-

i have added new controller in spring mvc project , added annotations below ...but here while running project i'm getting 404 exception , in console i'm getting exception below ...i'm confused figure out issue...

here controller:

@controller @requestmapping("/escprojectprogstatuscontroller") public class escprojectprogstatuscontroller {     @autowired     escprojectprogstatusservice escprojectprogstatusservice;    @requestmapping(value = "/fetchunitnamedropdown")     public @responsebody string fetchunitnamedropdown(httpservletrequest request){         string strunitnames = "";         string strprojectid = request.getparameter("projectid")==null?"":request.getparameter("projectid");         try {             strunitnames = escprojectprogstatusservice.fetchunitnamefromprojectid(strprojectid);         } catch (exception e) {               //logger.error(e);             throw e;         }         return strunitnames.tostring();     } }

service impl:

@service("escprojectprogstatusservices") @transactional public class escprojectprogstatusserviceimpl implements escprojectprogstatusservice {      @autowired     escprojectprogstatusdao escprojectprogstatusdao; @override     public string fetchunitnamefromprojectid(string strprojectid){         jsonarray jsonarr = new jsonarray();         jsonobject jsonobj = null;         list<projectunit> listprojectunit = null;         try{             listprojectunit = (list<projectunit>)escprojectprogstatusdao.fetchunitnamefromprojectid(strprojectid);             if(listprojectunit!=null){                 for(projectunit projectunit :listprojectunit){                     jsonobj = new jsonobject();                     jsonobj.put("unittype", projectunit.getunittype());                     jsonobj.put("unitname", projectunit.getunitname());                     jsonarr.add(jsonobj);                 }             }         }catch(exception e){             //logger.error(e);         }         return jsonarr.tostring();     } }

dao impl:

@repository("escprojectprogstatusdao") public class escprojectprogstatusdaoimpl implements escprojectprogstatusdao {     @autowired     private sessionfactory sessionfactory; @override     public list<projectunit> fetchunitnamefromprojectid(string strprojectid){         list<projectunit> listprojectunit = null;         try {             session session = sessionfactory.getcurrentsession();             criteria criteria = session.createcriteria(projectunit.class);             criteria.add(restrictions.eq("merchantproductid", strprojectid));             listprojectunit=criteria.list();         }catch(exception e){             //logger.error(e);         }         return listprojectunit;     } }
