java - hibernate 和 Spring : Exception when trying to create a transaction

标签 java spring hibernate maven hibernate-5.x

所以我第一次尝试使用 Spring 来管理 hibernate 事务，但出了点问题。我不确定是什么。我在这个网站上查看了一堆类似的答案，但我所看到的似乎都不是正确的。

所以，我将复制并粘贴一堆我的代码以及一些解释，并在这里寻求帮助。

这是我得到的异常的堆栈跟踪。本质上，它似乎正在尝试找到 org.hibernate.engine.transaction.spi.transactioncontext，并且无法。

异常堆栈跟踪

现在，我搜索了这个站点，我看到的最重要的事情是，这意味着我的 pom.xml 中有一个错误的依赖项。问题是，我的 pom.xml 中有最新版本的 hibernate-core 依赖项。根据我的阅读，这就是我这门课所需要的。

另外，我正在调用的 DAO 中添加实际方法。此方法是在抛出异常时尝试运行的方法。

DAO 方法:

@Transactional
@Override
@SuppressWarnings("unchecked") //hibernate list() method doesn't support generics
public List<String> getSavedPortfolios() throws HibernateException {
    List<String> portfolioNames = new ArrayList<>();

    List<SQLPortfolioModel> portfolioList = sessionFactory.getCurrentSession()
                                .createCriteria(PortfolioModel.class)
                                .list();

    for(SQLPortfolioModel portfolio : portfolioList){
        int id = portfolio.getUserID();
        String name = portfolio.getPortfolioName();
        BigDecimal netWorth = portfolio.getNetWorth();
        Calendar timestamp = portfolio.getTimestamp();

        String fileName = String.format("%1$d-%2$s-%3$s-"
                +"%4$s", id, name, moneyFormat.format(netWorth), 
                timestampFormat.format(timestamp.getTime()));
        portfolioNames.add(fileName);
    }

    return portfolioNames;
}

最后，这是我的 spring-context-data.xml。它包含我的 spring 数据 bean 的所有配置，以及事务的东西:

</bean>

 </beans>

所以我只是不知道为什么会这样。我已经两次和三次检查了我所做的与我在网上看到的内容，我看不到错误。这是我第一次尝试使用 Spring 事务管理。任何帮助将不胜感激。

PS。我正在同时使用 Spring 4 和 Hibernate 5，如果这会有所不同的话。

最佳答案

在您的 POM 中，您依赖于 Hibernate 5，但在您的事务管理器中，您使用的是 Hibernate 4。

更改您的事务管理器以匹配您的 pom(即从 hibernate4 到 hibernate5):

<bean id="transactionManager"
        class="org.springframework.orm.hibernate5.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
</bean>

如果这导致找不到类错误，请将您的 spring 框架升级到 4.2.2
