Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the task list exhibiting method that the embodiment of the invention provides may further comprise the steps:
S101: when a flow instance operation, business processing logic is set to workflow table extended field corresponding service data in the context data of workflow engine by calling the interface of workflow engine, triggers the realization link redirect;
Wherein, described workflow engine generally is used for resolving the flow process of the definition in Workflow Management System, generates and safeguard flow instance, and the driving flow process runs to next link forward, and the generation mission bit stream, and task list represented on the interface etc.
In the flow instance, can comprise a plurality of link examples usually, the link example of artificial link can produce accordingly and delegate duties.Relation between each link can have multiple according to predefined logic determines logic, may be serial, also may walk abreast, and also may produce branch, promptly may form different paths by different links.Therefore, when workflow engine runs to next link forward in the driving flow process, may need to use concrete business datum, judge according to concrete business datum next which link needs run to.
For example, in the flow process of asking for leave, may have such situation in the flow instance: the fate of asking for leave is that the Times departmental manager examines below 10 days; The fate of asking for leave is that the Times personnel manager examines more than 10 days.At this moment, when carrying out certain flow instance, business processing logic just need be set to this business datum of fate of asking for leave in the context data of workflow engine by the interface of workflow engine, and workflow engine comes the normal redirect of realization link according to the concrete fate of asking for leave.
In the embodiment of the invention, at first need the business datum that each requirements of process in the system represents in task list is summarized, list the field that need represent, in the workflow table, expand the business datum that need represent.
Wherein, described workflow table can be flow instance information table or link example information table, that is to say, can expand the flow instance information table, also can expand the link information tabulation.The business datum that all flow processs are required all expands in the workflow table, and workflow engine adds business datum to corresponding extended field and gets final product when carrying out flow instance.
But, because the title of the business datum that needs in each flow process may be explained and differ, for example, in the flow process of asking for leave, need to represent " asking the dummy " this field, and in the loaning bill flow process, need to represent " borrower " this field, at this moment, if in the workflow table, expand " asking the dummy " and " borrower " field respectively, will make that in the task list of flow process of asking for leave " borrower " field is empty, in the task list of loaning bill flow process, " asking the dummy " field is for empty; Be to have a lot of otiose fields in the task list, and need in the workflow table, expand very many fields, make that the scale of workflow table is very big.
For this reason, can also carry out abstractly, obtain needing the field of expansion each field that need represent.For example, can " ask the dummy " reaching " borrower " abstract is " applicant ", increases " applicant " this extended field in the workflow table.Like this, in the flow process of asking for leave, the corresponding service data can be saved in " applicant " field " to ask the dummy ", in the loaning bill flow process, " borrower " corresponding service data also can be saved in " applicant " field, like this, can reduce the scale of workflow table effectively, in the task list that generates for idiographic flow, also can not have unnecessary field.
S102: workflow engine obtains the expanded configuration information of described workflow table extended field;
After determining to need the field of expansion, also need in configuration file, dispose the information of extended field, the title of the gauge outfit that these expanded configuration information comprise the title of extended field, represent in corresponding field, the task list and pattern etc. in the workflow list structure.Workflow engine can obtain expanded configuration information from described configuration file, and carries out the preservation of business datum according to the information of these configuration extended fields.
Wherein, the title of the gauge outfit that represents in the task list is exactly the title that finally is presented in the gauge outfit in the task list, and the title of the field of expanding in this title and the workflow table can be inequality.Why want the title of the gauge outfit that represents in the configuration task list, be because, the row name in the database is that the form with English exists, therefore, during extended field, the row name of extended field also is English in the workflow table; For the ease of checking, can be in the extended field configuration information, the gauge outfit title of the field that represents in the configuration task list, for example, the gauge outfit title of extended field can be configured to database in the corresponding Chinese of row name, be convenient to Chinese user like this and check task list.
Determine the good field that needs expansion, and finishing after the configuration of extended field information, just can add extended field in the workflow table in Workflow Management System.The above is determined extended field, disposes expanded configuration information in configuration file, add extended field in the workflow table is preliminary preparation, finish the work after the expansion of stream table, but just in the process of each process flow operation, the business datum that need represent in task list is kept in the database in the corresponding extended field of workflow table.
S103: workflow engine obtains the value of each extended field corresponding service data according to described expanded configuration information from described context data, and the value of described each extended field corresponding service data is saved in the extended field corresponding in the workflow table;
Therefore, final in database the table of Workflow Management System, not only comprise the data of workflow inside, also comprise the business datum that need in task list represent relevant with workflow instance.When the needs showing task list, only need that these workflow tables of flow instance information table, link example table and work distribution chart are carried out correlation inquiry and get final product, and need not carry out correlation inquiry with the business datum table again.
S104: when workflow engine receives the request of showing task list of client, dynamic queries database, and the representing of the tabulation of finishing the work.
After executing flow instance, the user just can login Workflow Management System and check the task list of oneself.In the embodiment of the invention, workflow engine can also receive the request of the showing task list of client, the dynamic queries database, and finish the work the tabulation represent.
In the prior art, during showing task list, a plurality of workflow tables and business datum table need be carried out correlation inquiry, but because dissimilar flow definitions needs related different business datum table, therefore, system has no idea to inquire about the data that obtain task list with a unified SQL, need use different SQL to different flow definitions.
And in the embodiment of the invention because by the workflow table is expanded, business datum is kept in the extended field of workflow table, do not need workflow table and business datum table are carried out correlation inquiry, therefore, just can adopt the unified query logic SQL of dynamic organization to inquire about, obtain the data of task list.Concrete, can write the SQL that inquiry is used in advance, in the process of using SQL to inquire about, can discern extended field automatically, and obtain business datum wherein, therefore, need not use different SQL at different flow processs.
Wherein, describedly utilize unified query logic dynamic organization SQL query database, and the specific implementation that represents of the tabulation of finishing the work can be: obtain the expanded configuration information of task list, and according to the field name in the described expanded configuration information, the query SQL of dynamic organization's task list data; Utilize described query SQL Query Database, obtain the value of each field; The task list that represents described generation according to the expanded configuration information that presets.Specifically when representing the task list of described generation according to the expanded configuration information that presets, can and represent pattern according to the name of the gauge outfit of the extended field correspondence in the expanded configuration information, organize the presenting information that finally turns back to client, and these information are turned back to client; Client just can be at showing task list on the interface accordingly after the information that obtains to return.
To sum up, the primary clustering that relates in the method that the embodiment of the invention provides and dealing with relationship as shown in Figure 2 is described below: the developer is saved in the information of task list expansion in the configuration file; When service logic advances flow process at the interface that calls workflow engine, the value of extended field corresponding service data is set in the engine context, workflow engine is handled the preservation extend information automatically according to configuration information.Initiate to obtain the request of task list to workflow engine when the task list client, workflow engine is assembled SQL automatically according to configuration, from database, obtain the data result collection, process to the end demonstrating data and return to client according to the presenting information of configuration and represent.
As seen, in the method for the showing task list that the embodiment of the invention provides, workflow table and business datum table need not be carried out correlation inquiry, the business datum that need represent in task list can directly be kept in the workflow table by workflow engine, therefore, can improve the efficient of showing task list.
