The best implementation of this application

1, an embodiment of the present application provides a method for configuring attributes of the log4j log framework, including the following steps:

S1. Receive an attribute configuration instruction to the log4j log framework, where the attribute configuration instruction carries a specified attribute value;

S2. According to the attribute configuration instruction, retrieve a preset configuration file, wherein a designated system variable placeholder is set in the position of the designated attribute in the configuration file, and the designated system variable placeholder refers to a designated system Special symbols for variables;

S3. Obtain the designated system variable by using the designated system variable placeholder, and determine whether the designated system variable is the same as the designated attribute value;

S4. If the designated system variable is not the same as the designated attribute value, call a preset system variable editing method to edit the designated system variable to the designated attribute value;

S5. Invoke a preset configuration file loading method, so that the log4j log framework updates the current attribute value to the specified attribute value according to the configuration file, thereby completing the attribute configuration of the log4j log framework.

This application uses designated system variable placeholders, and when the attributes need to be modified, only the designated system variables can be edited accordingly, thereby overcoming the shortcomings of time-consuming and inability to quickly take effect caused by restarting the server.

As described in step S1 above, an attribute configuration instruction to the log4j log framework is received, and the attribute configuration instruction carries a specified attribute value. The attribute configuration instruction is used to instruct to configure the attributes of the log4j log framework, for example, to configure attributes such as log level and log file storage path, with the purpose of configuring the specified attribute to be the specified attribute value carried by the attribute configuration instruction.

As described in step S2 above, according to the attribute configuration instruction, a preset configuration file is called, wherein a designated system variable placeholder is set in the position of the designated attribute in the configuration file, and the designated system variable placeholder Symbols refer to special symbols that represent specified system variables. For the log4j logging framework, the configuration of properties requires the use of preset configuration files to obtain the property values to be configured. In this application, a designated system variable placeholder is set at the position of the designated attribute in the configuration file, so that when the attribute needs to be modified, only the designated system variable can be edited accordingly, and the configuration file does not need to be modified. Among them, placeholders are symbols that occupy a fixed position and wait for you to add content to them; and system variable placeholders are special symbols that represent system variables; system variables refer to the data storage location defined by the system. Recorded data. Moreover, the system variable placeholders are not ordinary placeholders, because the system variable placeholders represent system variables, and the system variables can be edited without opening the configuration file, so that the configuration file is not modified. The modification of attributes therefore avoids the disadvantages of time-consuming and unable to take effect quickly due to the need to restart the server during attribute configuration (modification) in the traditional method. Wherein, the state of the system variable placeholder in the configuration file is, for example: all attribute positions in the configuration file are occupied by system variable placeholders; or, there is only designated The attribute position is occupied by a system variable placeholder; or, other attribute positions in the configuration file except the specified attribute position record the attribute value or are occupied by the system variable placeholder.

As described in step S3 above, the designated system variable is obtained by using the designated system variable placeholder, and it is determined whether the designated system variable is the same as the designated attribute value. From the foregoing, the system variable placeholder is a special symbol representing the system variable. Therefore, the designated system variable can be obtained by querying the designated system variable placeholder. Then judge whether the specified system variable is the same as the specified attribute value; if the specified system variable is the same as the specified attribute value, that is, the current attribute value is the same as the specified attribute value, so no attribute update is required; If the system variable is different from the specified attribute value, an attribute update operation is required.

As described in step S4 above, if the designated system variable is different from the designated attribute value, a preset system variable editing method is called to edit the designated system variable to the designated attribute value. If the specified system variable is different from the specified attribute value, an attribute update operation is required. A method is also called a function, which is a collection of statements that perform a function together. The system variable editing method is used to edit the system variable. Since the system variable editing method is preset, the system variable editing can be realized by directly calling this method. The method for editing the system variable is, for example, obtaining the position of the system variable; deleting the system variable data; recording the pre-prepared variable data into the system variable position, so as to realize the editing of the system variable.

As described in step S5 above, call the preset configuration file loading method, so that the log4j log framework updates the current attribute value to the specified attribute value according to the configuration file, thereby completing the attribute configuration of the log4j log framework . The configuration file loading method is used to load a configuration file to update all or part of the attributes. Therefore, by calling the preset configuration file loading method, the attribute update operation can be performed, so that the log4j log framework updates the current attribute value to the specified attribute value according to the configuration file, thereby completing the attributes of the log4j log framework Configuration.

In one embodiment, the preset configuration file is called according to the attribute configuration instruction, wherein a designated system variable placeholder is set in the position of the designated attribute in the configuration file, and the designated system variable occupies Place symbol refers to the special symbol representing the designated system variable before step S2, including:

S11. Count information about the number of times that the attributes of the log4j log frame have been modified within a predetermined time, and record the attributes whose number of times have been modified over a preset number threshold as attributes to be modified;

S12. Set a system variable placeholder in the position of the attribute to be modified in the configuration file.

As described above, it is achieved that the position of the tag attribute in the configuration file is set as a system variable placeholder. If some attributes of the log4j log framework are not frequently modified, then these attributes can be directly recorded in the configuration file with specific attribute values, and there is no need to use system variable placeholders. However, for attributes that have been modified more than the preset number threshold within a predetermined time, because they are often modified, system variable placeholders need to be used. Thus, the attributes in the configuration file are divided into specific attribute values or system variable placeholders according to the number of times they have been modified, thereby reducing the increase in system burden caused by all use of system variable placeholders in the configuration file ( System variable placeholders take up more space) defects.

In one embodiment, the step S3 of obtaining the designated system variable by using the designated system variable placeholder, and determining whether the designated system variable is the same as the designated attribute value, includes:

S301: Acquire the designated system variable by using the designated system variable placeholder according to the preset correspondence between the system variable placeholder and the system variable;

S302: Calculate the similarity value between the designated system variable and the designated attribute value by using a preset similarity algorithm;

S303: If the similarity degree value is less than a preset similarity degree threshold, determine that the designated system variable is different from the designated attribute value.

As described above, it is achieved that the designated system variable is obtained by using the designated system variable placeholder, and it is determined whether the designated system variable is the same as the designated attribute value. Among them, the preset similarity algorithm is, for example, the WMD algorithm (word move's distance), the simhash algorithm, and the algorithm based on cosine similarity and word frequency vector similarity. The foregoing algorithms are all mature algorithms and will not be repeated here. If the similarity value is less than the preset similarity threshold, it is determined that the specified system variable is not the same as the specified attribute value; if the similarity value is not less than the preset similarity threshold, it is determined that the specified The system variable is the same as the specified attribute value. The purpose of this embodiment is to be compatible with the miswriting of the specified attribute value carried by the attribute configuration instruction. For example, if DEBUG is mistakenly written as DEBAG, the similarity algorithm according to this embodiment will determine that the two are the same, so there is no need to update the attribute. This avoids the use of ordinary text comparison methods (comparing characters one by one, if there is a difference, the judgment is not the same) to judge the two as different, which will lead to the subsequent incorrect unrecognizable DEBAG (DEBUG is the log level, and DEBAG is not) Set to the attribute value of the log4j log frame, causing serious errors.

In one embodiment, the step S302 of calculating the similarity value between the designated system variable and the designated attribute value by using a preset similarity algorithm includes:

S3021, adopt the formula:

Calculate the similarity value between the designated system variable and the designated attribute value; where similarity is the similarity value, A is the character frequency vector of the designated system variable, B is the character frequency vector of the designated attribute value, Ai Is the number of occurrences of the i-th character of the designated system variable, and Bi is the number of occurrences of the i-th character of the designated attribute value.

As described above, it is realized that the preset similarity algorithm is used to calculate the similarity value between the designated system variable and the designated attribute value. The character frequency vector is a multidimensional vector formed by taking the number of times (frequency) of each character of the designated system variable or the designated attribute value as the dimensional value of the vector. That is, A=(A1,A2,...,An), where An is the number of times the last character (a total of n characters) appears. The similarity algorithm is calculated according to the cosine similarity between the designated system variable and the designated attribute value, so as to reflect the degree of similarity between the designated system variable and the designated attribute value. When the value of similarity is closer to 1, the more similar is; the closer to 0, the less similar.

In one embodiment, if the designated system variable is not the same as the designated attribute value, the step S4 of calling a preset system variable editing method to edit the designated system variable to the designated attribute value includes :

S401: If the specified system variable is not the same as the specified attribute value, determine whether the user account sending the attribute configuration instruction is in a preset list of authorized users;

S402: If the user account sending the attribute configuration instruction is in the preset list of authorized users, determine whether the specified attribute value exceeds the preset parameter range of the specified system variable;

S403: If the specified attribute value does not exceed the preset parameter range of the specified system variable, call a preset system variable editing method to edit the specified system variable to the specified attribute value.

As described above, before calling the preset system variable editing method to edit the designated system variable to the designated attribute value, authorization verification and parameter verification are implemented. Among them, the user accounts in the preset list of authorized users have the authority to edit system variables, so as to reduce the possibility of system variables being tampered with. The preset parameter range limits the parameter content that the specified system variable can be set. For example, the log level can be set to five levels: DEBUG, INFO, WARN, ERROR and FATAL, that is, the preset parameter range is DEBUG, INFO, WARN , ERROR and FATAL. Therefore, authorization verification and parameter verification are performed first to reduce the possibility of attribute configuration errors.

In one embodiment, if the user account that sends the attribute configuration instruction is in the preset list of authorized users, after the step S402 of determining whether the specified attribute value exceeds the preset parameter range of the specified system variable ,include:

S4021. If the specified attribute value exceeds the preset parameter range of the specified system variable, generate a parameter error warning message;

S4022. Return the warning message of the parameter error to the terminal that sent the attribute configuration instruction of the log4j log frame.

As described above, it is realized that the reminder information of the parameter error is returned to the terminal that sends the attribute configuration instruction of the log4j log framework. If the specified attribute value exceeds the preset parameter range of the specified system variable, the specified attribute value cannot be configured, otherwise it will cause an error in the log4j log framework. For example, the preset parameter range of the log level is DEBUG, INFO, WARN , ERROR and FATAL, and the specified attribute value is right, which exceeds the preset parameter range of the specified system variable, a warning message of parameter error should be generated, and the warning message of the parameter error should be returned to the sender of the log4j log frame The terminal of the attribute configuration command.

In one embodiment, the attributes other than the specified attributes in the configuration file record preset attribute values, and the preset configuration file loading method is invoked, so that the log4j log framework is based on the configuration file Updating the current attribute value to the designated attribute value to complete the step S5 of the attribute configuration of the log4j log framework includes:

S501. Invoke a preset configuration file loading method, and update the specified attribute of the log4j log frame to the specified attribute value according to the configuration file;

S502. Keep the values of the attributes other than the specified attributes, so as to complete the attribute configuration of the log4j log framework.

As mentioned above, the property configuration of the log4j log framework is completed. In this embodiment, other attributes in the configuration file other than the specified attribute record the preset attribute value, so there is no need to update the other attributes when performing attribute configuration (attribute update) (so the configuration file is not modified, so It is impossible to change other attributes), which reduces the amount of calculation and improves the speed of attribute configuration. Accordingly, only the designated attribute of the log4j log framework is updated to the designated attribute value, and the values of the other attributes except the designated attribute are retained, thereby completing the attribute configuration of the log4j log framework.

As described in the aforementioned unit 40, if the designated system variable is different from the designated attribute value, a preset system variable editing method is called to edit the designated system variable to the designated attribute value. If the specified system variable is different from the specified attribute value, an attribute update operation is required.
