.
It should be understood that, in the present invention, all messages interacted between the receiving module and the conversion module and all messages interacted between the sending module and the conversion module of the adaptation unit are transmitted to the unified message routing module through the transmission channel, and then transmitted to the other party for interaction through the transmission channel by the unified message routing module. Therefore, by using the unified message routing module as the entrance and exit of the aggregated message, all messages can have the same entrance and exit, the reusability of each functional module is well improved, and unnecessary complexity can be avoided.
