简介： 本文介绍了如何在Spring Boot中操作NoSQL数据库MongoDB，包括在MongoDB官网创建服务器、配置Spring Boot项目、创建实体类、仓库类、服务类和控制器类，以及如何进行测试。

第一步：在mongodb的官网里面创建云服务器

点进去

这是免费的，由于是一个项目只可以创建一个，这里我已经创建好了

用本地的mongodb服务也是可以的

第二步：点击connect,下载连接mongodb的软件：MongoDBCompass

第三步：创建springboot项目

3.2 配置文件：

spring.data.mongodb.database=${env.MONGO_DATABASE}
spring.data.mongodb.uri=mongodb+srv://${env.MONGO_USER}:${env.MONGO_PASSWORD}@${env.MONGO_CLUSTER}

.env文件：

MONGO_DATABASE=这个是你的那个数据库
MONGO_USER=账号
MONGO_PASSWORD=密码
MONGO_CLUSTER=服务器的节点

这些信息都是可以在服务器那边连接的时候看到

创建实体类：

复制粘贴到一个json文件里面，然后导入：

创建MovieRepository类：

package dev.farhan.movies.repository;

import dev.farhan.movies.pojo.Movie;
import org.bson.types.ObjectId;
import org.springframework.data.mongodb.repository.MongoRepository;
import org.springframework.stereotype.Repository;

import java.util.Optional;

@Repository
public interface MovieRepository extends MongoRepository<Movie, ObjectId> {
    Optional<Movie> findMovieByImdbId(String imdbId);
}

创建MovieService类：

package dev.farhan.movies.service;

import dev.farhan.movies.repository.MovieRepository;
import dev.farhan.movies.pojo.Movie;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Optional;

@Service
public class MovieService {

    @Autowired
    private MovieRepository repository;

    public List<Movie> findAllMovies() {
        return repository.findAll();
    }
    public Optional<Movie> findMovieByImdbId(String imdbId) {
        return repository.findMovieByImdbId(imdbId);
    }
}

创建controller类，进行测试：

package dev.farhan.movies.controller;

import dev.farhan.movies.pojo.Movie;
import dev.farhan.movies.service.MovieService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;

import java.util.List;
import java.util.Optional;

@RestController
@RequestMapping("/api/v1/movies")
public class MovieController {

    @Autowired
    private MovieService service;

    @GetMapping
    public ResponseEntity<List<Movie>> getMovies() {
        return new ResponseEntity<List<Movie>>(service.findAllMovies(), HttpStatus.OK);
    }

    @GetMapping("/{imdbId}")
    public ResponseEntity<Optional<Movie>> getSingleMovie(@PathVariable String imdbId){
        return new ResponseEntity<Optional<Movie>>(service.findMovieByImdbId(imdbId), HttpStatus.OK);
    }
}

启动，并访问：localhost:8080/api/v1/movies

结果：成功

GraphRAG：基于PolarDB+通义千问+LangChain的知识图谱+大模型最佳实践
本文介绍了如何使用PolarDB、通义千问和LangChain搭建GraphRAG系统，结合知识图谱和向量检索提升问答质量。通过实例展示了单独使用向量检索和图检索的局限性，并通过图+向量联合搜索增强了问答准确性。PolarDB支持AGE图引擎和pgvector插件，实现图数据和向量数据的统一存储与检索，提升了RAG系统的性能和效果。

人工智能 开发框架 Java
重磅发布！AI 驱动的 Java 开发框架：Spring AI Alibaba
随着生成式 AI 的快速发展，基于 AI 开发框架构建 AI 应用的诉求迅速增长，涌现出了包括 LangChain、LlamaIndex 等开发框架，但大部分框架只提供了 Python 语言的实现。但这些开发框架对于国内习惯了 Spring 开发范式的 Java 开发者而言，并非十分友好和丝滑。因此，我们基于 Spring AI 发布并快速演进 Spring AI Alibaba，通过提供一种方便的 API 抽象，帮助 Java 开发者简化 AI 应用的开发。同时，提供了完整的开源配套，包括可观测、网关、消息队列、配置中心等。
