Question

I am porting jackson 1.6 code to jackson 2 and stumbled upon a deprecated code.

What i did in jackson 1.6 is:

CustomDeserializerFactory sf = new CustomDeserializerFactory();
mapper.setDeserializerProvider(new StdDeserializerProvider(sf));
sf.addSpecificMapping(BigDecimal.class, new BigDecimalDeserializer());
t = mapper.readValue(ts, X[].class);

Anyone knows how to do it in jackson 2?

Answer 1

In Jackson 2.0:

1. Create a Module (usually SimpleModule)
2. Register custom handlers with it.
3. Call ObjectMapper.registerModule(module);.

This is available on Jackson 1.x as well (since 1.8 or so).
