jbpm4.3常用操作
?
//得到流程定义
List<ProcessDefinition> pdL = repositoryService.createProcessDefinitionQuery().list();
//流程实例
List<ProcessInstance> piL = executionService.createProcessInstanceQuery().list();
//当前用户的任务列表
List<Task> tL = taskService.findGroupTasks(username);
List<Task> tLByPerson = taskService.findPersonalTasks(username);
?
1、执行流程
?? 根据类ProcessInstance的属性ID，执行流程
???String pid = processInstance.getId();
?? executionService.signalExecutionById(pid);
?? //获取指定节点的Execution
?
?? Execution?exec?=?processInstance.findActiveExecutionIn(??}??
??else {??
????? for (String name: activityNames) {??
????? System.out.println("activity name is "+name);???
??????}??
??}
?
1、设置添加变量
executionService.setVariable(pid, "content","task2");
?
? Map<String, Object> variables = new HashMap<String, Object>();
? variables.put("result", "ok");
? taskService.setVariables(task.getId(), variables);
?
１、获取变量
Set<String> variableNames = taskService.getVariableNames(taskDbid);
Map<String, Object> variables = taskService.getVariables(taskDbid, variableNames);
?

2、查找所有任务
List<Task> ts = jbpmTemplate.getTaskService().createTaskQuery().list();
???? for(Task t : ts){
???? ?if(t.getName().equals("task1")){
???????jbpmTemplate.completeTask(t.getId());//通过任务id让任务向下流转
?? Map map = HashMap();
??????? map.put("day",day);
jbpmTemplate.getTaskService().completeTask(t.getId(),map);//可以传参数
??}
?
?
3、通过任务ID取指定变量的值
String leaveId = (String) jbpmTemplate.getVariableByTaskId(taskId, "leaveId");
String leaveId = (String) taskService.getVariable(taskId, "leaveId");
? //通过流程实例id取指定变量的值
? String pid = processInstance.getId();
??String answer = (String) executionService.getVariable(pid, "answer");
?
４、判断流程是否执行在某个节点
processInstance.isActive("submit document")；
?
５、任务转交
1.设置candidate-groups="lingo"
2.lingo可以通过findGroupsTasks()看到共享任务
3.使用assignTask(taskid, "admin")将这个任务转交给admin
4.admin通过findPersonalTasks()看到待办任务
5.admin通过completeTask()完成任务。
如果按照上面的步骤，jbpm-4.3下测试是通过的，下面是测试代码：
??????? ProcessInstance processInstance = executionService
??????????? .startProcessInstanceByKey("X0603CandidateGroupTest");
??????? List<Task> taskList = taskService.findGroupTasks("lingo");
??????? assertEquals(1, taskList.size());
??????? Task task = taskList.get(0);
??????? taskService.assignTask(task.getId(), "admin");
??????? taskList = taskService.findPersonalTasks("admin");
??????? assertEquals(1, taskList.size());
??????? taskService.completeTask(task.getId());
?
6、多条件判断
? expr="#{a == 1 && b == 1}"
?
7、获取一个流程中的个人任务
public void assign(Assignable assignable, OpenExecution execution) { TaskImpl taskImpl = (TaskImpl)assignable; ExecutionImpl executionImpl = (ExecutionImpl)execution;}?
