jsonlib对date类型的双向转换
jsonlib里toBean对格式化的日期进行转换：JSON-Java

JSONObject json = JSONObject.fromObject(str);
		JSONUtils.getMorpherRegistry().registerMorpher(new DateMorpher(new String[]{"yyyy-MM-dd HH:mm:ss"}));
		App app = (App) json.toBean(json, App.class);
		System.out.println(app.getCreateTime());

jsonlib里toJson将日期格式化掉：Java-Json

JsonConfig config = new JsonConfig();
		config.registerJsonValueProcessor(Date.class, new JsonValueProcessor() {
			
			private SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
			@Override
			public Object processObjectValue(String key, Object value, JsonConfig cfg) {
				return format.format((Date)value);
			}
			
			@Override
			public Object processArrayValue(Object value, JsonConfig cfg) {
				return format.format((Date)value);
			}
		});

fromObject的时候携带上这个config即可
