我的服务（使用主数据源的jobExecutor）在从spring MVC控制器调用时工作正常，但是从调度方法调用时总是抛出“TransactionRequiredException：没有正在进行的事务”。原因看起来从 scheduleThreadPool 绑定到线程的 jdbcTransaction 具有 NOT_ACTIVE 作为 localStatus。该事务是针对主数据源的，默认情况下开始于 DataSourceTransactionManager。

我正在使用 spring-boot、spring-data 和 hibernate，以下是这些版本

弹簧启动：1.2.7.RELEASE

休眠核心：4.3.11.Final

休眠实体管理器：4.3.11.Final

也使用java配置

服务器配置.java

@Configuration
@EnableAutoConfiguration
@EnableScheduling
@EnableAsync
@EnableAspectJAutoProxy
@ComponentScan("com.my.client")
@EnableTransactionManagement
@EntityScan(basePackages = {"com.my.database.model"})
@EnableJpaRepositories(
    transactionManagerRef = "transactionManager",
    basePackages = {"com.my.database.repository"})
public class ServerConfig extends SpringBootServletInitializer implements SchedulingConfigurer, AsyncConfigurer {

    static Logger log = Logger.getLogger(ServerModeConfig.class.getName());

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskExecutor());
    }

    /**
     * get executor for scheduling job
     * @return scheduled executor
     */
    @Bean(destroyMethod="shutdown")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(20);
    }

    /**
     * get executor for async job
     * @return executor for asynchronous job but no time limit
     */
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(20);
        executor.setMaxPoolSize(100);
        executor.setQueueCapacity(200);
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new MyClientAsyncExceptionHandler();
    }

}

MyScheduler.java

@Component
public class MyScheduler {

    @Autowired
    protected JobExecutor jobExecutor;

    @Override
    @Scheduled(cron = "0 */1 * * * *") // every minute
    public void run() {
        log.info("Trigger job");
        jobExecutor.execute();
    }
}

服务层

JobExecutorImpl.java

@Service("jobExecutor")
@Transactional("transactionManager")
public class JobExecutorImpl implements JobExecutor {

    static Logger log = Logger.getLogger(JobExecutorImpl.class.getName());

    @Override
    public ClientJobBehaviour execute() {
        log.info("transaction exists? ".concat( String.valueOf(TransactionSynchronizationManager.isActualTransactionActive()) )); // true
        log.info("transaction sync? ".concat( String.valueOf(TransactionSynchronizationManager.isSynchronizationActive()) ));  // true

        ClientJobBehaviour job = new ClientJobBehaviour();
        JobInstance jobInstance = new JobInstance();
        jobInstance.setStatus(JobStatus.STARTED.toString());
        jobInstance = jobInstanceRepository.save(jobInstance);
        jobInstanceRepository.flush();  // throws TransactionRequiredException
        job.setInstanceId(jobInstance.getId());
        return job;
    }
}

内部数据源的 Spring Data JPA 存储库

JobInstanceRepository.java

@Repository
public interface JobInstanceRepository extends JpaRepository<JobInstance, Long>{

}

外部数据源的配置。这使用 JpaTransactionManager 并命名为 adapterTransactionManager。外部数据源的存储库看起来工作正常

ExternalRepositoryConfig.java

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "adapterEntityManagerFactory",
        transactionManagerRef = "adapterTransactionManager",
        basePackages = {"com.my.adapter.database.repository"})
public class ExternalRepositoryConfig {
    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Value("${adapter.datasource.url}")
    private String databaseUrl;

    @Value("${adapter.datasource.username}")
    private String username;

    @Value("${adapter.datasource.password}")
    private String password;

    @Value("${adapter.datasource.hibernate.dialect}")
    private String dialect;

    public DataSource dataSource() {
        return new DriverManagerDataSource(databaseUrl, username, password);
    }

    @Bean(name = "adapterEntityManager")
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Bean(name = "adapterEntityManagerFactory")
    public EntityManagerFactory entityManagerFactory() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.dialect", dialect);

        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(dataSource());
        emf.setJpaVendorAdapter(jpaVendorAdapter);
        emf.setPackagesToScan("com.my.client.another.database.model");
        emf.setPersistenceUnitName("adapterPersistenceUnit");
        emf.setJpaProperties(properties);
        emf.afterPropertiesSet();
        return emf.getObject();
    }

    @Bean(name = "adapterTransactionManager")
    public PlatformTransactionManager transactionManager() {
        return new JpaTransactionManager(entityManagerFactory());
    }
}

当我调试时，我可以看到 jdbcTransaction 的 localStatus 是 NOT_ACTIVE 并且下面的休眠方法抛出异常

AbstractEntityManagerImpl.java

private void checkTransactionNeeded() {
    if ( !isTransactionInProgress() ) {
        throw new TransactionRequiredException(
                "no transaction is in progress"
        );
    }
}

我们有两个数据源，一个供内部使用，另一个供外部使用

应用程序属性

我通过更改内部数据源的 transactionManager 配置解决了这个问题。它看起来默认的 transactionManager 是由 DataSourceTransactionManager 配置的，@EnableTransactionManagement并且如果作业来自任何调度程序，则不会调用休眠 AbstractTransactionImpl 上的 begin() 方法。因此，我将内部数据源的DataSourceTransactionManager更改为JpaTransactionManager，如下所示。现在，无论作业来自调度程序还是 UI，两个 dataSource 的所有事务都成功进行。所以我认为我在这篇文章中解决的问题已得到解决

@Configuration
@EnableAutoConfiguration
@EnableScheduling
@EnableAsync
@EnableAspectJAutoProxy
@ComponentScan("com.my.client")
@EnableTransactionManagement
@EnableJpaRepositories(
    entityManagerFactoryRef = "entityManagerFactory",
    transactionManagerRef = "transactionManager",
    basePackages = {"com.my.database.repository"})
public class ServerConfig extends SpringBootServletInitializer implements SchedulingConfigurer, AsyncConfigurer {

    static Logger log = Logger.getLogger(ServerModeConfig.class.getName());

    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Autowired
    DataSource dataSource;

    @Bean(name = "entityManager")
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    EntityManagerFactory entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(dataSource);
        emf.setJpaVendorAdapter(jpaVendorAdapter);
        emf.setPackagesToScan("com.my.client.database.model");
        emf.setPersistenceUnitName("default");
        emf.afterPropertiesSet();
        return emf.getObject();
    }

    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager tm = new JpaTransactionManager();
        tm.setEntityManagerFactory(entityManagerFactory());
        return tm;
    }

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskExecutor());
    }

    /**
     * get executor for scheduling job
     * @return scheduled executor
     */
    @Bean(destroyMethod="shutdown")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(20);
    }

    /**
     * get executor for async job
     * @return executor for asynchronous job but no time limit
     */
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(20);
        executor.setMaxPoolSize(100);
        executor.setQueueCapacity(200);
        executor.initialize();
        return executor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new MyClientAsyncExceptionHandler();
    }

}

我对@Transactional @Scheduled 方法有同样的问题。公开方法解决了这个问题。我不知道为什么！

只是添加@Transactional到方法或类对我不起作用，我必须添加事务管理器的 bean 名称，然后使用@Transactional(value="entityTransactionManager") 它工作正常。

我建议尝试使您的、回购交易或从您的项目中禁用您的交易属性并尝试一下。当您尝试从事务上下文访问非事务上下文时，可能会发生这种情况。

@Repository
@Transactional
public interface JobInstanceRepository extends JpaRepository<JobInstance, Long>{

}

史蒂夫，Spring 有报道可能与此有关吗？https://jira.spring.io/browse/SPR-5082。

尝试从 JobExecutorImpl 中删除 @Service 注释并使用 @Bean 将其添加到您的 ServerConfig 类中。

另外，我会临时删除 @EnableAspectJAutoProxy 以查看是否与方面扫描有任何冲突。在找到根本问题时，至少不要担心一件事。
