A method and system for obtaining cross-system variables through jsp technology

Abstract

The present invention relates to a method and system for obtaining cross-system variables through JSP technology, said method comprising: step 1, in the same weblogic domain, divide variable providing system and variable obtaining system, respectively for providing and obtaining cross-system variables; 2. Generate a first JSP page in the variable providing system, and define the variable passed across the system as JSON format in the first JSP page; Step 3, generate a second JSP page in the variable obtaining system , and agree that the second JSP page can receive variables in JSON format through AJAX technology; step 4, the variable acquisition system initiates a variable acquisition request to the variable providing system, acquires and parses the required variables in JSON format from the first JSP page, and displayed on the second JSP page. The invention confirms jsp pages between different systems, acquires json data through ajax, thereby acquires data variables, reduces service calling times, improves system speed, and data transmission is no longer time-limited.

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...

AI Technical Summary

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
