com.fasterxml.jackson.databind.ser.BeanSerializerFactory

Factory class that can provide serializers for any regular Java beans (as defined by "having at least one get method recognizable as bean accessor" -- where {@link Object#getClass} does not count);as well as for "standard" JDK types. Latter is achieved by delegating calls to {@link BasicSerializerFactory} to find serializers both for "standard" JDK types (and in some cases, sub-classes as is the case for collection classes like {@link java.util.List}s and {@link java.util.Map}s) and bean (value) classes.

Note about delegating calls to {@link BasicSerializerFactory}: although it would be nicer to use linear delegation for construction (to essentially dispatch all calls first to the underlying {@link BasicSerializerFactory}; or alternatively after failing to provide bean-based serializer}, there is a problem: priority levels for detecting standard types are mixed. That is, we want to check if a type is a bean after some of "standard" JDK types, but before the rest. As a result, "mixed" delegation used, and calls are NOT done using regular {@link SerializerFactory} interface but rather viadirect calls to {@link BasicSerializerFactory}.

Finally, since all caching is handled by the serializer provider (not factory) and there is no configurability, this factory is stateless. This means that a global singleton instance can be used.

    
    public void testFindExplicit() throws JsonMappingException
    {
        ObjectMapper mapper = new ObjectMapper();
        SerializationConfig config = mapper.getSerializationConfig();
        SerializerFactory f = new BeanSerializerFactory(null);
        DefaultSerializerProvider prov = new DefaultSerializerProvider.Impl().createInstance(config, f);


        // Should have working default key and null key serializers
        assertNotNull(prov.findKeySerializer(mapper.constructType(String.class), null));
        assertNotNull(prov.getDefaultNullKeySerializer());
