控制器在将应用程序从Windows部署到Linux后不工作

分类: 技术问答 • 2022-05-25 10:10:02
问题描述：

我在一个Java动态Web项目中使用了Spring，它在Windows上工作正常，但是在将它部署到Ubuntu VM后，控制器无法正常工作，我也创建了一个。战争文件在Eclipse Windows上，并通过tomcat管理器部署它，但没有奏效。控制器在将应用程序从Windows部署到Linux后不工作

然后我简单地将我的src代码与相同的结构复制到webapps文件夹，但似乎只显示了.jsp页面，它不会将页面映射到@requestMapping并调用控制器类，是否需要执行任何操作在Linux上安装/配置，使其工作？

打开应用程序后，index.jsp显示内容，但点击提交后，它应该通过<form class="formcolor" action="tiers" method="GET">调用AppDynamicsMain.java控制器，但它正在寻找分层页面来显示并抛出HTTP状态404 - 未找到：

error page I get

我都在$ CATALINA_HOME/webapps /下APPD-CP/M的WebContent所需的jar文件/ WEB-INF/lib目录/，我需要移动它们$ CATALINA_HOME/lib中/？

非常感谢您的帮助。

PS：我的虚拟机没有GUI，

我不得不做出一个额外的index.jsp在我的项目的根作出一个电话，只有通过访问终端（SSH到IP使用mobaXterm） index.jsp的项目JSP文件夹中：$ CATALINA_HOME/webapps /下APPD-CP/index.jsp的：

<html> 
     <head> 

      <META http-equiv="refresh" content="0;URL=WebContent/WEB-INF/jsp/index.jsp"> 

     </head> 

     <body> 
     </body> 
</html>

的index.jsp在的WebContent/WEB-INF/JSP/index.jsp的：

<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：

appd-cp 
    |->index.jsp 
    |->src 
    | -->com.sh 
    |  --->AppDynamicsMain.java  
    |->WebContent

    |   ---->graphCPU.jsp 
    |  --->CapacityPlanning-servlet.xml 
    |  --->web.xml

日志中的任何错误？我看到你的应用问题。 WEB-INF下的文件无法从外部访问。例如'URL = WebContent/WEB-INF/jsp/index.jsp'不会起作用。你能否看到你的应用程序是否成功部署？您应该能够打包.war并部署到Apache/Tomcat？ –

@MinhKieu，我可以访问welcome.jsp页面，从项目根目录下的index.jsp调用URL = WebContent/WEB-INF/jsp/index.jsp，访问url没有任何问题。 – gr8code2be

你能否看到你是否可以从根文件夹访问文件？正如我所说，根据我的经验，WEB-INF目录下的内容不能直接从外部世界访问。它受servlet容器保护。如果这是您手动创建的目录，那么我建议您检查文件权限。 –

问题是使用重复的jar文件。这些弹簧jar文件是在WEB-INF/lib中/：

  • spring-web-3.0.1.RELEASE.jar
  • org.springframework.asm-3.1.0.RELEASE.jar
  • org.springframework.beans-3.1.0.RELEASE.jar
  • org.springframework.context-3.1.0.RELEASE.jar
  • org.springframework.core-3.1.0.RELEASE.jar
  • org.springframework.expression-3.1.0.release.jar
  • org.springframework.web-3.1.0.RELEASE.jar
  • org.springframework.web.servlet-3.1.0.RELEASE.jar。

和错误的根本原因是java.lang.NoSuchMethodError: org.springframework.web.bind.annotation.RequestMapping.consumes()，其中org.springframework.web.bind.annotation.RequestMapping.class在两个spring-web-3.0.1.RELEASE.jar和org.springframework.web.servlet-3.1.0.RELEASE.jar一类，导致初始化失败。删除spring-web-3.0.1.RELEASE.jar解决了问题，并且应用程序初始化就好了。
