1.下载Qdrant
在虚拟机上利用Docker下载
链接:docker.io/langgenius/qdrant:v1.7.3 - 镜像下载 | docker.io (aityp.com)
- docker pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/langgenius/qdrant:v1.7.3
- docker tag swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/langgenius/qdrant:v1.7.3 docker.io/langgenius/qdrant:v1.7.3
复制代码 2.运行Qdrant
- docker run -p 6333:6333 -p 6334:6334 swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/langgenius/qdrant:v1.7.3
复制代码 3.添加Maven依靠
- <dependency>
- <groupId>io.qdrant</groupId>
- <artifactId>client</artifactId>
- <version>1.10.0</version>
- </dependency>
复制代码 4.Java操作Qdrant
官方文档:Local Quickstart - Qdrant
- // 创建客户端链接
- QdrantClient client = new QdrantClient(
- QdrantGrpcClient.newBuilder("192.168.40.130", 6334, false).build());
- // 创建collection
- client.createCollectionAsync("my_collection",
- Collections.VectorParams.newBuilder()
- .setDistance(Collections.Distance.Cosine)
- .setSize(4)
- .build()).get();
- // 插入向量
- HashMap<String, JsonWithInt.Value> map1 = new HashMap<>();
- map1.put("color", value("red"));
- map1.put("rand_number", value(32));
- HashMap<String, JsonWithInt.Value> map2 = new HashMap<>();
- map2.put("color", value("blue"));
- map2.put("rand_number", value(53));
- map2.put("extra_field", value(true));
- List<Points.PointStruct> points = new ArrayList<>();
- points.add(Points.PointStruct.newBuilder()
- .setId(id(1))
- .setVectors(vectors(0.32f, 0.52f, 0.21f, 0.52f))
- .putAllPayload(map1)
- .build());
- points.add(Points.PointStruct.newBuilder()
- .setId(id(2))
- .setVectors(vectors(0.42f, 0.52f, 0.67f, 0.632f))
- .putAllPayload(map2)
- .build());
- Points.UpdateResult updateResult = client.upsertAsync("my_collection", points).get();
- // 搜索相似结果
- List<Points.ScoredPoint> points1 = client.searchAsync(
- Points.SearchPoints.newBuilder()
- .setCollectionName("my_collection")
- .addAllVector(Arrays.asList(0.6235f, 0.123f, 0.532f, 0.123f))
- .setLimit(5)
- .build()).get();
- System.out.println(points1);
- // 搜索相似结果带过滤条件
- List<Points.ScoredPoint> points2 = client.searchAsync(
- Points.SearchPoints.newBuilder()
- .setCollectionName("my_collection")
- .addAllVector(Arrays.asList(0.6235f, 0.123f, 0.532f, 0.123f))
- .setFilter(Points.Filter.newBuilder()
- .addMust(range("rand_number", Points.Range.newBuilder().setGte(3).build()))
- .build())
- .setLimit(5)
- .build()).get();
- System.out.println(points2);
