Spring Boot ignore ObjectMapper module

问题

In application context I have registered an ObjectMapper module:

@Bean
public SimpleModule jsr310Module() {
    final SimpleModule module = new SimpleModule();
    module.addSerializer(new LocalDateSerializer());
    module.addDeserializer(LocalDate.class, new LocalDateDeserializer());
    return module;
}

I tried to debug and it is loaded (or at least the method public void setupModule(SetupContext context) is execute on boot) but when I call a rest API that return an object with a LocalDate my deserializer is ignored.

Some hint to solve the problem?

回答1:

To make it work the @Configuration class should extend WebMvcAutoConfiguration

回答2:

According to the Spring Boot documentation, to configure the ObjectMapper you can either define the bean yourself and annotate it with @Beanand @Primary. There you can register the module. Or you can add a bean of type Jackson2ObjectMapperBuilderwhere you can customize the ObjectMapper.
