一、项目依赖
xml

</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.21</version>
</dependency>二、新建Test类
java
public class Test01 {
/**
* 获取流程引擎对象
*/
@Test
public void testProcessEngine() {
// 获取 ProcessEngineConfiguration 对象
ProcessEngineConfiguration configuration = new StandaloneProcessEngineConfiguration();
//配置相关的数据库连接信息
configuration.setJdbcDriver("com.mysql.cj.jdbc.Driver");
configuration.setJdbcUsername("xxx");

configuration.setJdbcUrl("jdbc:mysql://xxx/flowable?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai");
//如果数据库中的表结构不存在就新建
configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
//构建流程引擎对象
ProcessEngine processEngine = configuration.buildProcessEngine();
System.out.println("processEngine = " + processEngine);
}
ProcessEngineConfiguration configuration = null;
@Before

}
/**
* 部署流程
*/
@Test
public void testDeploy() {
//1.获取ProcessEngine 对象
ProcessEngine processEngine = configuration.buildProcessEngine();
//2.获取RepositoryService
RepositoryService repositoryService = processEngine.getRepositoryService();
//3.完成流程部署操作
Deployment deploy = repositoryService.createDeployment()

/**

}
/**
* 删除部署的流程
*/
@Test

RepositoryService repositoryService = processEngine.getRepositoryService();
//删除部署ID为1的，如果部署的流程启动了 则没法删除
// repositoryService.deleteDeployment("1");
// 第二个参数是级联删除，如果流程启动了也可以进行删除，相关的任务也会被删除
repositoryService.deleteDeployment("7501", true);
}
/**
* 启动流程
*/
@Test
public void testStartProcess() {
//id :2501
ProcessEngine processEngine = configuration.buildProcessEngine();
//通过runtimeService 启动流程实例
RuntimeService runtimeService = processEngine.getRuntimeService();
//构建流程变量
Map<String, Object> variable = new HashMap<>();
variable.put("employee", "张三");
variable.put("nrOfHolidays", 3);

}
/**

*/
@Test
public void testQueryTask() {

List<Task> list = taskQuery.processDefinitionKey("holidayRequest")
// .taskAssignee("zhangsan")

System.out.println("task.getName() = " + task.getName());
System.out.println("task.getAssignee() = " + task.getAssignee());
System.out.println("task.getDescription() = " + task.getDescription());
System.out.println("task.getId() = " + task.getId());
}
}
/**
* 处理完成当前任务
*/
@Test
public void testCompleteTask() {
ProcessEngine processEngine = configuration.buildProcessEngine();

System.out.println("处理时间：historicActivityInstance.getDurationInMillis() = " + historicActivityInstance.getDurationInMillis());
System.out.println("------------------");
}
}
}三、flowable流程图
- 新建一个xml文件命名为：
holiday-request.bpmn20.xml
xml
<?xml version="1.0" encoding="UTF-8"?>
