Multiple Beans of MongoTemplate with spring boot data mongodb

At first i used MongoTemplate without Configuration,
just made @Autowired and spring makes one default instanse based on properties from my application.yml
properties was like: 

spring:
  profiles: default
  data:
    mongodb:
      uri: mongodb://localhost:27017/myDbName

Now i need too write in two different database, i desided to create MongoConfig class
Example i found here Example

public abstract class AbstractMongoConfig {

private String host;

private int port;

private String database;

//here is Getters and Setters...

public MongoDbFactory mongoDbFactory() throws Exception {
    return new SimpleMongoDbFactory(new MongoClient(host, port), database);
}

abstract public MongoTemplate getMongoTemplate() throws Exception;
}

And:

@Configuration
@ConfigurationProperties(prefix = "primary.mongodb")
public class CommonMongoConfig
        extends AbstractMongoConfig {
    @Primary
    @Override public @Bean(name = "primaryMongoTemplate")
    MongoTemplate getMongoTemplate() throws Exception {
        return new MongoTemplate(mongoDbFactory());
    }
}

Second one:

@Configuration
@ConfigurationProperties(prefix = "second.mongodb")
public class SecondaryMongoConfig
        extends  AbstractMongoConfig {
    @Override public @Bean(name = "secondMongoTemplate")
    MongoTemplate getMongoTemplate() throws Exception {
        return new MongoTemplate(mongoDbFactory());
    }
}

Then i changed application.yml to:

spring:
  profiles: default
primary:
  mongodb:
    host: localhost
    port: 27017
    database: myDbName
second:
  mongodb:
    host: localhost
    port: 27017
    database: myDbName2

When i run application, it says me 

IllegalArgumentException:Could not resolve placeholder 'spring.data.mongodb.uri' in string value "${spring.data.mongodb.uri}"

of course, i deleted it, because i dont need it any more!
Why so?
Then i tried add it back. 

spring:
  profiles: default
  data:
    mongodb:
      uri: mongodb://localhost:27017/fake #notUsedActually
vkad:
  mongodb:
    host: localhost
    port: 27017
    database: myDbName
gap:
  mongodb:
    host: localhost
    port: 27017
    database: myDbName2

And it works! But dont used!
MongoTemplate beans creates right, depends on my prefix properties, its good.
But why i cant delete this for now? ${spring.data.mongodb.uri}
Mb im doing smth wrong ?

Stacktrace with commented property data.mongodb.uri.

DatabaseConfig

If you look at the error message:

Error creating bean with name 'databaseConfig': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.data.mongodb.uri' in string value "${spring.data.mongodb.uri}"

I suspect you have a class named DatabaseConfig in which you are yourself injecting the property with @Value("${spring.data.mongodb.uri}");

Remove this and it will work!
