Embodiment
Below in conjunction with accompanying drawing and embodiments of the invention, Java workflow development system and the method thereof based on workflow GPD of the present invention is described in further detail.
Basic thought of the present invention is: the present invention is conceived to the intensive feature of artificial node of domestic Workflow system, on the basis of the GPD of original development process file plug-in unit, carry out Optimization & realization, reduce workflow development cost, improve system granular, for developer's Efficient Development Workflow system provides support.
For the characteristics of demand of domestic Workflow system, the present invention proposes the workflow development system based on workflow visualization toolkit (GPD), from human task node, graphical navigation demand, component base resource, list visual and binding, engineering one key dispose five aspects for workflow development system, be optimized and realize.This system towards user object be enterprise-level Workflow system developer.The object of this system is to realize visual customization and the design of enterprise-level workflow, and issue workflow, carries out the user management of workflow, Admin Administration, the binding in respective members storehouse and management.Greatly shorten construction cycle and convenient management, realize random placement.
Fig. 1 is the scene schematic diagram of Java workflow development system of the present invention, and Fig. 2 is the system architecture diagram of Java workflow development system of the present invention.As shown in Figure 1 and Figure 2, described Java workflow development system, be divided into five essential parts, operate the visual and binding module of visualized graphs navigational tool module, enterprise customer organize models visualization view module, Reusable Components storehouse views module, list, engineering one key is disposed functional module.Wherein,
The first, described operation visualized graphs navigational tool module.In the process of investigation stage development process engineering, accumulated feature and the defect of many use GPD.Such as needing a lot of jar bag copies and the modification of configuration file after a newly-built dynamic web engineering, binding Java node need to be modified etc. to source code, for these aspects, this system corresponding to dynamic web engineering development, deployment, test development corresponding navigation feature.This system has been carried out visual navigation to the parameter of Java node.The visualized graphs navigation that these have all realized developer, facilitates developer's deployment test greatly.The gordian technique of this part comprises: Eclipse developing plug technology, realizes navigation and need to inherit and cover the new function of increase the navigation of dynamic web engineering.For the parameter setting of Java node, need to use SWT graph technology to realize.
The second, enterprise customer organize models visualization view module.System is originally undertaken by code way of realization in processed group organization model, namely developer need to call relevant interface and carries out the modeling work of organize models in the code of backstage, and effect is in system database, to have inserted organize models's information.This aims of systems is the work process flow design tool of enterprise-level, and in enterprise, the modeling of organize models is absolutely necessary, and role's position of personnel all needs a unified development environment to go allotment.Be directed to this, the research of organize models's modeling tool is just quite necessary.In native system, added organize models's modeling view, object is to make developer to carry out visually easily the modeling work of organize models, can distribute visually human task to corresponding personnel simultaneously.Correspond to GPD workflow development instrument, the realization of organize models's modeling tool is in original Eclipse inserter tool, to have increased a view.View need to guarantee that model still exists when opening development environment for the second time, but the plug-in unit pattern of Eclipse is not supported this situation, secondly, organize models need to be written in database, could be used by flow engine, be that organize models needs directly to carry out with database the transmission of information, moreover, in order to facilitate the portability of the model that developer develops, being about to organize models stores, the organize models editting before can using in other development environment, has adopted the storage mode of XML file.Realize the view that organize models's modeling view mainly need to add organize models in Eclipse environment, then on the basis of this view, carry out design and the realization of organize models.
The 3rd, Reusable Components storehouse views module.GPD flow scheme design instrument itself does not have the realization of component base part, but JBPM supports to EJB member directly calling in flow definition file, can expand on this basis the structure of component base.In some ripe workflow design instruments, the component base part that is absolutely necessary.Member is in esse replaceable part in system, and it realizes specific function, meets a set of interface standard and realizes a group interface.Member can be understood as a self-existent part, carries out specific service logic, is not subject to external interference, and only need to carry out calling of interface just can return to corresponding result, greatly reduces the degree of coupling for flow scheme design.Based on research above, in the optimization of GPD, component base becomes an indispensable part.This system conventional member, for flow process developer, carry out, the member that this can multiplexingly exist developer, has reduced workload.Only the member of needs is loaded, pull, fill in parameter and just can use afterwards.In addition, consider that the component base providing can not meet the situation of real world applications, developer also can develop the member of oneself, joins in user-defined component base and uses.Low coupling and the high reusability of system have been considered fully.
The 4th, the visual and binding function module of list.In GPD development environment, during artificial node binding list, need to carry out the craft of source code to revise, in native system, this function carried out to the encapsulation of visualization interface, Form Designer environment is originally browser form, is integrated in Eclipse development environment in native system.During artificial node binding list, double-click, system provides visual list list, by developer, is selected, and the modification of source code is carried out on backstage.Facilitate developer to carry out the design function of list.
The 5th, engineering one key is disposed functional module.Then this functional module, for not convenient in performance history, after engineering development is complete, only need to be selected to dispose at engineering right button, and the network address of server is provided by developer afterwards, then carries out packing and the deployment of engineering.
In this system architecture diagram as shown in Figure 2, five major parts can clearly finding out that this system comprises and workflow editor part originally.Because five major parts of this system are relatively independent, be therefore described respectively, the present invention is described in further detail.
1) operation visualized graphs navigational tool module.
Fig. 3 is the process flow diagram of operation visualized graphs navigational tool module.The step of required execution in the process of new construction has been described, in former GPD environment, new construction need to copy configuration file, and opens and carry out manual configuration and write, and need to wrap accordingly to copy under engineering catalogue, while issuing for flow process, use.The navigation of operation visualized graphs provides the newly-built navigation of engineering easily, system for filling database and business datum library information in navigation procedure, and simple connecting test is provided, guarantee the correctness of the database information of input.When engineering is newly-built, database information can be written in configuration file, and need to carry out hand filling.In addition,, for the automatic operation node in workflow, Java node provides visual navigational tool, provide and fill in parameter, the Visualization Service of configuration Java node, in former GPD environment, these needs of work developer learns Java node association attributes, and revises source file support.In editing machine, for Java node, only need to double-click, just can eject the dialog box of corresponding configuration Java node file and parameter, the configuration that developer only need to carry out parameter in dialog box just can write information in the defined file of workflow automatically, and does not need the manual modification stream defined file that goes.
2) enterprise customer organize models visualization view module.
(1) be first the problem that imports and exports of organize models.View need to guarantee that model still exists when opening development environment (being Eclipse) for the second time, but the plug-in unit pattern of Eclipse is not supported this situation, secondly, organize models need to be written in database, could be used by flow engine, be that organize models needs directly to carry out with database the transmission of information, moreover, in order to facilitate the portability of the model that developer develops, being about to organize models stores, the organize models editting before can using in other development environment, has adopted the storage mode of XML file.In sum, the importing of organize models is divided into two parts, and one is the XML file having editted, and form need to meet the form defining; One is from engine database, and these two kinds of modes all should be organized model view and support.Corresponding with the importing of organize models, the derivation of organize models needs two kinds of modes, i.e. XML file and engine database equally.During XML file, facilitate information to store with document form, increase portable; Engine database is that the organize models in order to make editor can be identified by engine, thereby carries out correct human task distribution function, makes work process flow true(-)running.
(2) be secondly editor's problem of organize models.In organize models's modeling view, if just import information model from XML file or database merely, and then carry out human task and distribute accordingly, this has just lacked very large dirigibility, if need to revise organize models, can only from XML file or these two data sources of database, modify.This situation will increase developer's workload greatly, and the tabular form of XML document form and database table has determined the complicacy of this work, normally tree shape model of user group's model, has several points of tissues under certain tissue, under point tissue, has respectively again the situations such as certain user.Based on above reason, on organize models's view, increased the editting function to organize models.Need that some basic copy, this function such as stickup, newly-built, editor.
(3) be again the visualization problem that artificial node distributes.In flow scheme design device, the distribution of human task node is a simple text box, and developer needs the manual id that writes access customer or group, does not have visual figure to go to help developer to select.The meaning of setting up organize models is just graphical display organization model, makes developer carry out easily the distribution of human task, and this distribution can be assigned to group or individual by concrete task.Therefore need in the properties view of human task node, add corresponding information.For the inconvenience of manual input before improving, in the properties view of human task node, the position of corresponding text box has added a button, the function of clicking this button is just to show whole organize models, and developer can in organize models, carry out single choice easily or multiselect carries out the distribution of task.This realization is searched user identification and is freed from loaded down with trivial details organize models, and patterned interface is more conducive to user and finds out the relation of inclusion between organize models.
Fig. 4 is the scene schematic diagram of enterprise customer organize models visualization view module.As shown in Figure 4, the scene schematic diagram of organize models's MBM.In organize models, developer can be presented at the tree structure of organize models in organize models's view by XML document form or database form, for developer provides visual with reference to using, developer can carry out the corresponding editor of modification to organize models in view, organize models up-to-date in view can also be carried out afterwards to the preservation of XML document form or the preservation of database form.Be saved in system database is for flow engine is for the use of organize models.
Fig. 5 provides the User Exploitation instantiation procedure that organize models's MBM is concrete, in this process, for every kind of operation of user, has corresponding function support that service is provided.
3) Reusable Components storehouse views module.
First be research and the demand in component of a system storehouse.Component of a system storehouse be workflow tool itself with the list of member, flow process developer can load according to the concrete existing member of selective system that needs.After loading, can be considered as common JAVA node and be dragged in editing machine, carry out the selection of method, add corresponding parameter, thereby call in workflow.
Next is research and the demand of User Defined component base.Flow process developer's continuous needed member of accumulation in actual performance history, in order to make developer needn't carry out the work of some repetitions, this workflow tool provides a User Defined component base for these members.The member that developer develops can join these members in development environment by the function of adding, and can load by the method identical with component of a system storehouse, pulls, and fills in parameter.It should be noted that, developer must provide the interface of effective EJB member, such as the JNDI title of EJB member and the list of method, if there is mistake here, developing instrument does not detect the mistake here, thereby occurs mistake in the time of can causing this EJB member of process invocation.
The research of function of search again.Component base can increase along with the growth of developer's development time, and navigating to fast some members needs function of search.On component base view, realized this function, developer inputs key word, and component of a system storehouse and User Defined component base can filter out corresponding content according to the variation of key word content in real time, to facilitate developer to search use.
Fig. 6 provides the User Exploitation instantiation procedure of Reusable Components storehouse views module, developer can use the member in existing component of a system storehouse, the member that also oneself can be created on stream join in component base, carry out multiplexing, thereby reduce cost of development.Component base view also provides simple keyword search function, for developer, finds fast the member needing to load binding.
The loading binding of member is with common to automatically perform node (being Java node) similar, be loaded in editing machine, after being dragged to flow definition file, double-click, can eject the dialog box of configuration parameter, the configuration that developer only need to carry out relevant parameter in dialog box just can be written to parameter information in the source file of flow definition file and not need to open source file and write configuration by hand.
4) the visual and binding function module of list.
In GPD development environment, during artificial node binding list, need to carry out the craft of source code to revise, in native system, this function carried out to the encapsulation of visualization interface, Form Designer environment is originally browser form, is integrated in Eclipse development environment in native system.During artificial node binding list, double-click, system provides visual list list, by developer, is selected, and the modification of source code is carried out on backstage.Facilitate developer to carry out the design function of list.
5) engineering one key is disposed functional module.
Then this functional module, for not convenient in performance history, after engineering development is complete, only need to be selected to dispose at engineering right button, and the network address of server is provided by developer afterwards, then carries out packing and the deployment of engineering.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
