@Document doesn't create a collection in spring boot application

问题

I have a simple spring boot rest application. Trying to create a collection using @Document annotation in spring data mongo db. I know spring framework creates a collection if the document is denoted with @Document annotation.

Entity

@Document("User")
public class User {
    @Id
    private String Id;
    @Field("firstName")
    @TextIndexed
    private String firstName;
    @Field("lastName")
    @TextIndexed
    private String lastName;
    private String address;

    public String getId() {
        return Id;
    }

    public void setId(String id) {
        Id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

properties

spring.data.mongodb.uri=mongodb://localhost:27017/Order

However, in the rest controller, it creates a collection on insert command, but still, it doesn't create a Text-index on insert.

@RestController
public class Controller {
    private MongoTemplate mongoTemplate;

    public Controller(MongoTemplate mongoTemplate) {
        this.mongoTemplate = mongoTemplate;
    }

    @GetMapping("/get")
    public String Get(){
        mongoTemplate.insert(new User());
        return "HelloWorld";
    }
}

Don't have any error in the console as well

I have to set implicitly to work

In application.properties file

spring.data.mongodb.auto-index-creation=true

Or application.yml file

spring:
  data:
    mongodb:
      auto-index-creation: true

Reference - Please use 'MongoMappingContext#setAutoIndexCreation(boolean)' or override 'MongoConfigurationSupport#autoIndexCreation()' to be explicit
