do not know how to do it with hsqldb… we have a MSSQL where multiple tables have combined PKs defined.
I added 2 classes which look similar to those we have for those tables with combined PKs.
If you need more information, I would need to create a new project based on SQL Server…
But I do not have the time for that this week.
Actually we got a workaround using JDBCTemplate, but would like to use the saveContext.
In our app the definition looks like this:
for the CompKey
package com.company.ckeydelsampl.entity.key;
import org.springframework.data.util.ProxyUtils;
import javax.persistence.*;
import java.util.Objects;
public class TestTableCompKey {
@Column(name = "PK1", nullable = false, unique = true)
private String PK1;
@Column(name = "PK2", nullable = false, unique = true)
private String PK2;
@Column(name = "PK3", nullable = false, unique = true)
private String PK3;
public String getPK1() {
return PK1;
}
public void setPK1(String PK1) {
this.PK1 = PK1;
}
public String getPK2() {
return PK2;
}
public void setPK2(String PK2) {
this.PK2 = PK2;
}
public String getPK3() {
return PK3;
}
public void setPK3(String PK3) {
this.PK3 = PK3;
}
@Override
public int hashCode() {
return Objects.hash(PK1,PK2,PK3);
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || ProxyUtils.getUserClass(this) != ProxyUtils.getUserClass(o)) return false;
TestTableCompKey entity = (TestTableCompKey) o;
return Objects.equals(this.PK1, entity.PK1) &&
Objects.equals(this.PK2, entity.PK2) &&
Objects.equals(this.PK3, entity.PK3);
}
}
