Question

我非常确定我的Spring Boot应用程序中没有应用事务，即使我正在使用@EnableTransactionManagement(mode=AdviceMode.ASPECTJ)＆amp;在我的应用中有spring-aspects。

配置

@Configuration
public class DatastoreConfig{    
    @Bean
    public DataSource dataSource(){ ///... }

    @Bean
    public JdbcTemplate jdbcTemplate(DataSource dataSource){
        return new JdbcTemplate(dataSource);
    }

    @Bean
    public String databaseSchema(){
        return "mySchema";
    }

    @Bean
    public OpenSessionInViewInterceptor openSessionInViewInterceptor(SessionFactory sessionFactory){
        OpenSessionInViewInterceptor result = new OpenSessionInViewInterceptor();
        result.setSessionFactory(sessionFactory);
        return result;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter vendorAdapter){
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan( Main.class.getPackage().getName() + ".model");
        factory.setDataSource(dataSource);
        factory.setJpaProperties(getJpaProperties());
        factory.afterPropertiesSet();
        return factory;
    }

    @Bean
    public HibernateJpaVendorAdapter jpaVendorAdapter(){
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(false);
        vendorAdapter.setDatabasePlatform(PostgreSQL9Dialect.class.getName());
        return vendorAdapter;
    }

    @Bean
    public SessionFactory sessionFactory(HibernateEntityManagerFactory emf){
        SessionFactoryImpl sf = (SessionFactoryImpl) emf.getSessionFactory();
        return sf;
    }

    private Properties getJpaProperties() {
        Properties props = new Properties();
//        props.put("hibernate.hbm2ddl.auto", "validate");
        props.put("hibernate.ejb.naming_strategy", ImprovedNamingStrategy.class.getName());
        props.put("hibernate.enable_lazy_load_no_trans", "true");
        props.put("jadira.usertype.autoRegisterUserTypes", "true");
        return props;
    }

    @Bean
    public JpaTransactionManager transactionManager(EntityManagerFactory emf) throws PropertyVetoException {
        JpaTransactionManager transactionManager = new JpaTransactionManager(emf);
        transactionManager.setRollbackOnCommitFailure(true);
        transactionManager.setDataSource(dataSource());
        return transactionManager;
    }

    @Bean
    public NamedParameterJdbcTemplate namedParameterJdbcTemplate(DataSource dataSource) {
        return new NamedParameterJdbcTemplate(dataSource);
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

}

    }

    public static void main(String[] args) {
        Object[] sources = {
            Main.class,
            TomcatConfig.class // include for embedded tomcat...
        };
        ConfigurableApplicationContext result = SpringApplication.run(sources, args);
    }

}

尝试验证

我尝试验证的方法之一是运行

@Component
public class SomeService{
    @Transactional
    @Override
    protected void tryItOut(){
            // this is always false
            boolean declarativeTransaction = TransactionSynchronizationManager.isActualTransactionActive();
            // this throws an exception
            TransactionStatus aspect = TransactionAspectSupport.currentTransactionStatus();
    }
}

但是，如果我事先向transactionManager.getTransaction(new DefaultTransactionDefinition());拨打电话，declarativeTransaction为true。

有关如何设置@Transactions /验证它们是否正常工作的任何建议？

您的配置自相矛盾。

@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)

表示您正在使用方面的加载时间或编译时编织。判断您的配置，您没有使用它。如果我必须判断你的配置你只是使用基本代理而不是编织。只需删除AdviceMode.ASPECTJ它就可以了，你也不需要@EnableAspectJAutoProxy因为申请交易与我们无关它（没有它可以工作）。

此外，您的配置基本上没有使用Spring Boot。你已经自动配置了很多弹簧启动已经为你做的事情。

Spring Boot已经为您配置了以下内容（仅指定@EnableAutoConfiguration。

的EntityManagerFactory
数据源
的JdbcTemplate
交易设置
OpenEntityManagerInView
Spring Web Sockets
超媒体支持
Spring Data JPA设置

您可以移除大量配置并在application.properties中添加一些属性。

如果您真的需要SessionFactory而不是自己投票，我强烈建议您使用HibernateJpaSessionFactoryBean。

我怀疑以下主类仍然有效（启用了事务）。

@Configuration
@ComponentScan
@EnableAsync
@EnableScheduling
@EnableAutoConfiguration
@EnableGlobalMethodSecurity(securedEnabled = true, prePostEnabled = true)
@EnableWebSocketMessageBroker
@Slf4j
public class Main extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(
            SpringApplicationBuilder application) {
        return application.sources(Main.class);
    }

    public static void main(String[] args) {
        Object[] sources = {
            Main.class,
            TomcatConfig.class // include for embedded tomcat...
        };
        ConfigurableApplicationContext result = SpringApplication.run(sources, args);
    }

}

使用此DatastoreConfig类

@Configuration
public class DatastoreConfig{    

    @Bean
    public FactoryBean<SessionFactory> sessionFactory(EntityManagerFactory emf){
        HibernateJpaSessionFactoryBean jpaSessionFactoryBean = new HibernateJpaSessionFactoryBean();
        jpaSessionFactoryBean.setEntityManagerFactory(emf);
        return jpaSessionFactoryBean;
    }
}

这是application.properties

spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true
spring.jpa.properties.jadira.usertype.autoRegisterUserTypes=true
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect

您可能需要添加一些spring.datasource.属性才能正确设置数据源。还要判断您使用的是OpenSessionInViewInterceptor，而不是OpenEntityManagerInViewInterceptor（或过滤器）。所以你甚至可以删除它。

不确定这是否是您的配置，但您可以删除/减少更多。我建议您查看Spring Boot参考指南，了解已经自动配置的内容。
