如何在Activiti（ServiceTask）的表达式中使用spring bean？

  • 772

不能在 Activiti 的表达式中使用 bean（在 ServiceTask 中）。他写道，他没有看到这个垃圾箱。摘自 pom 按版本：

<springframework.version>5.0.2.RELEASE</springframework.version>
        <springframework.boot>2.0.4.RELEASE</springframework.boot>
        <activiti.version>6.0.0</activiti.version>

Bean 由类上的注释定义。bpmn 模式文件的摘录：

<serviceTask id="SendStatus104" name="Формирование и отправка статуса" activiti:expression="${sendService.sendStatusCode(104)}">
  <documentation>Формирование и отправка статуса</documentation>
</serviceTask>

类声明：

    @Service("sendService")
public class SendServiceImpl implements SendService {
//some code
}
java

    您需要使用其他类来创建 Activity 配置 bean：

    @Bean
SpringProcessEngineConfiguration processEngineConfiguration(@Qualifier("dataSourceForActiviti") DataSource dataSourceForActiviti,
                                                            @Qualifier("transactionManagerForActiviti") PlatformTransactionManager transactionManagerForActiviti) {
    SpringProcessEngineConfiguration processEngineConfiguration = new SpringProcessEngineConfiguration();
    processEngineConfiguration.setTransactionManager(transactionManagerForActiviti);

    processEngineConfiguration.setDataSource(dataSourceForActiviti)
            .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
            .setAsyncExecutorActivate(true)
    ;

    processEngineConfiguration.setDeploymentResources(new Resource[]{
            new ClassPathResource("bpm/1LicensingProcess.bpmn20.xml"),
            new ClassPathResource("bpm/2ReissuanceLicenseProcess.bpmn20.xml"),
            new ClassPathResource("bpm/3IssueOfDuplicateProcess.bpmn20.xml"),
            new ClassPathResource("bpm/4IssuanceOfCopyProcess.bpmn20.xml"),
            new ClassPathResource("bpm/5TerminationOfLicenseProcess.bpmn20.xml"),
            new ClassPathResource("bpm/RLic6ExtractFromRegisterOfLicensesProcess.bpmn20.xml")
    });


    return processEngineConfiguration;
}

@Bean
ProcessEngineFactoryBean processEngineFactoryBean(SpringProcessEngineConfiguration processEngineConfiguration) {
    ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
    processEngineFactoryBean.setProcessEngineConfiguration(processEngineConfiguration);
    return processEngineFactoryBean;
}

    要创建 Activity 服务对象，您需要这样做（以服务为例RepositoryService）：

    @Bean
RepositoryService repositoryService(ProcessEngineFactoryBean processEngineFactoryBean) throws Exception {
    return processEngineFactoryBean.getObject().getRepositoryService();
}
