javaactiviti-工作流bcxmlTestJavaScript前端开发


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.SQLServerDriver
jdbc_url=jdbc:sqlserver://localhost:1433;DatabaseName=activiti
jdbc_username=sa
jdbc_password=sa

三、流程文件leave.xml
