一、从创建表到办理完成任务

public class LeaveActionTest {    private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();    //1.1、创建表    public static void createTabelAuto(){        //创建对象        ProcessEngineConfiguration conf = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();        String driver = PropertiesUtil.getValue("jdbc_driver", "conf/jdbc.properties");        String url = PropertiesUtil.getValue("jdbc_url", "conf/jdbc.properties");        String username = PropertiesUtil.getValue("jdbc_username", "conf/jdbc.properties");        String password = PropertiesUtil.getValue("jdbc_password", "conf/jdbc.properties");        //设置数据库        conf.setJdbcDriver(driver);        conf.setJdbcUrl(url);        conf.setJdbcUsername(username);        conf.setJdbcPassword(password);        //自动建表        conf.setDatabaseSchemaUpdate("true");        //创建引擎        ProcessEngine processEngine = conf.buildProcessEngine();    }    //1.2、创建表,processEngineConfiguration为数据库实体bean    public static void createTabelByXML(){        //创建对象        String resource = "activiti-context2.xml";        String beanName = "processEngineConfiguration";        ProcessEngineConfiguration conf = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource(resource, beanName);        //创建引擎        ProcessEngine processEngine = conf.buildProcessEngine();    }    //2、部署流程定义    @Test    public void deployLeave() throws Exception {        DeploymentBuilder builder = processEngine.getRepositoryService().createDeployment();        builder.addClasspathResource("flow/leave.bpmn");        builder.addClasspathResource("flow/leave.png");        Deployment deploy = builder.deploy();        System.out.println("deploy.getId()==" + deploy.getId());    }    //3、获得流程定义的id    @Test    public void queryFinition() throws Exception {        ProcessDefinitionQuery query = processEngine.getRepositoryService().createProcessDefinitionQuery();        //添加过滤条件        query.processDefinitionKey("leaveFlow");        //添加排序        query.orderByProcessDefinitionVersion().desc();        //分页        query.listPage(0, 10);        List<ProcessDefinition> processDefinitions = query.list();        for (ProcessDefinition p : processDefinitions) {            System.out.println("p.getId()===" +p.getId());        }    }    @Test    public void querys() throws Exception {        List<ProcessDefinition> processDefinitions = processEngine.getRepositoryService().createProcessDefinitionQuery().list();        List<Deployment> deployments = processEngine.getRepositoryService().createDeploymentQuery().list();        List<ProcessInstance> processInstances = processEngine.getRuntimeService().createProcessInstanceQuery().list();        List<Task> tasks = processEngine.getTaskService().createTaskQuery().list();    }    //4、根据流程定义的id获得流程实例的id    @Test    public void getProcessInstance() throws Exception {        String processDefinitionId = "leaveFlow:1:4";        ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceById(processDefinitionId);        System.out.println("processInstance.getId()===" + processInstance.getId());    }    //5、根据流程实例，查询任务列表  ,说明一个流程定义对应多个流程实例，一个流程实例对应多个任务列表    @Test    public void getProcessTask() throws Exception {        String processInstanceId = "5001";        //1        //String assignee = "tom";        //2        //String assignee = "jack";        //3        String assignee = "smith";        //任务列表        TaskQuery taskQuery = processEngine.getTaskService().createTaskQuery();        //查询tom的任务列表        taskQuery.taskAssignee(assignee);        List<Task> tasks = taskQuery.list();        for (Task task: tasks){            System.out.println(task.getId() + ":" + task.getName());        }    }    //6、办理任务,办理完成后，第三步就找不到tom的这个任务了，跑到下个jack的任务中了,5与6是相互重复的    @Test    public void dealProcessTask() throws Exception {        String taskId = "";        processEngine.getTaskService().complete(taskId);    }}

二、数据库配置

jdbc_driver=com.microsoft.sqlserver.jdbc.SQLServerDriverjdbc_url=jdbc:sqlserver://localhost:1433;DatabaseName=activitijdbc_username=sajdbc_password=sa

三、流程文件leave.xml
