Spring-cassandra UDT data insertion

Can anyone help me learn how to insert Cassandra UDT data using the Spring

POJO class ?

I created one POJO class to display the Cassandra table and created another class for the Cassandra UDT, but when I inserted the main POJO class that displays the Cassandra table it did not recognize the other POJO class (Cassandra UDT map). I also wrote an annotation for each class and for each class object.

Here is my POJO class: -

package com.bdbizviz.smb.model.entity;

import org.springframework.cassandra.core.PrimaryKeyType;
import org.springframework.data.cassandra.mapping.PrimaryKeyColumn;
import org.springframework.data.cassandra.mapping.Table;

import com.bdbizviz.smb.cassandra.udt.CoverPhoto;
import com.bdbizviz.smb.cassandra.udt.Location;
import com.bdbizviz.smb.cassandra.udt.MailingAddress;
import com.bdbizviz.smb.cassandra.udt.Reference;
import com.bdbizviz.smb.cassandra.udt.RestaurantServices;
import com.bdbizviz.smb.cassandra.udt.RestaurantSpecial;
import com.bdbizviz.smb.cassandra.udt.VoipInfo;
import com.datastax.driver.mapping.annotations.Frozen;


@Table("source")
public class Sources {


Integer likes;
Integer followers;
Integer rating;
String last_processedtime;
String filter_str;
String filter_type;
String category;

@PrimaryKeyColumn(ordinal=0,type=PrimaryKeyType.PARTITIONED)
String admin;

@PrimaryKeyColumn(ordinal=1,type=PrimaryKeyType.CLUSTERED)
String name;

@PrimaryKeyColumn(ordinal=2,type=PrimaryKeyType.CLUSTERED)
String source;

@PrimaryKeyColumn(ordinal=3,type=PrimaryKeyType.CLUSTERED)
Integer id;

@PrimaryKeyColumn(ordinal=4,type=PrimaryKeyType.CLUSTERED)
String type;

Integer delete_flag;
Integer evaluated;

@Frozen
Reference fb_reference_id_name ;

@Frozen
MailingAddress fb_mailingaddress;

@Frozen
CoverPhoto fb_coverphoto ;

@Frozen
VoipInfo fb_voipinfo;

@Frozen
RestaurantServices fb_restaurantservice;

@Frozen
RestaurantSpecial fb_restaurantspecialties;

@Frozen
Location fb_location;

/* Setter and Getter */
}

      

        
        
        
      

    

Another POJO class: -

package com.bdbizviz.smb.cassandra.udt;

import org.springframework.data.annotation.Persistent;
import com.datastax.driver.mapping.annotations.Field;
import com.datastax.driver.mapping.annotations.UDT;

@UDT(name = "reference" ,keyspace="smb")
public class Reference {

@Field(name="id")
String id ;

@Field(name="name")
String name;

/* Setter and Getter */
}
