spring-data-jdbc readOnly

Question

I'm trying to make some field readOnly -> insert and update aka save() should not send that field to DB but the field should be populated with select.

@ReadOnlyProperty from org.springframework.data.annotation.ReadOnlyProperty does not do the trick.

versions: spring-boot: 2.2.0.RC1, spring-data-jdbc: 1.1.0.RELEASE, spring-data-commons: 2.2.0.RELEASE

db: MSSQL

spring-data-jdbc readOnly

Should it work and is there any other way to do it?

NOTE: please don't mix spring-data-jdbc with spring-data-jpa

import java.util.Set;
import org.springframework.data.annotation.Id;
import org.springframework.data.annotation.ReadOnlyProperty;
import org.springframework.data.relational.core.mapping.Column;
import org.springframework.data.relational.core.mapping.MappedCollection;

public class Organization {
    @Id
    private Long id;
    private String name;
    @Column("readOnlyProperty")
    @ReadOnlyProperty
    private String readOnlyProperty;
    @ReadOnlyProperty
    @MappedCollection
    private Set<Employee> employees;
}

import org.springframework.data.annotation.Id;

public class Employee {
    @Id
    private Long id;
    private String name;
}

@Test
public void insert() {
    // insert should not set readOnlyProperty
    Organization organization = new Organization("org1", "readOnly");
    Employee employee = new Employee("emp1");
    Set<Employee> employess = new HashSet<>();
    employess.add(employee);
    organization.setEmployees(employess);
    organizationRepository.save(organization);
}

LOG: Executing prepared SQL statement [INSERT INTO organization (name, readOnlyProperty) VALUES (?, ?)]

This is a bug. I created DATAJDBC-431 for it and it will probably fixed in the next service release.
