MongoDB的学习-安装与springboot的整合

mongoDB的学习：

1.mongodb 安装及使用

配置环境变量，使在任意位置都可以执行bin下的exe程序

配置完成后，这样就成功了。

2.开始整合springboot+mongoDB

1.导入依赖

<!--  mongodb依赖      --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-mongodb</artifactId></dependency>

2.添加mongodb配置yaml配置

  #mongodb配置spring:data:mongodb:host: localhostport: 27017#      mongodb数据库名称database: monge_demo

3.新增实体类对应mongodb的集合进行关系映射

package com.ljquan.test.pojo.mongoDB;import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;import java.util.Date;/*** @className Article* @Description 文章  用于mongodb的测试* @Author ljquan* @Date 2022-06-10 11:39:02* @Version 1.0.0*/
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class Article {/*** 文章id*/@Idprivate Long id;/*** 用户ID*/private Long userId;/*** 文章标题*/private String title;/*** 文章内容*/private String content;/*** 创建时间*/private Date createTime;/*** 更新时间*/private Date updateTime;/*** 点赞数量*/private Long thumbUp;/*** 访客数量*/private Long visits;}

4.开始使用Mongodb和springboot整合

创建ArticleService接口

package com.ljquan.test.service.mongoDB;import com.ljquan.test.pojo.mongoDB.Article;
import org.springframework.stereotype.Service;import java.util.List;/*** @className ArticleService* @Description 服务条* @Author ljquan* @Date 2022-06-10 13:54:33* @Version 1.0.0*/
@Service
public interface ArticleService {/*** 插入文章* 插入** @param article 文章* @return int*/int insertArticle(Article article);/*** 更新文章** @param article 文章* @return int*/int updateArticle(Article article);/*** 删除文章** @param id id* @return int*/int removeArticle(Long id);/*** 找到所有** @param article 文章* @return {@code List<Article>}*/List<Article> findAll(Article article);/*** 找到一个** @param article 文章* @return {@code Article}*/Article findOne(Article article);/*** 找到喜欢** @param article 文章* @return {@code List<Article>}*/List<Article> findLike(Article article);/*** 找到更多** @param article 文章* @return {@code List<Article>}*/List<Article> findMore(Article article);}

创建实现类ArticleServiceImpl

package com.ljquan.test.service.mongoDB.impl;import cn.hutool.core.date.DateUtil;
import com.ljquan.test.pojo.mongoDB.Article;
import com.ljquan.test.service.mongoDB.ArticleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;
import org.springframework.stereotype.Service;import java.time.LocalDateTime;
import java.util.List;
import java.util.regex.Pattern;@Service
public class ArticleServiceImpl implements ArticleService {@AutowiredMongoTemplate mongoTemplate;/*** 插入文章** @param article 文章* @return int*/@Overridepublic int insertArticle(Article article) {try {article.setCreateTime(DateUtil.date());mongoTemplate.insert(article);return 1;} catch (Exception e) {e.printStackTrace();return -1;}}/*** 更新文章** @param article 文章* @return int*/@Overridepublic int updateArticle(Article article) {//通过query根据id查询出对应对象，通过update对象进行修改Query query = new Query(Criteria.where("_id").is(article.getId()));//更改信息Update update = new Update().set("username", article.getTitle());try {mongoTemplate.updateFirst(query, update, Article.class);return 1;} catch (Exception e) {e.printStackTrace();return -1;}}/*** 删除文章** @param id id* @return int*/@Overridepublic int removeArticle(Long id) {Query query = new Query(Criteria.where("_id").is(id));try {mongoTemplate.remove(query, Article.class);return 1;} catch (Exception e) {e.printStackTrace();return -1;}}/*** 找到所有** @param article 文章* @return {@code List<Article>}*/@Overridepublic List<Article> findAll(Article article) {Query query = new Query(Criteria.where("_id").is(article.getId()));return mongoTemplate.findAll(Article.class, article.getTitle());}@Overridepublic Article findOne(Article article) {Query query = new Query(Criteria.where("_id").is(article.getId()));return mongoTemplate.findOne(query, Article.class);}/*** 模糊查询** @param article 文章* @return {@code List<Article>}*/@Overridepublic List<Article> findLike(Article article) {//设置Pattern pattern = Pattern.compile("^.*" + article.getContent().trim() + ".*$", Pattern.CASE_INSENSITIVE);Query query = new Query(Criteria.where("content").regex(pattern));return mongoTemplate.find(query, Article.class);}/*** 找到更多** @param article 文章* @return {@code List<Article>}*/@Overridepublic List<Article> findMore(Article article) {Query query = new Query(Criteria.where("content").is(article.getContent()));return mongoTemplate.find(query, Article.class);}}

这里是最重要的，调用了刚刚导入进来的依赖，然后调用里面的接口实现整合

@Autowired
MongoTemplate mongoTemplate;

5.测试

   @AutowiredArticleServiceImpl articleService;/*** 测试发现相似*/@Testpublic void testFindLike() {Article build = Article.builder().content("7").build();List<Article> like = articleService.findLike(build);System.out.println(like.size());like.forEach(article -> {System.out.println(article.getContent());});}/*** 测试插入文章*/@Testpublic void testInsertArticle() {Article build = Article.builder().content("7").id(snowflake.nextId()).createTime(DateUtil.date()).thumbUp(9L).updateTime(DateUtil.date()).build();int i = articleService.insertArticle(build);log.info("【article】= {} 插入成功", JSONUtil.toJsonStr(build));}/*** 测试发现所有*/@Testpublic void testFindAll() {List<Article> all = articleService.findAll();log.info(all + " ");}……
