Method Details

getTypePrecedence

public Jackson2JavaTypeMapper.TypePrecedence getTypePrecedence()

Return the precedence.

Specified by:

getTypePrecedence in interface Jackson2JavaTypeMapper

Returns:

the precedence.

Since:

1.6.

See Also:

• setTypePrecedence(Jackson2JavaTypeMapper.TypePrecedence)

setTypePrecedence

public void setTypePrecedence(Jackson2JavaTypeMapper.TypePrecedence typePrecedence)

Set the precedence for evaluating type information in message properties. When using @RabbitListener at the method level, the framework attempts to determine the target type for payload conversion from the method signature. If so, this type is provided in the inferredArgumentType message property.

By default, if the type is concrete (not abstract, not an interface), this will be used ahead of type information provided in the __TypeId__ and associated headers provided by the sender.

If you wish to force the use of the __TypeId__ and associated headers (such as when the actual type is a subclass of the method argument type), set the precedence to Jackson2JavaTypeMapper.TypePrecedence.TYPE_ID.

Parameters:

typePrecedence - the precedence.

Since:

1.6

setTrustedPackages

public void setTrustedPackages(@Nullable
 String... trustedPackages)

Specify a set of packages to trust during deserialization. The asterisk (*) means trust all.

Parameters:

trustedPackages - the trusted Java packages for deserialization

Since:

1.6.11

addTrustedPackages

public void addTrustedPackages(@Nullable
 String... packages)

Description copied from interface: Jackson2JavaTypeMapper

Add trusted packages.

Specified by:

addTrustedPackages in interface Jackson2JavaTypeMapper

Parameters:

toJavaType

public com.fasterxml.jackson.databind.JavaType toJavaType(MessageProperties properties)

Description copied from interface: Jackson2JavaTypeMapper

Determine the type from the message properties.

Specified by:

toJavaType in interface Jackson2JavaTypeMapper

Parameters:

properties - the properties.

Returns:

the type.

getInferredType

@Nullable
public com.fasterxml.jackson.databind.JavaType getInferredType(MessageProperties properties)

Description copied from interface: Jackson2JavaTypeMapper

Return the inferred type, if the type precedence is inferred and the header is present.

Specified by:

getInferredType in interface Jackson2JavaTypeMapper

Parameters:

properties - the message properties.

Returns:

the type.

fromJavaType

public void fromJavaType(com.fasterxml.jackson.databind.JavaType javaType,
 MessageProperties properties)

Description copied from interface: Jackson2JavaTypeMapper

Set the message properties according to the type.

Specified by:

Parameters:

javaType - the type.

properties - the properties.

fromClass

public void fromClass(Class<?> clazz,
 MessageProperties properties)

Specified by:

fromClass in interface ClassMapper

toClass

public Class<?> toClass(MessageProperties properties)

Specified by:
