Embodiment Construction

[0020] The dynamic upgrade process of the Web business system based on the Java platform is the hot replacement process of the Java class files running in the Web business system. In the embodiment of the present invention, the class loading method is rewritten, that is, the loading of the Java class files is redefined. method to realize the dynamic loading of Java class files (such as Jar packages), specifically: create a custom class loader, make the newly created class loader inherit the specified parent class loader, and set the parent class loader to is an empty value, then use the new class loader to load at least one Java class file in the preset storage location, and use the class loader after loading the Java class file to replace the loaded class loader specified in the Java platform kernel.

[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] In the Web business system based...

Abstract

The invention relates to the field of computers, and discloses a method and a device for dynamically upgrading a Web service system based on a Java platform, which are used for realizing dynamic upgrading of the Web service system on the premise of not interrupting a Web service. The method comprises the following steps of: loading a Java-class file at an appointed position by adopting a self-defined class loader; and replacing an appointed class loader in a Java platform core by adopting the class loader in which the Java-class file is loaded. Thus, an original Java-class file can be directly replaced by adopting an upgraded Java-class file to realize the dynamic upgrading of the Web service system without restarting a Web server or interrupting the Web service. Therefore, the continuity of the Web service is ensured, the performance and the service quality of the Web service system are improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for dynamically upgrading a Java platform-based Web service system. Background technique [0002] With the continuous updating of Web technology, Web business systems based on different architectures emerge in endlessly. Due to the cross-platform advantages of the Java language, the application of J2EE-based Web business systems is more extensive, covering almost all walks of life, such as the telecommunications industry, the financial industry, etc. Wait. Frequent changes in business requirements usually require 24-hour uninterrupted service of the Web business system. When the system is upgraded, the Web business system needs to be stopped, which will inevitably interrupt the business operations of current users and affect the normal operation of the Web business system. will have a certain impact. [0003] In view of such drawbacks and limitations, it is necessar...
