The MVC mode divides application into three core ponents of Model, View and Controller. Struts is a realization of MVC. It is an open source Web application framework and uses Servlet and JSP marks that belong to the J2EE norm as a part of the realization. Struts inherits MVC characteristics and realizes some corresponding changes and extension according to J2EE traits. Struts separates Java codes of JSP by Java Bean and Action class to be the MVC mode, transmits data among the three partitions of Model, View and Controller, demonstrates the connection between various classes and JSP pages by configuration files finally and it intends to realize the separation of presentation layer, business layer and data layer. The Struts structure is shown in Figure 1. The Model contains the business logic that exchanges data with a persistence layer. The View is in charge of producing what is directly visible to the user, e. g. web pages. The Controller is the layer that receives requests from clients, determines what business logic takes place and where to go next. In the Struts framework, the Model uses Java classes for the business logic. The View can be implemented with JSP and the Tag lib of Struts. The Controller is a J2EE ponent known as Servlet, more specifically an ActionServlet object, which determines what or when logic gets executed and where the control should get directed. 2 Hibernate Framework Based on ORM Working with both the objectoriented software and the relational database is a plicated task with Java Database Connectivity (JDBC) because there is mismatch between how data is represented in objects versus relational database. So with JDBC, developers have to write pure the Structured Query Languag (SQL) statements to map an object model39??刂破鲗?,接收來自客戶端的請求,決定哪些業(yè)務(wù)邏輯需要的地方,下一站去哪里。它可以集成各種 Web 服務(wù)器或應(yīng)用服務(wù)器,幾乎支持所有流行的數(shù)據(jù)庫服務(wù)器。整合顯示了面向?qū)ο蟮乃枷?,充分解決了一些問題,在傳 統(tǒng)的 J2EE 以及對數(shù)據(jù)庫的操作。它可以接收來自客戶端程序和妥善處置后,將它們保存到存儲設(shè)備,數(shù)據(jù)存儲設(shè)備讀取數(shù)據(jù),然后將其發(fā)
