存在时抛出 Jackson UnrecognizedPropertyException

Question

我有一个使用 bott 2.0.0.0 的基本 spring 引导独立可执行 jar 我认为这很简单，但 Google 不会放弃答案。 :) 我正在使用最新的稳定 jackson 版本 (2.9.4)，但它们由 spring 管理。这是一道布尔题：

这里是 JSON 我正试图变成一个 Java Pojo（它被包裹在一个更高的对象中，但我不认为那是问题所在。我在布尔值上有问题.

我收到一条错误消息，指出没有名为 "isSuspend" 的字段，如您所见，它就在那里（第 3 行），甚至设置为 false。这是我的 pojo:

Answer 1

问题可能是因为字段 isSuspend 的 getter 和 setter 名称？尝试命名 getter 和 setter getIsSuspend 和 setIsSuspend

Answer 2

您的 POJO 不遵循 Java Beans 命名约定。如果您希望 Jackson 不查看 getters/setters，而只查看字段，请参见：how to specify jackson to only use fields - preferably globally
