gson无法正常将时间戳转化成date

#Java #Gson

gson无法正常将时间戳转化成date

gson将时间戳转化成date时，报错

Failed to parse date ["1551950239757']: Invalid time zone indicator '3'

解决办法

添加一个long转date的解析器

		@Test
    public void fun1(){

        GsonBuilder builder = new GsonBuilder();

        // Register an adapter to manage the date types as long values
        builder.registerTypeAdapter(Date.class, new JsonDeserializer<Date>() {
            public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
                return new Date(json.getAsJsonPrimitive().getAsLong());
            }
        });

        Gson gson = builder.create();


        String str = "{\"name\":\"yjt\",\"date\":\"1552012460277\"}";
        Person person = gson.fromJson(str,Person.class);
        log.info("{}", person);
    }
