Spring AOP没有从代理类中注入@Transactional方法中的事务

Question

我们有一个应用程序，我们正在从Spring Boot 1和Hibernate 3.6.8迁移到最新的Spring Boot 2和Hibernate 5.2.17。

一切似乎都没问题，除了我们正在调用一些方法并且没有注入事务。喜欢这项服务：

@Service
public class BreakFixProcessorBO extends BaseProcessorBO  {

    @Transactional  
    public void process(String xml){
        [...]

它是从这个其他类调用的：

@Service
public class BreakFixAmerInternalConsumer extends BaseConsumer {

    private BreakFixProcessorBO breakFixProcessorBO;

    @Autowired
    public BreakFixAmerInternalConsumer(BreakFixProcessorBO breakFixProcessorBO) {
        this.breakFixProcessorBO = breakFixProcessorBO;
    }

    @Override
    protected void proccess(String messageBody) {
        breakFixProcessorBO.process(messageBody);
    }

许多其他代码调用存储库使用@Transactional，许多服务也使用@Transactional，其中许多服务正常工作。除了其中一些不是，我们找不到任何区别。我一直在阅读很多关于事务如何在代理类上工作的文档。并且似乎当类实现接口行为时会发生一些变化。所以我试着用这个方法创建一个接口：

public interface BreakFixProcessorBO_TransactionTest  {
    void process(String xml);
}

并有服务实现它：

@Service
public class BreakFixProcessorBO extends BaseProcessorBO implements BreakFixProcessorBO_TransactionTest {

无所谓我们做什么。我们对某些特定服务有以下例外情况：

似乎Spring AOP成功代理了实例......但是没有创建任何事务。我尝试过Propagation.REQUIRES_NEW，它的行为相同。

我们的PlatformTransactionManager与我们的数据源一起定义：

@Configuration
@EnableTransactionManagement(proxyTargetClass = true)
@EnableAspectJAutoProxy(proxyTargetClass = true)
@RefreshScope
public class DBConfiguration extends DatabaseConfiguration implements EnvironmentAware {
    @Primary
    @Bean
    public LocalSessionFactoryBean sessionFactory() {
        final LocalSessionFactoryBean annotationSessionFactoryBean = new LocalSessionFactoryBean();
        annotationSessionFactoryBean.setDataSource(dataSource());
        annotationSessionFactoryBean.setPackagesToScan("d.s.a");
        annotationSessionFactoryBean.setHibernateProperties(hibernateProperties());
        return annotationSessionFactoryBean;
    }
    @Primary
    @Bean
    public DataSource dataSource() {
        return createDataSource(propertyResolver);
    }
    @Primary
    @Bean
    public PlatformTransactionManager transactionManager() {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory().getObject());
        return txManager;
    }
    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }
}

我们的应用程序使用大多数自动配置：

@SpringBootApplication
@EnableAutoConfiguration(
        exclude = {
                JmsAutoConfiguration.class,
                CamelAutoConfiguration.class
        })
@ImportResource({"classpath:/META-INF/spring/applicationContext.xml"})
@ComponentScan(basePackages = "d.s.a")
public class OurApplication extends SpringBootServletInitializer implements WebApplicationInitializer {
    public static void main(String[] args) {
        if(System.getProperty("debug") != null) { //-Ddebug=true should be a feature
            args = Arrays.copyOf(args, args.length+1);
            args[args.length-1] = "--debug";
        }
        SpringApplication.run(OurApplication.class, args);
    }
}

applicationContext.xml只是我们尚未迁移的一些旧任务运行器定义。我们缺少什么，还是Spring bug？

你有没有尝试过

   @Override
   @Transactional
    protected void proccess(String messageBody) {
        breakFixProcessorBO.process(messageBody);
    }
