Background

With the development of science and technology and the increasing pace of social life, the requirements of users on the use of software also become higher. Although the standardization degree of enterprise software is increasing, the use of software development auxiliary tools in the development process is also increasingly popular. However, most domestic software enterprises still have the problem that the self-building of development frames and development tools are not uniform, so that the enterprises are required to be equipped with comprehensive frame engineers and technicians and the self-improvement and self-growth of domestic software consultation technical enterprises. The comprehensive requirements for managers and developers are correspondingly improved, and the comprehensive capability of domestic developers is relatively low along with the influence of social environment and other reasons, so that the labor cost of software enterprise development is increased, and the enterprise burden is increased, and the profit is low.

The rapid development platforms proposed in the market aiming at the current situation are relatively few, the technology is not mature, the functions are simple, the flexibility is not enough, and the service requirements of various environments and different platforms cannot be met. The prior art has the following defects:

(1) secondary development is not supported. Most of the existing service logic software in the current market does not support the secondary development of corresponding service logic, the same service logic is required to be used as a function support, and if the service logic is changed or changed into a more complex processing mode, the existing software cannot perform corresponding secondary development processing and API interface development integration.

(2) The code coupling degree is high, and the flexibility is poor. Most of software in the current market is visual operation, different business logics and complex business logics with high difficulty cannot be competent, part of business logic codes cannot be reused for developers, and program import and function deployment cannot be carried out aiming at different development environments and IDE.

In summary, the prior art still lacks an effective technical solution for the above problems.

From the above description, it can be seen that the automatic generation method of the second code according to the embodiment of the present invention achieves the following technical effects:

1. modeling and rapid development

In the actual development process of the project, the model development shortens the development period of the project, and saves manpower, material resources and learning cost; the code efficiency of developers can be improved by more than 70%; the module development can carry out longitudinal time development on the front end and the background through a reasonable layering mechanism.

3. Low coupling, high cohesion

More than 95% of the model is realized based on interface development, low coupling degree between codes is formed, and each component and module can be called by the model, so that high cohesion of the system is enhanced.

Such as: the model has more interfaces and less inheritance, and the inheritance is a coupling through the analysis of the coupling. If the child class A inherits the parent class B, either directly or indirectly, the child class A must rely on the parent class B. Subclass a must be used in an environment where parent B exists, and parent B cannot be used without subclass a, which affects the portability of subclass a. Once any change occurs to parent class B, changing or removing a function name, or changing a function parameter, subclass a will have to be changed or even overwritten. Such a change is catastrophic given that the subclasses of parent class B are tens to hundreds, even across the various modules of the project. The model strictly realizes the software design quality standard of low coupling and high cohesion according to the development requirements of java codes.
