使用dom4j来生成XML文件
packageio.xml;
importjava.io.File;
importjava.io.FileNotFoundException;
importjava.io.FileOutputStream;
importjava.io.IOException;
importjava.io.OutputStreamWriter;
importjava.io.UnsupportedEncodingException;
importorg.dom4j.Document;
importorg.dom4j.DocumentHelper;
importorg.dom4j.Element;
importorg.dom4j.io.OutputFormat;
importorg.dom4j.io.XMLWriter;
//由java对像生成XML文件
publicclassXMLDemo
{
publicstaticvoidmain(String[]args)
{
Documentdocument=DocumentHelper.createDocument();
Elementroot=document.addElement("root");
Elementstudents=root.addElement("students");
Filefile=newFile("F:\\temp\\test.xml");
if(file.exists())
{
file.delete();
}
Student[]stu=newStudent[5];
for(inti=0;i<5;i++)
{
stu[i]=newStudent("name"+i,"id"+i,i*100);
}
try
{
for(intj=0;j<stu.length;j++)
{
ElementstuElement=students.addElement("student");
stuElement.addElement("name").addText(stu[j].getName());
stuElement.addElement("id").addText(stu[j].getId());
stuElement.addElement("height").addText(String.valueOf(stu[j].getHeight()));
}
FileOutputStreamfileStream=newFileOutputStream(file);
OutputStreamWriteroutputStreamWriter=newOutputStreamWriter(fileStream,"UTF-8");
OutputFormatformat=newOutputFormat();
format.setIndent(true);///缩排
format.setIndent("");//缩排长度
format.setNewlines(true);//折行
XMLWriterwriter=newXMLWriter(outputStreamWriter,format);
writer.write(document);
outputStreamWriter.close();
fileStream.close();
writer.close();
System.out.println("success....");
}
catch(UnsupportedEncodingExceptione)
{
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
catch(FileNotFoundExceptione)
{
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
catch(IOExceptione)
{
//TODOAuto-generatedcatchblock
e.printStackTrace();
}
}
}
==================
生成的结果如下;
<?xmlversion="1.0"encoding="UTF-8"?>
<root>
<students>
<student>
<name>name0</name>
<id>id0</id>
<height>0</height>
</student>
<student>
<name>name1</name>
<id>id1</id>
<height>100</height>
</student>
<student>
<name>name2</name>
<id>id2</id>
<height>200</height>
</student>
<student>
<name>name3</name>
<id>id3</id>
<height>300</height>
</student>
<student>
<name>name4</name>
<id>id4</id>
<height>400</height>
</student>
</students>
</root>
