一、概要
- 設計TASK的表主要是:ACT_RU_TASK,ACT_HI_TASKINST(見參考-activiti表);
- 任務主要有:人工任務(usertask),服務任務(servicetask)等;
- 候選人/候選組(candidate):可以執行任務的一類人或者多個組,候選人/候選組中都可以去簽收任務,一旦某人簽收,就成為受理人,其他人就不能再簽收受理此任務;usertask流程圖中,candidate標示候選;候選人涉及的表ACT_RU_IDENTITYLINK;
- 受理人(assignee):有兩種情況,一種是候選人/組中有人簽收任務后成為受理人,另外一種是流程圖中直接指定受理人,但是可以指定一個動態受理人;受理人涉及的表ACT_RU_TASK;
- 持有人(owner):持有人設置主要是存入歷史表中,用於歷史任務的查詢,涉及的表ACT_HI_TASKINST;
二、任務操作
- 創建TASK任務與設置權限:可以使用代碼創建任務,但是實際操作中都是繪制流程圖。繪制TASK后,在屬性可以設置候選人和受理人,一般都是設置候選人,因為固定受理人不太符合程序變動;
候選人設置了deptleader,該值將部署在表ACT_RU_IDENTITYLINK中,查看xml看見:
//設置了候選組 <userTask id="deptLeaderAudit" name="部門領導審批" activiti:candidateGroups="deptLeader"> </userTask>

2.查詢候選任務
//根據候選組ID查詢擁有任務 List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup(groupA.getId()).list(); for (Task task : tasks){
System.out.println(task.getName());
} //根據用戶ID查詢任務 tasks = taskService.createTaskQuery().taskCandidateUser(user.getId()).list(); for (Task task : tasks){
System.out.println(task.getName());
} //調用taskCandidateGroupIn List<String> groupIds = new ArrayList<String>(); groupIds.add(groupA.getId()); groupIds.add(groupB.getId());
tasks = taskService.createTaskQuery().taskCandidateGroupIn(groupIds).list(); for (Task task : tasks){
System.out.println(task.getName());
} //查詢權限數據 List<IdentityLink> links = taskService.getIdentityLinksForTask(tasks.get(0).getId()); System.out.println("關系數據量: " + links.size());}
