为日期反序列化设置杰克逊时区 [英] Set Jackson Timezone for Date deserialization

问题描述

我正在使用 Jackson(通过 Spring MVC Annotations)将字段从 JSON 反序列化为 java.util.Date.POST 看起来像 - {"enrollDate":"2011-09-28T00:00:00.000Z"}，但是当对象由 Spring & 创建时Jackson 将日期设置为 "2011-09-27 20:00:00".

I'm using Jackson (via Spring MVC Annotations) to deserialize a field into a java.util.Date from JSON. The POST looks like - {"enrollDate":"2011-09-28T00:00:00.000Z"}, but when the Object is created by Spring & Jackson it sets the date as "2011-09-27 20:00:00".

如何在 Jackson 中设置正确的时区?或者如果这不是问题，我如何从 JSON 消息发送 EST?

Javascript/jQuery:

var personDataView = { enrollDate : new Date($("#enrollDate").val()), 
                       //...other members
                      };


$.postJSON('/some/path/', personDataView, function(data){
    //... handle the response here

});

JSON 消息:

{"enrollDate":"2011-09-28T00:00:00.000Z"}

弹簧控制器:

@RequestMapping(value="/", method=RequestMethod.POST)
public @ResponseBody String saveProfile(@RequestBody personDataView persondataView, HttpServletRequest request)
{
        //...dataView has a java.util.Date enrollDate field
        //...other code
}

推荐答案

在Jackson 2+中，你也可以使用@JsonFormat注解:

In Jackson 2+, you can also use the @JsonFormat annotation:

@JsonFormat(shape=JsonFormat.Shape.STRING, pattern="yyyy-MM-dd'T'HH:mm:ss.SSSZ", timezone="America/Phoenix")
private Date date;

如果这种方式不起作用，请尝试用单引号包裹 Z，即 pattern=yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"

If it doesn't work this way then try wrapping Z with single quotes, i.e. pattern="yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"
