Memory optimization system and method based on jsf development framework

Abstract

The invention relates to a memory optimization system and method based on a JSF development framework. All manageable class objects in the system whose scope is the entire dialogue range inherit from the same parent class; the parent class includes a module for clearing management class objects, wherein the plurality of management class objects pass through the clearing The management class object module is connected with the parent class. The method includes: first step, all the manageable class objects with the scope of the entire dialogue are inherited from the same parent class; second step, in the initial loading of the management class objects with the scope of the entire dialogue, calling the structure of the parent class Function to remove other management class objects from the entire dialog. The present invention enables each dialog to retain only one instance of the management class object currently being called in a dialog process, which greatly reduces the memory requirement of the server; ensures that only one instance of the currently requesting class object is reserved in each dialog request ; Improve the response speed of WEB programs and the management performance in the server.

Description

【Technical field】 [0001] The invention relates to the field of WEB development by using a JSF (JavaServerFaces) framework, in particular to a memory optimization system and method based on the JSF development framework. 【Background technique】 [0002] With the release of J2EE1.5, JSF (JavaServerFaces) has become a standard framework for JAVA WEB development. JSF provides a component-centric user interface (UI) construction method, thus simplifying the development of JAVA server-side applications. . JSF introduces a component-based and event-driven development model, enabling developers to develop Web applications in a manner similar to the traditional interface. Provides a clean separation of behavior and expression. No special scripting language or markup language is used to connect UI components and Web layer. The technology provides a rich architecture for managing component state, processing component data, validating user input and manipulating events. However, in t...

However, in the development of large-scale application systems, the WEB server side of the JSF framework needs to manage a large number of management class objects as the scope of the entire conversation, so that as the conversation increases, a large number of class instances will be generated, and a large number of requests will be made during the entire conversation. A class object instance with a scope of the entire conversation will occupy a large amount of memory, which will put a lot of pressure on the server's memory and affect the response speed of the entire WEB
