[英]spring3 build error
我有一個使用struts2和spring 3的Web應用程序。為了配置spring,我使用了eclipse和tomcat中的構建路徑在項目中添加了所需的庫。 我也在web.xml中添加了偵聽器,但是當我想運行該應用程序時,會出現此錯誤:嚴重:配置類org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException類的應用程序偵聽器時出錯:org.springframework.web .context.ContextLoaderListener我在Google上搜索了太多,但沒有任何反應。.有人告訴我確保在應用程序lib和tomacat中都添加spring-web.jar,但是沒有任何改變..請幫助

當eclipse不能正確地將應用程序添加到tomcat服務器時,我經常會遇到org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException
這個問題(通常是在一天中第一次或在更大的svn之后啟動eclipse時發生的查看)
就我而言,這有助於執行一系列操作(始終等待下一步直到完成之前的步驟!)
如果您有自由,我建議使用maven而不是手動在Eclipse類路徑周圍擺弄。 您可以按照以下簡單步驟進行操作:
mvn archetype:generate -DgroupId=com.test -DartifactId=test -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
這將生成所需的Maven項目結構。 然后如下所示編輯pom.xml文件。

構建項目:
mvn clean package
並生成eclipse配置源文件:
mvn eclipse:eclipse -DdownloadSources=true
此步驟足以創建項目結構,該項目結構在類路徑中具有必需的庫,並附帶源。
最后,您可以在Eclipse中導入項目。
File > Import > General > Existing project into Workspace > Select the project directory
您可以從http://maven.apache.org/download.cgi下載並安裝Maven。
我看到您使用eclipse wtp插件運行Web應用程序,然后您可以在文件系統中找到擴展Web應用程序,並檢查lib目錄中是否裝有spring.jar,您也可以看到此我的應用程序沒有看到ContextLoaderListener
