In this embodiment, when the Java program runs, the log output apparatus listens to the running of the Java program to determine whether the currently running program of the Java program is a program of a connection point, that is, whether the position of the currently running program hits the position of log output, and if so, obtains the time and content of log output to generate and output a log subsequently, that is, generates and outputs a log in a manner of "log output position + time of log output + content of log output + listen".

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a log output method of a Java Web application according to another embodiment of the present disclosure.
As shown in fig. 2, the method includes:
s201: the software component model of Java for the wrapper of the output log is registered in the Spring framework of the Java Web application.
For example, the technical features of this embodiment that are the same as those of the above embodiment are not described in detail in this embodiment.
This step can be understood as: the log output apparatus configures a wrapper (LogWrapper) for log processing (such as log output in the present embodiment) in advance, registers the wrapper in the Spring framework to register the wrapper as a software component model (bean) of Java in the Spring framework.
S202: and monitoring the running Java program to obtain monitoring information.
For example, in conjunction with the above embodiments, the wrapper may listen to the running Java program to obtain the listening information.
In some embodiments, S202 may include the steps of:
the first step is as follows: and monitoring the running Java program by adopting the wrapper to obtain a monitored program segment, and redirecting the monitored program segment to obtain the position of the monitored program segment.
The second step is as follows: and if the monitored position of the program segment is the same as the log output position of the Java program indicated by the connection point, determining the monitored information as the information representing the program of the connection point in the monitored Java program.
Illustratively, the Java program includes multiple segments of programs, such as multiple segments of programs that constitute a Java program for implementing a business service. The wrapper may listen to each program segment and redirect each program segment to obtain the location of each program segment.
After monitoring the position of a program, the wrapper may match the position with the log output position of the Java program indicated by the connection point to determine whether the two are the same position, and if the two are the same position, the program segment is the program segment corresponding to the connection point.
In the embodiment, the wrapper monitors and determines the position of the program segment, and matches the monitored position with the log output position, so that when the monitored position is the same as the log output position, the output log is determined, and the accuracy and reliability of log output are improved.
S203: and if the monitoring information represents the program monitoring the connection point in the Java program, acquiring a notification corresponding to the connection point from a Spring framework of the Java Web application.
The connection point is used for indicating the preset position of the log output of the Java program, and the time and the content for indicating the log output are notified, and the connection point and the notification are configured in the Spring frame of the Java Web application.

S205: and generating and outputting a log according to the position parameter, the execution parameter and the time and content indicated by the notification.
For example, if the monitoring information represents a program that monitors a connection point in the Java program, that is, a program that monitors a position of the log output, the wrapper may acquire a notification corresponding to the connection point from the Spring frame, and acquire the time of the log output and the content of the log output from the notification.
Of course, the wrapper may also obtain the location parameter of the program of the connection point and the parameter related to execution (i.e., execution parameter) when the program of the connection point is executed.
Accordingly, the wrapper generates and outputs the log according to the acquired four-dimensional information (i.e., the position information about the position of the log output, the information about execution when the program of the log output is executed, the information about time of the log output, and the information about the content of the log output), so as to ensure the accuracy and reliability of the log output while automatically outputting the log.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a log output method of a Java Web application according to another embodiment of the present disclosure.
As shown in fig. 3, the method includes:
s301: and monitoring the running Java program to obtain monitoring information.
For example, the technical features of this embodiment that are the same as those of the above embodiment are not described in detail in this embodiment.
S302: and if the monitoring information represents the program monitoring the connection point in the Java program, acquiring a notification corresponding to the connection point from a Spring framework of the Java Web application.
The connection point is used for indicating the preset position of the log output of the Java program, and the time and the content for indicating the log output are notified, and the connection point and the notification are configured in the Spring framework of the Java Web application.
In some embodiments, the location of the Java program's log output may be achieved by:
the first step is as follows: and acquiring each section of code program of the Java program, and determining each section of code program of the Java program to determine the common code program of the Java program.
The second step is as follows: the location of the common code program is acquired, and the location of the common code program is determined as the log output location of the Java program.
The common code program is a code program having an association relationship with other code programs in each code program segment.
In some embodiments, the common code program includes: requesting one or more of a code program of a Java Web application, a code program calling an external application interface, and a code program executing a database.
By determining the public code program and determining the log output position of the Java program based on the public code program, the load of a developer can be greatly reduced, so that the developer developing the application logic is liberated from the attention on the operation and maintenance requirements, the labor cost and manual intervention are reduced, and the reliability and efficiency of log output are improved.
S303: an output level of the log output is determined according to the content of the log output indicated by the notification.
The output levels include, among other things, a compile (Debug) level (which may also be referred to as a Debug level), an alarm (Warn) level, and an Error (Error) level.
For example, the Spring frame includes a plurality of connection points, that is, there are positions in a Java program where a plurality of output logs are needed, a position of one output log corresponds to one connection point, and correspondingly, the Spring frame includes a plurality of notifications, one connection point corresponds to one notification, and the contents of log output indicated by the notifications corresponding to different connection points may be different, that is, output levels of log output applied by different connection points may be different.
For example, the output level of the log output of one connection point is a compile level, while the output level of the log output of another connection point is an alarm level.
S304: and determining the completeness of the output log according to the output level. Wherein the level is proportional to the degree of integrity, and the output levels of the compilation level, the alarm level, and the error level are sequentially increased.
Illustratively, the alarm level is higher than the compilation level, and accordingly, the integrity of the log corresponding to the alarm level is higher than the integrity of the log corresponding to the compilation level, i.e., the content of the log corresponding to the alarm level is relative to the content of the log corresponding to the compilation level.
Similarly, the error level is higher than the alarm level, and accordingly, the integrity of the log corresponding to the alarm level is higher than that of the log corresponding to the alarm level, that is, the content of the log corresponding to the alarm level is relative to that of the log corresponding to the alarm level.
S305: a log is generated and output based on the program of the connection point, the degree of completeness, and the time indicated by the notification.
In the embodiment, by determining the complete program and combining the complete degree to generate and output the log, the flexibility and diversity of log output can be realized, the requirements of different scenes are met, the application range of log output is widened, and the effectiveness and reliability of log output are improved.
In some embodiments, S305 may include two implementations as follows:
implementation mode 1: and if the time indicated by the notification is the time before the program of the connection point is executed, acquiring previous running information before the program of the connection point is executed, and generating and outputting a log according to the previous running information and the integrity. Wherein the pre-run information includes information about a program before the program of the connection point is executed.
Implementation mode 2: and if the time indicated by the notification is the time after the program of the connection point is executed, executing the program of the connection point, acquiring the post-operation information after the program of the connection point is executed, and generating and outputting a log according to the post-operation information and the integrity degree. Wherein the post-run information includes the pre-run information and related information when executing the program of the connection point.
For example, there may be two cases where the time indicated by the notification is the time before the program of the connection point is executed, that is, a log of the program before the program of the connection point needs to be generated; the other is that the time indicated by the notification is the time after the program of the connection point is executed, that is, a log after the program of the connection point needs to be generated for execution.
For example, the Java program includes n segments, the current program is the kth segment program, that is, the program of the connection point is the kth segment program, and if the time indicated by the notification is the time before the execution of the program of the connection point, it indicates that the log to be output may be the log generated by executing the first segment program to the kth-1 segment program, or may be the log generated by executing the kth-1 segment program; if the time indicated by the notification is the time after the execution of the program of the connection point, it is described that the log to be output may be the log generated by executing the first to k-th programs or the log generated by executing the k-th program.
Here, the notification indicating that the time is the time before the program of the connection point is executed may be referred to as a pre-notification. The notification indicating that the time is the time after the program of the connection point is executed may be referred to as a post notification.
That is, the notification may also be used to indicate a pre-notification, a post-notification (which may include post-return notifications and post-exception notifications), a post-end notification, and a surround notification.
Wherein pre-notification may be understood as outputting a log prior to execution of the program. Post notification may be understood as outputting a log after execution of a program. Post-return notification may be understood as outputting a log when the result of execution is obtained after execution of the program. Post exception notification may be understood as outputting a log if the executing program is abnormal (e.g., fails or fails to run, etc.). Surround notifications may be understood as a combination of front notifications and back notifications.
It should be noted that, in this embodiment, by generating and outputting the log at the time indicated by the notification, the log output can have strong pertinence in time, so that the output log has the technical effects of high reliability and traceability.
It should be understood that some technical features of the present embodiment may be combined with the foregoing embodiments to obtain a new embodiment, and similarly, some technical features of the foregoing embodiments may also be combined with the present embodiment to obtain a new embodiment, and the present embodiment is not limited to the combination manner.
According to another aspect of the embodiments of the present disclosure, a log output apparatus for a Java Web application is also provided.
