s101: and receiving service configuration information submitted by a client on the service platform when the service platform runs.
The service platform is an application program which is used for providing user service and runs on cloud computing infrastructure. In the embodiment of the present application, the Service platforms include a SaaS (Software-as-a-Service, SaaS for short) Platform and a PaaS (Platform-as-a-Service, PaaS for short) Platform. The services provided by the SaaS platform to the user are application programs running on the cloud computing infrastructure, the user can access the application programs through a client interface on various devices, such as a browser, and the user does not need to manage or control any cloud computing infrastructure, including a network, a server, an operating system, storage and the like. The PaaS platform provides services for users by deploying applications developed or purchased by the users using provided development languages and tools (e.g., Java, python,. Net, etc.) to the cloud computing infrastructure of the provider, and the users do not need to manage or control the underlying cloud infrastructure, including networks, servers, operating systems, storage, etc., but the users can control the deployed applications and possibly the configuration of the hosting environment running the applications.
The service platform is provided with a first access page for the user to use the service at the client side, and is also provided with a second access page for the user to create or modify the service, and the user can submit service configuration information on the second access page. The service configuration information is used for creating or modifying the service of the service platform; the service configuration information comprises information for changing a data table structure of a database in the service platform, information for generating a service matched with the changed data table structure of the database, service operation interface information and the like. The data table structure is used for determining a file name of a data table, fields contained in the data table, field names of the fields, field types and field lengths, and the information of the data table structure of the change database comprises a change data table name, fields contained in the change data table, field names of the fields, field types of the fields, field lengths of the fields and the like, wherein the change comprises new addition, modification or deletion. In the embodiment of the application, the data table of the database of the service platform is changed into the data table corresponding to the service in the service configuration information, where the service may be an existing service of the service platform or a service to be created according to the service configuration information. The service generation request can be a code written by a user, or a code automatically generated by the service platform through operations such as graphical dragging on a service platform interface by the user. The information for generating the service matched with the data table structure of the changed database is specifically information for performing services such as query, addition, modification and deletion on the data table structure of the changed database. The service operation interface information is interface information displayed to the user in the service generated on the client according to the service configuration information and an operation component for providing interaction between the user and the service platform, for example, a service page is provided on the client, and an operation button, a search box and the like are provided on the service page, so that the user can inquire, add, modify and delete data of a data table of a database corresponding to the service.

When the data stored in the data table of the changed database is inquired, added, modified and deleted, the database statement is generated through the framework according to the parameters input by the user.
The dynamic proxy technology is a proxy class created during program operation, wherein the proxy class is mainly responsible for preprocessing messages for the delegation class, filtering messages, forwarding messages to the delegation class, processing messages after events, and the like. There is usually an association relationship between the proxy class and the proxy class, and an object of a proxy class is associated with an object of a proxy class, and the object of the proxy class does not actually implement a service, but provides a specific service by calling a related method of the object of the proxy class. The service platform of the exemplary embodiment of the present application is developed based on JAVA language technology, and the bytecode is code that can be recognized and executed by a virtual machine in JAVA.
S105: and loading and running the bytecode generation service, and controlling a service platform of the client to display the service.
The bytecode is a binary file that contains the execution program and consists of a sequence of operation codes or data pairs. The service provides functions of querying, adding, modifying and deleting data and the like for the user.
