我想节省时间，手动编写与如此复杂的JSON对应的Java对象模型

有没有什么工具可以帮助将这个复杂的JSON快速转换成java模型

---

我看了一下，但我认为它没有生成正确的Java POJO。我不是在寻找用于将JSON转换为java对象的库，比如GSON，而是寻找用于生成java模型类的在线工具。

你能看看GSON API吗。我目前正在我的项目中使用它，它对我来说很好…

想想杰克逊图书馆。 只需使用ObjectMapper readValue和writeValue即可

我在过去找到的最好的解释是：

我编写了一个简单的JavaScript工具来自动生成java类文件。它只适用于Chrome浏览器。以下是链接：

从它所吸引的答案来看，这个问题可能需要重新表述，以便更精确。提到jsonschema2pojo，意味着您希望从json生成pojo，即java类，而不是java对象，当您已经有了pojo时，这些对象很简单，并且已经涵盖了：似乎工作得很好。我用您的示例json进行了尝试，它生成了所有相关的类和子类。
