Getting data from the wrong database

Question

This is the process how I get data from database:

UserController.java

@RequestMapping("user")
public Optional<String> getUserService() {
    return userService.getUser();
}

UserService.java

@Service
public class UserService {
final UserRepository userRepository;

    public UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }
    
    public Optional<String> getUser() {
        return userRepository.findById(1).map(User::getName);
    }
}

UserRepository.java

@Repository
public interface UserRepository extends CrudRepository<User, Integer> {

}

User.java

@Entity(name = "users")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    private String name;
    
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

If I run my application, I get my result BUT from the wrong database! I am using 3 different databases. See application.properties:

#default
spring.default.datasource.url=jdbc:postgresql://localhost:5432/webshop-analyser?createDatabaseIfNotExists=true
spring.default.datasource.driver-class-name=org.postgresql.Driver
spring.default.datasource.username=postgres
spring.default.datasource.password=reza

spring.jpa.hibernate.ddl-auto=update
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
spring.jpa.properties.hibernate.show_sql=true

#Example 1
spring.wila.datasource.url=https://example.com
spring.wila.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.wila.datasource.username=test
spring.wila.datasource.password=test

#Example 2
spring.wald.datasource.url=https://example2.com
spring.wald.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.wald.datasource.username=
spring.wald.datasource.password=

So how can I get a result from the database of spring.wila.datasource.url instead of spring.default.datasource.url?
