java.lang.Object
  org.mule.transformer.AbstractTransformer
      org.mule.transformer.AbstractMessageAwareTransformer
          org.mule.module.json.transformers.AbstractJsonTransformer
              org.mule.module.json.transformers.ObjectToJson

All Implemented Interfaces:

MuleContextAware, Initialisable, NamedObject, BaseTransformer, DiscoverableTransformer, Transformer

public class ObjectToJson
extends AbstractJsonTransformer

Converts a java object to a JSON encoded object that can be consumed by other languages such as Javascript or Ruby.

The JSON engine can be configured using the jsonConfig attribute. This is an object reference to an instance of: net.sf.json.JsonConfig. This can be created as a spring bean.

Users can configure a comma-separated list of property names to exclude or include i.e. excludeProperties="address,postcode".

The returnClass for this transformer is always java.lang.String, there is no need to set this.
