public class FastJsonConfig {
	public static final SerializerFeature[] features = {
		SerializerFeature.WriteMapNullValue, // 输出空置字段
		SerializerFeature.WriteNullListAsEmpty, // list字段如果为null，输出为[]，而不是null
		SerializerFeature.WriteNullNumberAsZero, // 数值字段如果为null，输出为0，而不是null
		SerializerFeature.WriteNullBooleanAsFalse, // Boolean字段如果为null，输出为false，而不是null
		SerializerFeature.WriteNullStringAsEmpty,// 字符类型字段如果为null，输出为""，而不是null
		SerializerFeature.WriteMapNullValue //MAP为null输出空
	};
	
	
}

String json = JSON.toJSONStringWithDateFormat(menuList, "yyyy-MM-dd HH:mm:ss",FastJsonConfig.features);
