我在尝试使用我的 @Service 带注释的类时遇到以下异常:

我初始化应用程序的方式很复杂，因此我需要提供完整基本代码的链接以获取更多信息:https://github.com/dtrunk90/webapp-base . 我将其用作 maven 叠加层。
这里是必要的代码:
初始化程序(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();
}
}
初始化程序(来 self 的 webapp):
public class WebApplicationInitializer extends AbstractWebApplicationInitializer {
}
@Configuration(来自 webapp-base):
@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 self 的 webapp):
@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 Autowiring PageViewService 并使用它的方法。
我知道这里有几个相同问题的问题，但我已经检查过任何东西:
Could not obtain transaction-synchronized Session for current thread
@EnableTransactionManagement已提供- 服务将作为接口(interface) Autowiring
HibernateException: Could not obtain transaction-synchronized Session for current thread
- 在我使用
getSessionFactory().getCurrentSession() 的所有地方检查
@Transactional
Spring Hibernate - Could not obtain transaction-synchronized Session for current thread
@EnableTransactionManagement已提供- 在我使用
getSessionFactory().getCurrentSession() 的所有地方检查
@Transactional
- 没有有用的答案。我希望对我的所有组件进行组件扫描，而不仅仅是 Controller
最佳答案
查看您的日志，我可以立即看出您的交易设置设置错误。那是因为您的堆栈跟踪中没有 TransactionInterceptor 调用。
TransactionInterceptor 在您的 Web Controller 调用实际 Service 方法时由 Spring Service 代理调用。
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。尝试改用
JPATransactionManager，这样您就可以使用@PersistenceContext注释来注入(inject)当前的EntityManager。这比在每个 DAO 方法中调用sessionFactory.getCurrentSession()要优雅得多。
关于java - hibernate 异常 : Couldn't obtain transaction-synchronized Session for current thread，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26562787/
