-``` - -**Note**: ```SSMProvider.getMultiple()``` does not support transformation and will return simple Strings. - -**Write your own Transformer** - -You can write your own transformer, by implementing the ```Transformer``` interface and the ```applyTransformation()``` method. -For example, if you wish to deserialize XML into an object: - -```java:title=XmlTransformer.java -public class XmlTransformer implements Transformer { - - private final XmlMapper mapper = new XmlMapper(); - - @Override - public T applyTransformation(String value, Class targetClass) throws TransformationException { - try { - return mapper.readValue(value, targetClass); - } catch (IOException e) { - throw new TransformationException(e);

// finally get the value -``` - -## Create your own provider -You can create your own custom parameter store provider by inheriting the ```BaseProvider``` class and implementing the -```String getValue(String key)``` method to retrieve data from your underlying store. - -All transformation and caching logic is handled by the get() methods in the base class. - -Here is an example implementation using S3 as a custom parameter store: - -```java:title=S3Provider.java -public class S3Provider extends BaseProvider { - - private final S3Client client; - private String bucket; - - S3Provider(CacheManager cacheManager) { - this(cacheManager, S3Client.create()); - } - - S3Provider(CacheManager cacheManager, S3Client client) { - super(cacheManager); - this.client = client; - } - - public S3Provider withBucket(String bucket) { - this.bucket = bucket; - return this; - } - - @Override - protected String getValue(String key) { - if (bucket == null) { - throw new IllegalStateException("A bucket must be specified, using withBucket() method"); - } - - GetObjectRequest request = GetObjectRequest.builder().bucket(bucket).key(key).build(); - ResponseBytes response = client.getObject(request, ResponseTransformer.toBytes()); - return response.asUtf8String(); - } - - @Override - protected Map getMultipleValues(String path) { - if (bucket == null) { - throw new IllegalStateException("A bucket must be specified, using withBucket() method"); - } - - ListObjectsV2Request listRequest = ListObjectsV2Request.builder().bucket(bucket).prefix(path).build(); - List s3Objects = client.listObjectsV2(listRequest).contents(); - - Map result = new HashMap<>(); - s3Objects.forEach(s3Object -> { - result.put(s3Object.key(), getValue(s3Object.key())); - }); - - return result; - } - - @Override - protected void resetToDefaults() { - super.resetToDefaults(); - bucket = null; - } - -} -``` -And then use it like this : - -```java -S3Provider provider = new S3Provider(ParamManager.getCacheManager()); -provider.setTransformationManager(ParamManager.getTransformationManager()); // optional, needed for transformations -String value = provider.withBucket("myBucket").get("myKey"); -``` - -## Annotation -You can make use of the annotation ```@Param``` to inject a parameter value in a variable. - -```java -@Param(key = "/my/parameter") -private String value; -``` -By default it will use ```SSMProvider``` to retrieve the value from AWS System Manager Parameter Store. -You could specify a different provider as long as it extends ```BaseProvider``` and/or a ```Transformer```. -For example: - -```java -@Param(key = "/my/parameter/json", provider = SecretsProvider.class, transformer = JsonTransformer.class) -private ObjectToDeserialize value; -``` - -In this case ```SecretsProvider``` will be used to retrieve a raw value that is then trasformed into the target Object by using ```JsonTransformer```. -To show the convenience of the annotation compare the following two code snippets. - -```java:title=AppWithoutAnnotation.java - -public class AppWithoutAnnotation implements RequestHandler { - - // Get an instance of the SSM Provider - SSMProvider ssmProvider = ParamManager.getSsmProvider();
