I am now making a small demo through spring-boot+spring-mongo, which is the latest version. Now there is a problem that I cannot connect to other libraries in any way, only mongodb’s default test library. What is the reason?

Yml:

spring.data.mongodb.uri: mongodb://localhost:27017/mongo

In theory, this should be connected to the mongo library. My mongodb does not have permission authentication configured and does not require a password and user name.

gradle :

compile("org.springframework.boot:spring-boot-starter-data-mongodb")
 compile("org.springframework.boot:spring-boot-starter-web")

entity :

@Document(collection="customer")
 public class Customer {
 
 @Id
 private String id;
 
 private String firstName;
 private String lastName;

repository :

public interface CustomerRepository extends MongoRepository<Customer, String>,QueryDslPredicateExecutor<Customer> {
 }

controller :

//http://localhost:8080/id
 @RequestMapping("/{id}")
 public Object getmongodbID(@PathVariable String id){
 return customerRepository.getIdCustomer(id);
 }

Then the contents obtained from the visit are from the test library. what’s going on?
