There is no way to save/update/get/ PGpoint object directly,
Then you have to create your own user type for supporting PGpoint in order to convert it, before this is saved, UserType is a class of Hibernate which allows to create custom type in order to convert it before to save on database.
Here is code that you need to implement:
First: Need to create a class that implements of UserType:
public class PGPointType implements UserType {
@Override
public int[] sqlTypes() {
return new int[]
{
Types.VARCHAR
};
}
@SuppressWarnings("rawtypes")
@Override
public Class<PGpoint> returnedClass() {
return PGpoint.class;
}
@Override
public boolean equals(Object obj, Object obj1) {
return ObjectUtils.equals(obj, obj1);
}
@Override
public int hashCode(Object obj) {
return obj.hashCode();
}
@Override
public Object nullSafeGet(ResultSet resultSet, String[] names, SharedSessionContractImplementor sharedSessionContractImplementor, Object o) throws SQLException {
if (names.length == 1) {
if (resultSet.wasNull() || resultSet.getObject(names[0]) == null) {
return null;
} else {
return new PGpoint(resultSet.getObject(names[0]).toString());
}
}
return null;
}
@Override
public void nullSafeSet(PreparedStatement statement, Object value, int index, SharedSessionContractImplementor sharedSessionContractImplementor) throws SQLException {
if (value == null) {
statement.setNull(index, Types.OTHER);
} else {
statement.setObject(index, value, Types.OTHER);
}
}
@Override
public Object deepCopy(Object obj) {
return obj;
}
@Override
public boolean isMutable() {
return Boolean.FALSE;
}
@Override
public Serializable disassemble(Object obj) {
return (Serializable) obj;
}
@Override
public Object assemble(Serializable serializable, Object obj) {
return serializable;
}
@Override
public Object replace(Object obj, Object obj1, Object obj2) {
return obj;
}
}
Second: Need to add on entity header @TypeDef annotation, add a name and the PGPointType that you created it and on some field header of type PGpoint, add @Type annotation with the name that you created it:
@TypeDef(name = "type", typeClass = PGPointType.class)
@Entity
public class Entity {
@Type(type = "type")
private PGpoint pgPoint;
// Getters and setters
}
Kind regards.
