SpringBoot | ElasticSearch |不支持的ID类型

Question

[我正在尝试创建一个应用程序，在其中我可以通过spring boot和java执行弹性搜索功能，但是我正面临java.lang.IllegalArgumentException：不支持的ID类型类elastic.model.Identifier

这是代码的外观

我有模型课

package elastic.model;

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName="customCustomer", type="elkcustomer")
public class Customer {

    @Id
    private Identifier identifier;
    private Order order;
    private String homeAddress;
    private String contact;
    //getters, setters, hashcode, equals, toString()

标识符为

package elastic.model;

import java.io.Serializable;

public class Identifier implements Serializable {

    private String id;
    private String firstName;
    private String lastName;
    //getters, setters, hashcode,equals, toString()

订购为

package elastic.model;

import java.io.Serializable;

public class Order implements Serializable {

    private int orderId;
    private String orderDescription;
    private float price;
    //getters, setters, hashcode, equals, toString

存储库为

package elastic.repository;

import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Repository;

import elastic.model.Customer;
import elastic.model.Identifier;

@Repository
public interface CustomerRepository extends ElasticsearchRepository<Customer, Identifier> {

}

和主要跑步者为

package elastic.service;

import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.elasticsearch.repository.config.EnableElasticsearchRepositories;

import elastic.model.Customer;
import elastic.model.Identifier;
import elastic.model.Order;
import elastic.repository.CustomerRepository;

@SpringBootApplication
@EnableElasticsearchRepositories(basePackages="elastic")
public class ElasticSearchApplication implements CommandLineRunner {

    @Autowired private CustomerRepository customerRepository;

    public static void main(String[] args) {
        SpringApplication.run(ElasticSearchApplication.class);
    }

    public void run(String... args) throws Exception {
        this.customerRepository.deleteAll();
        saveCustomers();
    }

    private void saveCustomers() {
        this.customerRepository.saveAll(generateCustomers());
    }

    private List<Customer> generateCustomers() {
        List<Customer> customers = new ArrayList<Customer>();

        Customer customer1 = new Customer();
        Identifier identifier1 = new Identifier();
        identifier1.setId("1001");
        identifier1.setFirstName("Rahul");
        identifier1.setLastName("Lao");
        customer1.setIdentifier(identifier1);
        Order order1 = new Order();
        order1.setOrderId(1);
        order1.setOrderDescription("Order 1");
        order1.setPrice(23.45f);
        customer1.setOrder(order1);
        customer1.setHomeAddress("Germany");
        customer1.setContact("9874563210");

        customers.add(customer1);

        return customers;
    }

}

我面对的例外是

我该如何解决这个问题，以便我可以将自定义类作为ID，而不仅仅是像String，long，int这样的原始数据类型作为id。

谢谢。

Answer 1

public interface CustomerRepository extends ElasticsearchRepository<Customer, Identifier> {

}

ElasticsearchRepository无法识别Identifier，请尝试String
