你可以配置提供商的顺序，但实际上***在这种情况下使用一个提供商：

You can configure the order of providers, but it would actually be best to use one provider in this situation:

@Provider
public class JacksonMapperProvider implements ContextResolver<ObjectMapper> {
    private final ObjectMapper defaultMapper;
    private final ObjectMapper specializedMapper;

    public JacksonMapperProvider() {
        defaultMapper = createDefaultMapper();
        specializedMapper = createSpecializedMapper();
    }

    private static ObjectMapper createDefaultMapper() {
        return new ObjectMapper()
            .setSerializationInclusion(Include.ALWAYS)
            .configure(JsonParser.Feature.ALLOW_COMMENTS, true)
            .configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true)
            .configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES, true)
            .configure(JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);
    }

    private static ObjectMapper createSpecializedMapper() {
        return new ObjectMapper()
            .disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
            .setDateFormat(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS"))
            .registerModule(new SpecializedModule1())
            .registerModule(new SpecializedModule2());
    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        if (SomeType.isAssignableFrom(type)) {
            return specializedMapper;
        }
        else {
            return defaultMapper;
        }
    }
}
