Wherein the Spring frame comprises the following modules: a core container, a Spring context, a Spring AOP, a Spring DAOSprinORM, a pringWeb module, and a springMVC framework.

The Spring framework is an open-source lightweight JavaEE application program framework, provides a simple development mode through realizing reversal control, provides a consistency method for effectively managing and organizing business objects, encourages a good habit of programming interfaces instead of class programming, and reduces the coupling degree between components, so that unit testing and integrated testing are more beneficial to being developed.

The functions and features of the Spring framework are well organized in seven modules, Spring AOP, Spring ORM, Spring Web, Spring DAO, Spring Context, Spring WebMVC, Spring core, etc. Spring supports reusable service and Data Access Objects (DAOs) that can be reused across different J2EE environments (Web or EJB), standalone applications, test environments.

Each of the modules (or components) that make up the Spring framework may exist alone or in combination with one or more other modules. The function of each module is as follows:

a core container: the core container provides the basic function of the Spring frame. The main component of the core container is the beans factory, which is a factory-mode implementation. BeanFactory uses a control reversal (IOC) mode to separate the configuration and dependency specifications of an application from the actual application code.

Spring context: the Spring context is a configuration file that provides context information to the Spring framework. Spring context includes enterprise services such as JNDLEJB, email, internationalization, check and scheduling functions.

Spring AOP: by configuring the management features, the SpringAOP module directly integrates aspect-oriented programming functionality into the Spring framework. Therefore, any object managed by the Spring framework can be easily made to support the aopopspringaop module to provide the transaction management service for the object in the Spring-based application. By using SpringAOP, declarative transaction management can be integrated into an application without relying on an EJB component.

SpringDAO: the JDBCDAO abstraction layer provides a meaningful exception hierarchy that may be used to manage exception handling and error messages thrown by different database vendors. The exception hierarchy simplifies error handling and greatly reduces the amount of exception code that needs to be written (e.g., open and close connections). JDBC-oriented exceptions to SpringDAO follow a generic DAO exception hierarchy.

SpringORM: the Spring frame is inserted into a plurality of ORM frames, thereby providing an object relation tool of ORM, including JDO, Hibernate and iBatis SQLMap. All of which follow the Spring's generic transaction and DAO exception hierarchy.

A SpringWeb module: the Web context module is built on the application context module and provides context for Web-based applications. Therefore, the Spring framework supports integration with jakartas.

Spring mvc framework: the MVC framework is a fully functional MVC implementation that builds Web applications. Through the policy interface, the MVC framework becomes highly configurable, and MVC accommodates a large number of view technologies.

The J2EE application server comprises a control layer, a service logic layer and a data persistence layer, wherein the control layer is responsible for receiving a visitor request submitted by the presentation layer and calling the service layer to process the service logic; the business logic layer receives the call from the control layer and calls the operation database of the persistence layer; the data persistence layer is responsible for receiving the call of the service layer and completing specific data access operation, and the data access operation comprises a data processing code and a data storage code. The data persistence layer mainly comprises data access services and is responsible for communication with the database.

And the control layer is responsible for receiving the visitor request submitted by the presentation layer and calling the business layer to process the business logic. There may be different controllers for a particular business process. The control layer of the system is realized by adopting an MVC module of a Spring framework.

And the business logic layer receives the call from the control layer and calls the persistent layer operation database. The business logic layer interacts with the database through the data persistence layer, which encapsulates all business logic processes. The business logic layer contains business rule processing codes, namely algorithms, business rules and the like related to the business in the program. This layer is used to execute business processes and to formulate business rules for the data. The business logic layer is mainly oriented to business application and provides business service for the presentation layer. The service logic layer of the system is realized by adopting an AOP module of a Spring framework.

And the data persistence layer is responsible for receiving the call of the service layer and finishing specific data access operation and comprises a data processing code and a data storage code. The data persistence layer mainly comprises data access services and is responsible for communication with the database. The data persistence layer of the present system is implemented by Hibernate.

The bottom level is a relational database management system running on a database server.

The application of the Spring framework separates a service layer in a J2EE three-layer structure into a service logic layer and a data persistence layer, the service logic layer is handed to Spring processing, and a data access layer is handed to Hibernate processing, so that the hierarchical structure is particularly clear, and the maintenance and the expansion of a system are facilitated. In particular, Spring frames have the following advantages:

the method has the advantages that powerful configuration management based on JavaBeans and adopting a control inversion (I ℃) principle enables the construction of application programs to be faster and simpler.

(2) A core Bean factory that can be used in different operating environments from applets to java ee.

The generalized abstract layer of the database transaction allows a declaration type (declaration) transaction manager, and simplifies the division of the transaction to make the division independent of the bottom layer.

The built-in generalized policy for JTA and a single JDBC data source makes the transactional support for Spring do not require a java ee environment, as opposed to the generic JTA or EJBCMT.

The JDBC abstraction layer provides a targeted exception level (original codes are not extracted from SQL exceptions any more), simplifies error handling, and greatly reduces the amount of code for programmers. When using JDBC again, you do not need to write out another' terminate (final) module. And JDBC-oriented exceptions are consistent with a Spring universal data access object (DataAccessObject) exception level.

Integrated with Hibernate, JDO and ibaiss qlmaps in the form of resource containers, DAO implementation and transaction policies. The method utilizes a plurality of turning control convenience characteristics to fully support, and solves a plurality of typical Hibernate integration problems. All of these comply with Spring generic transaction and generic data access object exception level specifications.

A flexible core Spring function based MVC web application framework. The developer will have a high degree of control over the framework through the policy interface, and thus the framework will be adaptable to a variety of rendering (View) technologies, such as JSP, FreeMarker, Velocity, Tiles, iText, and POL-it is noted that the Spring middle layer can be easily incorporated into any MVC framework-based web page layer, such as Struts, WebWork, or Tapestry, to provide an aspect-oriented programming framework for services such as transaction management.
