我正在使用hibernate HPA构建Spring WebMVC UI背后的应用程序。拼图的每个部分都通过了单元测试，但我在将应用程序粘合在一起时遇到了麻烦。
看起来Hibernate事务策略阻止Hibernate参与事务。
到目前为止的研究： Hibernate默认配置了jta事务策略。
的假设是正在执行服务层上的@Transactional注释（我可以在日志中看到它）。正在从事务管理器中检索JDBC数据源。然后，当事务管理器尝试将JDBC数据源附加到事务时，它突然无法找到事务。我已经跟踪了代码，当Bitronix去寻找它时，交易就不存在了。
此问题的堆栈是：
以下是失败方法的代码：
@Service
public class ConfigPropertiesServiceImpl {
private Logger logger = LoggerFactory.getLogger(this.getClass());
@Autowired
private ConfigPropertiesSDO configPropertiesSDO;
@Autowired
private ConfigPropertiesDAO configPropertiesDAO;
@Transactional
public PropertyValue fetchPropertyValue (String key)
{
return configPropertiesSDO.fetchProperty(key);
}
}

这是我的Spring Context初始化：
public class AppInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext container) throws ServletException {
Logger logger = LoggerFactory.getLogger(this.getClass());
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(DatabaseConfig.class);
rootContext.refresh();
// Manage the lifecycle of the root appcontext
container.addListener(new ContextLoaderListener(rootContext));
container.setInitParameter("defaultHtmlEscape", "true");
AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
mvcContext.register(ViewConfig.class);
mvcContext.setServletContext(container);
ServletRegistration.Dynamic servlet = container.addServlet(
"dispatcher", new DispatcherServlet(mvcContext));
servlet.setLoadOnStartup(1);
Set<String> mappingConflicts = servlet.addMapping("/");
if (!mappingConflicts.isEmpty()) {
for (String s : mappingConflicts) {
logger.error("Mapping conflict: " + s);
}
throw new IllegalStateException(
"'appServlet' cannot be mapped to '/' under Tomcat versions <= 7.0.14");
}
}
}
...以及配置事务处理的数据库配置类...
@EnableTransactionManagement
@ComponentScan({ "com.myApp.svc.*","com.myApp.core.*","com.myApp.ui.*" })
@Configuration
public class DatabaseConfig {
@Bean(destroyMethod="shutdown")
public BitronixTransactionManager bitronixTransactionManager() {
btmConfig();
return new BitronixTransactionManager();
}
@Bean
public JtaTransactionManager transactionManager() {
JtaTransactionManager mgr = new JtaTransactionManager();
mgr.setTransactionManager(bitronixTransactionManager ());
mgr.setUserTransaction(bitronixTransactionManager ());
mgr.afterPropertiesSet();
return mgr;
}
@Bean
public TransactionTemplate transactionTemplate ()
{
return new TransactionTemplate (transactionManager());
}
@Bean(initMethod = "init", destroyMethod = "close")
public DataSource dataSource() {
PoolingDataSource dataSourceInstance = new PoolingDataSource();
dataSourceInstance.set ... ();
dataSourceInstance.init();
return dataSourceInstance;
}
@Bean
public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean()
throws IOException {
// The bean isn't created yet, but we need some of its functions
// This instance will be released as soon as the method goes out of
// scope
BitronixTransactionManager tm = bitronixTransactionManager();
PrivateDatastoreServiceImpl pds = new PrivateDatastoreServiceImpl();
pds.setPrivateDatastorePropertiesFile(privateDatastorePropertiesFile());
pds.init();
LocalContainerEntityManagerFactoryBean emf = null;
PrivateDatastoreConfigurationModel model = pds

有多个交互问题导致hibernate拒绝加入交易。
hibernate属性并不合适。如上所述，hibernate甚至没有尝试加入交易。最终的休眠配置是：
Properties props = new Properties();
props.setProperty(HIBERNATE_DIALECT, pds.getHibernateStrategy(model.getDbType()));
props.setProperty(HIBERNATE_DDL_AUTO, "false");
props.setProperty(HIBERNATE_SHOW_SQL, "false");
props.setProperty(HIBERNATE_FORMAT_SQL, "false");
props.setProperty("hibernate.transaction.jta.platform", org.hibernate.engine.transaction.jta.platform.internal.BitronixJtaPlatform.class.getName());
props.setProperty("hibernate.jndi.class", bitronix.tm.jndi.BitronixInitialContextFactory.class.getName());
props.setProperty("jta.UserTransaction", "BTMUserTransaction");
props.setProperty("jdbc.exclusive-connection.mode", "Transactional");
// JTA stuff
props.setProperty("hibernate.connection.release_mode","after_statement");
props.setProperty("hibernate.current_session_context_class","jta");
props.setProperty("hibernate.transaction.manager_lookup_class","org.hibernate.transaction.BTMTransactionManagerLookup");
bitronix事务管理器必须是单例。建立一个新的事务管理器，该bean应该被定义为：
@Bean(destroyMethod="shutdown")
public BitronixTransactionManager bitronixTransactionManager() {
btmConfig();
return TransactionManagerServices.getTransactionManager();
}
让两个交易经理浮动使问题混乱。
