json - jackson2 JSON ISO 8601来自JodaTime in Spring 3.2RC1

我正在开发SpringMVC 3.2RC1中的RESTAPI。
我正在获取一个包含org.joda.time.datetime时间戳的JPA实体，并让Spring使用

@RequestMapping(value = "/foobar", method = RequestMethod.GET, produces = "application/json")
@ResponseBody

在Spring中使用默认的jackson2设置，正如我刚添加的那样

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.1.1</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.1.1</version>
</dependency>
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.1.1</version>
</dependency>

到我的绒球上，让弹簧把它自己绑起来。
控制器正在生成：

"created":{"year":2012,"dayOfMonth":30,"dayOfWeek":5,"era":1,"dayOfYear":335,"weekOfWeekyear":48,"weekyear":2012,"monthOfYear":11,"yearOfEra":2012,"yearOfCentury":12,"centuryOfEra":20,"millisOfSecond":39,"millisOfDay":52684039,"secondOfMinute":4,"secondOfDay":52684,"minuteOfHour":38,"minuteOfDay":878,"hourOfDay":14,"millis":1354282684039,"zone":{"uncachedZone":{"cachable":true,"fixed":false,"id":"Europe/Stockholm"},"fixed":false,"id":"Europe/Stockholm"},"chronology":{"zone":{"uncachedZone":{"cachable":true,"fixed":false,"id":"Europe/Stockholm"},"fixed":false,"id":"Europe/Stockholm"}},"afterNow":false,"beforeNow":true,"equalNow":false}

但我希望它是和ISO8601日期一样的2007-11-16t20:14:06.3z（或带偏移）。
我的猜测是我需要访问Objectmapper并设置mapper.enable（serializationFeature.write_dates_as_timestamps）；但是使用时如何访问Objectmapper

<mvc:annotation-driven />

另外，我使用jpa/hibernate4将对象持久化到postgresql，使用usertype获得jodatime支持。D.S.
更新
下面的配置为java.util.date解决了这个问题，但jodatime仍然没有骰子。

<annotation-driven>
    <message-converters>
        <beans:bean
            class="org.springframework.http.converter.StringHttpMessageConverter" />
        <beans:bean
            class="org.springframework.http.converter.ResourceHttpMessageConverter" />
        <beans:bean
            class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <beans:property name="objectMapper">
                <beans:bean
                    class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean"
                    p:indentOutput="true" p:simpleDateFormat="yyyy-MM-dd'T'HH:mm:ss.SSSZ">
                </beans:bean>
            </beans:property>
        </beans:bean>
    </message-converters>
</annotation-driven>

最佳答案

或者，如果你喜欢在Java中做你的配置，它可以是这样的：

@Configuration
@EnableWebMvc
public class RestConfig extends WebMvcConfigurerAdapter {

    private ObjectMapper objectMapper() {
        Jackson2ObjectMapperFactoryBean bean = new Jackson2ObjectMapperFactoryBean();
        bean.setIndentOutput(true);
        bean.setSimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
        bean.afterPropertiesSet();
        ObjectMapper objectMapper = bean.getObject();
        objectMapper.registerModule(new JodaModule());
        return objectMapper;
    }

    private MappingJackson2HttpMessageConverter mappingJackson2HttpMessageConverter() {
        MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        converter.setObjectMapper(objectMapper());
        return converter;
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        converters.add(mappingJackson2HttpMessageConverter());
    }

}
