Constructor Detail

JsonbHttpMessageConverter

public JsonbHttpMessageConverter()

Construct a new JsonbHttpMessageConverter with default configuration.

JsonbHttpMessageConverter

public JsonbHttpMessageConverter(javax.json.bind.JsonbConfig config)

Construct a new JsonbHttpMessageConverter with the given configuration.

Parameters:

config - the JsonbConfig for the underlying delegate

JsonbHttpMessageConverter

public JsonbHttpMessageConverter(javax.json.bind.Jsonb jsonb)

Construct a new JsonbHttpMessageConverter with the given delegate.

Parameters:

jsonb - the Jsonb instance to use

Method Detail

setJsonb

public void setJsonb(javax.json.bind.Jsonb jsonb)

Set the Jsonb instance to use. If not set, a default Jsonb instance will be created.

Setting a custom-configured Jsonb is one way to take further control of the JSON serialization process.

getJsonb

public javax.json.bind.Jsonb getJsonb()

Return the configured Jsonb instance for this converter.
