开始使用3.1 M1，您可以通过 mvc：annotation-driven 的子元素注册 HttpMessageConverters 来指定jackson自定义配置。

Starting with 3.1 M1 you can specify jackson custom configuration by registering an HttpMessageConverters through a sub-element of mvc:annotation-driven.

参见 Spring 3.1 MVC命名空间改进

参见 SPR-7504 更容易添加新内容消息转换器到AnnotationMethodHandlerAdapter

See SPR-7504 Make it easier to add new Message Converters to AnnotationMethodHandlerAdapter

例如：

<bean id="jacksonObjectMapper" class="x.y.z.CustomObjectMapper">                
</bean>

<mvc:annotation-driven>
    <mvc:message-converters>
       <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
           <property name="objectMapper" ref="jacksonObjectMapper" />
       </bean>
       </mvc:message-converters>
</mvc:annotation-driven>

CustomObjectMapper对象

The CustomObjectMapper Object

    @Component("jacksonObjectMapper")
    public class CustomObjectMapper extends ObjectMapper {

        @PostConstruct
        public void afterPropertiesSet() throws Exception {

            SerializationConfig serialConfig = getSerializationConfig()     
                        .withDateFormat(null);

                  //any other configuration

            this.setSerializationConfig(serialConfig);
        }
    }

SerializationConfig。 withDateFormat

SerializationConfig .withDateFormat

除了使用指定的日期格式构建实例外，还将启用或禁用
Feature.WRITE_DATES_AS_TIMESTAMPS（如果格式设置则启用as null;如果非null则禁用）

In addition to constructing instance with specified date format, will enable or disable Feature.WRITE_DATES_AS_TIMESTAMPS (enable if format set as null; disable if non-null)
