1, design logistics distribution process
2. Start the logistics distribution process
3. Query Group task, pick Group task
4. Query personal tasks and personal tasks
1. Design the logistics distribution process Logistics and distribution process
Task assignment based on group tasks, using exclusive gateways, branching selection using process variable implementations
Activiti Graphical Interface:
The ID value of the process corresponds to the key value in the flow definition table and can be used to start the latest version of the process instance
In the Task node:
The general ID value corresponds to the Task_def_key value in the task table that defines the method name for the task in Taskaction in the project Taskdefinitionkey
The value of the candidate Grops property of the Main config corresponds to the name of the roles role, the ID value of group in the Activiti table (role and group synchronization are saved when the value of the group Id should be set to the name of role, Because the ID value is UUID is not easy to read)
Exclusive gateway, branch selection using process variable implementation, condition expression in condition gets the value in the process variable to determine true or false to select Branch
2. Start the process delivery processStep One: Provide a list method in the work order Management workordermanageaction to query a work order with a start status of "0"
Service Code:
Public list<workordermanage> Findlistnotstart () {Detachedcriteria Detachedcriteria = DetachedCriteria.forClass (workordermanage.class);//Add condition: Start = = 0detachedcriteria.add (Restrictions.eq ("Start", "0"); return Workordermanagedao.findbycondition (Detachedcriteria);}Step two : Configure Struts.xml
Step three : Provide startranster.jsp page, show work order
Fourth Step : Start the Logistics delivery process by providing the Start method in the Work Order management action
Service Code:
Get the Workordermanage object by ID set start status to 1 start state, and start the logistics delivery process instance
@Resourceprivate processengine processengine;//Start the logistics distribution process, set the work order object to the process variable public void start (String id) {Workordermanage Workordermanage = Workordermanagedao.findbyid (ID); Workordermanage.setstart ("1"); String Processdefinitionkey = "transfer";//Logistics distribution process keymap<string, object> variables = new hashmap<string, Object > Variables.put ("Business Data", Workordermanage);p Rocessengine.getruntimeservice (). Startprocessinstancebykey ( Processdefinitionkey, variables);}First step : Create a taskaction, provide findgrouptask, query the group (public) task of the currently logged on user
@Controller @scope ("prototype") public class Taskaction extends Actionsupport {@Resourceprivate processengine processengine;/** * Query Group task */public String Findgrouptask () {//task query Taskquery query = Processengine.gettaskservice (). Createtaskquery (); String Candidateuser = Boscontext.getloginuser (). GetId ();//filter Query.taskcandidateuser (Candidateuser) according to group task; Query.orderbytaskcreatetime (). DESC (); list<task> list = Query.list (); Actioncontext.getcontext (). Getvaluestack (). Set ("List", list); return "Grouptasklist";}Step two : Configure Struts.xml
Step three : grouptask.jsp page display Group task data
<body class= "Easyui-layout" ><div data-options= "region: ' Center '" ><table class= "Easyui-datagrid" fit= "True" nowrap= "false" ><thead><tr><th data-options= "field: ' ID ', width:120" > Task number </th> <th data-options= "field: ' Name ', width:120" > Task Name </th><th data-options= "field: ' Data ', width:520" > Business Data </th><th data-options= "field: ' Pick ', width:120" > Pickup task </th></tr></thead>< Script type= "Text/javascript" >function showData (taskId) {$.post ("${pagecontext.request.contextpath}/taskaction _showdata.action ", {" TaskId ": taskid},function (data) {$ (" #div "+taskid). HTML (data);});} function Toggledata (taskId) {$ ("#div" +taskid). Toggle (); </script><tbody><s:iterator value= "list" var= "task" ><tr><td><s:property value= " ID "/> </td><td><s:property value=" name "/></td><td><a onclick=" ToggleData (' ${ ID} ') "class=" Easyui-linkbutton "> View business Data </a><div style=" Display:none "id="Div${id}" ><script type= "Text/javascript" >showdata (' ${id} ');</script></div></td>< Td><s:a action= "Taskaction_taketask" namespace= "/" cssclass= "Easyui-linkbutton" > Pick <s:param name= " TaskId "value=" id "></s:param></s:a></td></tr></s:iterator></tbody></ Table></div></body>
Fourth Step : Provide the ShowData method in Taskaction, query the process variables according to the task ID
Receive task Idprivate string Taskid;public string GetTaskID () {return taskId;} public void Settaskid (String taskId) {this.taskid = taskId;} /** * AJAX Query Process variables * * @throws ioexception */public String showData () throws IOException {map<string, object> Map = Processengine.gettaskservice (). Getvariables (TaskId); Servletactioncontext.getresponse (). setContentType ("Text/html;charset=utf-8"); Servletactioncontext.getresponse (). Getwriter (). print (map); return NONE;}Effect:
Toggle () [If the element is visible, toggle to hidden, or if the element is hidden, toggle to visible. ] Control Div's style= "Display:none"
4. Pick Group TasksFirst step : Provide a method for picking group tasks in Taskaction Taketask
/** * Pickup Group Task */public String Taketask () {Processengine.gettaskservice (). Claim (Taskid,boscontext.getloginuser (). GetId ( ); return "Togrouptasklist";}Step two : Configure Struts.xml
5. Querying Personal tasksFirst step : Provide Findpersonaltask method in Taskaction, query personal task
The value of assignee depends on the synchronization setting of the USER_ID value Activiti when the user table synchronizes
/** * Query The current login's personal task */public String findpersonaltask () {taskquery query = Processengine.gettaskservice (). createtaskquery (); Query.taskassignee (Boscontext.getloginuser (). GetId ()); Query.orderbytaskcreatetime (). DESC (); list<task> list = Query.list (); Actioncontext.getcontext (). Getvaluestack (). Set ("List", list); return "Personaltasklist";}Step two : Configure Struts.xml
Step three : Provide personaltask.jsp
<body class= "Easyui-layout" ><div data-options= "region: ' Center '" ><table class= "Easyui-datagrid" fit= "True" nowrap= "false" ><thead><tr><th data-options= "field: ' ID ', width:120" > Task number </th> <th data-options= "field: ' Name ', width:120" > Task Name </th><th data-options= "field: ' Data ', width:520" > Business Data </th><th data-options= "field: ' Pick ', width:120" > Handling Tasks </th></tr></thead>< Script type= "Text/javascript" >function showData (taskId) {$.post ("${pagecontext.request.contextpath}/taskaction _showdata.action ", {" TaskId ": taskid},function (data) {$ (" #div "+taskid). HTML (data);});} function Toggledata (taskId) {$ ("#div" +taskid). Toggle (); </script><tbody><s:iterator value= "list" var= "task" ><tr><td><s:property value= " ID "/> </td><td><s:property value=" name "/></td><td><a onclick=" ToggleData (' ${ ID} ') "class=" Easyui-linkbutton "> View business Data </a><div style=" Display:none "id="Div${id}" ><script type= "Text/javascript" >showdata (' ${id} ');</script></div></td>< Td><s:a action= "Taskaction_%{taskdefinitionkey}" namespace= "/" cssclass= "Easyui-linkbutton" > Handling Tasks <s: param name= "taskId" value= "id" ></s:param></s:a></td></tr></s:iterator></ Tbody></table></div></body>
6.1 Handling the Audit work order task
The first step: to provide a way to handle the audit work order in Taskaction
Private integer check;//audit result public integer Getcheck () {return check;} public void SetCheck (Integer check) {this.check = check;} @Resourceprivate Iworkordermanageservice workordermanageservice;/** * For the Audit work Order task */public String checkworkordermanage ( {if (check = = null) {//Jump to audit Work order Form page//query process variable map<string based on task ID, object> map = Processengine.gettaskservice (). Getv Ariables (TASKID); Actioncontext.getcontext (). Getvaluestack (). Set ("Map", map); return "Checkui";} else {//2, modify the Managercheck in the work order to "1" workordermanage workordermanage = (workordermanage) processengine.gettaskservice () . getvariable (TaskId, "Business Data"); Workordermanage.setmanagercheck ("1");//3, if the audit does not pass, modify the work order start to "0" if (check = = 0) { Workordermanage.setstart ("0");} Workordermanageservice.update (workordermanage);//1, Task ID according to task, set process variable checkmap<string, object> variables = new Hashmap<string, object> (); Variables.put ("Check", check);p Rocessengine.gettaskservice (). Complete (TaskId, variables); return "Topersonaltasklist";}}
Step two : Provide the check.jsp page as the form page for the review work order
<body>6.2 Handling Other tasks
Transact out library task public String Outstore () {map<string, object> variables = new hashmap<string, object> (); Variables.put ("Warehouse Administrator", Boscontext.getloginuser (). GetUserName ());p Rocessengine.gettaskservice (). Complete (TaskId, variables); return "Topersonaltasklist";} Handling distribution Tasks Public String Transfergoods () {map<string, object> variables = new hashmap<string, object> (); Variables.put ("PI", Boscontext.getloginuser () GetUserName ());p Rocessengine.gettaskservice (). Complete (TaskId, variables); return "Topersonaltasklist";} Sign-off task public String receive () {map<string, object> variables = new hashmap<string, object> (); Variables.put ("PI", Boscontext.getloginuser () GetUserName ());p Rocessengine.gettaskservice (). Complete (TaskId, variables); return "Topersonaltasklist";}
