This article introduces a simple example code of a jsp file about key query. Friends who need it can refer to it

This is a jsp file about key query, which accepts the data of the superior file and encrypts it. Process, put it into the Map collection, and submit it to the xdoc file through the form form; however, this approach is to meet the company's requirements, and the content of the framework is inevitably cumbersome; the next article will introduce a simple method that does not require too much construction. Common practice in multiple environments.
