Class MapJsonSerializer

java.lang.Object

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

All Implemented Interfaces:

org.springframework.core.serializer.Deserializer<java.util.Map<?,?>>, org.springframework.core.serializer.Serializer<java.util.Map<?,?>>

public class MapJsonSerializer
extends java.lang.Object
implements org.springframework.core.serializer.Serializer<java.util.Map<?,?>>, org.springframework.core.serializer.Deserializer<java.util.Map<?,?>>

Serializes a Map as JSON. Deserializes JSON to a Map. The default JacksonJsonObjectMapperProvider.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
