Passing json object to spring mvc controller using Ajax -


i trying send json via ajax request spring mvc controller without success. json string has following form:

{"books":     [{'author':'murakami','title':'kafka on shore'},{'author':'murakami','title':'norwegian wood'}]}

the controller parses json wraps through java bean:

class books{    list <map<string, string>> books;    //...get & set method of bean }

the controller method has following form:

    @requestmapping(method = { requestmethod.get, requestmethod.post }, value = "/checkbook.do") public modelandview callcheckbook(         @requestbody books books){....}

unfortunately not work, following error when invoking method: "null modelandview returned dispatcherservlet name..."

where getting wrong? thank in advance! regards

create model class

class books { private string author; private string title; // gets , sets }

and create wrapper class this

class bookwrapper{ private list<books> books; // name should matches json header }

now in controller

@requestmapping(method = { requestmethod.get, requestmethod.post }, value = "/checkbook.do") public modelandview callcheckbook(         @requestbody bookwrapper books){....}

in ajax call create seralizearray of forum give json object , bind wrapper class
