HTTP send and receive XML requests under Spring MVC

HTTP send and receive XML requests under Spring MVCThis article describes how to send and receive XML requests through HTTP, in conjunction with the Swagger plug-in, under the Spring MVC Framework. 1, through the control to write, receive the interface of the XML request,

Where @requestbody tags, mainly in the content of XML body to see the direct transfer of XML content

Where @requestheader store the head content in XML, mainly used for interface security verification

The first half verifies the interface, the latter part parses the XML data, and the XML can be parsed with dom4j.
The code is as follows: 2, Swagger Interface interface, user-friendly, the code is as follows: 3, through HTTP, send an XML request.

/* Translate parameter map to parameter date String */
