spring - Hibernate - No value specified for parameter -

i have entity class mapped this:

@entity @table(name = "configuration") @xmlrootelement @xmlaccessortype(xmlaccesstype.field) public class jsonconfiguration implements jsonserializable, serializable { private static final long serialversionuid = 1l;  @id @notnull @jsonproperty("_id") private integer id;  @jsonproperty("config") @notnull @type(type = "jsontype") private string config;  public jsonconfiguration(integer id, string config) {     this.id = id;     this.config = config; }  public jsonconfiguration(){      super(); }  public integer getid() {     return id; }  public void setid(integer id) {     this.id = id; }  public string getconfig() {     return config; }  public void setconfig(string config) {     this.config = config; } } 

each time i'm trying update or insert same error:

here typedef config column:

public class jsonusertype extends abstractusertype { @override public int[] sqltypes() {     return new int[] { types.java_object}; }  @suppresswarnings("rawtypes") @override public class returnedclass() {     return string.class; }  @override public object nullsafeget(resultset resultset, string[] strings, sessionimplementor sessionimplementor, object o) throws hibernateexception, sqlexception {     if(resultset.getstring(strings[0]) == null){         return null;     }     return resultset.getstring(strings[0]); }  @override public void nullsafeset(preparedstatement preparedstatement, object o, int i, sessionimplementor sessionimplementor) throws hibernateexception, sqlexception {     if (o == null) {         preparedstatement.setnull(i, types.other);         return;     } }  } 

and class extends:

abstract class abstractusertype implements usertype { @override public object assemble(serializable cached, object owner) {     return cached; }  @override public object deepcopy(object value) {     return value; }  @override public serializable disassemble(object value) {     return (serializable)value; }  @override public boolean equals(object x, object y) {     return (x == y) || (x != null && y != null && (x.equals(y))); }  @override public int hashcode(object x) {     return x.hashcode(); }  @override public boolean ismutable() {     return false; }  @override public object replace(object original, object target, object owner) {     return original; }  } 

can please explain why happening? started after migrated spring 4 , hibernate 4. hibernate logs provided below seems can't bind firs parameter, can't figure out why.
