In practical application, the data format and the mode of exchange are diversified, the communication protocol is multiple, and the communication message and the file are more complex.

The server 105 may be a server providing various services, such as a background management server (for example only) providing support for a data conversion system operated by a user with the terminal devices 101, 102, 103. The background management server may analyze and perform other processing on the received data such as the task request to be converted, and feed back a processing result (for example, the converted data — only an example) to the terminal device.
The server 105 may register at least one service in the component container, for example, through at least one class loader; the server 105 may, for example, obtain a task to be converted, where the task to be converted includes data to be converted and at least one split task to be converted; the server 105 may determine at least one target service among the at least one service of the component container, for example, according to the at least one split task to be converted.

In the embodiment of the disclosure, when a user uploads at least one service created according to user requirements to a server by a client, the at least one service can be compressed to generate a class to be loaded compression package, and the class to be loaded compression package is uploaded to the server. After receiving at least one class compression packet to be loaded, the server side can compare the at least one class compression packet to be loaded with a plurality of class compression packets existing in the component container, and if the class compression packets existing in the component container exist in the at least one class compression packet to be loaded, the class compression packet to be loaded is filtered. Fig. 4 shows a schematic diagram of the filtering process according to step S304 in fig. 3. The class to be loaded may further include at least one compressed package, a third party package, and the like, and the class to be loaded may have a compressed package directory to record each compressed package. As shown in fig. 4, in step S402, a plurality of class compression packages to be loaded in the directory of the class compression packages to be loaded may be analyzed, and then compared with the class compression package set in the platform class loader, if included, step S404 is executed, otherwise, step S406 is executed to implement the filtering operation. The platform loader is connected with the component container, and operations such as searching and traversing can be performed in the component container.
In step S306, the filtered at least one class compression package to be loaded is loaded as at least one service by each class loader.
In step S308, a task to be converted is obtained, where the task to be converted includes data to be converted and at least one split task to be converted.

As shown in FIG. 5, the plug-in class loaders are isolated from each other and cannot pass parameters to each other (in the case of deserialization and deserialization), in which case the same class cannot be shared. In this embodiment, each class loader first searches for a class compression packet included in itself to obtain a partial service; searching for services in the component container through the platform type loader; and finally, searching the service by the system class loader to load and obtain at least one target service.
In step S312, the at least one target service is sequentially executed through a unified interface to convert the data to be converted.
FIG. 6 is a flow chart illustrating a method of data conversion in accordance with an exemplary embodiment. The data conversion method 60 provided by the embodiment of the present disclosure may include steps S602 to S306.
As shown in fig. 6, in step S602, at least one class compression package to be loaded for each class loader is obtained.
In step S604, at least one service tag class file and at least one service consumer in each class compression package to be loaded are registered as at least one service and at least one service agent, respectively.
Each file in the class compression package to be loaded contains a label, the label can comprise a service label class and a service consumer, and the service consumer is used for generating a dynamic proxy to search for services.
In step S606, a task to be converted is obtained, where the task to be converted includes data to be converted and at least one split task to be converted.
In step S608, the at least one target service agent is determined and invoked in the at least one service agent of the component container according to the at least one split task to be converted.
In step S610, the at least one target service is looked up by the at least one target service agent.
In step S612, the at least one target service is sequentially executed through a unified interface to convert the data to be converted.
According to the data conversion method provided by the embodiment of the disclosure, a common class compression packet is registered in the component container through filtering operation during service registration, so that the service can be loaded through a uniform interface, and the functions of directly performing parameter assignment among all services and calling the method can be achieved; meanwhile, the operation of repeated class compression packets can be reduced, and the system resource occupation rate is reduced.
According to the data conversion method provided by the embodiment of the disclosure, when the package name of the class compression package in the plug-in class loader is the same as that of the class compression package in the component container, but the version of the class compression package is the same, the class compression package in the plug-in class loader can be loaded through the plug-in class loader first, so as to facilitate version upgrade of the service.

A readable storage medium may also be any readable medium that is not a readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a readable storage medium may be transmitted using any appropriate medium, including but not limited to wireless, wireline, optical fiber cable, RF, etc., or any suitable combination of the foregoing.
Program code for carrying out operations for the present disclosure may be written in any combination of one or more programming languages, including an object oriented programming language such as Java, C + + or the like and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computing device, partly on the user's device, as a stand-alone software package, partly on the user's computing device and partly on a remote computing device, or entirely on the remote computing device or server. In the case of a remote computing device, the remote computing device may be connected to the user computing device through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computing device (e.g., through the internet using an internet service provider).
The computer readable medium carries one or more programs which, when executed by a device, cause the computer readable medium to perform the functions of: registering, by the at least one class loader, the at least one service in the component container; acquiring a task to be converted, wherein the task to be converted comprises data to be converted and at least one split task to be converted; determining at least one target service in at least one service of the component container according to the at least one split task to be converted; and sequentially executing the at least one target service through a uniform interface so as to convert the data to be converted.
