Java 在HandlerInterceptor上启用hibernate筛选器

我有如下hibernate筛选器：

@Entity
@FilterDef(name = "filter_name", parameters = { @ParamDef(name = "tenatId", type = "long") })
@Filter(name = "filter_name", condition = "tenant_id = :tenantId")
public class MyEntity {

   private long tenantId;

}

@Configuration
public class RequestInterceptor implements HandlerInterceptorAdapter {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
        Object handler) throws Exception {
        Filter filter = entityManager.unwrap(Session.class).enableFilter("filter_name");
        filter.setParameter("tenantId", myService.getTentantId());
    }
}

我想在每次请求出现时启用此过滤器，因此我创建请求拦截器，如下所示：

@Entity
@FilterDef(name = "filter_name", parameters = { @ParamDef(name = "tenatId", type = "long") })
@Filter(name = "filter_name", condition = "tenant_id = :tenantId")
public class MyEntity {

   private long tenantId;

}

@Configuration
public class RequestInterceptor implements HandlerInterceptorAdapter {

    @PersistenceContext
    private EntityManager entityManager;

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response,
        Object handler) throws Exception {
        Filter filter = entityManager.unwrap(Session.class).enableFilter("filter_name");
        filter.setParameter("tenantId", myService.getTentantId());
    }
}

但我无法访问事务管理器，出现错误：

...

如果我将代码移动到控制器，它会工作：

@RequestMapping(method = RequestMethod.GET, value = "/test")
public List<MyEntity> test() {
    Filter filter = entityManager.unwrap(Session.class).enableFilter("filter_name");
    filter.setParameter("tenantId", myService.getTentantId());
    return myService.findAll();
}

@RequestMapping（method=RequestMethod.GET，value=“/test”）
公共列表测试（）{
Filter Filter=entityManager.unwrap（Session.class）.enableFilter（“Filter_name”）；
setParameter（“tenantId”，myService.getTentantId（））；
返回myService.findAll（）；
}

你知道为什么我不能在拦截器中打开hibernate会话吗

欢迎任何建议，谢谢
