Class DefaultClassMapper

  • All Implemented Interfaces:
    ClassMapper, org.springframework.beans.factory.InitializingBean
    public class DefaultClassMapper
extends java.lang.Object
implements ClassMapper, org.springframework.beans.factory.InitializingBean
    Maps to/from JSON using type information in the MessageProperties; the default name of the message property containing the type is "__TypeId__". An optional property setDefaultType(Class) is provided that allows mapping to a statically defined type, if no message property is found in the message properties. setIdClassMapping(Map) can be used to map tokens in the "__TypeId__" header to classes. If this class is not a Spring-managed bean, call afterPropertiesSet() to set up the class to id mapping.

        defaultType - the defaultType to set.

      • setDefaultMapClass

        public void setDefaultMapClass​(java.lang.Class<?> defaultMapClass)
        Set the type of Map to use. For outbound messages, set the "__TypeId__" header to HashTable. For inbound messages, if the "__TypeId__" header is Hashtable convert to this class.
        Parameters:
        defaultMapClass - the map class.

      • setIdClassMapping

        public void setIdClassMapping​(java.util.Map<java.lang.String,​java.lang.Class<?>> idClassMapping)
        Set a map of type Ids (in the "__TypeId__" header) to classes. For outbound messages, if the class is not in this map, the "__TypeId__" header is set to the fully qualified class name.
