对于一个项目，我正在使用带有 kafka 的 Spark 结构化流。
我有这个配置：
<spark.version>3.1.1</spark.version>
<slf4j.version>1.7.7</slf4j.version>
<log4j.version>1.2.17</log4j.version>
<scala.version>2.12</scala.version>
但是当我运行时，我遇到了这个错误：
原因：com.fasterxml.jackson.databind.JsonMappingException：Scala 模块 2.12.3 需要 Jackson Databind 版本 >= 2.12.0 且 < 2.13.0
我很困惑，因为我已经在 2.12.3 中导入了 databind。 就在这里，我的 pom.xml 的摘录：
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-yaml</artifactId>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.module</groupId>
<artifactId>jackson-module-scala_${scala.version}</artifactId>
<version>2.12.3</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.12.3</version>
</dependency>
提前感谢您的帮助
Allen D.Ball，我的回答太长，无法发表评论。所以， pom.xml：

您确定有错误吗？ Scala 2.12 需要 Jackson 2.10.x.
要调试，请运行
mvn dependency:tree如果您正在构建 Spring 项目（具有父 POM spring-boot-dependency），请设置：
<jackson-bom.version>2.10.5.20201202</jackson-bom.version>
满足 Scala 要求的最新 Jackson。否则，您需要将以下内容添加到您的
<dependencyManagement/> <dependencyManagement>
<dependencies>
...
<dependency>
<groupId>com.fasterxml.jackson</groupId>
<artifactId>jackson-bom</artifactId>
<version>${jackson-bom.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
...
</dependencies>
</dependencyManagement>
并从 Jackson 依赖项中删除
<version>
