http://ibatis.apache.org/dtd/ibatis-3-config.dtd Cause: java.net.ConnectException: Connection timed out: connect

最近发现我的一个web项目只要在家启动时候就出现一个连接错误的问题，大概如下：

Context initialization failed

经过IDE的代码异常提示，在配置文件applicationContext.xml的头文件中有一个头提示无法访问，于是copy 地址http://ibatis.apache.org/dtd/ibatis-3-config.dtd再浏览器中访问，果然请求超时，通过google发现更改地址就行了，在此记录下：

在配置文件中，将http://ibatis.apache.org/dtd/ibatis-3-config.dtd更改为http://mybatis.org/dtd/mybatis-3-config.dtd
