hibernate deleteall 问题

Question

我调用
HibernateTemplate
里面的 deleteall 
但 为什么  不处理  
下面 SQL 没有delete....
也没有报错
有什么办法 能查 那里出问题了吗？
我直接掉用　deleteall 方法　会　进行　处理
我复杂　调用的时候就　不会　处理　
也　不报错　。

Answer 1

代码  太多  了  
其实    就是 没提交  
我想问下  大概 什么原因  会产生 这个 问题
    public void testUpdateItemMapping(ItemMapping itemMapping){
        ItemMapping itemMappingInDataBase = itemMappingDAO.findById (itemMapping.getId ());
        Set<ItemMappingProps> itemMappingPropss = itemMapping.getItemMappingPropss ();
        Set<ItemMappingProps> itemMappingPropssInDataBase = itemMappingInDataBase.getItemMappingPropss ();
        List<ItemMappingProps> itemMappingPropsDelete = new ArrayList <ItemMappingProps>();
        List<ItemMappingProps> itemMappingPropsSaveOrUpdate = new ArrayList <ItemMappingProps>();
        if(itemMappingPropss.size () == 0 || itemMappingPropss == null){
            itemMappingPropsDelete.addAll (itemMappingPropssInDataBase);
        }else{
            for(ItemMappingProps itemMappingPropsInDataBase : itemMappingPropssInDataBase){
                boolean flag = false;
                Iterator<ItemMappingProps> it = itemMappingPropss.iterator();
                while(it.hasNext()){
                    ItemMappingProps itemMappingProps = it.next();
                    if(itemMappingProps.getId () == null || itemMappingProps.getId () == 0){
                        itemMappingPropsSaveOrUpdate.add (itemMappingProps);
                        it.remove ();
                        continue;
                    }
                    if(itemMappingProps.getId ().intValue () == itemMappingPropsInDataBase.getId ().intValue ()){
                        itemMappingPropsSaveOrUpdate.add (itemMappingProps);
                        it.remove ();
                        flag = true;
                        break;
                    }
                 }
                if(!flag){
                    itemMappingPropsDelete.add (itemMappingPropsInDataBase);
                }
            }
        }
        itemMappingDAO.clear ();
        itemMappingPropsDAO.deleteAll (itemMappingPropsDelete);
//        itemMappingPropsDAO.saveOrUpdateAll (itemMappingPropsSaveOrUpdate);
    }
    
    public void testUpdateItem(Item item){
        Item itemInDataBase = itemDAO.findById (item.getId ());
        Set<ItemMapping> itemMappings = item.getItemMappings ();
        Set<ItemMapping> itemMappingsInDataBase = itemInDataBase.getItemMappings ();
        List<ItemMapping> itemMappingDelete = new ArrayList <ItemMapping>();
        List<ItemMapping> itemMappingSaveOrUpdate = new ArrayList <ItemMapping>();
        if(itemMappings == null || itemMappings.size () == 0 ){
            itemMappingDelete.addAll (itemMappingsInDataBase);
        }else{
            for(ItemMapping itemMappingInDataBase : itemMappingsInDataBase){
                boolean flag = false;
                Iterator<ItemMapping> it = itemMappings.iterator();
                while(it.hasNext()){
                    ItemMapping itemMapping = it.next();
                    if(itemMapping.getId () == null || itemMapping.getId () == 0){
                        itemMappingSaveOrUpdate.add (itemMapping);
                        it.remove ();
                        continue;
                    }
                    if(itemMapping.getId ().intValue () == itemMappingInDataBase.getId ().intValue ()){
                        itemMappingSaveOrUpdate.add (itemMapping);
                        it.remove ();
                        flag = true;
                        testUpdateItemMapping(itemMapping);
                        break;
                    }
                 }
                if(!flag){
                    itemMappingDelete.add (itemMappingInDataBase);
                }
            }
        }
        itemDAO.clear ();
//        itemMappingDAO.deleteAll (itemMappingDelete);
//        itemMappingDAO.saveOrUpdateAll (itemMappingSaveOrUpdate);
    }
后面调用了   
public void deleteAll(List<ItemMappingProps> itemMappingsProps){
        getHibernateTemplate().deleteAll (itemMappingsProps);
    }对象 传过来了  但是   HIBERNATE   不处理  是什么原因

Answer 2

我再getHibernateTemplate().deleteAll (itemMappingsProps);
加了一句  这个 就行了 
getHibernateTemplate ().flush ();
那为什么不刷  会不执行呢 ？
有谁  能帮我解释下 

Answer 3

撒 意思   要看事务的配置 ？
