Question

我想在spring mvc中使用activiti。我的java配置为activiti在下面。当我运行项目时，此异常no processes deployed with key抛出。我把one-vacation-process.bpmn20.xml放在资源文件夹中。我的问题是什么？谢谢你的帮助。

  @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();
}

您需要先部署流程。

有针对不同用例的API，在这里我部署了一个进程，其中resourceName是进程xml的名称（例如one-vacation-process.bpmn20.xml），content实际文件内容为字符串。< / p>

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

请查看org.activiti.engine.repository.DeploymentBuilder哪里有API，如：

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);

Activiti：没有使用键'oneVacationProcess'部署的进程
