Problems solved by technology

AMS2003, pages 168-77)) The recovery method based on restart technology proposed in this article, however, the method proposed in the JAGR article requires modification of the jboss server (an open source J2EE application server), and is only suitable for deployment in jboss The java application program of the server is valid, which makes it not universally applicable. In addition, this recovery method only uses the restart technology to restore the system, and the restart also depends on the characteristics of the jboss server. A single recovery method cannot solve hard failures such as file loss or malicious modification, which are very common for today's web systems

Embodiment Construction

[0034] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0035] combine figure 2 , the workflow of the hierarchical self-recovery method for Web systems under the MVC architecture of the present invention is as follows:

[0036] (1) Divide the self-recovery level of the target system into user request level, component call level and component internal service level from high to low;

[0037] (2) In the control layer of the target system, that is, the C layer, establish a request controller, one or more plug-in controllers, and a failure analysis and decision maker;

[0038] (3) In the model layer of the target system, that is, the M layer, a restart controller is established for each internal sub-component of the business logic processing component, so that these business logic processing components become self-recoverable components, and each business logic processing component The logical processing component respe...

Abstract

The invention provides a grading self-recovering method for a Web system under an MVC (model visual controller) framework. A 'fault generation point' which has the biggest possibility of failing in the system is mainly concentrated on service logic processing assemblies with complex functions; different recovery modes are utilized to recover the system step by step from low to high: restarting child components, hot-plugging service logic processing assemblies and resending the user requirement. If the recovery mode of low grade can solve faults, a high-grade recovery mode is not needed, or a higher-grade recovery mode is adopted for processing faults. For each recovery grade, the higher the grade is, the higher the recovery cost is, but the stronger the recovery ability is. The method has the advantages of shortening recovery time, lowering recovery cost and strengthening the safety and the survivability of the Web system under the MVC framework.

Description

technical field [0001] The invention relates to a self-recovery method of a Web system. Background technique [0002] Web systems play an important role in network applications, from finance to entertainment, from education to administration, Web systems serve people's work and life, and make people's work more convenient and efficient and their lives more colorful with its powerful functions . However, as the Web system is more and more relied on by people, its security and survivability are also undergoing severe tests. On the one hand, the structure of the Web system is becoming more and more complex due to the enhancement of its own functions. On the one hand, it is due to hackers' attacks on the Web system. Because the potential threats to the Web system brought by these security risks are almost inevitable, but people's requirements for the safe operation of the Web system have not been lowered. Therefore, how to quickly recover the Web system from failures has becom...
