javascript - Ajax can not send a request other than GET -

i can not. 4 days have been struggling send data ajax using different method , can not advise. create project in spring boot. have created mapped address controller

@putmapping(value = "/changeemail") public boolean changeemail(     @requestbody changeemaildto changeemaildto ) {     system.out.println("email: " + changeemaildto.getemail());     return true; } 

this controller supposed accept email address sent ajaxa

function changeemail() {     console.log("event");     $.ajax({         type: 'put',         url: '/changeemail',         data: {             email: $('#email').val()         },         success: function (result) {             console.log('function');         }     }); } 

however, effect in console crashes me

put http://localhost:8080/signin net::err_too_many_redirects send    @   jquery-3.2.1.min.js:4 ajax    @   jquery-3.2.1.min.js:4 changeemail @   settings.js:58 submithandler   @   settings.js:52 d   @   jquery.validate.min.js:4 (anonymous) @   jquery.validate.min.js:4 dispatch    @   jquery-3.2.1.min.js:3 q.handle    @   jquery-3.2.1.min.js:3 

the dto has 1 field

public class changeemaildto {     @isvalidemail     @existsemail(ifexistsreturn = false)     @getter @setter private string email; } 

after trying send data via ajax, sends me error controller

@controller public class pagenotfoundcontroller implements errorcontroller{     @requestmapping("/error")     public modelandview showpageerror() {         return new modelandview("redirect:/signin");     }      @override     public string geterrorpath() {         return "/error";     } } 

screen browser tool send , receive: https://zapodaj.net/f1b8ed0b2a16b.png.html mentioned, controller can correctly pick query ajax only. every time flips on error controller. additionally, if wanted send data directly form, there no problem query. ajax divert, not know.
