All Implemented Interfaces:

public class MappingVaultConverter
extends AbstractVaultConverter

VaultConverter that uses a MappingContext to do sophisticated mapping of domain objects to SecretDocument. This converter converts between Map-typed representations and domain objects without use of a JSON library. SecretDocument is the input to JSON mapping to exchange secrets with Vault.

MappingVaultConverter

public MappingVaultConverter(MappingContext<? extends VaultPersistentEntity<?>,VaultPersistentProperty> mappingContext)

Method Detail

setTypeMapper

public void setTypeMapper(VaultTypeMapper typeMapper)

Configures the VaultTypeMapper to be used to add type information to SecretDocuments created by the converter and how to lookup type information from SecretDocuments when reading them. Uses a DefaultVaultTypeMapper by default. Setting this to null will reset the TypeMapper to the default one.

Parameters:

typeMapper - the typeMapper to set, must not be null.

getMappingContext

public MappingContext<? extends VaultPersistentEntity<?>,VaultPersistentProperty> getMappingContext()

read

public <S> S read(Class<S> type,
                  SecretDocument source)

readMap

protected Map<Object,Object> readMap(TypeInformation<?> type,
                                     Map<String,Object> sourceMap)

Reads the given Map into a Map. will recursively resolve nested Maps as well.

Parameters:

type - the Map TypeInformation to be used to unmarshall this Map.

sourceMap - must not be null

Returns:

write

public void write(Object source,
                  SecretDocument sink)

writeInternal

protected void writeInternal(Object obj,
                             org.springframework.vault.repository.convert.SecretDocumentAccessor sink,
                             @Nullable
                             TypeInformation<?> typeHint)

Internal write conversion method which should be used for nested invocations.

Parameters:

obj -

sink -

typeHint -

writeInternal

protected void writeInternal(Object obj,
                             org.springframework.vault.repository.convert.SecretDocumentAccessor sink,
                             VaultPersistentEntity<?> entity)

writePropertyInternal

protected void writePropertyInternal(@Nullable
                                     Object obj,
                                     org.springframework.vault.repository.convert.SecretDocumentAccessor accessor,
                                     VaultPersistentProperty prop)

createCollection

protected List<Object> createCollection(Collection<?> collection,
                                        VaultPersistentProperty property)

Writes the given Collection using the given VaultPersistentProperty information.

Parameters:

collection - must not be null.

property - must not be null.

Returns:

createMap

protected Map<String,Object> createMap(Map<Object,Object> map,
                                       VaultPersistentProperty property)

Writes the given Map using the given VaultPersistentProperty information.

Parameters:

map - must not null.

property - must not be null.

Returns:

writeMapInternal

protected Map<String,Object> writeMapInternal(Map<Object,Object> obj,
                                              Map<String,Object> bson,
                                              TypeInformation<?> propertyType)

Writes the given Map to the given Map considering the given TypeInformation.

Parameters:

obj - must not be null.

bson - must not be null.

propertyType - must not be null.

Returns:

addCustomTypeKeyIfNecessary

protected void addCustomTypeKeyIfNecessary(@Nullable
                                           TypeInformation<?> type,
                                           Object value,
                                           org.springframework.vault.repository.convert.SecretDocumentAccessor accessor)

Adds custom type information to the given SecretDocument if necessary. That is if the value is not the same as the one given. This is usually the case if you store a subtype of the actual declared type of the property.

Parameters:

type -

value - must not be null.

accessor - must not be null.
