java使用Jdom实现xml文件写入操作实例
本文实例讲述了java使用Jdom实现xml文件写入操作的方法。分享给大家供大家参考，具体如下：
packagecom.yanek.demo.xml.test;
importjava.io.File;
importjava.io.FileWriter;
importorg.jdom.Attribute;
importorg.jdom.Document;
importorg.jdom.Element;
importorg.jdom.input.SAXBuilder;
importorg.jdom.output.XMLOutputter;
publicclassJdomWriteXml{
/**
*@paramargs
*/
publicstaticvoidmain(String[]args){
SAXBuildersb=newSAXBuilder();
Elementactions=newElement("actions");
Documentdocument=newDocument(actions);
Elementaction1=newElement("action");
actions.addContent(action1);
Attributepath_atbt1=newAttribute("path","/test");
Attributeclass_atbt1=newAttribute("class",
"com.mystruts.demo.LoginAction");
action1.setAttribute(path_atbt1);
action1.setAttribute(class_atbt1);
Elementaction1_forward1=newElement("forward");
action1.addContent(action1_forward1);
Attributeaction1_forward1_name_atbt1=newAttribute("name","success");
Attributeaction1_forward1_url_atbt1=newAttribute("url","test.jsp");
action1_forward1.setAttribute(action1_forward1_name_atbt1);
action1_forward1.setAttribute(action1_forward1_url_atbt1);
Elementaction1_forward2=newElement("forward");
action1.addContent(action1_forward2);
Attributeaction1_forward1_name_atbt2=newAttribute("name","failure");
Attributeaction1_forward1_url_atbt2=newAttribute("url",
"failure.jsp");
action1_forward2.setAttribute(action1_forward1_name_atbt2);
action1_forward2.setAttribute(action1_forward1_url_atbt2);
Elementaction2=newElement("action");
actions.addContent(action2);
Attributepath_atbt2=newAttribute("path","/user");
Attributeclass_atbt2=newAttribute("class",
"com.mystruts.demo.UserAction");
action2.setAttribute(path_atbt2);
action2.setAttribute(class_atbt2);
Elementaction2_forward1=newElement("forward");
action2.addContent(action2_forward1);
Attributeaction2_forward1_name_atbt1=newAttribute("name","success");
Attributeaction2_forward1_url_atbt1=newAttribute("url","test.jsp");
action2_forward1.setAttribute(action2_forward1_name_atbt1);
action2_forward1.setAttribute(action2_forward1_url_atbt1);
Elementaction2_forward2=newElement("forward");
action2.addContent(action2_forward2);
Attributeaction2_forward1_name_atbt2=newAttribute("name","failure");
Attributeaction2_forward1_url_atbt2=newAttribute("url",
"failure.jsp");
action2_forward2.setAttribute(action2_forward1_name_atbt2);
action2_forward2.setAttribute(action2_forward1_url_atbt2);
Attributeroot_atbt1=newAttribute("m","001");
actions.setAttribute(root_atbt1);
try{
Filef1=newFile("mystruts.xml");
//XMLOutputterxo=newXMLOutputter("",true,"GB2312");
XMLOutputterxo=newXMLOutputter();
FileWriterfw=newFileWriter(f1);
xo.output(document,fw);
fw.close();
}catch(Exceptione){
e.printStackTrace();
}
//System.out.println(document.toString());
}
}
生成xml文件：
<?xmlversion="1.0"encoding="UTF-8"?> <actionsm="001"> <actionpath="/test"class="com.mystruts.demo.LoginAction"> <forwardname="success"url="test.jsp"/> <forwardname="failure"url="failure.jsp"/> </action> <actionpath="/user"class="com.mystruts.demo.UserAction"> <forwardname="success"url="test.jsp"/> <forwardname="failure"url="failure.jsp"/> </action> </actions>
