Example 1 with DeserializerFactory

use of com.fasterxml.jackson.databind.deser.DeserializerFactory in project flink by apache.

the class AWSUtil method setAwsClientConfigProperties.

/**
 * Set all prefixed properties on {@link ClientConfiguration}.
 *
 * @param config
 * @param configProps
 */
public static void setAwsClientConfigProperties(ClientConfiguration config, Properties configProps) {
    Map<String, Object> awsConfigProperties = new HashMap<>();
    for (Map.Entry<Object, Object> entry : configProps.entrySet()) {
        String key = (String) entry.getKey();
        if (key.startsWith(AWS_CLIENT_CONFIG_PREFIX)) {
            awsConfigProperties.put(key.substring(AWS_CLIENT_CONFIG_PREFIX.length()), entry.getValue());
        }
    }
    // Jackson does not like the following properties
    String[] ignorableProperties = { "secureRandom" };
    BeanDeserializerModifier modifier = new BeanDeserializerModifierForIgnorables(ClientConfiguration.class, ignorableProperties);
    DeserializerFactory factory = BeanDeserializerFactory.instance.withDeserializerModifier(modifier);
    ObjectMapper mapper = new ObjectMapper(null, null, new DefaultDeserializationContext.Impl(factory));
    JsonNode propTree = mapper.convertValue(awsConfigProperties, JsonNode.class);
    try {
        mapper.readerForUpdating(config).readValue(propTree);
    } catch (IOException ex) {
        throw new RuntimeException(ex);
    }
