Specific embodiment

The present invention is a kind of ticket reselling website background management system framework, using four layer architectures, including presentation layer, control layer, Business Logic, data access layer, presentation layer are in client, and control layer, Business Logic, data access layer are in service Device end, uses medium of the Model as data interaction between each layer, the presentation layer using ExtJS frame realization interface display, The control layer receives user in the various requests of boundary layer and passs on to next layer of progress business logic processing, and will be last Processing result returns to presentation layer, and the Business Logic BLL is various by realizing method processing system defined in IBLL interface Service logic, when need to call database, then by factory mode DALFactory creation class call method access interface IDAL, then Interface is instantiated by data access layer DAL, realizes the operation to database, the data access layer incorporates Nhibernate frame Frame realizes data persistence, and by all deployment of components in a kind of spring.NET frame towards tangent plane programming, carries out Management, executes maintenance.

It shows bed boundary integral layout and designs the ExtJS frame based on JavaScript, system interface realizes that selection is common Border layout, interface is divided into five parts east, south, west, north, center, in its items specify make It is that its daughter element specifies specific location with region parameter, wherein the region center must use, and the region center can be certainly The remaining space in the dynamic other regions of filling, ExtJS is also very practical to the design of list, and basic verification mode such as phone number is No is sky, character, number etc., has the prompting mode of hommization, list uses parallel arrangement, sets layout attribute to Column, form controls are divided into 5 column, specify in the items of formpanel, columnWidth is arranged in each column, specify The percentage of overall width shared by the column, then the input control in the itemsi of each column, each control is specified by xtype Then type is arranged the configuration items such as allowbank, xtype, facilitates and complete data detection, if setting allowbank attribute is False just will appear miscue letter then frame will be displayed in red when mouse removes the control when mouse moves on control Breath, this prompting mode user are easier to receive, and the user experience is improved, when realizing system presentation layer using ExtJS frame, adopts Data submission is carried out with following two ways: 1. being submitted using list, it does not need to obtain form controls contents value one by one, but Disposably the value of all value i.e. the entire form is submitted into background server together, improves response speed, 2. pass through Ajax technology submits data to server, and the parameter that need to be submitted is placed in params with the format of name:value, realizes net Page asynchronous refresh, Business Logic is the core in entire Web system, be located at controller under data access layer it On, in general, controller calls service logic interface layer, the methods of deletion, preservation, update are defined in service logic interface layer, Business Logic inherits IBLL base class, and realizes method therein, completes the processing of every complicated business, and ticket reselling website business is patrolled It collects layer and mainly realizes returned ticket business processing, message reply, statistical classification and report generation etc., in addition, integrating spring.NET The effect of frame is mainly reflected in the management to Business Logic and provides integrated support to Nhibernete, is held by loC Device is grouped together the various components of dispersion, and controller is coupled with service logic interface layer, and controller receives The dependence of spring.NETloC container is injected, and is avoided controller from actively passing through the business logic components that new obtains its needs, is made Controller and business logic components loose coupling, business logic components depend on DAL, are responsible for by spring.NET container by DAL group Part is injected into business logic components, the loose coupling of realization business logic components and DAL inter-module, in system, spring.NET It is responsible for managing and assemble all Object, such as DAL class, service logic class, controller class using DI, between each layer object Dependence is injected by the dependence of spring.NET to be realized, spring.NET is injected using setter method, that is, is existed BLL object needed for being created in Controller controller class, and setter/getter method, creation are added for the object The work of Object example is no longer completed by caller, but carries out unified pipe by realization class of the spring.NET container to each layer Reason, reduces the degree of coupling between each component, improves the reusability of code, and data access layer DAL is responsible for handing over database Mutually, it is located under Business Logic, as BLL data access interface layer IDAL, class is created by factory mode DALfactory Call method, then method defined in IDAL is realized as DAL, the operation of database, IDAL interface layer introduces Nhibernate object/relational mapping tool, data are transmitted in the form of object, without paying close attention to underlying database It is SQLserver or Oracle or other types of database, completes Nhibernate configuration, establishes the work such as mapped file Afterwards, it reuses spring.NET to integrate Nhibernate, HibernateTemplate is arranged by configuration file and is used SessionFactory, so that it may use function find(), sace(), delete(), saveOrUpdate() etc. carry out operand According to library, this makes developer simpler using Nhibernate in spring.NET.

There are one define in the process of development: in the case of relatively simple for single table handling service logic, using The handling function of Nhibernate carrys out operating database；And when logic is relative complex, affairs are more, then using database Storing process solves, and advantage of this is that only need to be in database update storing process when project logic changes Can, do not have to update code logic.

The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
