我在演示项目中使用改造库进行调用。

我收到以下错误：

java.lang.NumberFormatException：应为 int，但在第 1 行第 8454 列路径 $.result.results.ads[2].acres 为 0.6

我理解这取决于 GSON。

我将向您展示它陷入的 JSON：

       "auction_date":0,
       "tags":1
    },

我对改造不是很有经验，所以决定学习和整合这个项目。

有人有什么建议吗？

我无法控制向下发送的 JSON。

尝试使用floatordouble代替int; 0.6不是整数，是小数。请注意，java 自动将小数解释为doubles; 浮点数的一个例子是0.6f.

那是因为解析器期望的是 aint而它得到的实际值是float. 您可以做的是，在您的模型中将该值的类型从int更改为。float

无论您在哪里使用该值，这都可能导致代码出现问题。您可以通过将该浮点值转换为整数来解决它。
