处理 DateTime 的 CustomJacksonMapper 配置在 Spring 4.1.5 上不起作用

Configuration of CustomJacksonMapper to deal with DateTime is not working on Spring 4.1.5

以下是我所做的配置:

我的配置文件:

<mvc:annotation-driven>
    <mvc:message-converters>
        <!-- Support for Joda Time -->
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper" ref="customJacksonMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven> 

我的 class 扩展了 Object

@Component("customJacksonMapper")
public class CustomJacksonMapper extends ObjectMapper {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;

/**
 * Instantiates a new custom jackson mapper.
 * 
 * RegisterModule = Registar o módulo do JodaTime.
 * Locale = Padrão portugues Brasil.
 * TimeZone = Converte para o timezone de São Paulo.
 * 
 */
public CustomJacksonMapper() {
    this.registerModule(new JodaModule());
    this.setLocale(new Locale("pt_BR"));
    this.setTimeZone(TimeZone.getTimeZone("America/Sao_Paulo"));
    this.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS , false);
    this.setSerializationInclusion(JsonInclude.Include.NON_NULL);
}

}

使用此配置,正如我在很多帖子中所读到的,日期应该以 Json 中的正确格式返回,但我得到的是以下内容:

{"date": 1467920285301}

我做错了什么?

尝试将这一行添加到构造函数中:

this.setDateFormat(new ISO8601DateFormat());

我将 Spring 项目的版本更新为 4.2.6 RELEASE。这样做解决了我的问题。
