Struts2 is the WebWork upgrade, rather than an entirely new framework, therefore the stability, performance and other areas have a very good assurance: it absorbed the advantages of both Struts1 and WebWork, therefore, is a very worth the wait framework.Struts2 Action class can implement an Action interface and other interfaces can also be achieved to enable optional and custom services possible. Struts2 provides a ActionSupport to achieve mon base class interface. Action interface is not necessary, any POJO object execute identity can be used as an object Struts2 in Action. Struts2 Action object for each instance of a request to generate a, there is no threadsafety problems. (In fact, servlet containers generate many for each request can be discarded objects, and will not lead to performance and garbage collection issues). Struts2 Action does not depend on the container, allowing Action out of the container to be tested separately. If necessary, Struts2 Action can still access the original Request and Response, however, other elements to reduce or eliminate direct access to HttpServetRequest and HttpServletResponse necessary. Struts2 Action can be initialized, set properties, call methods to test, dependency injection support also makes testing easier. Struts2 using the Action attribute directly as input properties, eliminating the need for the second input object needs. Input properties may have their own (sub) attribute the rich object type. Action properties able to access web pages on the taglibs. Struts2 also supports the ActionForm pattern. rich object types, including business objects, can be used as input/output objects. This ModelDriven feature simplifies the taglib reference to the POJO input objects. Struts2 can use JSTL, but also supports a more powerful and flexible expression language Object Graph Notation Language (OGNL). Struts2 using the ValueStack technology, so that the value of taglib to access your pages without the need to (view) and object to bind together. ValueStack Strategy Yun3. Spring IntroductionSpring is an opensource framework, created by Rod Johnson. It is the development of enterprise applications in order to solve the hybrid nature of hair created. Spring using the basic JavaBean to plete before the EJB is only possible to plete things. However, Spring is not limited to the use of serverside development. From the simplicity, testability, and loose coupling point of view, any Java application can benefit from the Spring.Objective: To solve the plexity of enterprise application development.Function: Using the basic JavaBean to replace EJB, and provides additional functionality of enterprise applications.Range: Any Java application.4. Hibernate IntroductionHibernate is an open source objectrelational mapping framework, it conducted a lightweight JDBC object package so that Java programmers can use the objectoriented programming ideas to manipulate the database. Hibernate can use EJB in J2EE architecture to replace the CMP, to plete data persistence. It can be applied to any use of JDBC occasions, both in the Javaclient program useful, you can also Servlet / JSP in Web applications using theHibernate API is simple to learn, and it is the interaction with the program flow quite naturally. Call it in place, we can achieve this objective. It brings a lot of automation and codesaving benefits, so I spent a little time to learn it was worth it. But also get another benefit, that is, the code do not care to use the database type (otherwise even need to know). The pany where I once had in the development process later was forced to replace the database vendor experience. This will cause a huge disaster, but the help of Hibernate, simply modify the Hibernate configuration files.技術(shù)簡介1. MVC設(shè)計(jì)模式介紹MVC模式是“ModelViewcontroller”的縮寫，中文翻譯為”模式試圖控制器”。類似的，重要Controller改變了View，View會從潛在的Model中獲取數(shù)據(jù)來刷新自己。在J2EE模式目錄中，通常采用service to worker模式是新，而service to
