Question

我在我的应用程序中运行ning 嵌入式 camunda 引擎。现在我想运行第二个带驾驶舱的 camunda 引擎在具有相同数据库的不同容器上。我所做的基本上是我的主要应用程序配置的 copy-paste 仅将依赖项从 camunda-bpm-spring-boot-starter 切换到 camunda-bpm-spring-boot-starter-webapp。我可以访问驾驶舱主页，但系统立即提示我 The process engine you are trying to access does not exist，我不明白为什么？在启动时，我可以看到创建了我的 SpringProcessEngineConfiguration bean 以及 ProcessEngineFactoryBean bean。然而：

BpmPlatform.getProcessEngineService().getProcessEngineNames();

returns空集。你能看看并指出我的错误吗？

主应用程序 class:

@SpringBootApplication
public class CamundaCockpitApplication {

public static void main(String[] args) {
    SpringApplication.run(CamundaCockpitApplication.class, args);
    BpmPlatform.getProcessEngineService().getProcessEngineNames();
}

卡蒙达会议：

@Configuration
@RequiredArgsConstructor
public class EngineConfiguration {

private final DataSource dataSource;

private final PlatformTransactionManager transactionManager;

private final ResourcePatternResolver resourcePatternResolver;

@Bean
public SpringProcessEngineConfiguration springProcessEngineConfiguration() {
    SpringProcessEngineConfiguration springConfiguration = new SpringProcessEngineConfiguration();
    springConfiguration.setDataSource(dataSource);
    springConfiguration.setTransactionManager(transactionManager);
    springConfiguration.setDatabaseSchemaUpdate("false");
    springConfiguration.setJobExecutorActivate(false);
    springConfiguration.setHistory("full");
    springConfiguration.setJdbcBatchProcessing(false);
    return springConfiguration;
}

@Bean
public ProcessEngineFactoryBean processEngineFactoryBean() {
    ProcessEngineFactoryBean engine = new ProcessEngineFactoryBean();
    engine.setProcessEngineConfiguration(springProcessEngineConfiguration());
    return engine;
}
}

您需要在主 class 中添加 @EnableProcessApplication 注释。
