Flowable

环境准备

下载flowableUI http://www.flowable.org/downloads.html

将Flowable发行包中，wars文件夹下的flowable-admin.war、flowable-idm.war、flowable-modeler.war与flowable-task.war文件，复制到Tomcat的webapps文件夹下。启动Tomcat http://localhost:8080/flowable-modeler

画一个简单的流程，用到的组件是空启动事件，用户任务，结束事件。用户任务找到属性分配用户写一个固定值张三。

部署流程

连接数据库（会产生很多系统业务表）返回ProcessEngine所有操作都依赖于这个对象

ProcessEngine processEngine;

    @BeforeEach
    public void before() {
        ProcessEngineConfiguration cfg = new StandaloneProcessEngineConfiguration()
                .setJdbcUrl("jdbc:mysql://ip:3306/flowabledb?autoReconnect=true&useSSL=false&characterEncoding=utf-8&serverTimezone=Asia/Shanghai")
                .setJdbcUsername("root")
                .setJdbcPassword("123456")
                .setJdbcDriver("com.mysql.cj.jdbc.Driver")
                .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);

        processEngine = cfg.buildProcessEngine();
    }

部署流程需要流程描述的xml重要属性<process id="test">标记xml的唯一性如果ID相同则产生不同的version

@Test
    public void deploy() {
        RepositoryService repositoryService = processEngine.getRepositoryService();
        Deployment deployment = repositoryService.createDeployment()
                .addClasspathResource("static/test.bpmn20.xml")
                .deploy();
        Assert.assertNotNull(deployment);
    }

创建流程实例

RuntimeService.startProcessInstanceByKey(str)传入已部署的流程的key。对应的是xml中<process id="key">创建流程实例会影响8张表。

这里转载一份flowable数据表的说明博客 https://www.cnblogs.com/xiohao/p/11446622.html

@Test
    public void instances() {
        RuntimeService runtimeService = processEngine.getRuntimeService();
        runtimeService.startProcessInstanceByKey("test2");
    }

查询用户任务

流程中有一个步骤是用户任务，用户任务是flowable的核心功能。每一个流程实例从任务开始沿顺序流（线）往前走，在用户任务步骤处停顿，直到该任务的执行人执行了该任务，流程才会继续往下走。在上边这个简单的流程里用户任务是分配给张三三这个用户的。虽然这里声明了张三三是一个用户实际上flowable并没有帮我们维护用户，只是该任务的完成人是张三三。

查询的表是 select distinct RES.* from ACT_RU_TASK RES WHERE RES.ASSIGNEE_ = '张三三' order by RES.ID_ asc

@Test
    public void queryTask() {
        TaskService taskService = processEngine.getTaskService();
        TaskQuery taskQuery = taskService.createTaskQuery();
        List<Task> tasks = taskQuery.taskAssignee("张三三").list();
        Assert.assertNotNull(tasks);
    }

View Code

用户执行任务

通过任务id(任务ID从数据库中查询)完成该任务，参数是ACT_RU_TASK表中的id，任务一旦完成会删除ACT_RU_TASK行记录并更改ACT_HI_TASKINST行记录。

@Test
    public void completeTask(){
        TaskService taskService = processEngine.getTaskService();
        taskService.complete("20006");
    }

启动事件-空启动事件-执行监听器

空启动事件是启动事件的一种，它有两个执行监听器分别是start，end。分别代表开始结束。

活动-用户任务-任务监听器

用户活动有4种任务监听器顺序分别为assignment（指派），create（创建），complete（完成），delete（删除）。注意assignment在create之前执行。如果任务没有指派用户则assignment监听器不会启动。

满足多个流条件

流1若flag1为true则发布任务给张三，流2若flag2为true则发布任务给李四，流3若flag3为true则发布任务给王五。在监听器中设置flag1,flag2为true，flag3为false。可以看到多个条件满足时会流向多条线路。

并向网关-合并

所有到达并行网关的并行执行都会在网关处等待，直到每一条入口顺序流都到达了并行网关。然后流程经过该合并网关继续。A1执行了两个任务后才分裂出了三个任务。

包容网关-合并

和并行网关一样，到达并行网关的并行执行都会在网关处等待，直到每一条入口顺序流都到达了包容网关。才会继续执行。

包容网关-分支

当A1,A2两个任务执行完毕后。会分裂出两个任务，这与并行网关是有区别的，包容网关允许有条件，只有条件满足的流才会分裂任务。

Create任务监听器初始化参数

在实际应用中我们肯定不会将任务的具体细节写死到xml中，在create中可以分配用户，设置任务过期时间。注意，任务过期时间只是一个时间标记，它并不会将已经过期的任务清理。可以使用API查询任务是否过期Task.getDueDate()

用户任务多实例

可以将一个任务分配给多个执行人.需要设置flowable:collection="assigneesList" flowable:elementVariable="assignee".collection是集合的名字,elementVariable是集合中每个执行人的变量,需要注意的是elementVariable必须和assignee相同,设置collection必须在流程任务监听器前,也就是只能在执行监听器start时初始化.isSequential="false"表示分裂的任务并行创建.如果为true则任务串行创建(第一个执行后才会创建第二个).<completionCondition>接受一个表达式,表示用户任务完成的时机.如果不写则需要全部任务执行结束.

nrOfInstances：实例总数。
nrOfActiveInstances：当前活动的（即未完成的），实例数量。对于顺序多实例，这个值总为1。
nrOfCompletedInstances：已完成的实例数量。

以上三个为系统内置的变量,可以使用表达式 ${nrOfCompletedInstances/nrOfInstances >= 0.5} 它表示有一半的人执该任务则任务就算执行完毕,进行下一个流程.

用户任务多实例-自定义完成条件

以下案例用户任务会分配给三个用户,设置的转移条件是flag如果flag为true则触发转移.定义了任务监听器complete判断已执行次数,然后设置flag但flag这个变量也必须在执行监听器start中设置.
