/**部署流程定义（从inputStream）*/    @Test    public void deploymentProcessDefinition_inputStream(){        InputStream inputStreamBpmn = this.getClass().getResourceAsStream("sequenceFlow.bpmn");        InputStream inputStreamPng = this.getClass().getResourceAsStream("sequenceFlow.png");        Deployment deployment = processEngine.getRepositoryService()//与流程定义和部署对象相关的Service                        .createDeployment()//创建一个部署对象                        .name("连线")//添加部署的名称                        .addInputStream("sequenceFlow.bpmn", inputStreamBpmn)//                        .addInputStream("sequenceFlow.png", inputStreamPng)//                        .deploy();//完成部署        System.out.println("部署ID："+deployment.getId());        System.out.println("部署名称："+deployment.getName());          System.out.println("部署时间："+deployment.getDeploymentTime()); //      部署ID：2601//      部署名称：连线//      部署时间：Wed Sep 06 20:23:15 CST 2017    }    /**启动流程实例*/       @Test    public void startProcessInstance(){        //流程定义的key.,key对应helloworld.bpmn文件中id的属性值，使用key值启动，默认是按照最新版本的流程定义启动        String processDefinitionKey = "sequenceFlow";        ProcessInstance pi = processEngine.getRuntimeService()//与正在执行的流程实例和执行对象相关的Service                        .startProcessInstanceByKey(processDefinitionKey);//使用流程定义的key启动流程实例，        System.out.println("流程实例ID:"+pi.getId());//         System.out.println("流程定义ID:"+pi.getProcessDefinitionId());// //        流程实例ID:2701//        流程定义ID:sequenceFlow:4:2604    }

测试
1先查看陈经理的当前任务

    /**查询当前人的个人任务*/    @Test    public void findMyPersonalTask(){        String assignee = "陈经理";        List<Task> list = processEngine.getTaskService()//与正在执行的任务管理相关的Service                        .createTaskQuery()//创建任务查询对象                        /**查询条件（where部分）*/                        .taskAssignee(assignee)//指定个人任务查询，指定办理人//                      .taskCandidateUser(candidateUser)//组任务的办理人查询//                      .processDefinitionId(processDefinitionId)//使用流程定义ID查询//                      .processInstanceId(processInstanceId)//使用流程实例ID查询//                      .executionId(executionId)//使用执行对象ID查询                        /**排序*/                        .orderByTaskCreateTime().asc()//使用创建时间的升序排列                        /**返回结果集*///                      .singleResult()//返回惟一结果集//                      .count()//返回结果集的数量//                      .listPage(firstResult, maxResults);//分页查询                        .list();//返回列表        if(list!=null && list.size()>0){             System.out.println("--关联表：  ACT_RU_TASK----");                for(Task task:list){                       System.out.println("--------"+task.getAssignee()+"任务:"+task.getName()+"-----------------");                        System.out.println("任务ID:"+task.getId());                        System.out.println("任务名称:"+task.getName());                        System.out.println("任务的创建时间:"+task.getCreateTime());                        System.out.println("任务的办理人:"+task.getAssignee());                        System.out.println("流程实例ID："+task.getProcessInstanceId());                        System.out.println("执行对象ID:"+task.getExecutionId());                        System.out.println("流程定义ID:"+task.getProcessDefinitionId());//                      任务ID:2704//                      任务名称:部门经理审批//                      任务的创建时间:Wed Sep 06 20:23:31 CST 2017//                      任务的办理人:陈经理//                      流程实例ID：2701//                      执行对象ID:2701//                      流程定义ID:sequenceFlow:4:2604                }        }    }

2通过流程变量来控制流程连线

    /**完成我的任务*/    @Test    public void completeMyPersonalTask(){        //任务ID        String taskId = "2704";        //完成任务的同时，设置流程变量，使用流程变量用来指定完成任务后，下一个连线，对应sequenceFlow.bpmn文件中${message=='不重要'}        Map<String, Object> variables = new HashMap<String, Object>();        variables.put("message", "一级费用");//通过流程变量来控制流程的路线        processEngine.getTaskService()//与正在执行的任务管理相关的Service                    .complete(taskId,variables);        System.out.println("完成任务：任务ID："+taskId);//      完成任务：任务ID：2704    }

查看数据库当前运行的任务表
这里写图片描述
可以看到任务已经走到总经理审批了。

同理当完成任务那里设置流程变量为二级费用，那么任务就走向结束
