Question

当我尝试在Tomcat上运行项目时出现以下错误。它之前工作但我从1.9.7升级了jackson版本到1.9.13并且在更新maven依赖项后我无法再运行该项目。我试图将杰克逊降级到1.9.7，但没有机会。

我已检查过与此问题相关的所有答案。他们都说我需要定义范围，我已经有了。这是我的servlet-api依赖关系定义。

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>

我在pom.xml中的任何依赖项下都找不到任何servlet-api依赖项。这是我的所有pom.xml。

我花了几个小时来解决这个问题，但是我被卡住了。即使我禁用过滤，我得到另一个与此servlet-api范围问题相关的类强制转换异常。但我找不到任何servlet-api jar。任何帮助都非常感谢。

提前致谢。

最后我开始工作了。

这些依赖项下有tomcat包和servlet包。我只将它们用于com.fasterxml.jackson包。对我感到羞耻。我删除了这两个东西都恢复了正常。感谢Karthikeyan建议检查maven依赖文件夹。
