HTTP状态500 - 请求处理失败;嵌套异常是org.hibernate.HibernateException：没有Hibernate Session绑定到线程 [英] HTTP Status 500 - Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread

问题描述

我写测试弹簧应用程序。我有问题。

我的java代码：
$ b $ p

控制器方法

  @RequestMapping（value =/ index）
 public String setupForm（）
 {
 mainService .getAllRecords（））; 
} 
  

服务界面

  @Transactional 
 public interface MainService 
 {
 
 public List< Record> getAllRecords（）; 
} 
  

服务impl

<$
@Autowired
private MainDao mainDao ;


@Transactional
public List< Record> getAllRecords（）
{

return mainDao.getAllRecords（）;
}

}

dao不标记为@

我看到下一个错误：

  HTTP状态500  - 请求处理失败;嵌套的异常是org.hibernate.HibernateException：没有Hibernate Session绑定到线程，并且配置不允许创建非事务性的一个在这里
  

如果我将dao接口标记为@Transactional，则效果很好。

配置：

我不明白这个问题的原因。

你能帮我吗？

解决方案

在你的web.xml中，你缺少声明Hibernate OpenSessionInViewFilter， hibernate session在您的请求过程中打开：

 < filter> 
< filter-name> hibernateFilter< / filter-name> 
< filter-class> org.springframework.orm.hibernate4.support.OpenSessionInViewFilter< / filter-class> 
< init-param> 
< param-name> singleSession< / param-name> 
< param-value> true< /参数值> 
< / init-param> 
< / filter> 
< filter-mapping> 
< filter-name> hibernateFilter< / filter-name> 
< url-pattern> / *< / url-pattern> 
< / filter-mapping> 
  

这可以解决您的错误。
请注意，过滤器类是针对Hibernate4的，您需要修复以防Hibernate3

I write test spring application. I have problem.

my java code:

controller method

    @RequestMapping(value = "/index")
    public String setupForm()
    {    
        mainService.getAllRecords());
    }

service interface

@Transactional
public interface MainService
{

    public List<Record> getAllRecords();
}

service impl

@Service("mainService")
@Transactional
public class MainServiceImpl implements MainService
{
    @Autowired
    private MainDao mainDao;


    @Transactional
    public List<Record> getAllRecords()
    {

        return mainDao.getAllRecords();
    }

}

dao doesn't mark as @Transactional.

I see next error:

HTTP Status 500 - Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

If I mark dao interface as @Transactional - it works good.

Configuration:

web.xml

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/root-context.xml</param-value>

I don't understand cause of this problem.

can you help me?

解决方案

In your web.xml you are missing to declare Hibernate OpenSessionInViewFilter, that provides your hibernate session to be open within your request process:

<filter>
        <filter-name>hibernateFilter</filter-name>
        <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
        <init-param>
            <param-name>singleSession</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>hibernateFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

This should fix your error. Please note that the filter class is for Hibernate4, you need to fix in case of Hibernate3
