cd find-nearest-vehicle
./mvnw spring-boot:run
```
## Redis Geohash - Adding Geospatial Data In Spring Boot
Redis offers the GEOADD command to add geospatial data. You can use it to add a single or multiple locations at once. Let's start with a single location.
## Using GeoOperations For Adding In Spring Boot
```java
private final GeoOperations geoOperations;
public static final String vehicleLocation = "vehicle_location";
public void add(VehicleLocationRequest request) {
Point point = new Point(request.getLongitude(), request.getLatitude());
geoOperations.add(vehicleLocation, point, request.getVehicleName());
}
```
## Redis Geohash - Fetching Geospatial Data In Spring Boot
Fetching geospatial data is performed with GEODIST, GEORADIUS, or GEORADIUSBYMEMBER. Let's focus on GEORADIUS, which allows us to query locations within a specific radius of a point.
## Using GeoOperations For Fetching In Spring Boot
```java
public List findNearestVehicles(Double longitude, Double latitude, int km) {
RedisGeoCommands.GeoRadiusCommandArgs args = RedisGeoCommands
.GeoRadiusCommandArgs.newGeoRadiusArgs().includeCoordinates()
.includeDistance().sortAscending().limit(10);
Circle circle = new Circle(new Point(longitude, latitude)
,new Distance(km, Metrics.KILOMETERS));
GeoResults> response =
geoOperations.radius(vehicleLocation, circle, args);
List vehicleLocationResponses = new ArrayList<>();
response.getContent().stream().forEach(data -> {
vehicleLocationResponses.add(VehicleLocationResponse.builder()
.vehicleName(data.getContent().getName())
.averageDistance(data.getDistance().toString())
.point(data.getContent().getPoint())
.hash(geoOperations.hash(vehicleLocation,data.getContent().getName()).stream().findFirst().get())
.build());
});
return vehicleLocationResponses;
}
```
