sql - Unable to convert between java.lang.Integer and BINARY.- Spring -

i have following dto use persist new records database

@entity(name = "user") public class user {  @id @column(name = "user_id") private long userid;  @column(name = "user_name") private string usernm;  @column(name = "years_active") private long years;  @manytoone(cascade = cascadetype.all) @joincolumn(name = "manager_id", insertable = false, updatable = false) private manager manager;  @column(name = "projects",insertable = false, updatable = false) private linkedhashmap<long, string> projects;  @column(name = "projects") private long projectid;  @column(name = "address") private address address;  //getters & setters  } 

ddl:

create table [dbo].[user] ( [user_id] int not null, [user_name] varchar(255) not null, [years_active] int not null, [manager_id] int not null, //fk manager table [projects] int not null,   //fk project table [address] int null,        //fk address table [modifiedby] varchar(255) not null, [modifiedts] datetime null) 

i have no problem persisting data table via form submission, when try retrieve entity object using spring repository:

user user = userrepo.findone(id); // id == long, passed through @controller method 

i consistently following error : unable convert between java.lang.integer , binary.

o.h.engine.jdbc.spi.sqlexceptionhelper   : unable convert between java.lang.integer , binary. o.h.e.internal.defaultloadeventlistener  : hhh000327: error performing load command :  org.hibernate.exception.dataexception: not read entity state resultset : entitykey[com.myapp.entities.user#3]
