Configuring Jackson mapper when using Dropwizard
JavaTimeModule is registered by default in Dropwizard 1.0.0 and above. For previous versions, the dropwizard-java8 bundle provided support for Java 8 features. Java 8 is the baseline for Dropwizard 1.0.0, and the bundle was merged into baseline.
Assuming you use Dropwizard 1.0.0 or above, if you still need to access the ObjectMapper, you can do it in your Application<T>:
- in method
void initialize(Bootstrap<T> bootstrap), viabootstrap.getObjectMapper() - in method
abstract void run(T configuration, Environment environment), viaenvironment.getObjectMapper()
That way, you can register other modules, or enable or disable Jackson features. Some of them impact how Java 8 types are serialized and deserialized.
