Question

关于此异常有很多问题，但经过研究后我认为这并不重复，因为它与已经运行的代码上的版本迁移后的问题有关。

我试图从Spring 4.3.9.RELEASE / Hibernate 4.3.6.Final迁移到Spring 5.0.4.RELEASE / Hibernate 5.2.14.Final。除了根据需要更改依赖关系并根据需要将包名称更改为hibernate5之外，代码不会更改。我一直收到异常 javax.persistence.TransactionRequiredException：没有正在进行的交易

@Transactional属性应用于适当的位置。我做了很多研究，以找出原因，特别是当它适用于从一个版本迁移到另一个版本时。以下日志实际显示事务已启动，但仍然抛出异常

14:39:28,812 TRACE [main] org.hibernate.resource.jdbc.internal.AbstractLogicalConnectionImplementor.rollback(AbstractLogicalConnectionImplementor.java:115) - Preparing to rollback transaction via JDBC Connection.rollback()

很多调试让我跟随函数org.hibernate.resource.transaction.backend.jdbc.internal.JdbcResourceLocalTransactionCoordinatorImpl.isJoined（），其中physicalTransactionDelegate为null。因为isJoined函数返回false，所以抛出异常。

@Override
public boolean isJoined() {
    return physicalTransactionDelegate != null && getTransactionDriverControl().isActive( true );
}

它的java配置。代码崩溃非常简单。有人已经自动装配一个dao并调用以下方法。它基本上检查记录是否存在于数据库中，如果它存在，更新它或创建一个新记录。

@Transactional(propagation = Propagation.REQUIRED)
public void registerApplication(final ApplicationType type, final Class<?> versionedClass, final String extraData) throws Exception {
    final Properties pr = getVersionInformation(versionedClass);
    final String commit = pr.getProperty("git.commit.id");
    if (commit == null) {
        throw new NullPointerException("Could not find property git.commit.id");
    }
    VersionInfo info = extraData == null ? findBy(type, commit) : findBy(type, commit, extraData);
    if (info != null) {
        log.info("Found entry for the version, just updating usage count");
        info.incrementUsageCount();
    } else {
        info = new VersionInfo();
        info.setApplicationType(type);
        info.setCommitId(commit);
        info.incrementUsageCount();
        info.setExtraData(extraData);
    }
    save(info);
    log.info("Saved version information for {}:{}:{}", type, commit, extraData);
}

我应该在代码中更改哪些内容才能让它再次运行？
