在camunda中使用java api完成简单的审核流程并包含leave_process.bpmn 流程定义文件

好的,首先需要确保你已经安装了Camunda BPM。然后,你需要创建一个Java项目,并添加以下依赖项到pom.xml文件中:
```xml
<dependency>
<groupId>org.camunda.bpm</groupId>
<artifactId>camunda-engine</artifactId>
<version>7.14.0</version>
</dependency>
<dependency>
<groupId>org.camunda.bpm</groupId>
<artifactId>camunda-engine-spring</artifactId>
<version>7.14.0</version>
</dependency>
```
接下来,你需要在Java代码中定义一个Camunda流程引擎,并使用它来启动你的流程。
```java
import org.camunda.bpm.engine.ProcessEngine;
import org.camunda.bpm.engine.ProcessEngineConfiguration;
import org.camunda.bpm.engine.repository.Deployment;
import org.camunda.bpm.engine.repository.DeploymentBuilder;
import org.camunda.bpm.engine.runtime.ProcessInstance;
public class CamundaDemo {
public static void main(String[] args) {
ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()
.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_CREATE_DROP)
.setJdbcDriver("com.mysql.jdbc.Driver")
.setJdbcUrl("jdbc:mysql://localhost:3306/camunda")
.setJdbcUsername("root")
.setJdbcPassword("password")
.buildProcessEngine();
DeploymentBuilder deploymentBuilder = processEngine.getRepositoryService().createDeployment();
deploymentBuilder.addClasspathResource("leave_process.bpmn");
Deployment deployment = deploymentBuilder.deploy();
ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceByKey("leave_process");
System.out.println("Process instance id: " + processInstance.getId());
}
}
```
在上面的代码中,我们首先创建了一个ProcessEngine对象并指定了数据库连接信息。然后,我们使用该对象加载了我们的BPMN文件,并将其部署到流程引擎中。最后,我们启动了流程实例并打印了它的ID。
现在,你可以在你的Camunda Cockpit中看到已经成功启动了一个名为"leave_process"的流程。
