XmlUtil类:
不多说,直接撸代码:
/** * java 转换成xml * @Title: toXml * @Description: TODO * @param obj 对象实例 * @return String xml字符串 */ public static String toXml(Object obj){ XStream xstream=new XStream(); // XStream xstream=new XStream(new DomDriver()); //直接用jaxp dom来解释 // XStream xstream=new XStream(new DomDriver("utf-8")); //指定编码解析器,直接用jaxp dom来解释 ////如果没有这句,xml中的根元素会是<包.类名>;或者说:注解根本就没生效,所以的元素名就是类的属性 xstream.processAnnotations(obj.getClass()); //通过注解方式的,一定要有这句话 return xstream.toXML(obj); }
/** * 将传入xml文本转换成Java对象 * @Title: toBean * @Description: TODO * @param xmlStr * @param cls xml对应的class类 * @return T xml对应的class类的实例对象 * * 调用的方法实例:PersonBean person=XmlUtil.toBean(xmlStr, PersonBean.class); */ public static <T> T toBean(String xmlStr, Class<T> cls){ //注意:不是new Xstream(); 否则报错:java.lang.NoClassDefFoundError: org/xmlpull/v1/XmlPullParserFactory XStream xstream=new XStream(new DomDriver()); xstream.ignoreUnknownElements(); xstream.processAnnotations(cls); T obj=(T)xstream.fromXML(xmlStr); return obj; }
/** * 写到xml文件中去 * @Title: writeXMLFile * @Description: TODO * @param obj 对象 * @param absPath 绝对路径 * @param fileName 文件名 * @return boolean */ public static boolean toXMLFile(Object obj, String absPath, String fileName ){ String strXml = toXml(obj); String filePath = absPath + fileName; File file = new File(filePath); if(!file.exists()){ try { file.createNewFile(); } catch (IOException e) { logger.error("创建{"+ filePath +"}文件失败!!!" , e); return false ; } }// end if OutputStream ous = null ; try { ous = new FileOutputStream(file); ous.write(strXml.getBytes()); ous.flush(); } catch (Exception e1) { logger.error("写{"+ filePath +"}文件失败!!!" ,e1); return false; }finally{ if(ous != null ) try { ous.close(); } catch (IOException e) { logger.error("写{"+ filePath +"}文件关闭输出流异常!!!" ,e); } } return true ; }
