Also I am trying following config of mongotemplate
Please advise if correct
public MongoTemplate messagingMongoTemplate() throws Exception {
MongoTemplate mongoTemplate=null;
try {
DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory);
MappingContext mappingContext = new MongoMappingContext();
MappingMongoConverter mappingMongoConverter = new MappingMongoConverter(dbRefResolver,mappingContext);
CustomConversions customConversions = new CustomConversions(Arrays.asList(new MongoDbMessageBytesConverter()));
mappingMongoConverter.setCustomConversions(customConversions);
mongoTemplate=new MongoTemplate(mongoDbFactory,mappingMongoConverter);

Starting with version 3.0 it is recommended to use ConfigurableMongoDbMessageStore as that provides more options for customization, including a Converter for Message.
Out-of-the-box Spring Integration provides MongoDbMessageBytesConverter, which has become public since 4.2.10 and is used by default if there is no any external customization for the ConfigurableMongoDbMessageStore.
