public class JsonToObjectTransformer<T>
extends AbstractPayloadTransformer<java.lang.String,T>

Transformer implementation that converts a JSON string payload into an instance of the provided target Class. By default this transformer uses JacksonJsonObjectMapperProvider factory to get an instance of Jackson 1 or Jackson 2 JSON-processor JsonObjectMapper implementation depending on the jackson-databind or jackson-mapper-asl libs on the classpath. Any other JsonObjectMapper implementation can be provided.

Since:

2.0
