Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of the main flow of an interaction method between different applications according to an embodiment of the present invention. It can be understood that different applications that interact with each other include, but are not limited to, applications written in Java, C language, python, PHP, C ++, and other languages, and specifically, the embodiments of the present invention will be described in detail by taking only a first application written in a first language as a Java application and a second application written in a second language as a Python application as an example.
As shown in fig. 1, the interaction method of the Java application and the Python application specifically includes the following steps:
In step S101, a Java application receives a service request, and generates a computing task according to the service request, where the computing task indicates a computing task identifier and an incoming parameter of the computing task.
Java applications include, but are not limited to, java Web applications, java App applications, and the like, and Python applications also include, but are not limited to, python Web applications, python App applications, and the like. Because the Java application is different from the development language adopted by the Python application, the format of the input parameters that can be supported when the Java application correspondingly executes the calculation task is not feasible, so before the Java application calls the Python application to execute the calculation task, that is, before the calculation task identifier is sent to the Python application, the Java application needs to make the input parameters of the calculation task conform to the parameter format required by the calculation of the Python application. In addition, when a database storing the input parameters of the computing task corresponding to a Java application such as a Java Web application has a database partition, a table partition, or the like, it is also necessary to obtain the input parameters of the corresponding computing task from one or more partitions or tables of the database.
Specifically, taking a Java application as an example, a Java Web application is taken as an illustration, a corresponding service request is generated according to a Web page request from a client, and when an abnormality occurs in the Java Web application when generating an incoming parameter of a computing task according to the Web page request, the abnormality can be sent to the client for display, so as to prompt a user or related personnel to generate the abnormality in the incoming parameter.
Step S102, the Java application sends the computing task identification to the Python application.
The Java application sends the computing task identification to the Python application through one or more of the following interfaces: restful, SOAP, RPC (remote procedure call) and HTTP. Specifically, still taking a Java application as a Java Web application and a corresponding Python application as a PythonWeb application as an example, encapsulating specific implementation codes of a Python algorithm through Web application frameworks such as flash, django and the like and providing a corresponding Restful interface for the outside such as the Java Web application and the like, so that the Java Web application calls the Python Web application through the Restful interface and transmits a computing task identifier corresponding to a computing task to be executed to the Python Web application.
Step S103, the Python application executes the calculation task using the input parameters of the calculation task according to the calculation task identifier, so as to generate a calculation result.
Preferably, the Python application uses a thread pool to select a thread for executing a received computing task for the computing task identification. That is, the Python application schedules threads for executing computing tasks through the thread pool, and when there are multiple computing tasks to be executed, the threads can be started simultaneously to perform concurrent processing; when a specific calculation task is started to be executed, acquiring the input parameters of the calculation task, checking the format, the size and the like of the input parameters of the calculation task, and executing the calculation task by calling a corresponding Python algorithm in the checking process; in addition, if the verification of the incoming parameter fails, an error message is sent to the Java application through a message queue or the like.
It is understood that the Java application may send the computing task identification and the incoming parameters of the computing task directly to the Python application without a message queue; the Python application may also perform the computing task using the received incoming parameters of the computing task to generate a computing result.
Preferably, the Java application stores the computing task identifier and the input parameters of the computing task in the message queue correspondingly, and sends the computing task identifier to the Python application; and the Python application acquires the input parameters of the calculation task from the message queue according to the calculation task identification, and executes the calculation task by using the input parameters of the calculation task to generate a calculation result.
Step S104, the Python application stores the calculation result and the calculation task identification in the message queue correspondingly, so that the Java application obtains the calculation result corresponding to the calculation task from the message queue.
The problems of Java Web application and Python Web application interaction coupling, asynchronous processing, flow cutting and the like are solved through the message queue, and usable message queues include but are not limited to: redis, rabbitMQ, rocketMQ, activeMQ, kafka, etc.
Preferably, in the case that an abnormality occurs when the Python application executes the computing task, the Python application stores the abnormality and the computing task identifier in the message queue in correspondence, so that the Java application can acquire a message of the computing task execution abnormality from the message queue according to the computing task identifier, so as to timely perform processing such as abnormality analysis on the executing task with the abnormality.
Based on the interaction method of the Java application and the Python application in the embodiment, interaction between the Java application and the Python application is realized through Restful, SOAP, RPC and an HTTP interface; meanwhile, information such as an incoming parameter, a calculation result, calculation abnormality and the like of a calculation task during interaction between Java application and Python application is transmitted through a message queue, so that asynchronous communication between the Java application and the Python application is realized, and interaction between the Java application and the Python application is decoupled; in addition, the scheduling of the Python application to the threads in the thread pool realizes the concurrent processing of a plurality of computing tasks requested to be executed by the Java application, and improves the execution efficiency of the computing tasks. It can be understood that, in the embodiment of the present invention, only the first application written in the first language is a Java application, and the second application written in the second language is a Python application. But different applications for interaction by using the interaction method between different applications provided by the embodiment include, but are not limited to, applications written in languages such as Java, C language, python, PHP, C ++, and the like.
Referring to fig. 2, on the basis of the above embodiment, an interaction method of a Java application and a Python application is provided, which specifically includes the following steps:
In step S201, the Java application receives a service request, and generates a computing task according to the service request, where the computing task indicates a computing task identifier and an incoming parameter of the computing task.
In step S202, the Java application stores the computing task identifier and the input parameters of the computing task in the message queue correspondingly.
The Java application causes the incoming parameters of the computing task to conform to a parameter format required for the computation of the Python application before storing the computing task identification and the incoming parameters of the computing task in correspondence to the message queue. And when the Java application is a Java Web application and an exception occurs to enable the input parameters of the computing task to accord with the parameter format required by the computation of the Python application, sending the exception to the client for display.
Step S203, the Java application sends the computing task identifier to the Python application through one or more of the following interfaces: restful, SOAP, RPC and HTTP.
Step S204, the Python application obtains the input parameters of the computing task from the message queue according to the computing task identification.
In step S205, the Python application uses the input parameters of the calculation task to execute the calculation task to generate a calculation result.
The Python application uses a thread pool to select a thread for executing a received computing task for the computing task identification. In the case that an abnormality occurs when the Python application executes the computing task, the Python application stores the abnormality to the message queue corresponding to the computing task identification. Message queues that may be used include, but are not limited to: redis, rabbitMQ, rocketMQ, activeMQ, kafka, etc.
Step S206, the Python application stores the calculation result and the calculation task identifier in the message queue correspondingly.
Step S207, the Java application obtains the corresponding result of the computing task from the message queue according to the computing task identifier.
When the Java Web application obtains the corresponding result of the calculation task from the message queue, the Java Web application performs data cleaning and analysis on the calculation result, and returns the calculation result to the front-end page.
It can be understood that, in the embodiment of the present invention, only the first application written in the first language is a Java application, and the second application written in the second language is a Python application. But different applications for interaction by using the interaction method between different applications provided by the embodiment include, but are not limited to, applications written in languages such as Java, C language, python, PHP, C ++, and the like.

The Python application is further configured to store the calculation result and the calculation task identifier in the message queue in correspondence, so that the Java application obtains the calculation result corresponding to the calculation task from the message queue;
and the message queue is used for correspondingly storing the calculation result and the calculation task identifier.
Preferably, the Java application sends the computing task identification to the Python application through one or more of the following interfaces: restful, SOAP, RPC and HTTP.
Preferably, the Java application is further configured to store the computing task identifier and the input parameters of the computing task in the message queue correspondingly, and send the computing task identifier to the Python application;
The Python application is further configured to obtain an incoming parameter of the computing task from the message queue according to the computing task identifier, and execute the computing task using the incoming parameter of the computing task to generate a computing result
Preferably, the Java application sends the computing task identifier and the incoming parameters of the computing task to the Python application;
The Python application performs the computing task using the received incoming parameters of the computing task to generate a computing result.
