由 三世轮回 提交于 2019-12-11 03:24:51
问题 Whenever I need to make a change in the process definition I have to re deploy the process definition.It seems that creates a new version of the process definition. Is there a way where I can update the existing process definition and not create a new version all the time. What will happen to the old process instances if there is a new version of process definition in place. Any help on the above queries is appreciated. 回答1: I don't think the Activiti API provides a way to replace an existing

第十二节:Activiti6.0——四种边界事件：定时器、错误、信号、补偿

由 谁说我不能喝 提交于 2019-12-10 20:36:30
一、概述 边界事件 ：边界事件属于一种特殊的中间事件。区别是： 中间事件 可以单独作为流程元素存在于流程中，而 边界事件 必须附属于某个流程元素（如任务、子流程等）。边界事件是Catching事件。 二、定时器边界事件 说明 ：定时器边界事件会在定时器时间到了之后进行触发，需要开启异步执行器（在activiti.cfg.xml中）。此处模拟一个损坏的物品首先交给初级工程师修理，定时1分钟后没有修好就给中级工程师修理 流程图 流程的xml < process id = " myProcess_1 " isClosed = " false " isExecutable = " true " processType = " None " > < startEvent id = " startEvent1 " name = " StartEvent " /> < userTask activiti: exclusive = " true " id = " userTask1 " name = " 初级工程师维修 " /> <!--cancelActivity属性是触发边界事件后，原流程是否取消，为true是取消，取消是在数据库中删除对应的数据--> < boundaryEvent attachedToRef = " userTask1 " cancelActivity = " true "

Complex Activiti + JPA queries

由 好久不见. 提交于 2019-12-10 14:19:17
问题 We are trying to use Activiti in a new project. I've created a setup which uses Hibernate through JPA for persisting entities involved in the process and JPA is interconnected with Activiti so we can use these entities as JPA variables. See: JPA chapter of Activiti's documentation I've found out that Activiti doesn't allow me to create queries on processes which involves JPA variables where i like to filter on the JPA entity fields. For example if i have processes with a variable referencing

问题 How would I use two separate dataSources in my Spring Boot application?

As of now Activiti's tables and my app's tables are created in the same database. [Edited]: I know I can define two separate DataSource beans like: @Bean public DataSource appDataSource() { BasicDataSource dataSource =

5.1.4节给出了一个创建用户、组，并用完成用户任务的一个例子。 1、测试类继承了抽象类AbstractTest，它中有标注@BeforeClass、@AfterClass、@Before的注解： @Before：初始化方法 对于每一个测试方法都要执行一次（注意与 BeforeClass区别，后者是对于所有方法执行一次） @After：释放资源 对于每一个测试方法都要执行一次（注意与AfterClass区别，后者是对于所有方法执行一次） @BeforeClass： 针对所有测试，只执行一次 ，且 必须为static void @AfterClass： 针对所有测试，只执行一次 ，且 必须为static void 一个JUnit4的单元测试用例执行顺序为： @BeforeClass -> @Before -> @Test -> @After -> @AfterClass; 每一个测试方法的调用顺序为： @Before -> @Test -> @After; 2、用@org.activiti.engine.test.Deployment注解导入bpmn文件： @Deployment(resources = {"chapter5/candidateUserInUserTask.bpmn"}) 起始路径是classpath，故上述导入文件应在classes/chapter5/

Activiti5.9换成MySQL数据库

由 北慕城南 提交于 2019-12-09 14:10:15
本人博客开始迁移，博客整个架构自己搭建及编码 http://www.cookqq.com/listBlog.action Activiti5.9默认的数据库是db，可是我们项目中运用的是mysql，那只好把db换成mysql 步骤： 1.下载activiti-5.9.zip 2.解压activiti-5.10.zip并移动(ACTIVITI_HOME=D:\myspace\activiti-5.9) 3.修改ACTIVITI_HOME\setup\build.db.properties文件，使用MySQL配置，本例如下： #MySQL Config db=mysql jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/activiti?autoReconnect=true jdbc.username=root jdbc.password=1234 4.复制MySQL驱动到ACTIVITI_HOME\setup\files\dependencies\libs下(mysql-connector-java-5.1.15-bin.jar) 5.修改ACTIVITI_HOME\setup\build.xml文件,添加MySQL的驱动路径 原内容： <target name="internal
