問題描述

我現在正在和這個問題爭斗幾天，我真的很絕望。 我正在升級的舊項目在Tomcat啟動期間給出了以下錯誤消息： 

Configuration problem: Unable to locate NamespaceHandler for namespace
[http://www.springframework.org/schema/context]

為什么不能處理上下文模式？

一些背景資料：

關於這個問題存在很多問題，其中大部分是由於相應的JAR不在類路徑中。 不是我的情況。 該應用程序打包為war並放入Tomcat的webapp文件夾中。 在啟動期間 ，Tomcat將戰爭解壓縮到自己的文件夾中，其中WEB-INF / lib文件夾包含“ spring-context-3.2.1.RELEASE.jar ”文件。

日志文件附加到此問題的末尾。 注意tomcat對於設置屬性'cacheAllowed'為'false'的問題沒有找到匹配的屬性。 在啟動期間。 好像它沒有加載org.apache.catalina.core.StandardContext 。 我的context.xml文件包含以下內容： 

<Context cacheAllowed="false" crossContext="true" debug="0"
    docBase="${project.build.finalName}.war" path="/lup-web" privileged="true"
    reloadable="true">
</Context>

違規文件（ services.xml ）以下列內容開頭： 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans.xsd
           http://www.springframework.org/schema/context 
           http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.mycompany.lup.pages"/>
    <context:component-scan base-package="com.mycompany.lup.messages"/>
    <context:component-scan base-package="com.mycompany.lup.importData"/>
    <context:component-scan base-package="com.mycompany.lup.servlet"/>

    <bean class="com.mycompany.lup.importData.ConversionService">

這是catalina運行的日志：

長話短說......這是無效依賴的另一個問題。 Spring 2.0 jar在CLASSPATH上的某個地方。
