Question

我的问题隐藏在课堂上，有两种方法。

@Repository
@Transactional(isolation = Isolation.READ_COMMITTED)
public class RetentionController {
    @Autowired
    private SessionFactory sessionFactory;
        ...

    @Transactional(readOnly = true)
    public BaseResource getResource(String pPath)throws ResourceNotFoundException{
        ...
        Criteria critDirExists = sessionFactory.getCurrentSession().createCriteria(Directory.class);
        critDirExists.add(Restrictions.eq(PATH, pPath));
        Directory dir = (Directory) critDirExists.uniqueResult();

        ...processing results...
    }

    @Transactional(readOnly = false)
    public void addDirectory(String pPath) {

        modelValidator.validateDirectoryURI(pPath);

        //check if such exists
        Criteria critExists = sessionFactory.getCurrentSession().createCriteria(Directory.class);
        critExists.add(Restrictions.eq("path", pPath));
        ...
     }

...
}

正确注入SessionFactory - 第一个方法正常执行。问题是： addDirectory在“Criteria critExists = sessionFactory.getCurrentSession（）。createCriteria（Directory.class）;”中抛出“没有Hibernate会话绑定到线程”，在“getResource（）”方法之后调用它。

日志（我添加标记以查看方法的开始和结束位置：GET RESOURCE：START / END，ADD DIRECTORY：START / END）：

Answer 1

解决方案是 - 添加到web.xml：

<filter>
  <filter-name>hibernateFilter</filter-name>
  <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>


<filter-mapping>
  <filter-name>hibernateFilter</filter-name>
  <url-pattern>/*</url-pattern> 
</filter-mapping>

此异常消失后。

Answer 2

我认为您需要将addDirectory方法的@Transactional设置更改为以下内容：

@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)

基于我对Spring / Hibernate中事务管理过程如何工作的理解，您当前的设置告诉hibernate您将以只读方式执行所有内容，因此当您尝试以非只读方式执行时它爆炸了。我在http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/transaction.html#tx-propagation

找到了相关的支持文档

我假设如果你在getResource之前调用你的addDirectory方法，那么你的代码就可以了。

Answer 3

如果Hibernate的版本在类属性中没有完全对齐，就会发生这种情况。

transactionManager类org.springframework.orm.hibernate X 必须与SessionFactory类org.springframework.orm.hibernate X 版本匹配，这也需要得到您在maven依赖中使用的版本。

“没有Hibernate会话绑定到线程”，事务方法会中断下一个事务的执行
