springboot操作nosql的mongodb，或者是如何在mongodb官网创建服务器并进行操作

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

3.1 、pom依赖：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.0.12-SNAPSHOT</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>dev.farhan</groupId><artifactId>movies</artifactId><version>0.0.1-SNAPSHOT</version><name>movies</name><description>a simple APIS relates to movies</description><properties><java.version>17</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-mongodb</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><scope>runtime</scope><optional>true</optional></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- https://mvnrepository.com/artifact/me.paulschwarz/spring-dotenv --><dependency><groupId>me.paulschwarz</groupId><artifactId>spring-dotenv</artifactId><version>2.5.4</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><excludes><exclude><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></exclude></excludes></configuration></plugin></plugins></build><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url><snapshots><enabled>false</enabled></snapshots></repository><repository><id>spring-snapshots</id><name>Spring Snapshots</name><url>https://repo.spring.io/snapshot</url><releases><enabled>false</enabled></releases></repository></repositories><pluginRepositories><pluginRepository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url><snapshots><enabled>false</enabled></snapshots></pluginRepository><pluginRepository><id>spring-snapshots</id><name>Spring Snapshots</name><url>https://repo.spring.io/snapshot</url><releases><enabled>false</enabled></releases></pluginRepository></pluginRepositories></project>

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 {@Autowiredprivate 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 {@Autowiredprivate MovieService service;@GetMappingpublic 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
