Mongo Template querying the wrong collection - spring

Question

I have a mongodb springboot application that is connected to 2 different databases, that have the same collection names and database names but different uris.
Here is my application.properties
spring.data.mongodb.uri = uri
spring.data.mongodb.secondDB.uri = uri
spring.data.mongodb.database = database_name
spring.data.mongodb.secondDB.database = database_name
My AppConfiguration file
#Configuration
public class MultipleMongoConfig {
#Primary
#Bean(name = "newdb1Properties")
#ConfigurationProperties(prefix = "spring.data.mongodb")
public MongoProperties getNewDb1Props() throws Exception {
return new MongoProperties();
}
#Bean(name = "newdb2Properties")
#ConfigurationProperties(prefix = "spring.data.mongodb.secondDB")
public MongoProperties getNewDb2Props() throws Exception {
return new MongoProperties();
}
#Primary
#Bean(name = "newdb1MongoTemplate")
public MongoTemplate newdb1MongoTemplate() throws Exception {
return new MongoTemplate(newdb1MongoDatabaseFactory(getNewDb1Props()));
}
#Bean(name ="newdb2MongoTemplate")
public MongoTemplate newdb2MongoTemplate() throws Exception {
return new MongoTemplate(newdb2MongoDatabaseFactory(getNewDb2Props()));
}
#Primary
#Bean
public MongoDatabaseFactory newdb1MongoDatabaseFactory(MongoProperties mongo) throws Exception {
return new SimpleMongoClientDatabaseFactory(
mongo.getUri()
);
}
#Bean
public MongoDatabaseFactory newdb2MongoDatabaseFactory(MongoProperties mongo) throws Exception {
return new SimpleMongoClientDatabaseFactory(
mongo.getUri()
);
}
Then I set up config files for each data source
#Configuration
#EnableMongoRepositories(basePackages = {"com.example.app.firstDatabse.Repository"},
mongoTemplateRef = "newdb1MongoTemplate"
)
public class NewDb1Config {
}
and
#Configuration
#EnableMongoRepositories(basePackages = {"com.example.app.secondDatabse.Repository"},
mongoTemplateRef = "newdb2MongoTemplate"
)
public class NewDb1Config {
}
For Model I have the following
#AllArgsConstructor
#NoArgsConstructor
#ToSting
#Document(collection = "coll")
public class FirstModel{
#Id
public String id;
#Field("f_name")
public String firstName;
#Field("l_name")
public String lastName;
#Field("age")
public int age;
#Field("gender")
public String gender;
}
and my second Model is the same
#AllArgsConstructor
#NoArgsConstructor
#ToSting
#Document(collection = "coll")
public class SecondModel{
#Id
public String id;
#Field("f_name")
public String firstName;
#Field("l_name")
public String lastName;
#Field("age")
public int age;
#Field("gender")
public String gender;
}
My controller
#ResController
#RequestMapping("/controller")
public class Controller{
#Autowired
private FirstDataabseRepository repo;
#Autowired
private SecondDataabseRepository repo;
#Resource
private MongoTemplate mongoTemplate;
#RequestMapping("/findByName")
public List<SecondModel> findByName(){
Criteria criteria = new Criteria();
criteria = Criteria.where("f_name").is("John");
Query q = new Query(criteria);
List<SecondModel> results = mongoTemplate.find(q,SecondModel.class);
return results;
}
}
So the results show the results of the first collection not the second one. What do I need to do for mongoTemplate to query the second collection not the first one.

Solution
I have to add a qualifier and have a mongoTemplate for each collection
#ResController
#RequestMapping("/controller")
public class Controller{
#Autowired
private FirstDataabseRepository repo;
#Autowired
private SecondDataabseRepository repo;
#Resource
#Qualifier(value="newdb1MongoTemplate")
private MongoTemplate mongoTemplate;
#Resource
#Qualifier(value="newdb2MongoTemplate")
private MongoTemplate mTemplate;
#RequestMapping("/findByName")
public List<SecondModel> findByName(){
Criteria criteria = new Criteria();
criteria = Criteria.where("f_name").is("John");
Query q = new Query(criteria);
List<SecondModel> results = mTemplate.find(q,SecondModel.class);
return results;
}
}
