# `GetFoundationModel` 搭配 AWS SDK 使用
下列程式碼範例示範如何使用 `GetFoundationModel`。
------
#### [ Java ]
**SDK for Java 2.x**
GitHub 上提供更多範例。尋找完整範例，並了解如何在 [AWS 程式碼範例儲存庫](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/javav2/example_code/bedrock#code-examples)中設定和執行。
使用同步 Amazon Bedrock 用戶端，取得基礎模型的詳細資訊。
```
/**
* Get details about an Amazon Bedrock foundation model.
*
* @param bedrockClient The service client for accessing Amazon Bedrock.
* @param modelIdentifier The model identifier.
* @return An object containing the foundation model's details.
*/
public static FoundationModelDetails getFoundationModel(BedrockClient bedrockClient, String modelIdentifier) {
try {
GetFoundationModelResponse response = bedrockClient.getFoundationModel(
r -> r.modelIdentifier(modelIdentifier)
);
FoundationModelDetails model = response.modelDetails();
System.out.println(" Model ID: " + model.modelId());
System.out.println(" Model ARN: " + model.modelArn());
System.out.println(" Model Name: " + model.modelName());
System.out.println(" Provider Name: " + model.providerName());
System.out.println(" Lifecycle status: " + model.modelLifecycle().statusAsString());
System.out.println(" Input modalities: " + model.inputModalities());
System.out.println(" Output modalities: " + model.outputModalities());
System.out.println(" Supported customizations: " + model.customizationsSupported());
System.out.println(" Supported inference types: " + model.inferenceTypesSupported());
System.out.println(" Response streaming supported: " + model.responseStreamingSupported());
return model;
} catch (ValidationException e) {
throw new IllegalArgumentException(e.getMessage());
} catch (SdkException e) {
System.err.println(e.getMessage());
throw new RuntimeException(e);
}
}
```
使用非同步 Amazon Bedrock 用戶端，取得基礎模型的詳細資訊。
```
/**
* Get details about an Amazon Bedrock foundation model.
*
* @param bedrockClient The async service client for accessing Amazon Bedrock.
* @param modelIdentifier The model identifier.
* @return An object containing the foundation model's details.
*/
public static FoundationModelDetails getFoundationModel(BedrockAsyncClient bedrockClient, String modelIdentifier) {
try {
CompletableFuture future = bedrockClient.getFoundationModel(
r -> r.modelIdentifier(modelIdentifier)
);
FoundationModelDetails model = future.get().modelDetails();
System.out.println(" Model ID: " + model.modelId());
System.out.println(" Model ARN: " + model.modelArn());
System.out.println(" Model Name: " + model.modelName());
System.out.println(" Provider Name: " + model.providerName());
System.out.println(" Lifecycle status: " + model.modelLifecycle().statusAsString());
System.out.println(" Input modalities: " + model.inputModalities());
System.out.println(" Output modalities: " + model.outputModalities());
System.out.println(" Supported customizations: " + model.customizationsSupported());
System.out.println(" Supported inference types: " + model.inferenceTypesSupported());
System.out.println(" Response streaming supported: " + model.responseStreamingSupported());
return model;
} catch (ExecutionException e) {
if (e.getMessage().contains("ValidationException")) {
throw new IllegalArgumentException(e.getMessage());
} else {
System.err.println(e.getMessage());
throw new RuntimeException(e);
}
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
System.err.println(e.getMessage());
throw new RuntimeException(e);
}
}
