#generatedvalue not working, still asking to manually assign id - spring

Question

I'm learning spring-hibernate and trying to get my web service working, but now i'm stuck with this situation. My service for getting the data work well but when i try to post this condition happen :
i already use #generated value annotation
trying modif it's type like : GenerationType.SEQUENCE, IDENTITY, etc (none of them work either)
So far my best guess, so this is my code
This is my model class (part of it) the other is typical like email, phone, etc. And it dont have any relation to another table, only 1 table on my DB btw i use ms sql server
#Entity
#Table(name="Patient")
#SuppressWarnings("serial")
public class Patient implements Serializable {
#Id
#GenericGenerator(name = "guidGenerator", strategy = "guid")
#GeneratedValue( generator= "guidGenerator")
#Column(name = "PatientGUID", columnDefinition="uniqueidentifier")
private String patientGuid;
private String firstName;
private String lastName;
public String getPatientGuid() {
return patientGuid;
}
public void setPatientGuid(String patientGuid) {
this.patientGuid = patientGuid;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
Edit : My hbm file
<hibernate-mapping package="training.model">
<class name="Patient" table="Patient">
<id name="patientGuid" type="string">
<column name="PatientGUID" />
<generator class="assigned" />
</id>
<property name="practiceGuid" type="string">
<column name="PracticeGUID" sql-type="varchar" length="38" not-null="true" />
</property>
<property name="firstName" type="string">
<column name="FirstName" sql-type="varchar" length="30" not-null="true" />
</property>
<property name="lastName" type="string">
<column name="LastName" sql-type="varchar" length="30" not-null="true" />
</property>
</class>
</hibernate-mapping>
My table detail which i believed caused this problim is : PatientGUID and it's type is UNIQUEIDENTIFIER, when i execute my webservice and request POST method to post my patient i got an error, which is :
ids for this class must be manually assigned before calling save()
So guys i really need help, what did i do wrong or what did i miss? If you need any more detail on my code just leave a comment, thanks

Answer 1

There is no guid strategy in hibernate, there is however uuid. Following should work.
#GenericGenerator(name = "guidGenerator", strategy = "uuid2")
