SSM整合Mongodb(已解决版本冲突问题)

前言

本实例使用在SSM框架
spring版本4.3.7.RELEASE

实现

pom.xml引入依赖

<dependency>
			<groupId>org.springframework.data</groupId>
			<artifactId>spring-data-mongodb</artifactId>
			<version>1.10.23.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-validator</artifactId>
			<version>5.2.4.Final</version>
		</dependency>

创建spring-mongodb.xml

	<!--  引入配置文件-->
	<import resource="classpath:spring-mongodb.xml"></import>
	<!--  扫描包-->
	<context:component-scan base-package="com.mongodb.*" />

创建映射bean

@Data
@Document(collection = "LocBean")
public class Loc implements Serializable {
    @Id
    private String dateTime;
    private String name;
    private String Longitude;
    private String Latitude;
    private String Addr;
}

创建dao

public interface LocDao {

    /**
     * 查询
     * @param name
     * @return
     */
    List<Loc> getByTime(String name);
}

创建实现

@Slf4j
@Component(value = "LocDao ")
public class LocDaoImpl implements LocDao {

    @Resource
    private MongoTemplate mongoTemplate;

    @Override
    public List<Loc> getByTime(String name) {
        try {
            Query query = new Query();
            query.addCriteria(Criteria.where("name").is(name));
            return mongoTemplate.find(query,Loc.class);
        }catch (Exception e1){
            log.info("[MongoDB-FIND] ERROR MSG={},Data=",e1.getMessage());
            return null;
        }
    }
}
