今天把一个Java的应用迁移到另一台机器上，结果启动tomcat时报以下错误：

解决方法：
一、
如果在项目中遇到该异常，通常是项目无法下载到spring-beans-2.5.xsd文件而出现的问题，这里的版本号因项目版本而异。
这里需要配置本地的xsd文件，方法如下：
找到你的项目中引用的spring的核心包，spring.jar
用压缩文件打开，找到该路径
org/springframework/beans/factory/xml/
并将这个路径下的xsd文件以下列形式配置到applicationContext.xml文件中，如果有多个配置文件，则全部代替
即以
classpath:/org/springframework/beans/factory/xml/spring-beans-2.5.xsd
代替http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
使得从本地直接读取该配置文件
二、配置文件XML的头部声明，具体根据自己使用的Spring版本决定
<?xml version="1.0" encoding="UTF-8"?>
<!--
- Application context definition for JPetStore's business layer.
- Contains bean references to the transaction manager and to the DAOs in
- dataAccessContext-local/jta.xml (see web.xml's "contextConfigLocation").
