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); } }
