Description

TECHNICAL FIELD

[0001] The present application relates to the computer technical field, and particularly relates to a PaaS platform business document number generation method and system based on a lock mechanism. BACKGROUND

[0002] In the PaaS platform implementation, a configuration number rule ability is provided for the number field of a business object, and the number rule includes a date (such as year, year-month, year-month-day) + serial number mode, and the serial number can be configured to be reset according to year, year-month, year-month-day. When a business document is generated according to a business object, the PaaS platform automatically generates the number attribute of the document according to the number rule. Due to the existence of the serial number in the number rule, when a plurality of business documents are generated by a business object, the documents have relevance, and in a high-concurrency business document generation scenario, the serial number is likely to be repeated. Meanwhile, due to the influence of the serial number reset factor, when the time node of the reset arrives, due to concurrency, the serial number is not reset. The above two cases will affect the accurate generation of the document number by the PaaS platform, and therefore a method for accurately and quickly generating an automatic number in a certain high-concurrency scenario is required.

[0020] Method Example

[0021] According to an embodiment of the present invention, a method for generating a business document number on a PaaS platform based on a lock mechanism is provided. Figure 1 This is a flow chart of a method for generating a business document number on a PaaS platform based on a lock mechanism according to an embodiment of the present invention. Figure 1 As shown, the method for generating a PaaS platform business document number 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 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 reset is required, select step S102;

[0024] If no reset is required, step S103 is selected;

[0025] Step S102: Using the model ID as the lock key and applying for a write lock based on the judgment result, and then selecting to execute step S103 or re-execute step S101 based on the write lock result, specifically including:

[0026] The numbering model ID is used as the lock key and a write lock is applied for the reset action. If the write lock is successfully locked, the serial number counter is reset according to the starting number attribute value of the numbering model, the reset date of the numbering model is updated to the current date, the write lock is released, and step S103 is executed;

[0027] If the write lock fails, step S101 is executed again;

[0028] When applying for a write lock, it will wait for all read locks on the current lock key to be released;

[0029] Step S103: Using the numbering model ID as the lock key and applying for a read lock based on the judgment result, generating a PaaS platform business document number based on the read lock result, or re-execute step S101, specifically including:

[0030] Use the numbering model ID as the lock key and apply for a read lock to obtain the serial number. If the read lock is successfully acquired, obtain the current value from the serial number counter and release the read lock. Generate a PaaS platform business document number based on the obtained serial number value and the numbering format in the numbering model.

[0031] If the read lock fails, step S101 is executed again;

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

[0033] The following is a specific example of a method for generating a business document number on a PaaS platform based on a lock mechanism according to an embodiment of the present invention. Figure 2 As shown, the above technical solution of the embodiment of the present invention is described in detail.

[0034] 1. Numbering model definition

[0035] After the numbering rule is configured, the numbering model data is created based on the configuration parameters. The main attributes are as follows:

[0036] Model ID: uniquely identifies the model data.

[0037] Numbering format: The numbering format defines the overall format of the auto-numbering sequence.

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

[0039] Start number: record the specific number from which the serial number starts.

[0040] Reset method: record the method by which the serial number is reset, for example: reset by year, reset by month, reset by day, no reset.

[0041] Reset Date: The date on which the record number is reset.

[0042] 2. Serial number counter

[0043] Define a counter for the serial number of a numbering rule. The initial value of the counter is the value of the start number attribute of the numbering model. There are two main scenarios for operating the counter:

[0044] ① Generate serial number scenario: When generating a business document, obtain the current value from the counter, automatically increment the counter by 1, and save the current value. During the current processing, it is necessary to prevent the counter from being reset.

[0045] ② Reset serial number scenario: When the reset condition is met, the counter is assigned a value based on the start number attribute value of the numbering model. During the current processing, it is necessary to prevent the counter from being used to generate serial numbers.

[0046] When analyzing the two operational scenarios above, focusing on the serial number counter, we can define the scenario of generating serial numbers as a counter read scenario. When multiple business documents are generated simultaneously, each document essentially reads the latest value of the counter. The counter itself controls the increment of the value during reading, and the entire process is not subject to external interference. The scenario of resetting serial numbers is defined as a counter write scenario. When resetting the counter, the counter value is actually written externally.

[0047] At the same time, since the frequency of use of the serial number generation scenario is much higher than the frequency of use of the serial number reset scenario, the embodiment of the present invention adopts a read-write lock method to protect the use of the serial number counter, ensuring that the counter can accurately generate serial numbers when used with high concurrency.

[0048] 3. Number generation process

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

[0050] Step 1: Determine whether the serial number counter needs to be reset based on the current time, the reset method, and the reset date in the numbering model. If the result of the determination is that the serial number counter needs to be reset, proceed to step 2; if the serial number counter does not need to be reset, proceed to step 3.

[0051] Step 2: Use the model ID as the lock key to apply for a write lock for the upcoming reset. Applying a write lock will wait for all read locks on the current lock key to be released. There are two main results of applying a write lock:

[0052] ① When the write lock is successfully locked, the serial number counter is reset according to the starting number of the numbering model, and the reset date of the numbering model is updated to the current date. Then the write lock is released and step 3 is executed.

[0053] ② When the write lock fails, for example, the lock times out or other exceptions occur, return to step 1 and execute again.

[0054] Step 3: Use the model ID as the lock key to apply for a read lock for the action of obtaining the serial number. If a write lock exists on the current lock key, the read lock application will wait for the write lock to be released. There are two main results of the read lock application:

[0055] ① When the read lock is successfully locked, the current value is obtained from the counter, and then the read lock is released. The business document number is generated based on the obtained serial number value and the numbering format in the numbering model.

[0056] ②When the read lock fails, for example, the lock times out or other exceptions occur, return to step 1 and execute again.

[0057] In addition, in a distributed environment, there are multiple ways to implement the self-increment of the counter value, and the embodiment of the present invention does not limit which specific method is adopted.

[0058] Furthermore, in a distributed environment, there are multiple ways to implement a read-write lock, and the embodiment of the present invention does not limit which specific way is adopted.

[0064] The write lock module 32 is used to apply for a write lock using the model ID as the lock key and based on the judgment result, and to select to execute the read lock module or re-execute the judgment module according to the write lock result, specifically for:

[0065] 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 locked, reset the serial number counter according to the starting 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 the read lock module;

[0066] If the write lock fails, the judgment module is re-executed;

[0067] When applying for a write lock, it will wait for all read locks on the current lock key to be released;

[0068] The read lock module 34 is used to apply for a read lock based on the judgment result using the number model ID as the lock key, and to generate a PaaS platform business document number based on the read lock result, or to re-execute the judgment module, specifically for:

[0069] Use the numbering model ID as the lock key and apply for a read lock to obtain the serial number. If the read lock is successfully acquired, obtain the current value from the serial number counter and release the read lock. Generate a PaaS platform business document number based on the obtained serial number value and the numbering format in the numbering model.

[0070] If the read lock fails, the judgment module is re-executed;

[0071] Among them, if there is a write lock on the current lock key when applying for a read lock, the read lock application will wait for the write lock to be released.
