本例使用的xml解析方式为jdom
...
<ROOT>
<Consignment>
...
</Consignment>
</ROOT>
解析xml文件
InputStream xmlFileStream = new FileInputStream(xmlFile);
SAXBuilder builder = new SAXBuilder(new XMLReaderSAX2Factory(false));
Document document = builder.build(xmlFileStream);
Element root = document.getRootElement();
获得Consignment元素
Element consignElement = root.getChild("Consignment");
遍历元素封装Bean
public static Consignment getConsignment(Element consignElement) throws Exception {
Consignment consignment = null;
try {
List<Element> elements = consignElement.getChildren();
Class<?> consignmentClz = Class.forName("com.entity.po.consignment.Consignment");
consignment = (Consignment) consignmentClz.newInstance();
for(Element ele : elements){
CheckTypeUtil.checkType(consignment, consignmentClz, ele);
}
} catch (Exception e) {
throw e;
}
return consignment;
}
