here is my controller :

import com.movie.db.KotakKantorMovieDB.repository.CustomerRepository;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
public class CustomerController {

  @Autowired
  private CustomerRepository repository;

  @GetMapping("/customer")
  public Customer findCustomer() {
    return repository.findByFirstName("cactuspot");
  }

  @PostMapping("/addcustomer")
  public Customer addCustomer(@RequestBody Customer newCustomer ) {
    return repository.save(newCustomer);
  }

}

here is my model :

package com.movie.db.KotakKantorMovieDB.models;

import org.springframework.data.annotation.Id;

public class Customer {
    @Id
    public String id;

    public String firstName;
    public String lastName;

    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;
    }

}

and here is my repository :

package com.movie.db.KotakKantorMovieDB.repository;

import java.util.List;

import com.movie.db.KotakKantorMovieDB.models.Customer;

import org.springframework.data.mongodb.repository.MongoRepository;

public interface CustomerRepository extends MongoRepository<Customer, String> {

    public Customer findByFirstName(String firstName);
    public List<Customer> findByLastName(String lastName);

}

what did i missed here? i is there some dependency that i shouldn't use whtn i add spring-boot-starter-data-rest?

See stackoverflow.com/questions/17726282/… – user7294900
i already add json-path dependency in my pom.xml, u can see it in my pom.xml before – Ke Vin
The dependency is on test scope. It means it's only available during test compilation/execution. Remove the scope tag to use "compile" scope – dgzz
@danieljohngomez tried it, and it doesn't fixed the error, still have the same error – Ke Vin

i trying to delete :

<dependency>
            <groupId>com.jayway.jsonpath</groupId>
            <artifactId>json-path</artifactId>
            <scope>test</scope>
</dependency>

this dependency, and it solved the error, i dunno why this dependency cause the error, and i dunno why this dependency is needed, i run my apps and it just work fine without this dependency. maybe there is something to do with HATEOAS. If somebody can explain it to me, i will accept it as an answer

I came from udemy. I got the same error and the author suggested to replace

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-browser</artifactId>
<version>3.3.6.RELEASE</version>
</dependency>

with

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-explorer</artifactId>
</dependency>

It works in my case.
