Method and system for obtaining cross-system variables through JSP (Java Server Page) technology

Abstract

The invention relates to a method and a system for obtaining cross-system variables through a JSP technology. The method for obtaining the cross-system variables through the JSP technology comprises step 1, partitioning a variable providing system and a variable obtaining system in the same weblogic domain for providing the cross-system variables and obtaining the cross-system variables respectively; step 2, generating a first JSP page in the variable providing system and defining variables transmitted through a cross-system as JSON format (JavaScript Object Notiation) in the first JPS page; step 3, generating a second JSP page in the variable obtaining system, and agreeing on that the second JSP page can receive variables of the JSON format through an AJAX (Asynchronous JavaScript and XML) technology; step 4, sending a variable obtaining request to the variable providing system through the variable obtaining system, obtaining and parsing needed variables from the first JSP page and displaying the variables on the second JSP page. According to the method and the system for obtaining the cross-system variables through the JSP technology, the jsp pages are confirmed between different systems, json data is obtained through an ajax mode, accordingly, the data variables can be obtained, the number of times of service calling is reduced, the system speed is improved, and data transmission no longer has any timeliness restriction.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a system for acquiring cross-system variables through JSP technology. Background technique [0002] At present, if the system needs to display or obtain the information of different database user tables, it mainly obtains the data by calling the WebService service, and then displays it on the page. [0003] At present, the following technical points are mainly used when building components and using webservice services: [0004] 1.XML: A standard method for describing data. [0005] 2. SOAP: A protocol for information exchange. [0006] 3.WSDL: Web Services Description Language. [0007] 4. UDDI (Universal Description, Discovery and Integration): Universal Description, Discovery and Integration, which is a platform-independent, XML-based protocol for describing business on the Internet. [0008] Based on the above four technical points, for a small amount o...

Problems solved by technology

[0010] For example, system A only needs to transmit the information of the user's name, and transmits the message to system B in the form of XML, but system B accepts the message of SOAP by default, so it needs to convert from it, which is a waste of resources and time

[0011] 2. Congestion occurs when the service is called, resulting in failure to obtain the service

[0013] Therefore, it can be seen that although the Webservice method is widely used, on the basis of a small amount of data acquisition, from the perspective of data acquisition, the format of the message transmitted by the application between each system is not the same, and it is necessary to establish an application integration platform for unified transformation Message, this increases the operation steps and increases the risk, and from the perspective of cost, increasing the service will increase the burden on the server, which will require server performance, which will also increase the cost
