java - 正在解析 'The process engine you are trying to access does not exist'

Question

我正在我的应用程序中运行嵌入式 camunda 引擎。现在我想在具有相同数据库的不同容器上运行带有驾驶舱的第二个 camunda 引擎。我所做的基本上是复制粘贴我的主应用程序配置，仅从 camunda-bpm-spring-boot-starter 切换依赖项至camunda-bpm-spring-boot-starter-webapp 。我可以访问驾驶舱主页，但我立即收到提示 The process engine you are trying to access does not exist我不明白为什么？启动时我可以看到我的 SpringProcessEngineConfiguration bean 已创建以及 ProcessEngineFactoryBean bean 。 但是:

BpmPlatform.getProcessEngineService().getProcessEngineNames();

返回空集。 你能看一下并指出我的错误吗？

主应用程序类:

@SpringBootApplication
public class CamundaCockpitApplication {

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

卡蒙达 session :

@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;
}
}

您需要在主类中添加@EnableProcessApplication注释。
