如何使用spring从mongoDB获取集合中的所有文档

// 配置MongoDB连接
@Configuration
public class MongoConfig {

    @Bean
    public MongoClient mongoClient() {
        return MongoClients.create("mongodb://localhost:27017");
    }

    @Bean
    public MongoTemplate mongoTemplate() {
        return new MongoTemplate(mongoClient(), "your_database_name");
    }
}

// 创建MongoDB数据模型
@Document(collection = "your_collection_name")
public class YourDocument {

    @Id
    private String id;

    private String name;

    // getters and setters
}

// 创建MongoDB数据访问接口
public interface YourDocumentRepository extends MongoRepository<YourDocument, String> {

    List<YourDocument> findAll();
}

// 实现MongoDB数据访问接口
@Repository
public class YourDocumentRepositoryImpl implements YourDocumentRepository {

    @Autowired
    private MongoTemplate mongoTemplate;

    @Override
    public List<YourDocument> findAll() {
        return mongoTemplate.findAll(YourDocument.class);
    }

    // other methods
}

// 在需要使用MongoDB数据的地方注入MongoDB数据访问接口
@Service
public class YourService {

    @Autowired
    private YourDocumentRepository yourDocumentRepository;

    public List<YourDocument> getAllDocuments() {
        return yourDocumentRepository.findAll();
    }

    // other methods
}
