Can not set java.lang.Integer field ...User.id to java.lang.Integer exception in Hibernate -

i building restful service hibernate jersey , spring on java , realized relationships between entities should without including instance of classes, identifiers (foreign keys). have exceptions when try query entities. have following entities:

@entity @javax.persistence.table(name = "manager_user") public class manageruser extends user {      @manytoone(targetentity = shopadminuser.class)     private integer shopadminuserid; //... }   @entity @javax.persistence.table(name = "shop_admin_user") public class shopadminuser extends user {      @lob     private string contactdata;      public string getcontactdata() {         return contactdata;     }      public void setcontactdata(string contactdata) {         this.contactdata = contactdata;     } }   @entity @inheritance(strategy= inheritancetype.table_per_class) public abstract class user {      @id     @generatedvalue(strategy = generationtype.table)     private integer id;      private string firstname;     private string lastname;      @temporal(temporaltype.date)     private date dob;      @enumerated(enumtype.string)     private gender gender;      @column(unique = true, nullable = false)     private string email;     @column(nullable = false)     private string password;      @lob     private string personaldata;      @onetoone(targetentity = photo.class)     private integer photoid;  //...getters , setters } 

and getting exception in next method:

@transactional(readonly = true) public list<manageruser> getbyshopadminuserid(integer id) {     session session = sessionfactory.getcurrentsession();     list managerusers = session.createquery(             "from manageruser m m.shopadminuserid = :shopadminuserid")             .setparameter("shopadminuserid", id).list();     return managerusers; }

what doing wrong? me)

i got seem question.now solve it.it's simple. code-->

@manytoone(targetentity = shopadminuser.class) private integer shopadminuserid; 

should

@manytoone(targetentity = shopadminuser.class) @joincolumn(name="shopadminuserid" references...=""(i forget how spell)) private shopadminuser shopadminuser; 

and this:

@onetoone(targetentity = photo.class) private integer photoid; 

should

 @onetoone(targetentity = photo.class) @joincolumn(name="photoid" references...=""(i forget how spell)) private photo photo; 

because hibernate auto converse class int or else
