我在WildFly上运行的项目中的依赖项有问题。 在pom中.xml我对杰克逊库依赖有以下定义：
<dependencyManagement>
// ....
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.10.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>2.10.2</version>
</dependency>
// ...
</dependencyManagement>
但在运行时使用的是 2.1.4 版。我也在 IntelliJ 中看到它，它告诉我这个版本"因与 2.1.4 冲突而被省略">
版本2.1.4 包含在 WildFly 中，但我想使用版本 2.10.2。如何强制使用此版本库？

我找到了解决方案。在 WildFly 18.0.1 上一切正常，因为它包含杰克逊库的 2.9.10.1 版本。问题出在 WildFly 8.2.1 上，因为它包含版本 2.1.4。运行时使用的杰克逊库版本是WildFly提供的版本。
参考这个问题： 野蝇 9 - 如何排除杰克逊 我将文件 jboss-deployment-structure.xml 添加到我的 META-INF 目录中，并具有以下连续性：
<jboss-deployment-structure>
<deployment>
<exclusions>
<module name="com.fasterxml.jackson.core.jackson-core" />
<module name="com.fasterxml.jackson.core.jackson-databind" />
<module name="com.fasterxml.jackson.core.jackson-annotations" />
<module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider" />
<module name="org.jboss.resteasy.resteasy-jackson2-provider" />
</exclusions>
</deployment>
</jboss-deployment-structure>
不幸的是，它仅适用于 WildFly 18.0.1，WildFly 8.2.1 由于其他依赖问题而无法启动，因此在这种情况下最合理的解决方案是升级 WildFly 或从 pom 中删除 jackson-datatype-jsr310.xml
