Spring boot Struts2无法在可执行war-嵌入式Tomcat中初始化Dispatcher

我正在将一个webapp从JBoss迁移到嵌入式Tomcat。它在intellij上工作，但当我使用

java-jar myapplication.war运行
war
文件时，它显示以下错误。谷歌搜索之后，我找不到任何解决办法。这个问题似乎有两个
struts2 core
jar或一些相互冲突的依赖项，但我只有一个jar

样本项目

错误：

StrutsServlet

战争结构最终版

我真的被困在这个和IntelliJ上了，效果很好。我不知道为什么Struts已经创建了一个bean，名为
Struts
，类型为
com.opensymphony.xwork2.ObjectFactory

有人知道吗？
要从maven项目中生成可执行的jar或war，您应该使用


org.springframework.boot
在本页或本页上

66.2打包可执行jar和war文件
一旦
springbootmaven插件
包含在您的
pom.xml中
将自动尝试重写存档以使其可执行
使用
springboot:repackage
目标。您应该配置您的
使用通常的
包装元素：


罐子

您现有的存档将通过Spring引导在

阶段。要启动的主类可以是
使用配置选项指定，或通过添加
主类指定
属性以通常的方式添加到清单。如果不指定
主类插件将搜索带有
publicstaticvoidmain（String[]args）
method

要构建和运行项目工件，可以键入以下内容：

$mvn包
$java-jar目标/mymodule-0.0.1-SNAPSHOT.jar

我找到了解决办法

虽然它看起来像一个重复的jar问题，但事实并非如此。问题是：tomcat容器为同一个文件提供了两个不同的路径。不同的前缀路径jar:file://和jar:war:file://

Bean-jar:file:/C:/target/spring-boot-struts2-0.0.1-SNAPSHOT.war已经加载了名为spring的Bean类型类com.opensymphony.xwork2.ObjectFactory/WEB-INF/lib/struts2-spring-plugin-2.3.34.jar/struts plugin.xml:29:132-bean-jar:war:file:/C:/target/spring-boot-struts2-0.0.1-SNAPSHOT.war*/WEB-INF/lib/struts2-spring-plugin-2.3.34.jar/struts plugin.xml:29:132

为了解决这个问题，我刚刚将struts2核心和struts2 spring插件范围从compile更改为provided。spring boot maven插件将这些文件放在使用java-jar myapplication.war运行时提供的WEB-INF/lib下。这些jar是在运行时提供的。
它是在框架启动时由调度程序创建的。如果失败，那么您的配置或依赖项就有问题。我相信这是我在maven上的打包构建中的问题，因为当我构建为可执行的jar时，Struts启动良好，并且调用了操作，但我不能使用可执行的jar，因为它不提供JSP页面，如果我把src\main\webapp文件夹放在jar文件的同一个目录中，它就会找到JSP页面。你不能，因为你没有找到它们。对不起，我不明白。我想建立一个可执行的战争。难道这不可能吗？你是如何建立一个可执行的战争的？谢谢罗曼C！这正是我一直在做的，但它没有正常工作。不，你没有。它不适合你，因为你没有正确阅读这个答案。
