Class JacksonJsonSerializer

java.lang.Object

com.couchbase.client.java.codec.JacksonJsonSerializer

All Implemented Interfaces:

JsonSerializer

public class JacksonJsonSerializer
extends Object
implements JsonSerializer

A serializer backed by a user-provided Jackson ObjectMapper.

In order to use this class you must add Jackson to your class path.

Make sure to register JsonValueModule with your ObjectMapper so it can handle Couchbase JsonObject instances.

Likewise, if you're using the Encrypted annotation for Couchbase Field-Level Encryption, make sure to register EncryptionModule.

Example usage without Couchbase Field-Level Encryption:

 ObjectMapper mapper = new ObjectMapper();
 mapper.registerModule(new JsonValueModule());

 ClusterEnvironment env = ClusterEnvironment.builder()
     .jsonSerializer(new JacksonJsonSerializer(mapper))
     .build();
 

Example usage with Couchbase Field-Level Encryption:

 CryptoManager cryptoManager = ...

 ObjectMapper mapper = new ObjectMapper();
 mapper.registerModule(new JsonValueModule());
 mapper.registerModule(new EncryptionModule(cryptoManager));

 ClusterEnvironment env = ClusterEnvironment.builder()
     .cryptoManager(cryptoManager)
     .jsonSerializer(new JacksonJsonSerializer(mapper))
     .build();
