剩下的核心API
流程定義與流程執行個體
/**HistoryProcessInstance*/
@Test
public void HistoryProcessInstance() {
List<HistoricProcessInstance> datas = historyService.createHistoricProcessInstanceQuery()
.finished().list();
for (HistoricProcessInstance historicProcessInstance : datas) {
System.out.println("流程執行個體id: "+historicProcessInstance.getId());
System.out.println("部署id: "+historicProcessInstance.getDeploymentId());
System.out.println("結束event: "+historicProcessInstance.getEndActivityId());
System.out.println("流程名稱: "+historicProcessInstance.getName());
System.out.println("PROC_DEF_ID: "+historicProcessInstance.getProcessDefinitionId());
System.out.println("流程定義Key: "+historicProcessInstance.getProcessDefinitionKey());
System.out.println("流程定義名稱: "+historicProcessInstance.getProcessDefinitionName());
System.out.println("開始event: "+historicProcessInstance.getStartActivityId());
}
} 【其他HistoryService查詢類似】
【個人感覺在前端架構比較完善的今天幾乎不會去用這個，但是還是做一些小demo】

public void FormType(){

ProcessInstance pi = runtimeService.startProcessInstanceByKey("whatFk");
System.out.println(pi);

variables.put("age", "18");
Task task = taskService.createTaskQuery().deploymentId(dep.getId()).singleResult();
formService.submitTaskFormData(task.getId(), variables);
} 資料庫内以流程變量的形式存儲了内容【注意：此方式設定的流程變量均為taskID】
@Test
public void FormTypeRead(){
//75005為偷懶直接從資料庫内複制的流程
Task task = taskService.createTaskQuery().processInstanceId("75005").singleResult();
TaskFormData taskFormData = formService.getTaskFormData(task.getId());
List<FormProperty> formProperties = taskFormData.getFormProperties();
for (FormProperty formProperty : formProperties) {
System.out.println(formProperty.getId() + "，value=" + formProperty.getValue());
}
} 上方代碼在該task未執行時能夠擷取表單所有元素
【修改代碼流程檔案與form要一同部署】
@Test
public void FormType(){
Deployment dep = repositoryService.createDeployment()
.addClasspathResource("bpmn/form.bpmn")
.addClasspathResource("bpmn/completeForm.form")
.deploy();
ProcessInstance pi = runtimeService.startProcessInstanceByKey("whatFk");
HashMap<String, String> variables = new HashMap<>();
variables.put("userName", "潘天淼");
variables.put("age", "18");
Task task = taskService.createTaskQuery().deploymentId(dep.getId()).singleResult();
formService.submitTaskFormData(task.getId(), variables);
} 【測試結果】
@Test
public void OutFormTypeRead(){
System.out.println(formService.getRenderedTaskForm("105016")==null);
HashMap<String, String> variables = new HashMap<>();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Calendar ca = Calendar.getInstance();
String startDate = sdf.format(ca.getTime());
ca.add(Calendar.DAY_OF_MONTH, 2); // 目前日期加2天
String endDate = sdf.format(ca.getTime());
variables.put("startDate", startDate);
variables.put("endDate", endDate);
variables.put("reason", "公休");
formService.submitTaskFormData("105016", variables);
} 正常情況下呢這裡是可以擷取表單的。對于外置表單，隻是把表單内容都儲存在單獨的form檔案中，是以隻能通過讀取所有的請求參數作為流程啟動參數。
圖示部分為整塊HTML的内容【想些啥都OK我是複制了一段HTML帶表單的說】。
activiti 基礎部分到此就結束了。關于managementService據說是不怎麼用的到的，呐網上資源也比較少，就不去細說了。接下來的話。本周内會把BPMN2.0涉及到的元件全部過一遍【不常用的Task元件我就不講了。中間元件和補償邊界會全部涉及】。
