This is an jsp file about key query, which accepts the data of the parent file and encrypts it, puts it into the Map collection, and submits it to the xdoc file through the form form. However, this approach is to meet the requirements of the company, the content of the framework is cumbersome; The next article introduces a simple and common approach that doesn't require much of an environment to build.
