Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of main steps of a log printing method according to an embodiment of the present invention. As an embodiment of the present invention, as shown in fig. 1, the main steps of the log printing method may include:
step S101, receiving a log printing request, acquiring a target scene according to the log printing request, and inquiring log configuration data corresponding to the target scene according to a scene identifier of the target scene;
step S102, judging whether the log level corresponding to the target scene is higher than the log level of the printing log code corresponding to the target scene;
step S103, if yes, determining that the log does not need to be printed;
and step S104, if not, acquiring a log printing instance corresponding to the target scene according to the log configuration data corresponding to the target scene, and then printing the log by using the log printing instance.
When a scene needs to be analyzed, a log of the scene may be printed so that the scene may be analyzed through the log of the scene. The target scene refers to a scene in which a log needs to be printed. After the target scene is acquired, the log configuration data corresponding to the target scene can be queried according to the scene identifier of the target scene. In addition, the scene identifier of the target scene may be placed into a transitibleth ready local, TTL for short, which is a component for solving the problem of context transfer during asynchronous execution, and the thread variable transfer function in the thread reuse scene is realized on the basis of the Inheritable thread local. The scene identification is put into the TTL, then the scene identification is obtained from the TTL, and then the log configuration data corresponding to the target scene is inquired according to the obtained scene identification, so that the problem of mixed dishes of the scene identification can be avoided, and the log can be printed according to the log configuration data corresponding to the target scene.
In step S101, log configuration data corresponding to the target scene may be queried according to the scene identifier of the target scene. Therefore, as an embodiment of the present invention, the log printing method may further include a process of configuring log configuration data corresponding to the scene for the scene, and the specific implementation method includes:
(1) a plurality of scenes is determined. If the detailed page of the commodity needs to display the freight rate, the scenario of calling the freight rate calculation interface is called, and then, the scenario of calling the freight rate calculation interface is called as an order system.
(2) And aiming at each scene, acquiring a scene identifier of each scene, configuring a log printing state, a log output mode and a log level corresponding to each scene, and acquiring log configuration data corresponding to each scene to obtain the log configuration data corresponding to a plurality of scenes. After a plurality of scenes are determined, for each scene, configuring log configuration data, specifically, acquiring a scene identifier of the scene, and configuring a log printing state, a log output mode and a log level for the scene according to actual requirements, so that the log configuration data corresponding to the scene can be obtained, that is, the log configuration data corresponding to the plurality of scenes can be obtained.
(3) And storing the log configuration data corresponding to the plurality of scenes into a memory or a database, wherein the target scene is a scene in the plurality of scenes. After the log configuration data is obtained, the log configuration data can be stored in a memory or a database, so that after a log printing request is received, the log configuration data corresponding to the target scene can be quickly inquired from the memory or the database according to the scene identifier of the target scene. In addition, if the log configuration data corresponding to a certain scenario needs to be changed, all application instances need to update the log configuration data in the memory or the database, for example, whether the log configuration data has a change can be queried through a timing task.
In another aspect, the log configuration data may include: log output mode and log level. The log output mode refers to outputting the log to a file, Kafka (i.e., an open source stream processing platform), Elasticsearch (i.e., a search server), or the like. The log level refers to the level of the log, for example, the log level is, from high to low: error, war, info, debug, trace. Where error indicates that while an error event occurs, it still does not affect the continued operation of the system, such as printing error and exception information, and this level may be used to avoid outputting too many logs; wan indicates that a potential error situation occurs, and some information is not error information but also gives some prompts; the info represents that the message emphasizes the running process of the application program on a coarse granularity level, such as printing some interesting or important information, which can be used for outputting some important information of the running of the program in a production environment, but can not be abused to avoid printing too many logs; debug points out that fine-grained information events are very helpful for debugging application programs and are mainly used for printing some running information in the development process; trace is a lower log level and is not generally used. Note that if the log level corresponding to the target scene is a certain level, it means that the log at the certain level and above is required to be printed. If the log level corresponding to the target scene is debug, the logs of error, war, info and debug levels need to be printed corresponding to the target scene.
The print log code refers to a code that needs to perform a print operation, for example, a certain system has 1000 codes, and 100 codes in the 1000 codes are codes that need to perform a log print operation. In the log printing method according to the embodiment of the present invention, the level of the log level corresponding to the target scene and the level of the log level of the print log code need to be analyzed. Specifically, after a scene code corresponding to a target scene is acquired, each print log code in the scene code needs to be analyzed according to the following method: judging whether the log level corresponding to the target scene is higher than the log level of the printing log code; if yes, skipping the printing log code, namely, not needing to print the log; if not, acquiring a log printing instance corresponding to the target scene according to the log configuration data corresponding to the target scene, and then printing the log by using the log printing instance. For example, the log level corresponding to the target scene is war, that is, the logs with the log levels of war and error in the target scene need to be printed, and if the log level of a certain printing log code is info, that is, the log level printed by the certain printing log code is info, the log corresponding to the certain printing log code does not need to be printed, so that the certain printing log code is directly skipped.
According to the log printing method, the log output mode and the log grade corresponding to the target scene can be inquired according to the scene identification of the target scene, then the log grade in the code is compared with the inquired log grade, and the log is printed by combining the inquired log output mode, so that the problems that the logs with different log grades cannot be printed according to different scenes and different output modes cannot be used in different scenes in the conventional log framework are solved, the log configuration data corresponding to the scene is used, the output mode and the printing grade of the log are dynamically controlled, different scene requirements can be met, the practicability is high, and the user experience is good.
The existing log framework has the following problems: logs can be printed in all scenes, and whether the logs are output or not can not be controlled in different scenes. For example, when the freight cost needs to be displayed on the commodity detail page, the freight cost calculation interface is called, and in the scene, the calling amount of the freight cost calculation interface is large and the recorded log significance is not large; and the log of the order system calling the freight calculation interface can be used as an important basis for subsequent freight calculation problem examination or data analysis. In order to solve the above problem, it is necessary to determine whether a scene has a requirement for printing a log for different scenes. Therefore, the log configuration data may include: log print status. And after querying log configuration data corresponding to the target scene, the log printing method may further include: judging whether the log printing state corresponding to the target scene is required to be printed or not; if yes, determining that the target scene needs to print the log, and then printing the log according to the log output mode and the log level corresponding to the target scene; if not, determining that the target scene does not need to print the log.
Fig. 2 is a schematic diagram of a main flow of a log printing method according to an embodiment of the present invention. As shown in fig. 2, the main flow of the log printing method may include:
step S201, receiving a log printing request, obtaining a target scene according to the log printing request, and querying log configuration data corresponding to the target scene according to a scene identifier of the target scene, where the log configuration data includes: log printing state, log output mode and log level;
step S202, judging whether the log printing state corresponding to the target scene is required to be printed, if so, executing step S203, otherwise, executing step S205;
step S203, judging whether the log level corresponding to the target scene is higher than the log level of the printing log code corresponding to the target scene, if so, executing step S206, otherwise, executing step S204;
step S204, acquiring a log printing instance corresponding to the target scene according to the log configuration data corresponding to the target scene, and then printing a log by using the log printing instance;
step S205, determining that the target scene does not need to print the log;
in step S206, it is determined that the print log code does not require a print log.
It should be noted that, in step S203, the log level corresponding to the target scene is compared with the log level of each print log code corresponding to the target scene, that is, whether each print log code needs to be printed is sequentially determined. For each printing log code, if the log needs to be printed, performing log printing according to step S204; if the log is not required to be printed, the log is not required to be printed according to the log printing code obtained in step S206, and then the next log printing code is skipped until all log printing codes are analyzed.
The log printing method provided by the embodiment of the invention can inquire the log printing state, the log output mode and the log grade corresponding to the target scene according to the scene identifier of the target scene, and then perform log printing according to the inquired log printing state, log output mode and log grade, so that the problems that whether logs are output or not can be controlled in different scenes, logs of different log grades can not be printed aiming at different scenes and different output modes can not be used in different scenes in the conventional log frame are solved, the situation that whether logs are printed or not can be dynamically controlled through log configuration data corresponding to the scenes, the output mode and the print grade of the logs can be dynamically controlled, different scene requirements can be met, the practicability is strong, and the user experience is good.
The existing log framework fixedly uses one or more output modes, so that different output modes used in different scenes cannot be realized. The log printing method provided by the embodiment of the invention can dynamically select the log output mode corresponding to the scene, so that log printing instances corresponding to different log output modes need to be generated, and the log printing instance corresponding to the log output mode can be called according to the log output mode corresponding to the target scene. Therefore, the log printing method of the embodiment of the invention can also comprise a process of generating a log printing instance, and the specific implementation method comprises the following steps:
(1) one or more log configurations are added to the configuration file of the log framework. For example, adding log configuration to the configuration file log4j2.xml of the log frame log4j2, and for example, adding log configuration to the configuration file log back. xml of the log frame log back.
(2) Setting a log output mode corresponding to log configuration for each log configuration, setting the log level corresponding to the log configuration as trace, generating a log printing instance corresponding to the log configuration, and storing the generated log printing instance by using Map; wherein, Key in Map is log output mode, Value is log printing example. That is to say, a logger configuration is newly added in a configuration file of the log frame, a log output mode corresponding to the logger configuration is set, and a log level corresponding to the logger configuration is set as trace, that is, the log level corresponding to the log configuration is set as the lowest level, so that a log print instance corresponding to the logger configuration can be generated. And, the log level corresponding to the log configuration is set to the lowest level, so that the generated log print instance can be used for printing logs of various log levels. And finally, storing the generated log printing instance into the Map, namely storing the generated log printing instance in a Key-Value data structure, wherein Key is a log output mode, and Value is a log printing instance, so that the log printing instance corresponding to the target scene can be inquired from the Map according to the log output mode corresponding to the target scene.
The existing log framework has the problem that logs with different log levels cannot be printed aiming at different scenes, and in order to solve the problem, the log printing method provided by the embodiment of the invention can print logs with different log levels through proxy classes. Therefore, the log printing method may further include: an agent class is defined, and a method for implementing log-level printing in the agent class is defined. That is, a proxy class is defined, and then for each log level, a method that can print the log at the log level in the proxy class is defined, such as a method that can print the log at the log level in the proxy class, such as error, war, info, debug, trace, and the like.
As an embodiment of the present invention, acquiring a log print instance corresponding to a target scene according to log configuration data corresponding to the target scene, and then performing log printing by using the log print instance, may include: screening a log printing example corresponding to the target scene from the Map according to a log output mode corresponding to the target scene; and calling a log level printing method corresponding to the target scene in the proxy class according to the log level corresponding to the target scene, and printing a log corresponding to the target scene according to a log printing instance corresponding to the target scene.
Specifically, the method for printing the log comprises the following steps: and screening out the log printing instance corresponding to the target scene from the Map for storing the log printing instance according to the log output mode corresponding to the target scene, calling a method for printing the log at the log level corresponding to the target scene in the proxy class according to the log level corresponding to the target scene, and printing the log corresponding to the scene according to the log printing instance corresponding to the target scene. That is, the journaling instance is executed in the proxy class.
It should be noted that, the log is printed to determine the actual code position, and if the log is printed corresponding to the 100 th code corresponding to the target scene, the actual code position is the 100 th code corresponding to the target scene. The specific code position determining process comprises the following steps: acquiring a current thread call stack, and traversing call stack elements; if the character string obtained by the getClassName method of the current stack element is the same as the name of the proxy class, and the character string obtained by the getClassName method of the next stack element in the stack is not the same as the name of the proxy class, the file name where the actual code is located and the number of lines where the actual code is located can be obtained from the getFileName method and the getLineNumber method of the next stack element.
