SpringBoot集成Camunda

一：pom.xml

因camunda集成SpringBoot对SpringBoot的版本和JDK的版本都有一定的要求，所以这里贴个完整的依赖。可以去官网找每个SpringBoot的版本对应的camunda版本。

二：application.yml

三：bpmn

将bpmn文件放到src/main/resources/bpmn目录下。

四：部署启动

启动项目时会自动生成表结构，数据库先创建好。

Deployment deploy = repositoryService.createDeployment().name("请假流程").addClasspathResource("bpmn/diagram_1.bpmn").deploy();
// 赋值给StartEvent中的Initiator变量中的值。
identityService.setAuthenticatedUserId("huihui");
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("HelloWordProcess");Task task = taskService.createTaskQuery().processInstanceId(processInstance.getId()).singleResult();
taskService.complete(task.getId());
