# 在 Amazon Pinpoint 中创建分段
<a name="examples-pinpoint-create-segment"></a>

用户分段表示基于共同的特征（例如用户最近什么时候打开了您的应用程序或他们使用哪个设备）的用户子集。以下示例演示如何定义用户分段。

## 创建分段
<a name="create-a-segment"></a>

通过在 Amazon PinpointSegmentDimensions[ 对象中创建分段的维度，在 ](https://docs.amazonaws.cn/sdk-for-java/v1/reference/com/amazonaws/services/pinpoint/model/SegmentDimensions.html) 中创建新的分段。

 **导入**。

```
import com.amazonaws.services.pinpoint.AmazonPinpoint;
import com.amazonaws.services.pinpoint.AmazonPinpointClientBuilder;
import com.amazonaws.services.pinpoint.model.CreateSegmentRequest;
import com.amazonaws.services.pinpoint.model.CreateSegmentResult;
import com.amazonaws.services.pinpoint.model.AttributeDimension;
import com.amazonaws.services.pinpoint.model.AttributeType;
import com.amazonaws.services.pinpoint.model.RecencyDimension;
import com.amazonaws.services.pinpoint.model.SegmentBehaviors;
import com.amazonaws.services.pinpoint.model.SegmentDemographics;
import com.amazonaws.services.pinpoint.model.SegmentDimensions;
import com.amazonaws.services.pinpoint.model.SegmentLocation;
import com.amazonaws.services.pinpoint.model.SegmentResponse;
import com.amazonaws.services.pinpoint.model.WriteSegmentRequest;
```

 **代码** 

```
Pinpoint pinpoint = AmazonPinpointClientBuilder.standard().withRegion(Regions.US_EAST_1).build();
Map<String, AttributeDimension> segmentAttributes = new HashMap<>();
segmentAttributes.put("Team", new AttributeDimension().withAttributeType(AttributeType.INCLUSIVE).withValues("Lakers"));

SegmentBehaviors segmentBehaviors = new SegmentBehaviors();
SegmentDemographics segmentDemographics = new SegmentDemographics();
SegmentLocation segmentLocation = new SegmentLocation();

RecencyDimension recencyDimension = new RecencyDimension();
recencyDimension.withDuration("DAY_30").withRecencyType("ACTIVE");
segmentBehaviors.setRecency(recencyDimension);

SegmentDimensions dimensions = new SegmentDimensions()
        .withAttributes(segmentAttributes)
        .withBehavior(segmentBehaviors)
        .withDemographic(segmentDemographics)
        .withLocation(segmentLocation);
```

接下来，在 [WriteSegmentRequest](https://docs.amazonaws.cn/sdk-for-java/v1/reference/com/amazonaws/services/pinpoint/model/SegmentDimensions.html) 中设置 [SegmentDimensions](https://docs.amazonaws.cn/sdk-for-java/v1/reference/com/amazonaws/services/pinpoint/model/WriteSegmentRequest.html) 对象，接着使用该对象创建 [CreateSegmentRequest](https://docs.amazonaws.cn/sdk-for-java/v1/reference/com/amazonaws/services/pinpoint/model/CreateSegmentRequest.html) 对象。然后，将 CreateSegmentRequest 对象传递到 AmazonPinpointClient 的 `createSegment` 方法。

 **代码** 

```
WriteSegmentRequest writeSegmentRequest = new WriteSegmentRequest()
        .withName("MySegment").withDimensions(dimensions);

CreateSegmentRequest createSegmentRequest = new CreateSegmentRequest()
        .withApplicationId(appId).withWriteSegmentRequest(writeSegmentRequest);

CreateSegmentResult createSegmentResult = client.createSegment(createSegmentRequest);
```
