在尝试使用我的@Service注释类时，我会得到以下异常：

初始化应用程序的方式很复杂，因此我需要提供一个指向完整基本代码的链接，以获得更多信息：https://github.com/dtrunk90/webapp-base。我用这个作为maven覆盖。

以下是必要的代码：

初始化器(来自webapp-base)：

public abstract class AbstractWebApplicationInitializer extends AbstractDispatcherServletInitializer {
    @Override
    protected String[] getServletMappings() {
        return new String[] {"/*"};
    }

    @Override
    protected Filter[] getServletFilters() {
        CharacterEncodingFilter encodingFilter = new CharacterEncodingFilter();
        encodingFilter.setEncoding("UTF-8");
        encodingFilter.setForceEncoding(true);
        return new Filter[] {encodingFilter};
    }

    @Override
    protected WebApplicationContext createRootApplicationContext() {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();

        ConfigurableEnvironment environment = rootContext.getEnvironment();
        environment.setDefaultProfiles("production");

        PropertyUtil propertyUtil = PropertyUtil.getInstance(environment.getActiveProfiles());
        String[] basePackages = propertyUtil.getPropertySplitTrimmed("webapp", "basePackages");
        rootContext.scan(basePackages);

        return rootContext;
    }

    @Override
    protected WebApplicationContext createServletApplicationContext() {
        return new AnnotationConfigWebApplicationContext();
    }
}

初始化器(来自我的webapp应用程序)：

public class WebApplicationInitializer extends AbstractWebApplicationInitializer {
}

@Configuration (来自webapp基础)：

@Configuration
@EnableTransactionManagement
public class TransactionConfiguration {
    @Bean
    public DataSource dataSource() throws IOException {
        Properties conProps = PropertyUtil.getInstance().getProperties("jdbc");
        if (conProps.containsKey("url")) {
            DriverManagerDataSource dataSource = new DriverManagerDataSource(conProps.getProperty("url"), conProps);
            dataSource.setDriverClassName(conProps.getProperty("driverClassName"));
            return dataSource;
        }

        return null;
    }

    @Bean
    public SessionFactory sessionFactory() throws IOException {
        DataSource dataSource = dataSource();
        if (dataSource != null) {
            LocalSessionFactoryBuilder sessionBuilder = new LocalSessionFactoryBuilder(dataSource);
            sessionBuilder.scanPackages(PropertyUtil.getInstance().getPropertySplitTrimmed("hibernate", "packagesToScan"));
            sessionBuilder.addProperties(PropertyUtil.getInstance().getProperties("hibernate"));
            return sessionBuilder.buildSessionFactory();
        }

        return null;
    }

    @Bean
    public HibernateTransactionManager transactionManager() throws IOException {
        SessionFactory sessionFactory = sessionFactory();
        if (sessionFactory == null) {
            return null;
        }

        return new HibernateTransactionManager(sessionFactory);
    }
}

@Configuration (来自我的网络应用程序)：

@Configuration
public class MainConfiguration extends WebMvcConfigurerAdapter {
    @Autowired
    private PageViewInterceptor pageViewInterceptor; // Is annotated with @Component

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(pageViewInterceptor);
    }
}

@Service

@Service
public class PageViewServiceImpl implements PageViewService {
    @Autowired
    private PageViewDao pageViewDao;

    @Override
    public void savePageView(long ip, String visitPage, String userAgent) {
        PageView obj = new PageView();
        obj.setVisitDate(new Date());
        obj.setUserAgent(userAgent);
        obj.setPage(visitPage);
        obj.setIp(ip);

        pageViewDao.saveOrUpdate(obj);
    }
}

@Repository

@Repository
public class PageViewDaoImpl extends GenericDaoImpl<PageView, Long> implements PageViewDao {
    @Override
    public void saveOrUpdate(PageView obj) {
        if (!obj.isBot()) {
            super.saveOrUpdate(obj);
        }
    }
}

public abstract class GenericDaoImpl<T extends Identifier<I>, I extends Serializable> implements GenericDao<T, I> {
    @Autowired
    private SessionFactory sessionFactory;

    public SessionFactory getSessionFactory() {
        if (sessionFactory == null) {
            throw new IllegalStateException("SessionFactory has not been set on DAO before usage");
        }

        return sessionFactory;
    }

    @Transactional
    public void saveOrUpdate(T obj) {
        getSessionFactory().getCurrentSession().saveOrUpdate(obj);
    }
}

然后我会自动使用PageViewService并使用它的方法。

我知道这里有几个同样的问题，但我已经查过了：

Could not obtain transaction-synchronized Session for current thread

提供了@EnableTransactionManagement
服务将作为接口自动处理。

HibernateException: Could not obtain transaction-synchronized Session for current thread

检查是否在任何地方使用@Transactional，我使用getSessionFactory().getCurrentSession()

Spring Hibernate - Could not obtain transaction-synchronized Session for current thread

提供了@EnableTransactionManagement
检查是否在任何地方使用@Transactional，我使用getSessionFactory().getCurrentSession()

org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread

没有有用的答案。我要对所有组件进行扫描，而不仅仅是控制器。

java

spring

hibernate

orm

transactions

查看您的日志，我可以立即判断您的事务设置设置错误。这是因为您的堆栈跟踪中没有TransactionInterceptor调用。

当web控制器调用实际的服务方法时，Service代理会调用TransactionInterceptor。

确保使用Spring hibernate4类： org.springframework.orm.hibernate4.HibernateTransactionManager
不要覆盖@Transactional方法，而是使用模板模式。
尝试使用JPATransactionManager代替，这样您就可以用@PersistenceContext注释注入当前的EntityManager。这比在每个DAO方法中调用sessionFactory.getCurrentSession()要优雅得多。

您必须将@Transactional用于@Service和@Repository。它允许Spring应用并创建具有事务支持的代理。

在您的代码中，@Service类在类级别或方法级别上都没有@Transacional。

第二

实现WebApplicationInitializer的类在哪里？我看你在扩展一门课。总之，我的观点是，这里有如下内容：

@Override
public void onStartup(ServletContext container) {
    // Create the 'root' Spring application context
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
    rootContext.register(CentralServerConfigurationEntryPoint.class);

    // Manage the lifecycle of the root application context
    container.addListener(new ContextLoaderListener(rootContext));

    // Create the dispatcher servlet's Spring application context
    AnnotationConfigWebApplicationContext dispatcherServlet = new AnnotationConfigWebApplicationContext();
    dispatcherServlet.register(CentralWebConfigurationEntryPoint.class);

    // Register and map the dispatcher servlet
    ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherServlet));
    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("/");

}

其中CentralServerConfigurationEntryPoint.class必须只扫描必须在服务器端工作的组件(@Service、@Repository、事务处理的@Configuration、Hibernate、DataSource等)

其中，CentralWebConfigurationEntryPoint必须只扫描必须在客户机/web端工作的组件(@Controller、Formatters的@Configuration、Tiles、转换器等)

我不明白你的代码

@Override
protected WebApplicationContext createRootApplicationContext() {
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();

    ConfigurableEnvironment environment = rootContext.getEnvironment();
    environment.setDefaultProfiles("production");

    PropertyUtil propertyUtil = PropertyUtil.getInstance(environment.getActiveProfiles());
    String[] basePackages = propertyUtil.getPropertySplitTrimmed("webapp", "basePackages");
    rootContext.scan(basePackages);

    return rootContext;
}

@Override
protected WebApplicationContext createServletApplicationContext() {
    return new AnnotationConfigWebApplicationContext();
}

我的观点是:您的必须有两个AnnotationConfigWebApplicationContext，一个用于服务器和web端。

简单地回答这个问题id，您只需在dao类中使用@Trans显式，将配置类标记为@EnableTransactionManagement，并创建一个bean

**@Bean
public PlatformTransactionManager transactionManager() {
    DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource());
    return transactionManager;
}**

在这里，如果您看到EnableTransactionManagement注释中可用的代码示例，建议使用DataSourceTransactionManager而不是HibernateTransactionManager。
