基础工具

1. spring boot
2. maven
3. mongoDB

目标

1. 了解 mongodb 的查询语句
2. 了解 spring boot 及 mongodb 的配置并使用

搭建的目的

移动端记录了用户对 APP 的操作行为并会上报至服务端且会持久化，需要对这些信息作校验，
所以搭建这个服务用来查询数据库，在使用 UI 测试工具在 APP 端测试时，并检查服务端是否有对应的行为记录

prop 配置

spring.data.mongodb.database=countly
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017

logging.level.org.springframework.data.mongodb.core.MongoTemplate=DEBUG

配置数据源并开启 mongo 日志，方便查看实际执行的查询语句

bean

@Data
@Document(collection = "logs5729aa86ff5812096852d481")
public class EventMongo {

    @Id
    private String id;
    private String ts;
    private String reqts;
    private String d;
    private String l;
    private String v;
    private String t;
    private String i;
    private String s;
    private String c;

    public EventMongo() {

    }

}

这里 collection 是 mongoDB 的表名

接口配置

public interface EventMapperMongo extends MongoRepository<EventMongo, String> {

    /**
     * 通过DeviceId查找到对应的事件
     * @param deviceId
     * @param startTime
     * @param endTime
     * @return
     */
    @Query("{'d.id':?#{[0]}, 't':'event', 'i.timestamp':{$gt:?#{[1]}, $lt:?#{[2]}}}")
    public List<EventMongo> findAllByQuery(String deviceId, long startTime, long endTime);
}

和 mysql 不一样，不是使用 Select，而是 Query，然后取值，“?#{[0]}” 这个表示取第一个参数，这里是 deviceId

具体实现

@RestController
@RequestMapping("/mongoEvent")
@Slf4j
public class EventControllerMongo {

    @Autowired
    private EventMapperMongo eventMapperMongo;

    @RequestMapping(method = RequestMethod.GET, value = "/deviceId/{deviceId}/startTime/{startTime}/endTime/{endTime}")
    public List<EventMongo> getEvents(@PathVariable("deviceId") String deviceId, @PathVariable("startTime") long startTime, @PathVariable("endTime") long endTime) {
        return eventMapperMongo.findAllByQuery(deviceId, startTime, endTime);
    }

}

log 输出

2017-11-21 22:54:06.378 DEBUG 41848 --- [nio-9980-exec-1] o.s.data.mongodb.core.MongoTemplate      : find using query: { "d.id" : "c7bed21e-f1fa-4241-9b80-85943f6dcd33" , "t" : "event" , "i.timestamp" : { "$gt" : 1511253238 , "$lt" : 1511253318}} fields: null for class: class com.jolly.mobiletestservice.beans.EventMongo in collection: logs5729aa86ff5812096852d481

mongo 查询语句

db.getCollection('logs5729aa86ff5812096852d481').find({ "d.id" : "c7bed21e-f1fa-4241-9b80-85943f6dcd33" , "t" : "event" , "i.timestamp" : { "$gt" : 1511249952 , "$lt" : 1511259269}})

我的猜测

因为记录了用户的行为，所以它也是日后用户行为分析的基础，但具体怎么玩，还不清楚
