The controller
@ RequestMapping (value="https://bbs.csdn.net/searchbox", method=RequestMethod. POST)
Public List Searchbox (it request, HttpServletResponse response) {

response.setContentType("text/html; charset=utf-8");
/* set response headers allow ajax cross-domain access */
The response. SetHeader (" Access - Control - Allow - Origin ", "*");
/* asterisk said all foreign request can be accepted, */
Response. SetHeader (" Access - Control - Allow - the Methods ", "the GET and POST");

String formData=https://bbs.csdn.net/topics/request.getParameter (" formData ");

List Time3.=apiService searchbox (formData);
System. The out. Println (" search====="+ time3);
Return time3.

}
