解組JSON爲String，BigInteger和BigDecimal與傑克遜非常接近

Question

我們使用的是傑克遜，我看到這個代碼

DeserializationConfig.Feature.USE_BIG_DECIMAL_FOR_FLOATS 
DeserializationConfig.Feature.USE_BIG_INTEGER_FOR_INTS 

但是我如何才能傑克遜現在是將這些功能？

這將是完美的情況。我只想要一個帶有String，BigDecimal和BigIntegers的Map結果。

Answer 1

Enable the feature on the ObjectMapper.

ObjectMapper mapper = new ObjectMapper(); 
mapper.enable(DeserializationConfig.Feature.…); 

Update for version >= 2.0.0:

ObjectMapper mapper = new ObjectMapper(); 
mapper.enable(DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS); 
mapper.enable(DeserializationFeature.USE_BIG_INTEGER_FOR_INTS);
