[FIXED] Why can Spring Data not find suitable converter for UDT?

Issue

I defined a UDT POJO class as follows

@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@UserDefinedType("address_type")
public class Address {
    
@Column("address_line")
@CassandraType(type = Name.TEXT)
private String addressLine;
@Column("postal_code")
@CassandraType(type = Name.TEXT)
private String postalCode;
@Column
@CassandraType(type = Name.TEXT)
private String city;

}

and also added this UDT definition on my keyspace for cassandra. My Entity with which I defined my UDT fields is

@Table("customer_model")
@Getter
@Setter
public class CustomerModel {

@PrimaryKey
private Integer id ;

@Column("company_name")
private String companyName;

@Column("company_email")
private String companyEmail;

@Column("tax_id")
private String taxId;

@Column("billing_address")
@CassandraType(type = Name.UDT,userTypeName = "address_type")
private Address billingAddress;

@CassandraType(userTypeName = "address_type", type = Name.UDT)
@Column("shipping_address")
private Address shippingAddress;
 }

When I try to make basic CRUD operations I get following Exception ,

No converter found capable of converting from type [models.udt.Address] to type [com.datastax.oss.driver.api.core.data.UdtValue]

I tried to add Custom Converter implementations to no avail. How to make spring find suitable converters for my POJO UDT to Cssandra UDT type?

Solution

Similar problem was encountered here. How-to-use-userdefinedtypes Somehow when you annotate your UDT POJO with @UserDefinedType , there is no need to annotate them again with @CassandraType while using them as entity class fields.
