Java org.springframework.beans.factory.unsatifiedDependencyException:创建名为'；solrDocumentController'；

我将按照以下步骤创建一个spring应用程序

这是我的主课

package com.example.webtool;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.solr.repository.config.EnableSolrRepositories;


@SpringBootApplication
@EnableSolrRepositories(
        basePackages = "com.example.webtool.repository"
)
public class WebtoolApplication {

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

}

这是我的存储库类

package com.example.webtool.repository;

import java.util.List;
import org.springframework.data.solr.repository.SolrCrudRepository;
import com.example.webtool.model.Document;
import org.springframework.stereotype.Service;

public interface DocumentRepository extends SolrCrudRepository<Document, String> {
    List<Document> findAllByPerson(String person); // find documents whose person name matches the name of the person in the query
    List<Document> findAllByRank(String rank); // find documents whose rank matches the rank of the person in the query

}

这是我的控制器类

package com.example.webtool.controller;

import com.example.webtool.model.Document;
import com.example.webtool.repository.DocumentRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

/**
 * Created by Siddharth Sinha
 */

@RestController
public class SolrDocumentController {

    @Autowired
    private DocumentRepository documentRepository;

    @RequestMapping("/")
    public String SampleController() {
        return "THis is a sample page!!!!";
    }

    @PostMapping("/search")
    public List<Document> getDocs(@RequestBody String name) {
        return this.documentRepository.findAllByPerson(name);
    }
}

我的应用程序有什么问题？

错误日志告诉您：

未找到com.example.webtool.model.Document类所需的标识符属性

@Id
@索引（name=“id”，type=“string”）
私有字符串id；
