I have a User bean with a property address. I have implemented custom converter for the User and the Address class and configured the same in spring XML. The converter for User is getting called every time I save User object. But, converter for Address is not getting called while saving the User and it throwing can't serialize class com.mkyong.model.Address.

Here is my class structure and Xml config:

User Class:

package com.mkyong.model;


import java.util.Map;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "person")
public class User 

 @Id
 private String id;

 String username;

 String password;

 Address address;

 Map data;

 public String getId() 
 return id;
 

 public void setId(String id) 
 this.id = id;
 

 public String getUsername() 
 return username;
 

 public void setUsername(String username) 
 this.username = username;
 

 public String getPassword() 
 return password;
 

 public void setPassword(String password) 
 this.password = password;
 

 public Address getAddress() 
 return address;
 

 public void setAddress(Address address) 
 this.address = address;
 

 public Map getData() 
 return data;
 

 public void setData(Map data) 
 this.data = data;
 

 public User(String username, String password) 
 super();
 this.username = username;
 this.password = password;
 

 @Override
 public String toString() 
 return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
 

Address class :

package com.mkyong.model;

import java.io.Serializable;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "address")
public class Address implements Serializable 
 /**
 * 
 */
 private static final long serialVersionUID = 2310280839505243479L;
 String city;
 String dist;
 String state;

 public Address(String city, String dist, String state) 
 super();
 this.city = city;
 this.dist = dist;
 this.state = state;
 

 public String getCity() 
 return city;
 

 public void setCity(String city) 
 this.city = city;
 

 public String getDist() 
 return dist;
 

 public void setDist(String dist) 
 this.dist = dist;
 

 public String getState() 
 return state;
 

 public void setState(String state) 
 this.state = state;
 

 @Override
 public String toString() 
 return "Address [city=" + city + ", dist=" + dist + ", state=" + state + "]";
 

spring configuration:

<mongo:mongo host="127.0.0.1" port="27017" />
 <mongo:db-factory dbname="springbootdb" />

 <mongo:mapping-converter id="mongoConverter">
 <mongo:custom-converters base-package="com.mkyong.model">
 <mongo:converter>
 <bean class="com.mkyong.converter.UserConverter" />
 </mongo:converter>
 <mongo:converter>
 <bean class="com.mkyong.converter.AddressConverter" />
 </mongo:converter>
 </mongo:custom-converters>
 </mongo:mapping-converter>

 <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
 <constructor-arg name="mongoConverter" ref="mongoConverter" />
 <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
 </bean>

User Converter :

package com.mkyong.converter;

import org.springframework.core.convert.converter.Converter;
import com.mkyong.model.User;
import com.mongodb.BasicDBObject;
import com.mongodb.DBObject;

public class UserConverter implements Converter<User, DBObject> 

 @Override
 public DBObject convert(User user) 
 DBObject dbObject = new BasicDBObject();
 dbObject.put("_id", user.getId());
 dbObject.put("_address", user.getAddress());
 System.out.println("called !!!!!");
 return dbObject;
 

Address Converter :

package com.mkyong.converter;

import org.springframework.core.convert.converter.Converter;
import com.mkyong.model.Address;
import com.mkyong.model.DecimalNumber;
import com.mkyong.model.User;
import com.mongodb.BasicDBObject;
import com.mongodb.DBObject;

public class AddressConverter implements Converter<Address, String> 

 @Override
 public String convert(Address user) 
 System.out.println("Not called!!!");
 return user==null ? null : user.toString();
 

I am very new to spring mongodb. Any help is greatly appreciated!
