spring - Bad deserialize with jackson -

-

i try call url accept list.

data sent 

{"contactavailableidlist":["1"],"contactidlist":["2","3"]}   method on server @requestmapping(value = "/lodgers/{lodgerid}/associate/dissociate/contact", method = requestmethod.put) public void associatelodgerandcontact(@pathvariable("lodgerid") long lodgerid, @requestbody @valid final list<long> contactidlist, @requestbody @valid final list<long> contactavailableidlist) {     lodgerservice.associatedissociatelodgerandcontact(lodgerid, contactidlist, contactavailableidlist); }

"{"timestamp":1445958336633,"status":400,"error":"bad request","exception":"org.springframework.http.converter.httpmessagenotreadableexception","message":"could not read document: can not deserialize instance of java.util.arraylist out of start_object token\n @ [source: java.io.pushbackinputstream@5a1edae4; line: 1, column: 1]; nested exception com.fasterxml.jackson.databind.jsonmappingexception: can not deserialize instance of java.util.arraylist out of start_object token\n @ [source: java.io.pushbackinputstream@5a1edae4; line: 1, column: 1]","path":"/rest/lodgers/1/associate/dissociate/contact"}"

well not sure, if can accept more requestbodies @ once.

standard way have class

public class contact{   list<long> contactidlist;   list<long> contactavailableidlist; }

and accept as

@requestbody @valid contact contact

also receiving array of string , try save them array of long. not sure either, if jackson tries implicitly transform string elements of array long in such case.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
