Log printing method and device and log printing system

Abstract

The invention discloses a log printing method and device and a log printing system. The log printing method is used in a business system, and the business system comprises multiple layers. The method comprises the steps of receiving a business request; determining a corresponding layer and a corresponding log printing component according to the business request; adopting the determined log printing component to print log information generated in the layer corresponding to the business request into a log file. According to the method, a log framework which is simple, flexible, and does not invade a business code is built, the business system does not need to add codes, when requests from different business come, the log framework built through the method prints parameters of each layer processing method and returning values to log files corresponding to different business; meanwhile, log print in business codes can also be directly printed into the log files corresponding to the business, and thus all the logs in a business request link can be printed in the same file at one time.

Description

technical field [0001] The present application relates to the technical field of server-end business printing, and in particular to a log printing method. The present application also relates to a log printing device and system. Background technique [0002] In server-side business systems, different levels are often divided for code isolation and abstraction. A simple back-end business system can be divided into service layer, domain layer, and data layer. Such a front-end request will be processed through three layers of the back-end business system. The traditional method will be manually implemented in the code of each implementation class in each layer. Designate a logger to print logs, which is not flexible enough to print logs, the code is repeated, and the log string of a business request link cannot be written in a file, which leads to time-consuming and labor-intensive troubleshooting and business monitoring, wasting a lot of resources. [0003] Or, the business ...

AI Technical Summary

Problems solved by technology

The final printed log of a business request is scattered in multiple files. It is very inconvenient to check the log by grep multiple files to view the complete link.

In addition, because multiple business logs are printed in the same file, the monitoring of configuration business puts a lot of pressure on the performance of the monitoring system.

[0004] Therefore, the existing technology cannot well achieve the effect of printing all the logs on the link of a business request to a file. Even if the above effect is achieved through a certain method, it is necessary to add additional codes in the business system to give the program The development of the developer's business code causes serious inconvenience
