如何使用java KMS API设置密钥环的保护级别？

import com.tencentcloudapi.kms.v20190118.KmsClient;
import com.tencentcloudapi.kms.v20190118.models.SetKeyProtectionLevelRequest;
import com.tencentcloudapi.kms.v20190118.models.SetKeyProtectionLevelResponse;

public class KMSExample {
    public static void main(String[] args) {
        try {
            // 创建KMSClient对象
            KmsClient client = new KmsClient();

            // 设置密钥环的保护级别
            SetKeyProtectionLevelRequest request = new SetKeyProtectionLevelRequest();
            request.setKeyId("your-key-id");  // 密钥环的ID
            request.setProtectionLevel("HSM");  // 目标保护级别

            SetKeyProtectionLevelResponse response = client.SetKeyProtectionLevel(request);

            // 处理响应结果
            System.out.println("设置密钥环保护级别成功");
        } catch (Exception e) {
            // 处理异常情况
            System.err.println("设置密钥环保护级别失败：" + e.getMessage());
        }
    }
}
