1、设置变量
画图xml 文件:sequenceFlow 就代表了上方的双指向箭头
双指向箭头在 idea 插件外面是没有的,须要用后面说的软件,点击指向线点击设置符号就会显示

而后失常流程启动:
-
1、定义
@Test public void Expression(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); Deployment deploy = repositoryService.createDeployment() .name("出差申请流程 -variables") .addClasspathResource("bpmn1/testUpdate.bpmn20.xml") .deploy();}
-
2、启动
// 启动 @Test public void ExpressionStart(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RuntimeService runtimeService = processEngine.getRuntimeService(); // 流程变量的 map Map<String,Object> variables = new HashMap(); // 设置流程变量 Evection evection = new Evection(); // 设置出差日期 evection.setNum(2d); // 把流程变量的 pojo 放入 map variables.put("evection",evection); // 设定工作的负责人 variables.put("assignee0","李四"); variables.put("assignee1","王经理"); variables.put("assignee2","杨总经理"); variables.put("assignee3","张财务"); // 启动流程 runtimeService.startProcessInstanceByKey("dd",variables); }
-
3、提交工作
@Test public void finshActivity1() { // 获取引擎 ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); // 获取操作工作的服务 TaskService TaskService taskService = processEngine.getTaskService(); // 实现工作, 参数:工作 id, 先实现提交工作,在实现经理的首次审批工作,而后看成果会走向总经理还是间接走财务 taskService.complete("35002"); }

2、网关
-
1、排他网关
所有分支都会判断条件是否为 true,如果为 true 就执行该分支
留神:只会抉择一个 true 的分支执行,如果都满足条件,则走 flowid 最小的工作。
与上述条件变量的区别:都不满足条件,则抛出异样。
(一)创立 bpmn 文件
bug 坑:1 如果网关上面只有一条线,就不能够设置条件,因为他本人会把这个线当作默认,如果想只放一条线的话,就须要勾销默认,目前我没有找到勾销办法,所以只能先这样测试。![image_3.png](/img/bVcYEIg) 2 这个中央必须是 true,否则无奈加载流程 **(二)代码:** ```Java /** * 排他网关 */ ** 定义流程 ** @Test public void ExclusiveGetWay(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); Deployment deployment = repositoryService.createDeployment() .addClasspathResource("bpmn1/getway1.bpmn20.xml") .name("出差申请流程 - 排他网关") .deploy();} ** 启动 ** @Test public void ExclusiveStart(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RuntimeService runtimeService = processEngine.getRuntimeService(); Map<String, Object> map = new HashMap(); Evection evection = new Evection(); evection.setNum(3d); // 定义流程变量,把出差 pojo 对象放入 map map.put("evection",evection); // 启动流程实例,并设置流程变量的值(把 map 传入)ProcessInstance processInstance = runtimeService .startProcessInstanceByKey("定义的流程 id", map); 如果不晓得定义的流程 id 的能够会看后面的文章
} ** 实现工作 ** @Test public void finshActivity2() { // 获取引擎 ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); // 获取操作工作的服务 TaskService TaskService taskService = processEngine.getTaskService(); // 实现工作, 参数:工作 id,task 表外面,如果不晓得看后面文章 taskService.complete("工作 id"); } 实现工作后,在上方设置不同的天数进行测试看流程 ```
-
2、并行网关
能够把多条分支汇聚一起,会走所有的分支、还要等多个分支实现才可持续实现。
留神:并行网关不会解析条件,即便定义了条件也会被疏忽。
图:
id 和 name 本人填就行
1 和 2 这两条线表达式相同,判断不同后果
代码:/** * 并行网关 */ // 流程定义 @Test public void ExclusiveGetWay1(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); Deployment deployment = repositoryService.createDeployment() .addClasspathResource("bpmn1/getway2.bpmn20.xml") .name("出差申请流程 - 并行网关") .deploy();} @Test public void ExclusiveStart1(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RuntimeService runtimeService = processEngine.getRuntimeService(); Map<String, Object> map = new HashMap(); Evection evection = new Evection(); evection.setNum(3d); // 定义流程变量,把出差 pojo 对象放入 map map.put("evection",evection); // 启动流程实例,并设置流程变量的值(把 map 传入)ProcessInstance processInstance = runtimeService .startProcessInstanceByKey("bingxing", map); } @Test public void finshActivity3() { // 获取引擎 ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); // 获取操作工作的服务 TaskService TaskService taskService = processEngine.getTaskService(); // 实现工作, 参数:工作 id taskService.complete("105008"); }
都在 task 工作表 定义之后:
实现工作后
将这两个工作都实现后:
总经理工作实现后记录删除;
如果小于 3 天的话,不须要总经理审批,技术经理和项目经理工作实现后,记录间接删除。 - 3、蕴含网关
排他网关和并行网关的联合。都为 ture 的时候,都要执行工作,并且最初汇聚在一起才能够执行上来。
bpmn 文件图
id 和 name 本人设置,这三条线增设条件
2 和 3 的条件一样,1 的条件是 <3
实现 bpmn 文件后,开始进行代码流程
/** * 蕴含网关 */ @Test public void InclusiveGateway(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RepositoryService repositoryService = processEngine.getRepositoryService(); Deployment deployment = repositoryService.createDeployment() .addClasspathResource("bpmn1/getway3.bpmn20.xml") .name("出差申请流程 - 蕴含网关") .deploy();} // 启动 @Test public void InclusiveStart(){ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); RuntimeService runtimeService = processEngine.getRuntimeService(); //key 能够见 bpmn 文件 <process> 标签 id String key = "InclusiveGateway"; Map<String, Object> map = new HashMap(); Evection evection = new Evection(); evection.setNum(2d); // 定义流程变量,把出差 pojo 对象放入 map map.put("evection",evection); // 启动流程实例,并设置流程变量的值(把 map 传入)ProcessInstance processInstance = runtimeService .startProcessInstanceByKey(key, map); } @Test public void finshActivity4() { // 获取引擎 ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine(); // 获取操作工作的服务 TaskService TaskService taskService = processEngine.getTaskService(); // 实现工作, 参数:工作 id taskService.complete("17508");

我集体喜爱看 task 表来察看流程成果,也能够看 execution 表和 hi_tsakinst 表、hi_actinst 表看节点成果
到此对于 idea2019 以上版本的操作 activiti7 就临时完结了,我也是刚开始学,尽量的将我遇见的问题都写进去,看了很多文章也没有看到讲的很粗疏的有时候都是一笔带过,我做的时候会一个中央卡很长时间,所以我就写的尽力的粗疏,大家看到我的文章时也不会太费力气,先入门。
