SpringBoot整合MongoDB
SpringBoot整合MongoDB
背景
- 大数据领域的MongoDB在实际开发中有很多应用，基于文档的存储结构和关系型数据库有很大的区别，下面来通过SpringBoot整合MongoDB来理解一下这个数据库
- 注：MongoDB中数据表叫集合Collection，一条记录叫文档Document
- 以下为SpringBoot项目配置
SpringBoot整合MongoDB
POM
-
4.0.0 org.springframework.boot spring-boot-starter-parent 2.7.2 com.example mongodb 0.0.1-SNAPSHOT mongodb mongodb 1.8 org.springframework.boot spring-boot-starter-data-mongodb org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-devtools runtime true org.projectlombok lombok true org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin org.projectlombok lombok
YML
-
spring: data: mongodb: host: 192.168.0.1 port: 27017 username: root password: root database: test authenticationDatabase: test #spring: # data: # mongodb: # uri: mongodb://192.168.61.4:27017/test server: port: 80
MongoDB实体类
-
@Document(“t_his_curve_highway”) 表示这条记录Document插入MongoDB中的t_his_curve_highway的Collection中
-
@Indexed 表示该字段为索引
-
@Field(“highway_id”) 表示该字段对应到MongoDB中的Collection中字段名为highway_id
-
import com.baomidou.mybatisplus.annotation.TableField; import lombok.*; import org.springframework.data.annotation.Transient; import org.springframework.data.mongodb.core.index.Indexed; import org.springframework.data.mongodb.core.mapping.Document; import org.springframework.data.mongodb.core.mapping.Field; import java.io.Serializable; @Data @Builder(toBuilder = true) @NoArgsConstructor @AllArgsConstructor @EqualsAndHashCode(callSuper = false) @Document("t_his_curve_highway") public class StaCharHisCurveHighwayDto implements Serializable { /** * highwayId */ @Indexed @Field("highway_id") private String highwayId; /** * recDate */ @Field("rec_date") private String recDate; /** * curveCode */ @Field("curve_code") private String curveCode; /** * curveData */ @Field("curve_data") private String curveData; /** * recId */ @TableField("recId") private String recId; /** * day */ @Transient private Integer day; }
MongoDB接口
-
import com.xxx.job.dto.HighwayDto; import java.util.List; public interface MongoDBRepository { void saveHighwayData(ListhighwayDtoList); }
MongoDB接口实现类
-
使用MongoTemplate实现MongoDB批量插入数据功能
-
import com.xxx.job.dto.HighwayDto; import lombok.extern.slf4j.Slf4j; import org.bson.Document; import org.springframework.data.mongodb.core.BulkOperations; 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.data.util.Pair; import org.springframework.stereotype.Component; import javax.annotation.Resource; import java.util.ArrayList; import java.util.List; @Component @Slf4j public class MongoDBRepositoryImpl implements MongoDBRepository { //注入MongoTemplate @Resource private MongoTemplate mongoTemplate; /** * 添加数据 * * @param staCharHisCurveHighwayDtoList */ @Override public void saveStaCharHisCurveHighwayData(ListhighwayDtoList) { log.info("Highway正在写入mongodb数据库，数量 {} ", highwayDtoList.size()); List
效果
- MongoDB数据库表Collection

MongoTemplate增删改查测试用例
实体
-
package com.example.mongodb.entity; import lombok.Data; import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document; import org.springframework.data.mongodb.core.mapping.Field; import java.io.Serializable; @Data @Document("User") public class User implements Serializable { @Id private String id; private String name; private Integer age; private String email; @Field("create_date") private String createDate; }
测试用例
-
在SpringBoot中Test文件夹下编写测试用例使用Mongo Template实现数据的增删改查
-
package com.example.mongodb.test; import com.example.mongodb.entity.User; import com.mongodb.client.result.DeleteResult; import com.mongodb.client.result.UpdateResult; import org.junit.jupiter.api.Test; import org.springframework.boot.test.context.SpringBootTest; 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 javax.annotation.Resource; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.regex.Pattern; @SpringBootTest class MongoTemplateTest { @Resource private MongoTemplate mongoTemplate; //添加 @Test public void createUser() { User user = new User(); user.setAge(23); user.setName("test2"); user.setEmail("[email protected]"); user.setCreateDate(String.valueOf(new Date())); User user1 = mongoTemplate.insert(user); System.out.println(user1); } //查询所有 @Test public void findUser() { ListuserList = mongoTemplate.findAll(User.class); System.out.println(userList); } //根据id查询 @Test public void getById() { User user = mongoTemplate.findById("60534ac7548d761b193cf2d7", User.class); System.out.println(user); } //条件查询 @Test public void findUserList() { Query query = new Query(Criteria .where("name").is("test") .and("age").is(20)); List userList = mongoTemplate.find(query, User.class); System.out.println(userList); } //模糊查询 @Test public void findUsersLikeName() { String name = "est"; String regex = String.format("%s%s%s", "^.*", name, ".*$"); Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); Query query = new Query(Criteria.where("name").regex(pattern)); List userList = mongoTemplate.find(query, User.class); System.out.println(userList); } //分页查询 @Test public void findUsersPage() { String name = "est"; int pageNo = 1; int pageSize = 10; Query query = new Query(); String regex = String.format("%s%s%s", "^.*", name, ".*$"); Pattern pattern = Pattern.compile(regex, Pattern.CASE_INSENSITIVE); query.addCriteria(Criteria.where("name").regex(pattern)); int totalCount = (int) mongoTemplate.count(query, User.class); List userList = mongoTemplate.find(query.skip((pageNo - 1) * pageSize).limit(pageSize), User.class); Map
