如何 return FlightOfferSearch 和 FlightOrder 对象作为 JSON？
How can I return FlightOfferSearch and FlightOrder objects as JSON?
如果我尝试从 Spring Boot REST 控制器的处理程序方法中 return FlightOfferSearch[] 或 FlightOrder 对象，它们似乎无法像我已经创建的更简单的 POJO 那样正确序列化之前曾在 Jackson 处理 JSON 序列化的地方工作过。

我还需要做些什么才能将它们转换为 JSON 格式吗？
我修改了 Java SDK 助手以修复和添加一些东西：
- 修复试图预订搜索的所有航班的错误。
- 添加了一种新方法，允许您使用单个 FlightOfferSearch（而非数组）进行预订
- 我添加了一个从 FlightPrice 对象预订的方法。理论上，您不应该直接从 FlightOfferSearch 预订，您应该在预订前调用 Flight Offers Price API 确认价格和可用性。你可以找到一个例子 here. You can learn more about the flight booking flow in this tutorial.
供您参考，如果我们的任何助手失败，我们所有的 API 都支持 JSON 直接（在字符串或 JsonObject 中）的 post，您可以使用该方法（拿你的对象，在String/JSON中反序列化并直接使用它）。
我发布了新版本的SDK版本4.1.0请更新到这个版本
如果我尝试从 Spring Boot REST 控制器的处理程序方法中 return FlightOfferSearch[] 或 FlightOrder 对象，它们似乎无法像我已经创建的更简单的 POJO 那样正确序列化之前曾在 Jackson 处理 JSON 序列化的地方工作过。

我还需要做些什么才能将它们转换为 JSON 格式吗？
我修改了 Java SDK 助手以修复和添加一些东西：
- 修复试图预订搜索的所有航班的错误。
- 添加了一种新方法，允许您使用单个 FlightOfferSearch（而非数组）进行预订
- 我添加了一个从 FlightPrice 对象预订的方法。理论上，您不应该直接从 FlightOfferSearch 预订，您应该在预订前调用 Flight Offers Price API 确认价格和可用性。你可以找到一个例子 here. You can learn more about the flight booking flow in this tutorial.
供您参考，如果我们的任何助手失败，我们所有的 API 都支持 JSON 直接（在字符串或 JsonObject 中）的 post，您可以使用该方法（拿你的对象，在String/JSON中反序列化并直接使用它）。
我发布了新版本的SDK版本4.1.0请更新到这个版本
