4. The method of claim 3, wherein before generating at least one processing code based on the pre-edited processing code template and the respective first entity class names if the processing code further comprises a business layer code, the method further comprises:

determining a class name for each data access layer code based on the at least one data access layer code;

wherein the generating at least one processing code based on the pre-edited processing code template and the respective first entity class names further comprises:

determining replaceable codes in a service layer code template edited in advance;

and replacing the replaceable codes in the service layer code template by using the first entity class names and the class names of the data access layer codes to obtain at least one service layer code.

5. The method of claim 4, wherein if the process code further comprises controller-level code, before generating at least one process code based on the pre-edited process code template and the respective first entity class names, the method further comprises:

determining second entity type codes corresponding to the database tables respectively based on a second entity type code template edited in advance and the at least one database table, wherein the attribute names of the second entity type codes are different from the attribute names of the first entity type codes;

determining each second entity class name based on the second entity class codes respectively corresponding to each database table;

determining a class name of each service layer code based on the at least one service layer code;

determining replaceable codes in a pre-edited controller layer code template;

and replacing the replaceable codes in the controller layer code template by using the first entity class names, the second entity class names and the class names of the service layer codes to obtain at least one controller layer code.

6. The method of claim 5, wherein before generating at least one processing code based on the pre-edited processing code template and the respective first entity class names if the processing code further comprises microservice layer code, the method further comprises:

determining a third entity class code corresponding to each database table respectively based on a pre-edited third entity class code template and the at least one database table, wherein the attribute name of the third entity class code is different from the attribute name of the first entity class code, and the attribute name of the third entity class code is different from the attribute name of the second entity class code;

determining each third entity class name based on the third entity class codes respectively corresponding to each database table;

determining replaceable codes in a micro service layer code template edited in advance;

and replacing the replaceable codes in the micro service layer code template by using the first entity class names, the third entity class names and the class names of the service layer codes to obtain at least one micro service layer code.

7. The method of claim 6, wherein after obtaining at least one microservice layer code, further comprising:

determining a class name of each micro service layer code based on the at least one micro service layer code;

and replacing the replaceable codes in the controller layer code template by using the class names of the micro service layer codes, the second entity class names and the third entity class names to obtain at least one controller layer code.

8. A code generation apparatus, comprising:

a second determining module, configured to determine each first entity class name based on the first entity class code corresponding to each database table;

9. An electronic device, comprising:

one or more processors;

a memory;

one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the one or more processors, the one or more programs configured to: executing the code generation method according to any of claims 1 to 7.

10. A computer-readable storage medium on which a computer program is stored, the program, when executed by a processor, implementing the code generation method of any one of claims 1 to 7.
