本文将介绍在SpringBoot中使用MongoDB的流程
引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
<optional>true</optional>
</dependency>
配置
application.yml
spring:
data:
mongodb:
host: 192.168.52.128 # mongodb 地址
database: covid # 数据库名
Pojo配置
@Document(collection = "crawler_record")
public class CrawlerRecord implements Serializable {
@Id
private String _id;
private String content;
private Date updateTime;
public String get_id() {
return _id;
}
public void set_id(String _id) {
this._id = _id;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
public Date getUpdateTime() {
return updateTime;
}
public void setUpdateTime(Date updateTime) {
this.updateTime = updateTime;
}
}
数据层
public interface CrawlerRecordRepository extends MongoRepository<CrawlerRecord, String> {
}
调用
此时就可以在service中注入服务调用
@Autowired
private CrawlerRecordRepository crawlerRecordRepository;
public void test(){
CrawlerRecord crawlerRecord = new CrawlerRecord();
crawlerRecord.setContent(result);
crawlerRecord.setUpdateTime(DateUtil.parserYMDHMS(DateUtil.formatYMDHMS(new Date())));
crawlerRecordRepository.insert(crawlerRecord);
System.out.println(crawlerRecordRepository.findAll().size());
}
