ClassNotFoundException启动tomcat时出错 [英] ClassNotFoundException Error when starting tomcat

问题描述

我试图从eclipse安装tomcat服务器，但是这个错误已经打了很久，我没有找到任何解决方案..

我尝试：

• 向类路径添加spring-context，spring-core，spring-web依赖项。

• 修改项目属性这是我的 web.xml ：

  解决方案

  有问题的类是在spring-web - ????? RELEASE.jar中。转到你的战争，用winzip或7Zip等打开它并在WEB-INF / lib中查找jar，我的猜测是它不存在。如果您使用的maven包含依赖项：
  
  

   <依赖项> 
  < groupId> org.springframework< / groupId> 
  < artifactId> spring-web< / artifactId> 
  < version> $ {or.springframework-version}< / version> 
  < /依赖关系> 
    

  如果您没有使用maven，并且我想像您在Eclipse中这样做，正如您提到的部署程序集，你必须添加你用于使这些jar可用于编译到eclipse版本的库。或者你可以简单地将jar移动到WEB-INF / lib。
  
  

  在为jar文件构建之后检查你的war。

  
  

  I'm trying to setup the tomcat server from eclipse, but this error has beaten me for a long and i didn't find any solution..

  I tried:

  • adding spring-context, spring-core, spring-web dependencies to the classpath.
  • modifying the project properties(Deployment Assembly section).
  • cleaning the tomcat server directory.

  this is my web.xml:

  <?xml version="1.0" encoding="UTF-8"?>
  <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  
      <!-- The definition of the Root Spring Container shared by all Servlets and Filters -->
      <context-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>/WEB-INF/spring/root-context.xml</param-value>
      </context-param>
  
      <!-- Creates the Spring Container shared by all Servlets and Filters -->
      <listener>
          <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
  
      <!-- Processes application requests -->
      <servlet>
          <servlet-name>appServlet</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <init-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
          </init-param>
          <load-on-startup>1</load-on-startup>
      </servlet>
  
      <servlet-mapping>
          <servlet-name>appServlet</servlet-name>
          <url-pattern>/</url-pattern>
      </servlet-mapping>
  
  </web-app>
  

  and this is the tracktrace:

  Please, if you need another thing just let me know.

  解决方案

  The class in question is in spring-web-?????RELEASE.jar. Go to your war and either open it with the likes of winzip or 7Zip and look for the jar in WEB-INF/lib, my guess is that it isn't there. If your using maven include the dependency as:

  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>${or.springframework-version}</version>
  </dependency>
  

  If you're not using maven and I imagine you're doing this in Eclipse as you mentioned deployment assembly, you must add whatever libraries you used to make these jars available to your compile to the eclipse build. Or you can simply move the jar to WEB-INF/lib.

  Check your war after the build for the jar file.
