Package org.springframework.integration.ip.tcp.serializer

Class MapJsonSerializer

java.lang.Object

org.springframework.integration.ip.tcp.serializer.MapJsonSerializer

All Implemented Interfaces:

Deserializer<Map<?,?>>, Serializer<Map<?,?>>

public class MapJsonSerializer
extends Object
implements Serializer<Map<?,?>>, Deserializer<Map<?,?>>

Serializes a Map as JSON. Deserializes JSON to a Map. The default JsonObjectMapperProvider.newInstance() can be overridden using setJsonObjectMapper(JsonObjectMapper).

The JSON deserializer can't delimit multiple JSON objects. Therefore, another (de)serializer is used to apply structure to the stream. By default, this is a simple ByteArrayLfSerializer, which inserts/expects LF (0x0a) between messages.

Since:

3.0

setJsonObjectMapper

public void setJsonObjectMapper(JsonObjectMapper<?,?> jsonObjectMapper)

An JsonObjectMapper to be used for the conversion to/from JSON. Use this if you wish to set additional JsonObjectMapper implementation features.

Parameters:

jsonObjectMapper - the jsonObjectMapper.

setPacketDeserializer

public void setPacketDeserializer(Deserializer<byte[]> packetDeserializer)

A Deserializer that will construct the full JSON content from the stream which is then passed to the JsonObjectMapper. Default is ByteArrayLfSerializer.

Parameters:

packetDeserializer - the packetDeserializer

setPacketSerializer

public void setPacketSerializer(Serializer<byte[]> packetSerializer)

A Serializer that will delimit the full JSON content in the stream. Default is ByteArrayLfSerializer.
