Java 如何从这个示例JSON创建POJO？

我正在尝试从API中为以下JSON创建POJO

当我将其复制并粘贴到中时，我在第5行

“requestId”：string中得到一个错误，它说“有一个问题：无法识别的标记'string'：应为（'true'、'false'或'null'）（第5行，第24列）

如果我将
string
更改为实际的示例字符串，它就可以正常工作。这个json-to-pojo转换器不能处理这种格式的json吗？将所有数据类型改为样本似乎有点乏味

页面上的示例JSON代码使用引号中的数据类型，因此
“string”
而不是
string
。你可以这样做：
（警告！如果您需要字符串以外的其他类型，则以下示例毫无意义！）

有效的json要求字符串值包含在引号中。因此，引用键而不是像->“id”：string这样的值没有多大意义。仔细阅读“在请求正文中，使用以下结构提供数据”“您没有提供任何数据
Ok，但现在您将“布尔”和“整数”之类的内容放在引号中。这不会使POJO中的这些数据类型成为字符串吗？另外，我看到的JSON没有引号中的数据类型，您是否手动添加了这些数据类型？我只看到
“requestId”：字符串，
是的，这是正确的。该工具需要有效的JSON或JSON模式。有效的JSON需要字符串值用引号括起来。您可以通过将
的“里程数”：integer
替换为
的“里程数”：{“type”：“integer”}
来创建您的模式，明白了，谢谢。遗憾的是，它没有以有效的模式格式提供。好的，没错。因此，为了创建POJO，我需要在每个字段中放置一些示例数据，并通过jsonscheme2pojo运行它，然后？Json to Java将生成Java类。但要生成POJO，您需要提供适合Bill的json数据，并使用GSON或其他库来实例化模式生成器生成的类
