Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and system for generating business document numbers in a PaaS platform based on a lock mechanism. Background Art

[0002] In the implementation of a PaaS platform, the ability to configure numbering rules is provided for the number fields of business objects. The numbering rules may include a date (such as year, year and month, year, month, and day) + serial number, and it is possible to configure the reset of the serial number by year, year and month, or year, month, and day. When generating business documents based on business objects, the PaaS platform automatically generates the number attributes of these documents according to the numbering rules. Due to the existence of the serial number in the numbering rules, when multiple business documents are generated from one business object, there is a correlation between the documents, and the situation of duplicate serial numbers is likely to occur in a high-concurrency scenario of generating business documents. At the same time, due to the influence of the serial number reset factor, when the reset time node arrives, due to concurrency, the serial number is not reset. Both of the above situations will affect the accurate generation of document numbers in the PaaS platform. Therefore, a method for accurately and quickly generating automatic numbers in a certain high-concurrency scenario is needed. Summary of the Invention

[0020] Method Embodiment

[0021] According to an embodiment of the present invention, a method for generating a business document number of a PaaS platform based on a lock mechanism is provided. Figure 1 It is a flowchart of the method for generating a business document number of a PaaS platform based on a lock mechanism according to an embodiment of the present invention. As Figure 1 shown, the method for generating a business document number of a PaaS platform based on a lock mechanism according to an embodiment of the present invention specifically includes:

[0022] Step S101: Determine whether the serial number counter in the PaaS platform needs to be reset, and select to execute Step S102 or Step S103 according to the determination result, specifically including:

[0023] Compare the current time with the reset method and reset date in the numbering model to determine whether the serial number counter in the PaaS platform needs to be reset. If it needs to be reset, then select to execute Step S102;

[0024] If it does not need to be reset, then select to execute Step S103;

[0025] Step S102: Use the numbering model ID as the lock key and apply for a write lock based on the determination result, and select to execute Step S103 or re - execute Step S101 according to the write lock acquisition result, specifically including:

[0026] Use the numbering model ID as the lock key and apply for a write lock for the reset action. If the write lock is successfully acquired, then reset the serial number counter according to the start number attribute value of the numbering model, update the reset date of the numbering model to the current date, release the write lock, and execute Step S103;

[0027] If the write lock acquisition fails, then re - execute Step S101;

[0028] Among them, when applying for a write lock, it will wait for the release of all read locks on the current lock key;

[0029] Step S103: Use the numbering model ID as the lock key and apply for a read lock based on the judgment result. Generate a PaaS platform business document number according to the read lock acquisition result, or re-execute step S101, which specifically includes:

[0030] Use the numbering model ID as the lock key and apply for a read lock for the action of obtaining the serial number. If the read lock acquisition is successful, obtain the current value from the serial number counter and release the read lock, and generate a PaaS platform business document number according to the obtained serial number value and the numbering format in the numbering model;

[0031] If the read lock acquisition fails, re-execute step S101;

[0032] Among them, when applying for a read lock, if there is a write lock on the current lock key, the read lock application will wait for the write lock to be released.

[0033] The following combines the specific situation of the PaaS platform business document number generation method based on the lock mechanism in the embodiments of the present invention, as Figure 2 shown, to elaborate on the above technical solutions of the embodiments of the present invention in detail.

[0034] 1. Numbering model definition

[0035] After the numbering rule is configured, establish numbering model data according to the configuration parameters. The main attributes are as follows:

[0036] Numbering model ID: Uniquely identifies the numbering model data.

[0037] Numbering format: The numbering format defines the overall format of the automatic numbering rule.

[0038] For example: {YYYY}{MM}{dd}-{0000}, where {YYYY} represents the year, {MM} represents the month, {dd} represents the date, and {0000} represents a 4-digit serial number.

[0039] Starting number: Records from which specific number the serial number starts.

[0040] Reset method: Records the method by which the serial number is reset, for example: reset by year, reset by month, reset by day, not reset.

[0041] Reset date: Records the date when the numbering is reset.

[0042] 2. Serial number counter

[0043] Define a counter for the serial number of a numbering rule, and the initial value of the counter is the value of the starting number attribute of the numbering model. There are mainly two scenarios for operating the counter:

[0044] ①Scenario of generating serial numbers: When generating business documents, obtain the current value from the counter, increment the counter by 1 automatically, and save the current value of the counter. During the current processing, it is necessary to prevent the counter from being reset.

[0045] ②Scenario of resetting serial numbers: When the reset condition is met, assign a value to the counter according to the start number attribute value of the numbering model. During the current processing, it is necessary to prevent the counter from being used for generating serial numbers.

[0046] When analyzing the above two operation scenarios with the serial number counter as the core, the scenario of generating serial numbers can be defined as the read scenario of the counter. When multiple business documents are generated simultaneously, the essence of each document is to read the latest value of the counter, and the counter itself controls the increment of the value during reading, and the processing of the whole process is not intervened by the outside. The scenario of resetting serial numbers is defined as the write scenario of the counter. When the counter needs to be reset, in fact, the outside writes the value of the counter.

[0047] At the same time, since the usage frequency of the scenario of generating serial numbers is much higher than that of the scenario of resetting serial numbers, the embodiments of the present invention adopt the read-write lock method to protect the use of the serial number counter and ensure that the counter can accurately generate serial numbers when used in high concurrency.

[0048] 3. Process of number generation

[0049] When a business document number needs to be generated, the general generation process is as follows:

[0050] Step 1: Compare the current time with the reset method and reset date in the numbering model to determine whether the serial number counter needs to be reset. When the result of the judgment is that the serial number counter needs to be reset, perform the operation in Step 2; when the serial number counter does not need to be reset, perform Step 3.

[0051] Step 2: Use the numbering model ID as the lock key to apply for a write lock for the upcoming reset action. When applying for the write lock, it will wait for the release of all read locks on the current lock key. There are mainly two results of locking the write lock:

[0052] ①When the write lock is successfully locked, reset the serial number counter according to the start number of the numbering model, update the reset date of the numbering model to the current date, and then release the write lock and perform the operation in Step 3.

[0053] ②When the write lock fails to be locked, for example: the lock timeout or other exceptions occur, go back to Step 1 and execute again.

[0054] Step 3: Use the numbered model ID as the lock key to apply for a read lock for the action of about to obtain the serial number. If there is a write lock on the current lock key, the read lock application will wait for the write lock to be released. There are mainly two results for adding the read lock:

[0055] ① When the read lock is successfully added, obtain the current value from the counter, then release the read lock, and generate the business document number according to the obtained serial number value and the number format in the numbered model.

[0056] ② When the read lock addition fails, for example: the lock addition times out or other exceptions occur, go back to Step 1 and execute again.

[0057] In addition, in a distributed environment, there are multiple ways to implement the increment of the counter value. The specific method to be adopted is not limited in the embodiments of the present invention.

[0058] And in a distributed environment, there are also multiple ways to implement the read-write lock. The specific method to be adopted is not limited in the embodiments of the present invention.

[0066] If the write lock acquisition fails, the judgment module is executed again;

[0067] Among them, when applying for a write lock, it will wait for the release of all read locks on the current lock key;

[0069] Apply for a read lock with the numbered model ID as the lock key for the action of obtaining the serial number.
