fastjson 序列化去除空字符串属性

public static String toJSONString(Object object) {
        SerializerFeature[] serializerFeatures = new SerializerFeature[] {
                //格式化时间
                SerializerFeature.WriteDateUseDateFormat
        };
        return JSON.toJSONString(object, new ValueFilter() {
            @Override
            public Object process(Object object, String name, Object value) {
                // 如果名称或者值为null或空字符串，则不序列化该属性
                if (name == null || (name instanceof String && ((String) name).isEmpty()) ||
                        value == null || (value instanceof String && ((String) value).isEmpty())) {
                    return null;
                }
                return value;
            }
        }, serializerFeatures);
    }
