关于日期转JSON

日期直接转json

  @RequestMapping(value = "/json4",produces = "application/json;charset=utf-8")    //String 的转换格式 produces = "text/html;charset=utf-8"

    @ResponseBody

    public String json4 () throws JsonProcessingException {



        ObjectMapper mapper = new ObjectMapper();

        

        Date date = new Date();



        return mapper.writeValueAsString(date);

    }

配上展示图,可以看到返回的是一个时间戳,下面我们就来**



改进后:

@RequestMapping(value = "/json4",produces = "application/json;charset=utf-8")    //String 的转换格式 produces = "text/html;charset=utf-8"

    @ResponseBody

    public String json4 () throws JsonProcessingException {



        ObjectMapper mapper = new ObjectMapper();

        //为了不返回时间戳，所以我们选择关闭它

        mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS,false);

        //自定义日期格式问题

        final SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-DD HH:MM:SS");

        //设置mapper的指定的日期格式

        mapper.setDateFormat(sdf);



        Date date = new Date();



        return mapper.writeValueAsString(date);

    }

我发了两篇关于json可以看到代码重复过多,且次次抛出异常,所以我将在下一篇博客来进行封装成工具类!
