问题描述
我的一个java web项目非常奇怪， 只要在家里编码启动的时候就偶尔报错。如下是错误信息是咋回事，在公司从未出现过这个问题，在家里已经出现过好几次了。Context initialization failedorg.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML

解决方案
context初始化失败，应该是你配置文件中 配置的dtd需要从网络上获取，获取不到 超时导致
解决方案二：
SAXBuilder和SAXReader解析xml时，会根据你xml文件DOCTYPE中的dtd验证文件路径，到网络上寻找该文件，当查找该文件失败或网络有异常时，就会抛出连接超时。看错误信息是spring读取配置文件，获取网络dtd文件连接超时抛出异常，spring默认使用jaxp.DocumentBuilderImpl解析xml，可以有多种方式解决这个问题最简单明了的方式是下载dtd到本地（下载路径即是你当前配置的路径），放到configurations.xml同一目标，并且修改configurations.xml的DOCTYPE如下模式<!DOCTYPE beans SYSTEM "spring-beans.dtd">当然更简单的方式是使用XSD代替dtd，spring的jar包中自带xsd定义文件，因此不需要联网也能执行验证
解决方案三：
time out把configurations.xml的内容发出来看下
解决方案四：
调高timeout，试试！
解决方案五：
连接timeout 了，就是连接超时了，网络问题
解决方案六：
网络问题吧，nested exception is java.net.ConnectException: Connection timed out: connect
解决方案七：
网络链接超时。
