Question

我正在使用 Spring Boot 和 Json Deserializer 来运行 kafka Consumer。运行应用程序时我收到错误

我正在使用 spring-boot 3.0.5 和 jackson-databing 2.15.0。有人遇到过同样的错误吗？

我试图调试这个问题，它似乎与我的域对象包含枚举类型作为属性这一事实有关。Jackson 扫描对象的结构并急切地加载每种类型的反序列化器，当到达枚举类型时它会失败。有谁知道我如何跟踪和解决问题？

Answer 1

看起来它是2.15.0通过 github 上的这个线程发布的。

将其添加'com.fasterxml.jackson.core:jackson-annotations:2.15.0'到依赖项中可以修复它。感谢@Wenod 指出了这一点。

Answer 2

java.lang.NoSuchFieldError：READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE

不知何故，您似乎在类路径上有旧版本的 jackson-annotations jar；它应该与数据绑定 jar 版本相同。

这是一个新的枚举值JsonFormat.Feature：

   /**
     * Override for <code>DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE</code>,
     * which allows unknown Enum values to be ignored and a predefined value specified through
     * {@link com.fasterxml.jackson.annotation.JsonEnumDefaultValue @JsonEnumDefaultValue} annotation.
     *
     * @since 2.15
     */
    READ_UNKNOWN_ENUM_VALUES_USING_DEFAULT_VALUE,
