java - Activiti:没有使用 key 'oneVacationProcess' 部署进程

Question

我想在spring mvc中使用activiti。我的 activiti java 配置如下。当我运行项目时，此异常没有使用 key 部署进程抛出。我将 one-vacation-process.bpmn20.xml 放在资源文件夹中。我的问题是什么？感谢您的帮助。

  @Configuration
  public class ActivitiConfig {

@Bean
public ProcessEngine processEngine(ProcessEngineConfigurationImpl pec, ApplicationContext applicationContext) throws Exception {
    ProcessEngineFactoryBean pe = new ProcessEngineFactoryBean();
    pe.setProcessEngineConfiguration(pec);
    pe.setApplicationContext(applicationContext);

    return pe.getObject();
}

@Bean
public ProcessEngineConfigurationImpl getProcessEngineConfiguration(
        DataSource dataSource,
        PlatformTransactionManager transactionManager,
        ApplicationContext context) {
    SpringProcessEngineConfiguration pec = new SpringProcessEngineConfiguration();

    pec.setDataSource(dataSource);
    pec.setDatabaseSchemaUpdate("true");
    pec.setJobExecutorActivate(true);
    pec.setHistory("full");
    pec.setMailServerPort(2025);
    pec.setDatabaseType("mysql");

    pec.setTransactionManager(transactionManager);
    pec.setApplicationContext(context);

    return pec;
}

@Bean
public RuntimeService getRuntimeService(ProcessEngine processEngine) {
    return processEngine.getRuntimeService();
}
@Bean
public TaskService taskService(ProcessEngine processEngine) throws Exception {
    return processEngine.getTaskService();
}

您需要先部署您的流程。

有针对不同用例的 API，这里我部署了一个流程，其中 resourceName 是流程 xml 的名称(例如 one-vacation-process.bpmn20.xml) content 实际文件内容作为字符串。

RepositoryService repositoryService = processEngine.getRepositoryService();
DeploymentBuilder builder = repositoryService.createDeployment().addString(resourceName, content);
builder.enableDuplicateFiltering().deploy();

看看 org.activiti.engine.repository.DeploymentBuilder ，其中有如下 API:

DeploymentBuilder addInputStream(String resourceName, InputStream inputStream);
DeploymentBuilder addClasspathResource(String resource);
DeploymentBuilder addString(String resourceName, String text);
DeploymentBuilder addZipInputStream(ZipInputStream zipInputStream);
DeploymentBuilder addBpmnModel(String resourceName, BpmnModel bpmnModel);
