Question

问题在于，错误仅在我将其部署到Linux服务器（Tomcat 9.0.22）时才出现。在Windows上根本没有问题（Tomcat 9.0.27）。服务器本身似乎可以正常工作，只是当我尝试调用应用程序的REST API时，就会出现此奇怪的错误（请参阅Stacktrace）。

Answer 1

好吧

问题已解决，请运行mvndependency：tree -DVerbose命令并找到坏男孩。在我的情况下，它是io.swagger：swagger-jaxrs依赖项中的javax.ws.rs:jsr311-api

我通过以下排除方式解决了这个问题：

        <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>

感谢您的帮助！

Answer 2

Servlet.init（）异常通常与依赖项版本控制有关。

您不应在依赖项上使用最新版本。更具体地说，杰克逊·科尔。可能您的应用程序在Linux服务器中使用了另一种不兼容的Jackson Core版本。

This answer解释了为什么使用LATEST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。
