今天部署项目时，无限次启动tomcat ，但是项目一直没有被加载，让我十分苦恼，看了下tomcat 日志 才发现报了以下的问题

这个问题就是因为启动项目是需要去spring的官网验证下，但是当时的服务器环境被限制了 ，只能连接部分网站，并不包括spring 官网，于是百度了一下 发现可以.xsd文件的连接改成本地的 例如：

xsi:schemaLocation="http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-4.2.xsd
    http://www.springframework.org/schema/aop classpath:org/springframework/aop/config/spring-aop-4.2.xsd
    http://www.springframework.org/schema/tx classpath:org/springframework/transaction/config/spring-tx-4.2.xsd
    http://www.springframework.org/schema/context classpath:org/springframework/context/config/spring-context-4.2.xsd"

但是这样下来 ，如果需要改动的地方比较多的话，工作量还是很大的，然后在某一篇博文上看到 这么一句话：

**spring在加载xsd文件时总是先试图在本地查找xsd文件(spring的jar包中已经包含了所有版本的xsd文件)**

于是突发奇想把 把版本号降低 因为他会优先查找本地。

xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">

这样就ok了 。算是偷了点懒吧
