Problems solved by technology

However, most of the current J2EE persistence frameworks are not compatible with OSGi
There are also some teams working on the integration of some popular J2EE open source frameworks and OSGi, but their implementation styles are not uniform
In the component development process of enterprise-level persistence layers such as RFID middleware, it is often necessary to choose different persistence strategies, but due to the lack of support for a unified and efficient deployment model, it is quite difficult to switch between strategies
However, at present, the research on multi-access data strategy switching in the persistence layer is still in a blank stage

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] figure 1 Componentized system architecture diagram for SpringDM-based multi-persistence layer framework. In order to meet the needs of the RFID middleware for different access data strategies, multiple J2EE data access strategies should be integrated in the RFID middleware. The present invention integrates the framework Hibernate, iBatis and JDBC in the persistence layer implementation of the RFID middleware.

[0023] The multi-frame integration steps are as follows:

[0024] 1) Encapsulate the source code package of each framework into a Bundle, add the export package item in the Manifest file in the source code package, and expose the source code package of the framework;

[0025] 2) Package the database driver source code into a Bundle, and add an export package item to the Manifest file in the source code package to expose the core source code package of t...

Abstract

The invention provides a dynamic frame switching model based on SpringDM, which can deploy a plurality of data access strategies of a persistence layer on a dynamic model and provide persistence layer services for outsides in a mode of issuing SpringDM service. The dynamic model can randomly switch the plurality of data access strategies and can provide support for multi-frame OSGi (Open Scene Graphic) generalization as a general mode in which J2EE (Java 2 Enterprise Edition) persistence layer frame is deployed in the OSGi. The invention applies the dynamic model to realize the persistence layer of RFID (Radio Frequency Identification) middleware. Enterprise-level RFID middleware requires that the data persistence layer can be flexibly switched among the plurality of data access strategies so that the JDBC (Java Data Base Connectivity) of the data access strategies of the persistence layer and the data access frame Hibernate and iBatis of the persistence layer are simultaneously integrated on the OSGi frame, and the persistence layer services are provided for the RFID middleware in the mode of issuing the SpringDM service. The RFID middleware can realize that the data access strategies are randomly switched by selecting different services.

Description

technical field [0001] The invention relates to a J2EE persistence layer componentization method and its application, especially the application in the RFID middleware persistence layer. technical background [0002] The ideas and technologies of Component-Based Software Development (CBSD) and Service Oriented Architecture (SOA) have improved the degree of software reuse and the flexibility of design and deployment, and have become modern software engineering. A model that is highly advocated. The prior art has developed a reconfigurable RFID middleware based on the OSGi (Open Service Gateway Initiative) framework, in which the equipment management layer, application layer event processing layer, Web presentation layer and workflow engine of the RFID middleware have all been successfully completed. Component-based development realizes the goal of being customizable and reconfigurable for the core part of the RFID middleware and the presentation layer. [0003] In tradition...
