MongoDB在SpringBoot中使用
作者：互联网
1.引用
<!-- mongo -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
2.配置
####################mongodb########################## spring.data.mongodb.uri=mongodb://127.0.0.1:27017/earth
earth是db名，在创建db时还需要创建至少一个collection（类似table）
3.方法调用
@Component
public class MongoComponent {
@Autowired
private MongoTemplate mongoTemplate;
/**
*
* @param brand
*/
public void save(BrandEntity brand) {
mongoTemplate.save(brand);
}
/**
*
* @param registerNum
* @return
*/
public BrandEntity findByRegisterNum(String registerNum) {
Query q = new Query(Criteria.where("registerNum").is(registerNum));
return mongoTemplate.findOne(q, BrandEntity.class);
}
/**
*
* @param registerNum
*/
public void deleteByRegisterNum(String registerNum) {
Query q = new Query(Criteria.where("registerNum").is(registerNum));
mongoTemplate.remove(q, BrandEntity.class);
}
/**************************Collection************************/
/**
*
* @param brand
* @param collectionName
*/
public void saveInCollection(BrandEntity brand, String collectionName) {
mongoTemplate.save(brand, collectionName);
}
/**
*
* @param registerNum
*/
public void deleteByRegisterNumInCollection(String registerNum, String collectionName) {
Query q = new Query(Criteria.where("registerNum").is(registerNum));
mongoTemplate.remove(q, BrandEntity.class, collectionName);
}
/**
*
* @param registerNum
* @param collectionName
* @return
*/
public BrandEntity findOneByRegisterNumInCollection(String registerNum, String collectionName) {
Query q = new Query(Criteria.where("registerNum").is(registerNum));
return mongoTemplate.findOne(q, BrandEntity.class, collectionName);
}
/**
*
* @param sTime
* @param eTime
* @param collectionName
* @return
*/
public List<BrandEntity> findByIntervalInCollection(Date sTime, Date eTime, String collectionName) {
Query q = new Query(Criteria.where("updateTime").gte(sTime).lte(eTime));
return mongoTemplate.find(q, BrandEntity.class, collectionName);
}
}
