java解析xml文件

dom4j默认的读取和写入编码是ISO-8859-1

//读取 File file = new File("路径"): FileInputStream in = new FileInputStream(file); Reader reader = new InputStreamReader(in,"utf-8"); SAXReader saxReader = new SAXReader(); saxReader.read(reader); //写入 FileOutputStream out = new FileOutputStream(file); Writer writer = new OutputStreamWriter(out,"utf-8"); document.writer(writer);

 

 

解析的xml文件内容片段如下

<?xml version='1.0' encoding='UTF-8'?>
<hibernate-configuration>
	<session-factory>
	<property name="connection.url">
		jdbc:oracle:thin:@192.168.0.1:1521:oral
	</property>
	<property name="connection.username">test</property>
	<property name="connection.password">123</property>
	</session-factory>
</hibernate-configuration>

 

java代码片段如下

String path = getServletContext().getRealPath("/") 
	+ "WEB-INF/classes/hibernate."; 
File file = new File(path + area + ".xml"); 
SAXReader reader = new SAXReader(); 
Document doc = reader.read(file); 
Element sf = doc.getRootElement().element("session-factory"); 
for(Iterator<element> ite = sf.elementIterator();ite.hasNext();) { 
	Element e = ite.next(); 
	if (e.attributeValue("name").equals("connection.url")) { 
	System.out.println(e.getTextTrim()); } 
	else if(e.attributeValue("name").equals("connection.username")) { 
	System.out.println(e.getTextTrim()); } 
	else if(e.attributeValue("name").equals("connection.password")) { 
	System.out.println(e.getTextTrim()); } 
}
