It should be noted that FIG. 1 is only one example of a particular specific example and is intended to illustrate the types of components that may be present in the computing devices described above.

Under the above operating environment, according to a first aspect of the present embodiment, there is provided an expression-based execution method implemented by the computing apparatus shown in fig. 1. Fig. 2 shows a flow diagram of the method, which, with reference to fig. 2, comprises:

s202: pre-configuring a first expression corresponding to a plurality of services, and pre-compiling the first expression to generate a corresponding first data sequence;

s204: determining a second data sequence corresponding to the target service from the first data sequence; and

s206: and obtaining an execution result according to the second data sequence.

Specifically, the background configuration system is preset with a plurality of tags for configuring the expression, and the computing device drags the tags to combine the tags into the expression (i.e., the first expression). The first expression is used for generating business logic, and the number of the first expression is multiple. Therefore, the computing equipment configures the first expressions corresponding to all the services in advance through the background configuration system. The first expression is then precompiled to generate a corresponding data sequence (i.e., a first data sequence), which may be, for example, an MD5 value.

Further, to implement the target service, the computing device determines an expression (i.e., a second expression) corresponding to the target service according to the service ID of the target service, and obtains a data sequence (i.e., a second data sequence) corresponding to the expression (i.e., the second expression) from all the first expressions.

Further, the computing device executes the data sequence corresponding to the target service to obtain a corresponding execution result, thereby completing development of the target service.

As described in the background, many demands today have some functional or logical adjustments due to business changes and developments, and if hard coded, each adjustment requires development of code and release of services. In order to solve the above problems, there are two main methods in the prior art: the first method is mainly a method of configuring some core variable parameters through database fields or through json format, which can be precise to specific index configuration, is friendly to service, but does not support common logic control, and the service logic must be hard-coded in codes, thereby resulting in reduced efficiency. The second one is mainly to realize configurability through various expressions and can realize more complicated logic control, but because of the coding knowledge, the method is not very friendly to common business personnel and is not very convenient to debug.

For the above technical problem, according to the technical solution of the embodiment of the present application, the computing device performs pre-compilation on all expressions, and stores the generated first data sequence. Therefore, when the expression is needed to realize service or carry out logic adjustment, the expression does not need to be precompiled in real time. And the service function is realized in an expression mode, so that the service function can be quickly realized without coding, and the development efficiency is improved. In addition, the technical scheme configures the expression by dragging the parameter tag, the logic judgment is displayed more intuitively, common service personnel can configure the expression, code debugging is not needed, and the applicability of the expression is ensured. And the technical problems of low efficiency and difficult debugging caused by frequent change of business logic in the prior art are solved.

Optionally, the operation of determining a second data sequence corresponding to the target service from the first data sequence includes: determining a corresponding second expression according to the target service; generating a corresponding hash value according to the second expression; and determining a second data sequence from the first data sequence according to the hash value.

Specifically, referring to fig. 3, the computing device determines an expression (i.e., a second expression) corresponding to the business target according to the ID of the business target. And then the computing equipment generates a hash value of the expression according to the expression, and matches the hash value with all the key values of the first data sequence according to the hash value, so as to inquire the data sequence (namely, the second data sequence) corresponding to the hash value. Wherein each first data sequence has a unique corresponding key value, and wherein the key value is a hash value.

In addition, under the condition that the computing device does not inquire the data sequence corresponding to the hash value, the computing device can directly generate a corresponding data sequence according to the second expression corresponding to the target service and store the data sequence.

Therefore, the technical scheme queries the pre-stored data sequence through the hash value, thereby improving the query efficiency and speed.

Optionally, the method further comprises: the first data sequence is stored to a database and/or a cache.

Specifically, after generating the first data sequence, the computing device stores the first data sequence in a database and/or a cache, generates a key value uniquely corresponding to the first data sequence, and stores the key value together. The computing device may then retrieve the data sequence corresponding to the target service from a database or cache. Therefore, the technical scheme stores the data sequence, so that the safety of the data sequence is improved.

Optionally, the method further comprises: and under the condition that a first expression corresponding to a plurality of services is configured in advance, checking the first expression.

Specifically, after configuring a first expression corresponding to a plurality of services, the computing device checks the syntax and logic of the first expression, thereby performing correctness check on the first expression. After the computing device verifies the first expression, if the first expression is judged to have grammatical or logical errors, corresponding error positions and reasons can be returned, and therefore the first expression can be corrected.

Therefore, on the premise of confirming the correctness of grammar and logic, the technical scheme can update the cache in real time according to the service function, and immediately take effect, thereby achieving the capability of hot deployment.

In addition, the scheme provides simple logic control based on MVEL expression to achieve a certain light code function, and the method comprises the following steps:

1. the background configuration system configures the expression of the corresponding service according to the service rule and stores the expression into the database and the cache

2. Firstly, an expression corresponding to the current service is inquired from a database or a cache.

3. And inquiring whether a precompiled expression exists locally or not according to the corresponding expression. If the expression exists, the expression is directly taken out to be executed, if the expression does not exist, the expression is precompiled, and the precompiled expression is stored in a cache.

4. And executing the precompiled expression by the combined input parameter input expression and obtaining a result.

5. And triggering the corresponding business logic according to the expression result.

And aiming at the configuration expression in the first step, configuring input parameters, pre-compiling in advance, checking grammar and hot updating the pre-compiled codes to a corresponding server aiming at each service.

The query and precompiled code for the Mvel expression is as follows:

the key value used by the local cache is the md5 value of the native expression, so that the uniqueness of the corresponding cache can be ensured once the native expression is modified.

Further, referring to fig. 1, according to a second aspect of the present embodiment, there is provided a storage medium. The storage medium comprises a stored program, wherein the method of any of the above is performed by a processor when the program is run.

Thus, according to the present embodiment, the computing device precompiles all of the expressions and stores the generated first data sequence. Therefore, when the expression is needed to realize the service or carry out logical adjustment, the expression does not need to be precompiled in real time. And the service function is realized in an expression mode, so that the service function can be quickly realized without coding, and the development efficiency is improved. In addition, the technical scheme configures the expression by dragging the parameter tag, so that the logic judgment is displayed more intuitively, common service personnel can configure the expression, code debugging is not needed, and the applicability of the expression is ensured. And the technical problems of low efficiency and difficult debugging caused by frequent change of business logic in the prior art are solved.
