net.sf.json 格式化 Date

其他类型同理

Date 为格式化前 createDate":{"date":4,"day":2,"hours":17,"minutes":18,"month":7,"seconds":34,"time":1249377514000,"timezoneOffset":-480,"year":109}

JsonConfig cfg = new JsonConfig();
   cfg.registerJsonValueProcessor(java.util.Date.class,new JsonValueProcessor() {
    private final String format="yyyy-MM-dd";
    public Object processObjectValue(String key, Object value,
      JsonConfig arg2)
    {
     if(value==null)
      return "";
     if (value instanceof Date) {
      String str = new SimpleDateFormat(format).format((Date) value);
      return str;
     }
     return value.toString();
    }

    public Object processArrayValue(Object value, JsonConfig arg1)
    {
     return null;
    }
   });
JSONArray json = JSONArray.fromObject(a,cfg);
