如何修复javax。servlet。ServletException:Servlet。Tomcat的init（）错误

Question

问题是错误似乎只出现在我的Linux服务器上（Tomcat 9.0.22）。在Windows上根本没有问题（Tomcat 9.0.27）。服务器本身似乎是工作的，就在我试图调用应用程序的REST应用编程接口时，出现了这个奇怪的错误（重新恐惧堆栈跟踪）。

如果我错过了任何重要的信息，只是aks我，我很乐意提供它。

提前谢谢你，Sollder1。

Answer 1

Servlet.init（）异常通常与依赖版本控制有关。

您不应该在依赖项上使用最新版本。杰克逊核心，更具体地说。可能您的应用程序在Linux服务器中使用了不同的、不兼容的杰克逊核心版本。

这个答案解释了为什么使用最新版本是一个问题。您应该始终使用特定版本以避免兼容性问题。

Answer 2

好的，

问题解决后，运行mvn dependency:tree-DVerbose命令并找到坏男孩。在我的例子中是javax。ws。rs:jsr311 api来自依赖项io。招摇过市：招摇过市

我解决了这个问题，包括以下排除：

        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-jaxrs</artifactId>
            <version>1.5.0</version>

            <exclusions>
                <exclusion>
                    <groupId>javax.ws.rs</groupId>
                    <artifactId>jsr311-api</artifactId>
                </exclusion>
            </exclusions>

        </dependency>

谢谢你的帮助！
