dom4j解析xml⽂件时忽略DOCTYPE标签
利⽤dom4j读取xml配置⽂件时，如果⽂件中出现DOCTYPE标签，可能会在read时读取异常：
Document document = ad(file);
导致⽂件读取失败，如下：
Exception in thread "main" org.dom4j.DocumentException: Error on line 1 of document /testng-1.0.dtd : ⽂档类型声明包含或指向的标记声明必须格 at org.dom4j.ad(SAXReader.java:482)

特别是l时，如果不添加则⽆法正常运⾏程序。
<!DOCTYPE suite SYSTEM "/testng-1.0.dtd" >
百度实验了各种解决⽅案都⽆法解决，最后终于到了⼀种适⽤的忽略dtd⽂件的⽅法（查询的另外⼏种统统未解决），贴上解决的代码以
供参考：
//获得⽂件
File file = new File(filePath);
//利⽤dom4j读取xml
SAXReader reader = new SAXReader();
//忽略dtd⽂件校验
reader.setValidation(false);
reader.setEntityResolver(new EntityResolver() {
@Override
public InputSource resolveEntity(String publicId, String systemId) throws SAXException, IOException {
return new InputSource(new ByteArrayInputStream("<?xml version='1.0' encoding='UTF-8'?>".getBytes()));            }
});
完美解决，以供参考谢谢。
