Direct Known Subclasses:

DefaultSerializerProvider
```
public abstract class SerializerProvider
extends DatabindContext
```
Class that defines API used by ObjectMapper and JsonSerializers to obtain serializers capable of serializing instances of specific types; as well as the default implementation of the functionality.
Provider handles caching aspects of serializer handling; all construction details are delegated to SerializerFactory instance.
Object life-cycle is such that an initial instance ("blueprint") is created and referenced by ObjectMapper and ObjectWriter intances; but for actual usage, a configured instance is created by using a create method in sub-class DefaultSerializerProvider. Only this instance can be used for actual serialization calls; blueprint object is only to be used for creating instances.

                                                     throws JsonMappingException
```
    Method called to get hold of a serializer for a value of given type; or if no such serializer can be found, a default handler (which may do a best-effort generic serialization or just simply throw an exception when invoked).
    Note: this method is only called for non-null values; not for keys or null values. For these, check out other accessor methods.
    Note that serializers produced should NOT handle polymorphic serialization aspects; separate TypeSerializer is to be constructed by caller if and as necessary.
    
    Throws:
    
    JsonMappingException - if there are fatal problems with accessing suitable serializer; including that of not finding any serializer
  - findValueSerializer
```
public JsonSerializer<java.lang.Object> findValueSerializer(JavaType valueType,

```
    Similar to findValueSerializer(Class,BeanProperty), but takes full generics-aware type instead of raw class. This is necessary for accurate handling of external type information, to handle polymorphic types.
    Note: this call will also contextualize serializer before returning it.
    
    Parameters:
    
    property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

```
    Similar to findValueSerializer(JavaType, BeanProperty), but used when finding "primary" property value serializer (one directly handling value of the property). Difference has to do with contextual resolution, and method(s) called: this method should only be called when caller is certain that this is the primary property value serializer.
    
    Parameters:
    
    property - Property that is being handled; will never be null, and its type has to match valueType parameter.

```
    Method called to locate regular serializer, matching type serializer, and if both found, wrap them in a serializer that calls both in correct sequence. This method is currently only used for root-level serializer handling to allow for simpler caching. A call can always be replaced by equivalent calls to access serializer and type serializer separately.
    
    Parameters:
    
    valueType - Type for purpose of locating a serializer; usually dynamic runtime type, but can also be static declared type, depending on configuration
    
    cache - Whether resulting value serializer should be cached or not; this is just a hint
    
    property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

    Method called to locate regular serializer, matching type serializer, and if both found, wrap them in a serializer that calls both in correct sequence. This method is currently only used for root-level serializer handling to allow for simpler caching. A call can always be replaced by equivalent calls to access serializer and type serializer separately.
    
    Parameters:
    
    valueType - Declared type of value being serialized (which may not be actual runtime type); used for finding both value serializer and type serializer to use for adding polymorphic type (if any)
    
    cache - Whether resulting value serializer should be cached or not; this is just a hint
    
    property - When creating secondary serializers, property for which serializer is needed: annotations of the property (or bean that contains it) may be checked to create contextual serializers.

```
    Method called to get the serializer to use for serializing non-null Map keys. Separation from regular findValueSerializer(java.lang.Class<?>, com.fasterxml.jackson.databind.BeanProperty) method is because actual write method must be different (@link JsonGenerator#writeFieldName}; but also since behavior for some key types may differ.

    Method called to get the serializer to use for serializing null values for specified property.

    Typically, returned serializer will throw an exception, although alternatively ToStringSerializer could be returned as well.

  - isUnknownTypeSerializer

    Method that can be called to construct and configure serializer instance, either given a Class to instantiate (with default constructor), or an uninitialized serializer instance.
