引入依赖，选择需要的依赖

编写demo
package com.example.giveup.service.serviceImpl; import com.example.giveup.service.ActivityConsumerService; import org.activiti.engine.*; import org.activiti.engine.impl.persistence.entity.ExecutionEntity; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.HashMap; import java.util.Map; @Service public class ActivityConsumerServiceImpl implements ActivityConsumerService { @Autowired private RuntimeService runtimeService; @Autowired private TaskService taskService; @Autowired private RepositoryService repositoryService; @Override public boolean startActivityDemo() { System.out.println("method startActivityDemo begin...."); //给占位符赋值 Map<String,Object> map = new HashMap<String,Object>(); map.put("apply","zhangsan"); map.put("approve","lisi"); //流程启动 ExecutionEntity pi1 = (ExecutionEntity) runtimeService.startProcessInstanceByKey("leave",map); //获取当前流程id String processId = pi1.getId(); //获取当前任务id String taskId = taskService.createTaskQuery().processInstanceId(processId).singleResult().getId(); //完成第一步申请,它会自动传递任务到下一层 taskService.complete(taskId); //传递任务到这一层 String taskId2 = taskService.createTaskQuery().processInstanceId(processId).singleResult().getId(); //驳回申请 map.put("pass", false); //完成任务,如果有下一层，则继续传递 taskService.complete(taskId2,map); System.out.println("method startActivityDemo end...."); return false; } }
能用到的就这么多。。。有机会再去看看工作流里面角色相关的东西
