Described workflow server assembly is a module of being responsible for receiving and transmitting the http request, it also is in charge of and call flow parsing module and workflow management module, the flow process parsing module is responsible for procedure configuration files resolved and is converted to the flow data structure, and the workflow management module manages flow data structure graftabl.
Initialization flowchart of the present invention is seen Fig. 2.Behind the web startup of server, the flow process server component is carried out initialization, at this moment, the method for workflow server assembly meeting call flow parsing module loads and the process of analysis configuration file, and the flow process parsing module converts procedure configuration files to corresponding flow data structure; The method of workflow server component call workflow management module goes to load the flow data structure then, and this moment, the flow data structure will be stored in the server memory.
Operation flow implementation of the present invention as shown in Figure 3, when the last HTTP request of Internet arrives, server is given the workflow server assembly with HTTP request and subsidiary data and is transmitted, workflow server component call workflow management module asks to resolve to HTTP, search corresponding flow data unit according to the identifier in the attached data, the data transfer device of the flow process Cell processor module that the flow process cell call self is disposed, data are converted to suitable type give flow process unit business module access point, the business module access point is submitted to concrete business module with data and is carried out.The data that business module returns after carrying out will be submitted to flow process unit business module access point, give flow process Cell processor module again and carry out following process.After the flow process Cell processor completion of processing, data and HTTP request forwarding can be returned the workflow server assembly, the workflow server assembly carries out page jump according to the URL type decided of HTTP request again and still starts next flow process.
According to the example of Fig. 4, demonstrate a concrete implementation process below.
Such operation flow is arranged, the client at first fills in list FORM at p1.jsp, list is handled by a business module BO1 who disposes among the mule ESB, return the OBJ1 object after the BO1 resume module is intact, if the attribute1 attribute of OBJ1 is less than 0, then flow process jumps to p3.jsp, otherwise the OBJ1 object is stored in the session so that the processing of the jsp2. page jumps to p2.jsp.
P2.jsp can generate a FORM2 list according to some users' operation, after single user submits to, FORM2 will be converted to a MAP object, give the process (MAP of BO2 then in the lump together with original OBJ1 object in session, OBJ1) method is handled, BO2 is a module that is configured among the SPRING, the intact OBJ2 of this resume module does not return any data, but it is unusual to dish out in processing procedure, unusual if dish out, then flow process jumps to p5.jsp, if all are normal, then jump to p4.jsp, flow process finishes.
In implementing performance history, at first carry out the configuration effort of some flow file:
Creating a procedure configuration files and state a business configuration element, is operation flow element of this business configuration element declaration then, defines the inlet sign of this operation flow element.
This operation flow element relates to the business that two pages are submitted data to, therefore need provide two flow process unity elements, is respectively this two flow process unity element designated identification.Two flow process unity elements all have different data translation tasks, so want the configuration flow Cell processor, the foreground developer with exchange by summary design or with the backstage developer, learn the data that the backstage business module needs, the data transfer device of realization flow Cell processor interface just is configured to the flow process Cell processor in the flow process unity element then.Two flow process unity elements will use the different business module respectively, therefore want configuring service module access point, designated module title and call method.All there is the situation of redirect two flow process unit, thus to dispose the redirect element, and specify redirect sign and path.So just configured procedure configuration files.And the foreground developer is in design during the page, is set to corresponding process identification will triggering professional hyperlink URL (specifying the action value of list during as submission form), just can trigger corresponding flow process.
Write procedure configuration files, just can on server, map out the work, when starting server, according to initial work shown in Figure 2 procedure configuration files has been converted to the flow data structure and is stored in the internal memory.
Example when sketching service operation in conjunction with Fig. 3:
Filled in the list of p1.jsp as the user, when clicking submit button, browser can send to server together with the content of this list and the sign of flow process with the HTTP request, server is transmitted to the workflow server assembly that configures with the HTTP request, this process identification of workflow server assembly notification streams thread management module parses, flow data structure in the workflow management module audit memory, find out the target flow process and the flow process unit of this HTTP request, start corresponding business module access point then and start operational approach, the OBJ1 as a result that returns gives the flow process Cell processor, judge the attribute of OBJ1 according to corresponding data feedback method, then the HTTP request is redirected to specified page, the realization that is redirected to specific page is by returning corresponding redirect sign in the data feedback interface in the flow process Cell processor, for example among Fig. 4, then return the case1 sign if will jump to p2.jsp, then return the case2 sign if will jump to p3.jsp.When the user after the p2.jsp submission form, process is similar to the above, after the workflow management module finds corresponding flow process unit, the data transfer device that calls its flow process Cell processor is converted to MAP and OBJ1 array with the data among the HTTP and gives corresponding service module access point and handle, and the result that business module returns carries out the selection of page reorientation equally by the corresponding method of flow process Cell processor.
In implementing operation flow process shown in Figure 4, foreground developer's work separates fully with backstage developer's work, the foreground developer only needs to carry out corresponding data-switching according to summary design, and need not be concerned about and call and how to call which business module.Carry out the flow process assembling by procedure configuration files at last.
