1.保存数据到数据库

	@DataResolver
    @Transactional
	public void saveCompany(Collection<SlCompany> slCompanys) {
		//修改，新建，移动就是save,删除为delete
		for(SlCompany o: slCompanys) {
			//从dorado前端传过来的数据可直接EntityUtils.getState(o)，否则先把o变成Entity
			//o = EntityUtils.toEntity(o);EntityUtils.setState(o, EntityState.MODIFIED);
			if(EntityState.DELETED.equals(EntityUtils.getState(o))){
				slCompanyDao.delete(o);
			}
			slCompanyDao.save(o);
		}
		//先查看各对象的状态，再进行处理
//		slCompanyDao.persistEntities(slCompanys);

//HibernateDao.persistEntities
@SuppressWarnings("unchecked")
public int persistEntities(Collection<T> entities) {
    int i = 0;
    for (Object entity : EntityUtils.getIterable(entities,
            FilterType.DELETED)) {
        delete((T) entity);
        i++;
    }
    for (Object entity : EntityUtils.getIterable(entities,
            FilterType.MODIFIED)) {
        save((T) entity);
        i++;
    }
    for (Object entity : EntityUtils
            .getIterable(entities, FilterType.MOVED)) {
        save((T) entity);
        i++;
    }
    for (Object entity : EntityUtils.getIterable(entities, FilterType.NEW)) {
        save((T) entity);
        i++;
    }
    return i;
}
//

//
	public static EntityState getState(Object entity)

			EnhanceableEntity enhanceableEntity = (EnhanceableEntity)entity;
			return enhanceableEntity.getEntityEnhancer();
		}
		//从dorado前端传过来的如果没有经过任何处理，是ProxyBeanUtils
		if (ProxyBeanUtils.isProxy(entity))
		{
			MethodInterceptorDispatcher dispatcher = ProxyBeanUtils.getMethodInterceptorDispatcher(entity);
			if (dispatcher != null)
			{
				org.aopalliance.intercept.MethodInterceptor mis[] = dispatcher.getSubMethodInterceptors();
				org.aopalliance.intercept.MethodInterceptor arr$[] = mis;
				int len$ = arr$.length;
				for (int i$ = 0; i$ < len$; i$++)
				{
					org.aopalliance.intercept.MethodInterceptor mi = arr$[i$];
					if (mi instanceof EntityEnhancer)
						return (EntityEnhancer)mi;
						//mi.getState()
				}

2.查找

slEmployeeDao.find(page, " from SlEmployee where 1=1 " + " AND name like '%li%' ");
