三、控制层Controller
初始化流程的DTO
package com.awifi.capacity.project.manager.activiti.provider.bean.dto; import lombok.Data; /** * @ClassName InitiationProcessDTO * @Description TODO * @Author 张鑫 * @Date 2022/5/25 * @Version 1.0 **/ @Data public class InitiationProcessDTO extends TaskApprovalDTO{ String applicantUser; String reviewerUser; String processInstanceId; String processType; String deleteReason; }
任务审核DTO
package com.awifi.capacity.project.manager.activiti.provider.bean.dto; import lombok.Data; import java.util.HashMap; /** * @ClassName TaskApprovalDTO * @Description TODO * @Author 张鑫 * @Date 2022/5/25 * @Version 1.0 **/ @Data public class TaskApprovalDTO { String taskId; String processInstanceId; String userName; String field = "isOk"; String isOk = "true"; String comment = "同意"; HashMap<String, Object> hashMap; }
控制层

return activitiService.taskListByInitiator(userName); } // 查询我未完成的流程 // 查询我完成的流程 }
四、实现类Service
4.1 流程启动（不进入下一环节）
@Override public String startProcess(InitiationProcessDTO initiationProcessDTO) { ResponseJson responseJson = new ResponseJson(); // 根据流程类型获取processFile String processFile = EnumProcess.getEnumText(initiationProcessDTO.getProcessType()); if (processFile == null) { throw new UserAuthException(EnumCode.ACTICITI_PROCESSTYPE_ISWORRY.getCode(), EnumCode.ACTICITI_PROCESSTYPE_ISWORRY.getText()); } // 生成businessKey String businessKey = IDGenerator.getID(); identityService.setAuthenticatedUserId(initiationProcessDTO.getApplicantUser()); // 申请人写入 Map<String, Object> map = new HashMap<>(); map.put("applicantUser", initiationProcessDTO.getApplicantUser()); map.put("reviewerUser", initiationProcessDTO.getReviewerUser()); // 流程启动 ProcessInstance processInstance = ActivitiManager.startProcess(processFile, initiationProcessDTO.getProcessType(), activitiDeployMapper, businessKey, map); responseJson.setData(processInstance.getProcessInstanceId()); return JSON.toJSONString(responseJson); }
4.2 流程启动（直接进入下一环节）
@Override public String startProcessTo(InitiationProcessDTO initiationProcessDTO) { ResponseJson responseJson = new ResponseJson(); // 根据流程类型获取processFile String processFile = EnumProcess.getEnumText(initiationProcessDTO.getProcessType()); if (processFile == null) { throw new UserAuthException(EnumCode.ACTICITI_PROCESSTYPE_ISWORRY.getCode(), EnumCode.ACTICITI_PROCESSTYPE_ISWORRY.getText()); } // 生成businessKey String businessKey = IDGenerator.getID(); // 申请人写入 Map<String, Object> map = new HashMap<>(); map.put("applicantUser", initiationProcessDTO.getApplicantUser()); map.put("reviewerUser", initiationProcessDTO.getReviewerUser()); identityService.setAuthenticatedUserId(initiationProcessDTO.getApplicantUser()); // 流程启动 ProcessInstance processInstance = ActivitiManager.startProcess(processFile, initiationProcessDTO.getProcessType(), activitiDeployMapper, businessKey, map); Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult(); taskService.complete(task.getId()); // 开启后，环节会走到发起请假请求，要完成这个环节，才能到下一个审核环节 responseJson.setData(processInstance.getProcessInstanceId()); return JSON.toJSONString(responseJson); }
4.3 审批任务
@Override public String approvalTask(TaskApprovalDTO taskApprovalDTO) { String user = taskApprovalDTO.getUserName(); String isOk = taskApprovalDTO.getIsOk(); //先查历史表 判断流程是否存在 HistoricProcessInstance historicProcessInstance =historyService.createHistoricProcessInstanceQuery().processInstanceId(taskApprovalDTO.getProcessInstanceId()).singleResult(); if(Objects.isNull(historicProcessInstance)) { throw new UserAuthException(EnumCode.ACTICITI_PROCESS_ISEXSIT.getCode(), EnumCode.ACTICITI_PROCESS_ISEXSIT.getText()); } Task task = taskService.createTaskQuery().processInstanceId(taskApprovalDTO.getProcessInstanceId()).taskCandidateOrAssigned(user).singleResult(); // 判断任务是否存在 if (Objects.isNull(task)) { throw new UserAuthException(EnumCode.ACTICITI_TASK_IS_NOTFOUND.getCode(), EnumCode.ACTICITI_TASK_IS_NOTFOUND.getText()); } // 进行签收 taskService.claim(task.getId(), user); //增加审批备注 taskService.addComment(task.getId(), task.getProcessInstanceId(), taskApprovalDTO.getComment()); //设置本地参数。在myListener1监听中获取。防止审核通过进行驳回 taskService.setVariableLocal(task.getId(), taskApprovalDTO.getField(), isOk); // 传入变量 Map<String, Object> map = new HashMap<>(); map.put(taskApprovalDTO.getField(), taskApprovalDTO.getIsOk()); taskService.complete(task.getId(), map); TaskVO taskVO = BeanUtil.copyProperties(task, TaskVO.class); taskVO.setTaskId(task.getId()); taskVO.setProcessInstanceId(taskApprovalDTO.getProcessInstanceId()); taskVO.setProcessInstanceName(historicProcessInstance.getProcessDefinitionName()); taskVO.setTaskName(task.getName()); // 查询流程信息（返回流程状态） ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(taskApprovalDTO.getProcessInstanceId()).singleResult(); if (processInstance != null) { taskVO.processInstanceIsEnd(processInstance.isEnded()); } else { taskVO.processInstanceIsEnd(true); taskVO.setEndTime(historicProcessInstance.getEndTime()); } ResponseJson responseJson = new ResponseJson(); responseJson.setData(taskVO); return JSON.toJSONString(responseJson);
4.4 查询我发起的流程
@Override public String myProcess(String userName) { List<HistoricProcessInstance> list = historyService.createHistoricProcessInstanceQuery().startedBy(userName).list(); ResponseJson responseJson = new ResponseJson(); responseJson.setData(list); return JSON.toJSONString(responseJson); }
4.5 流程下任务详情
@Override public String processInfo(String processInstanceId) { List<HistoricTaskInstance> list = historyService.createHistoricTaskInstanceQuery().processInstanceId(processInstanceId).list(); ResponseJson responseJson = new ResponseJson(); responseJson.setData(list); return JSON.toJSONString(responseJson); }
4.6 删除流程
@Override public String deleteProcess(InitiationProcessDTO deleteProcessDto) { try { runtimeService.deleteProcessInstance(deleteProcessDto.getProcessInstanceId(),deleteProcessDto.getDeleteReason()); } catch (Exception e) { throw new UserAuthException(EnumCode.ACTICITI_DELETEPROCESS_ISWORRY.getCode(),EnumCode.ACTICITI_DELETEPROCESS_ISWORRY.getText()); } ResponseJson responseJson = new ResponseJson(); responseJson.setData("OK"); return JSON.toJSONString(responseJson); }
4.7 我待审核的任务
@Override public String taskCandidateIsMe(String userName) { ResponseJson responseJson = new ResponseJson(); List<TaskVO> taskVOS = new ArrayList<>(); List<Task> tasks = taskService//与任务相关的Service .createTaskQuery()//创建一个任务查询对象 .taskCandidateOrAssigned(userName) .list(); if(tasks !=null && tasks.size()>0){ for(Task task:tasks){ ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId(task.getProcessInstanceId()).singleResult(); TaskVO taskVO = BeanUtil.copyProperties(task, TaskVO.class); taskVO.setApplicantUser(processInstance.getStartUserId()); taskVO.setProcessInstanceName(processInstance.getProcessDefinitionName()); taskVO.setTaskId(task.getId()); taskVO.setTaskName(task.getName()); taskVO.processInstanceIsEnd(processInstance.isEnded()); taskVOS.add(taskVO); } } responseJson.setData(taskVOS); return JSON.toJSONString(responseJson); }
五、监听器
package com.awifi.capacity.project.manager.activiti.provider.listener; import org.activiti.engine.ProcessEngine; import org.activiti.engine.ProcessEngines; import org.activiti.engine.delegate.DelegateExecution; import org.activiti.engine.delegate.ExecutionListener; import org.activiti.engine.history.HistoricTaskInstance; import org.activiti.engine.impl.persistence.entity.ExecutionEntity; import org.springframework.stereotype.Service; import org.springframework.util.ObjectUtils; import java.util.List; /** * @ClassName MyTaskListener * @Description TODO * @Author 张鑫 * @Date 2022/5/24 * @Version 1.0 **/ @Service public class MyTaskListener implements ExecutionListener { @Override public void notify(DelegateExecution execution) { ProcessEngine services = ProcessEngines.getDefaultProcessEngine(); ExecutionEntity entity = (ExecutionEntity) execution; String processInstId = entity.getProcessInstanceId(); //流程实例Id //根据审批传入的参数判断是否打回 Object value = execution.getVariableInstance("isOk").getValue(); if (ObjectUtils.isEmpty(value)) { value = execution.getParent().getVariableInstance("isOk").getValue(); } ; if (!ObjectUtils.isEmpty(value) && "true".equals(value)) { return; } List<HistoricTaskInstance> list = services.getHistoryService().createHistoricTaskInstanceQuery().orderByTaskCreateTime().asc() .processInstanceId(processInstId) .list(); if (list != null) { String user = list.get(0).getAssignee(); //获取最新的一个责任人信息回退给他 execution.setVariable("applicantUser", user); } } }
