使用@Transactional注释时，JdbcTemplate不起作用

Question

在同一函数中使用spring数据和jdbctemplate时 spring数据工作正常，但jdbc更新不起作用。

这是服务类。 jdbc更新然后没有发生错误但数据库没有更新

@Service
public class SampleService {
    private static final Logger logger = LoggerFactory.getLogger(SampleService.class);

    @Inject
    private SampleRepository sampleRepository;

    @Inject
    private JpaTransactionManager transactionManager;

    private JdbcTemplate jdbcTemplate() {
        return new JdbcTemplate(transactionManager.getDataSource());
    }

    @Transactional(propagation=Propagation.REQUIRED)
    public void execute(){

        sampleRepository.deleteAll();
        sampleRepository.save(new Sample("sample"));

        logger.info("data count (after jpa insert) : {}", sampleRepository.count());//1

        int count = jdbcTemplate().update("insert into Sample (sample) values ( ? )", "sample");
        logger.info("jdbc insert count: {}", count);//1

        logger.info("data count (after jdbc insert) : {}", sampleRepository.count());//expected: 2 , actual:1

        count = jdbcTemplate().queryForObject("select count(id) from Sample", Integer.class);
        logger.info("data count (after jdbc insert) : {}", count); //jdbc count query result also return 1

    }

当不使用@Transactional注释时，工作正常。

    public void execute2(){

        DefaultTransactionDefinition def = new DefaultTransactionDefinition();
        def.setName("testTx");
        def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);

        TransactionStatus status = transactionManager.getTransaction(def);

        ... this method work fine ...

        transactionManager.commit(status);

    }

}

这是数据访问配置。
