最近工作中有用到工作流的開發(fā)，引入了flowable工作流框架，在此記錄一下springboot整合flowable工作流框架的過程，以便后續(xù)再次使用到時可以做一些參考使用，如果項目中有涉及到流程審批的話，可以使用該框架幫我們實現(xiàn)流程圖示化展示的功能，為了快速了解flowable工作流框架的一個使用過程，我們直接步入主題，springboot整合flowable工作流框架的步驟如下：
1、首先創(chuàng)建一個springboot工程，然后引入flowable pom依賴，代碼如下：
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-spring-boot-starter</artifactId>
<version>6.7.0</version>
</dependency>2、創(chuàng)建流程圖定義文檔
這里有一個使用flowable-ui可視化的工程來創(chuàng)建流程圖定義文檔，https://www.wandouip.com/t5i212543/，具體實施過程如下：
先從 https://github.com/flowable/flowable-engine/releases 上下載一個發(fā)布文檔，這里選擇Flowable 6.7.2 release；然后解壓縮文件，將里面的wars文檔下的兩個jar包(flowable-rest.war、flowable-ui.war)部署到tomcat下，放到webapps文件加下，點擊運行，運行存在一個解壓縮文件的過程，會產(chǎn)生flowable-rest、flowable-ui文件夾，瀏覽器輸入 http://localhost:8080/flowable-ui，如下圖：
用戶名密碼輸入admin/test，如下圖：
點擊建模器應(yīng)用程序，點擊右上角”創(chuàng)建流程“，填寫相關(guān)信息，進(jìn)去后就可以可視化地創(chuàng)建流程，如下圖：
上面初步展示了使用可視化制作工具制作流程圖的過程，然后導(dǎo)出BPMN2文件，文件內(nèi)容大概如下：

</definitions>以上初步實現(xiàn)怎么使用可視化工具來創(chuàng)建流程圖定義文件，里面更為具體的使用方法還有待探索，上面的步驟執(zhí)行完畢后，我們就可以運行我們的springboot工程了，在配置文件中配置好數(shù)據(jù)庫鏈接相關(guān)的信息后，然后配置flowable相關(guān)信息：
flowable:
aysnc-executor-activate: false
database-schema-update: true
process-definition-location-prefix: classpath*:/processes/
process-definition-location-suffixes: "**.bpmn20.xml, **.bpmn"
上面的信息配置完畢后，就可以運行我們的工程了，在運行工程之前，在工程的resources文件夾下創(chuàng)建一個processes文件夾，我們的流程定義文檔就放在這個文件夾下，創(chuàng)建一個process-test.bpmn20.xml放到processes文件夾下，具體內(nèi)容定義如下：

@Slf4j
public class SendJuniorRejectionMailDelegate implements JavaDelegate {
@Override
public void execute(DelegateExecution execution) {
String requestUser = (String) execution.getVariable("requestUser");
String resourceId = (String) execution.getVariable("resourceId");
System.out.println("SendJuniorRejectionMailDelegate");
log.info("send approval success mail for user [" + requestUser + "] with apply resource [" + resourceId + "]");
}
}上面的類需要實現(xiàn)JavaDelegate這個接口，上面的內(nèi)容定義完畢后，就可以定義我們的實現(xiàn)方法了，先創(chuàng)建一個接口，定義一些方法：
public interface IProcess {
/**

* queryProcessVariables方法獲取到，調(diào)用時需要傳遞processInstanceId

* @return
*/
ProcessInstanceEntity startProcess(ParamObj paramObj);
/**
* 獲取指定工作人的代辦任務(wù)
* @param assignee
* @return
*/
List<TaskInstanceEntity> taskInstance(String assignee);
/**

* @param paramObj
*/
void handleTask(ParamObj paramObj);
/**

* @param processInstanceId
* @return
*/
List<ProcessStatusEntity> queryProcessStatus(String processInstanceId);
/**
* 查看創(chuàng)建流程實例時登記的變量信息
* @param processInstanceId
* @return
*/
Map<String,Object> queryProcessVariables(String processInstanceId);
/**

* @return
*/

/**

*/
void genProcessDiagram(HttpServletResponse httpServletResponse, String processInstanceId) throws Exception;
/**
* 查詢是否存在歷史數(shù)據(jù)的流程實例

*/
boolean isExistHistoricProcessInstance(String processInstanceId);
/**

* @param processInstanceId

*/
boolean isExistRunningProcessInstance(String processInstanceId);
/**

*/
void suspendProcessInstance(String processInstanceId);
/**

* @param paramObj
*/
void terminateProcessInstance(ParamObj paramObj);
/**

void activateProcessInstance(String processInstanceId);
/**

* @param paramObj
*/
void deleteProcessInstance(ParamObj paramObj);
/**

* @param targetTaskKey 返回到的目標(biāo)任務(wù)ID
*/
void rollbackTask(String taskId, String targetTaskKey);
boolean isProcessFinished(String processInstanceId);

}實現(xiàn)類中注入的變量都是flowable框架中的變量，實現(xiàn)類中的方法的作用在接口中都有向相關(guān)注釋，其中deleteProcessInstance方法中會引用一個類來刪除流程實例,DeleteFlowableProcessInstanceCmd類的定義如下：
@Data
public class DeleteProcessInstanceCmd implements Command<Void>, Serializable {
String processInstanceId;
String deleteReason;
//是否刪除歷史
boolean cascade=true;
public DeleteProcessInstanceCmd(){
}
public DeleteProcessInstanceCmd(String processInstanceId,String deleteReason){
this.deleteReason=deleteReason;
this.processInstanceId=processInstanceId;
}
public DeleteProcessInstanceCmd(String processInstanceId,
String deleteReason,
boolean cascade){
this.deleteReason=deleteReason;
this.processInstanceId=processInstanceId;
this.cascade=cascade;
}
@Override
public Void execute(CommandContext commandContext) {
ExecutionEntity entity= CommandContextUtil.getExecutionEntityManager(commandContext)
.findById(processInstanceId);
if(entity!=null){
if(entity.isDeleted()){
return null;
}
if(Flowable5Util.isFlowable5ProcessDefinitionId(commandContext,entity.getProcessDefinitionId())){
Flowable5CompatibilityHandler handler=Flowable5Util.getFlowable5CompatibilityHandler();
handler.deleteProcessInstance(processInstanceId,deleteReason);
}else{
CommandContextUtil.getExecutionEntityManager(commandContext).deleteProcessInstance(entity.getProcessInstanceId(),deleteReason,cascade);
}
}
return null;
}
}上述功能了類定義完畢后，就可以創(chuàng)建我們的controller類了，我們的controller類的定義如下：
@RestController
@RequestMapping("/flowableTest")
public class FlowableController {
@Autowired
IProcess process;
@PostMapping("/startProcess")
public ProcessInstanceEntity startProcess(@RequestBody ParamObj paramObj){
return process.startProcess(paramObj);
}
@GetMapping("/getTaskInstance/{assignee}")
public List<TaskInstanceEntity> taskInstance(@PathVariable("assignee") String assignee){
return process.taskInstance(assignee);
}
@PutMapping("/handleTask")
public String handleTask(@RequestBody ParamObj paramObj){
process.handleTask(paramObj);
return "success";
}
@GetMapping("/queryProcessStatus")
public List<ProcessStatusEntity> queryProcessStatus(String processInstanceId){
return process.queryProcessStatus(processInstanceId);
}
@GetMapping("/queryProcessVariables")
public Map<String, Object> queryProcessVariables(String processInstanceId){
return process.queryProcessVariables(processInstanceId);
}
@GetMapping("/queryHistoryProcess")
public List<HistanceInstanceEntity> queryHistoryProcess(String assignee){
return process.queryHistoryProcess(assignee);
}
@GetMapping("/genProcessDiagram")
public void genProcessDiagram(HttpServletResponse httpServletResponse,
String processInstanceId) throws Exception {
process.genProcessDiagram(httpServletResponse,processInstanceId);
}
@GetMapping("/isExistHistoricProcessInstance")
public boolean isExistHistoricProcessInstance(String processInstanceId){
return process.isExistHistoricProcessInstance(processInstanceId);
}
@GetMapping("/isProcessFinished")
public boolean isProcessFinished(String processInstanceId){
return process.isProcessFinished(processInstanceId);
}
@GetMapping("/isExistRunningProcessInstance")
public boolean isExistRunningProcessInstance(String processInstanceId){
return process.isExistRunningProcessInstance(processInstanceId);
}
@PutMapping("/suspendProcessInstance")
public String suspendProcessInstance(String processInstanceId){
process.suspendProcessInstance(processInstanceId);
return "流程 "+processInstanceId+" 已經(jīng)掛起";
}
@PutMapping("/terminateProcessInstance")
public String terminateProcessInstance(ParamObj paramObj){
process.terminateProcessInstance(paramObj);
return "流程 "+paramObj.getProcessInstanceId()+" 已經(jīng)終止";
}
@PutMapping("/activateProcessInstance")
public String activateProcessInstance(String processInstanceId) {
process.activateProcessInstance(processInstanceId);
return "流程 "+processInstanceId+" 已經(jīng)激活";
}
@PutMapping("/deleteProcessInstance")
public String deleteProcessInstance(ParamObj paramObj){
process.deleteProcessInstance(paramObj);
return "流程 "+paramObj.getProcessInstanceId()+" 已經(jīng)刪除";
}
@PutMapping("/rollback")
public String rollbackTask(String taskId, String targetTaskKey){
process.rollbackTask(taskId,targetTaskKey);
return "流程回退成功";
}
}試運行工程，運行工程后，系統(tǒng)會自動生成一些表單，是一些act_和flw_開頭的表單，如下，利用postman創(chuàng)建一個流程實例：
查看流程示例圖：
調(diào)用查看任務(wù)接口，可以查看某個人有哪些任務(wù)需要處理：
調(diào)用任務(wù)處理接口：
查看處理后的結(jié)果：
以上是flowable流程框架的簡單應(yīng)用，更為詳細(xì)的使用等待后續(xù)的挖掘......
