my controller this

 package in.ac.nitk.tas.controller; import in.ac.nitk.tas.service.homeservice; import in.ac.nitk.tas.vo.uservo;  import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.controller; import org.springframework.ui.modelmap; import org.springframework.web.bind.annotation.requestbody; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.requestmethod;         @controller         @requestmapping("/home")         public class homecontroller {              @autowired             private homeservice homeservice;              @requestmapping("/gethomepage") public string gethomepage() {      system.out.println("in home");     return "login";  }              @requestmapping(value = "/login", method = requestmethod.post)             public              string login(@requestbody final uservo uservo,final modelmap map) {                 string view ="login";                          return view;             }          } 

my uservo is

/**  *   */ package in.ac.nitk.tas.vo;  import java.io.serializable;  /**  * @author nitk  *  */ public class uservo implements serializable {      /**      *       */     private static final long serialversionuid = 1l;     private string username;     private string password;     private string usertype;       /**      * @return usertype      */     public string getusertype() {         return usertype;     }     /**      * @param usertype usertype set      */     public void setusertype(string usertype) {         this.usertype = usertype;     }     /**      * @return username      */     public string getusername() {         return username;     }     /**      * @param username username set      */     public void setusername(string username) {         this.username = username;     }     /**      * @return password      */     public string getpassword() {         return password;     }     /**      * @param password password set      */     public void setpassword(string password) {         this.password = password;     }    }
