使用dom4j解析自定义的.xml文件.
大致内容如下:
居然报了一个 连接超时的错误:

解决方案:
后面找到了其中的原因:
是网络的问题.因为DOCTYPE的连接不同造成的.
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
使用了saxreader解析器的时候,会自动解析DOCTYPE里面的内容.如果连接不上网络,则会报连接超时的异常.
所以为了,不然解析DOCTYPE,则reader.setFeature(不加载dtd文件,false); 就不会去解析DOCTYPE了.
即可.
SAXReader reader = new SAXReader();
reader.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
Connection timed out: connect Nested exception
