xml与javabean的相互转换
引用开源包：dom4j
jar包 ：见附件
功能 ：主要用于开发中常见的xml与javabean之间的数据互转，减少重复代码的编写，支持xml对应字段中的集合数据类型(只能为list)。但不支持 bean转换成xml时不指定字段所对应xml元素结点名称的情况，所有的字段必需指定生成xml时所对应的结点名称(即使想字段名就是xml结点属性名)。
example:
要转换成bean对象的xml文件
<?xml version='1.0' encoding='UTF-8'?> <result resultCode="0" ses="5"> <dd>1212</dd> <getDiskResult> <nodeCount>43</nodeCount> <contentList length="35"> <contentInfo> <contentID>xb11RJTmc01109020111028015344009</contentID> <contentName>1-1稻城风光.docx</contentName> <contentList length="35"> <contentInfo> <contentID> xb11RJTmc01109020111028015344009 </contentID> <contentName>1-2-11稻城风光.docx</contentName> </contentInfo> <contentInfo> <contentID> xb11RJTmc01109020111028015344010 </contentID> <contentName>1-2-12稻城风光.docx</contentName> </contentInfo> </contentList> </contentInfo> <contentInfo> <contentID>xb11RJTmc01109020111028015344009</contentID> <contentName>2-1稻城风光.docx</contentName> <contentList length="35"> <contentInfo> <contentID> xb11RJTmc01109020111028015344009 </contentID> <contentName>2-2-11稻城风光.docx</contentName> </contentInfo> <contentInfo> <contentID> xb11RJTmc01109020111028015344010 </contentID> <contentName>2-2-12稻城风光.docx</contentName> </contentInfo> </contentList> </contentInfo> </contentList> </getDiskResult> </result>
java实体bean对象（一定要提供get set方法）

}
}
ContentInfoChild.java
public class ContentInfoChild {
@ElementAnnotation(xmlElement = "contentID")
private String id;
@ElementAnnotation(xmlElement = "contentName")
private String name;
public String getId() {
return id;

public void setId(String id) {

}
测试MyTest.java类
public class MyTest {
public static void main(String[] args){
InputStream in = MyAnalyMain.class.getClassLoader().getResourceAsStream("ce.xml");
Content content = null;
Long begin = System.currentTimeMillis();
XmlToBeanAnaly analy = new XmlToBeanAnaly(); //xml转换成实现bean的
analy.setClass(Content.class); //设置要转换成xml的bean的class信息
analy.initBeanFields(); //初使化字段数据
//bean转换成xml文件
BeanToXmlAnaly toXml = new BeanToXmlAnaly();
toXml.setEncodeing("utf-8", "root");
try {
toXml.setSchema("your scheama path", "public url");
//Content content = analy.xmlToBean(in,Content.class); //当没有调用 setClass（）与initBeanFields（）方法时可调用此方法
content = analy.xmlToBean(in); //将xml转换成bean
System.out.println(content);
Long end = System.currentTimeMillis();
System.out.println("执行耗时："+(end - begin));
//bean转换成xml文件
String xml = toXml.beanToXmlString(content);
System.out.println(xml);
} catch (Exception e) {
e.printStackTrace();
}
}
}
输出：
System.out.println(content);
System.out.println("执行耗时："+(end - begin));

ps：附件己重新更新，用法和文章介绍差不多。只是注解里的属性名有所更改，同时修正了几处bug。同时添加了根据bean中的字段类型自动转换数据(现只支持String ,Boolean,Double,Float等常用类型)，当字段与xml结点或属性名相同时默认不用指定名称。
