我在哪里指定Spring 3.1中的Jackson SerializationConfig.Feature设置

本文介绍了我在哪里指定Spring 3.1中的Jackson SerializationConfig.Feature设置的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我很困惑为什么使用默认包含的jackson，Spring似乎已经定制了默认的Jackson配置。I'm puzzled as to why using a default inclusion of jackson that Spring seems to have customised the default Jackson configuration.其中一个令人烦恼的设置是 WRITE_DATES_AS_TIMESTAMPS ，杰克逊默认为 true 然而Spring在某处将此更改为 false 并且还提供了日期格式。One setting it's messing with is WRITE_DATES_AS_TIMESTAMPS, the Jackson default is true however Spring has somewhere changed this to false and also provided a date format.世界上哪里这是怎么回事？我希望我的日期保持序列化为数字。Where in the world is this happening? I want my dates to remain serialised as numbers. UPDATE ：原来这不是导致问题的春天，它实际上是休眠代理类造成的问题。出于某种原因，如果hibernate的类型映射为 type =date，它会序列化为日期字符串，但是如果它的 type =timestamp 按预期顺序排列。而不是花太多时间研究这个，我决定暂时将我的所有映射都改为时间戳。UPDATE: Turns out it's not spring that's causing the problem, it's actually hibernates proxy classes causing the problem. For some reason if hibernate has a type-mapping of type="date" it serialises as a date string, though if its type="timestamp" it serialises as expected. Rather than spend too much time looking into this I've decided to just change all my mappings to timestamp for now.推荐答案开始使用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AnnotationMethodHandlerAdapterSee 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); } }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) 这篇关于我在哪里指定Spring 3.1中的Jackson SerializationConfig.Feature设置的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
