我在 Java 动态 Web 项目中使用了 Spring，它在 Windows 上运行良好，但是在我将它部署到 Ubuntu VM 之后， Controller 不起作用，我还在 Eclipse Windows 上创建了一个 .war 文件并通过 tomcat 管理器部署它但没有用。
然后我只是简单地将具有相同结构的 src 代码复制到 webapps 文件夹，但它似乎只显示 .jsp 页面，它没有将页面映射到 @requestMapping 并调用 Controller 类，我需要做任何设置吗/在 Linux 上配置以使其工作？
打开应用程序后，index.jsp 显示内容，但在单击提交后，它应该通过 <form class="formcolor" action="tiers" method="GET"> 调用 AppDynamicsMain.java Controller 。但它正在寻找要显示的层页面并抛出 HTTP 状态 404 - 未找到:
我在 $CATALINA_HOME/webapps/appd-cp/WebContent/WEB-INF/lib/下有所有需要的 jar 文件，我需要移动它们 $CATALINA_HOME/lib/吗？
非常感谢您的帮助。
P.S:我的 VM 没有 GUI，只能通过终端访问(使用 mobaXterm ssh 到 ip)
我不得不在项目的根目录下创建一个额外的 index.jsp 来调用项目 jsp 文件夹中的 index.jsp:$CATALINA_HOME/webapps/appd-cp/index.jsp:
<html>
<head>
<META http-equiv="refresh" content="0;URL=WebContent/WEB-INF/jsp/index.jsp">
</head>
<body>
</body>
</html>
WebContent/WEB-INF/jsp/index.jsp 中的 index.jsp:
<html>
<head>
<META http-equiv="refresh" content="0;URL=welcome.jsp">
</head>
<body>
</body>
</html>
这是我在 VM 中的项目结构:

最佳答案
问题是使用了重复的 jar 文件。这些 spring jar 文件位于 WEB-INF/lib/:
spring-web-3.0.1.RELEASE.jarorg.springframework.asm-3.1.0.RELEASE.jarorg.springframework.beans-3.1.0.RELEASE.jarorg.springframework.context-3.1.0.RELEASE.jarorg.springframework.core-3.1.0.RELEASE.jarorg.springframework.expression-3.1.0.release.jarorg.springframework.web-3.1.0.RELEASE.jarorg.springframework.web.servlet-3.1.0.RELEASE.jar。
错误的根本原因是java.lang.NoSuchMethodError: org.springframework.web.bind.annotation.RequestMapping.consumes()，其中org.springframework.web。 bind.annotation.RequestMapping.class 是 spring-web-3.0.1.RELEASE.jar 和 org.springframework.web.servlet-3.1.0 中的类。 RELEASE.jar，导致初始化失败。删除 spring-web-3.0.1.RELEASE.jar 解决了问题，应用程序初始化正常。
