DDD领域模型数据访问权限（九）

权限分为：数据权限和功能权限

数据权限：

查询提供附加表达式的支持：

//提供附加表达式的支持
        List<TAggreateRoot> GetByCondition(Expression<Func<TAggreateRoot, bool>> condition,
        Expression<Func<TAggreateRoot,bool>> definecondition);
        //返回聚合根分页的方法
        List<TAggreateRoot> GetByConditionPages(Expression<Func<TAggreateRoot, bool>> condition,
            Expression<Func<TAggreateRoot, bool>> definecondition,

不需要查询条件的写法：　

 var query = orderdbcontext.Set<TAggreateRoot>().Where(condition.And(definecondition));
