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
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
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
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
@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
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
@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
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
@Test public void queryTask() { TaskService taskService = processEngine.getTaskService(); TaskQuery taskQuery = taskService.createTaskQuery(); List<Task> tasks = taskQuery.taskAssignee("张三三").list(); Assert.assertNotNull(tasks); }
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。
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
@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。

排他网关
排他网关不需要额外的设置,它判断出流向的条件选择一条为true的流如果有多个则只会选择最先定义。下边的demo流1和流2都为true但只选择了最先定义的李四。

并行网关-分支
以下并行网关有三条分支,流1,流2的条件为true流3的条件为false但是最终三个分支都会执行。如果连接到并行网关的顺序流上定义了条件,会直接忽略该条件

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-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.
