Dom4J UTF-8 编码问题解决方案......

这几天用到了xml技术但是发现了个问题就是无法以UTF-8保存xml文件，保存后再次读出的时候会报“Invalid byte 2 of 2-byte UTF-8 sequence.”这样一个错误

 

试着使用GBK、gb2312编码来生成的xml文件却可以正常的被解析。

 

后来在网上找到前辈的资料。

 public void createXML(String fileName) {

        Document doc = org.dom4j.DocumentHelper.createDocument();

        Element root = doc.addElement("book");

        root.addAttribute("name", "我的图书");

 

        Element childTmp;

        childTmp = root.addElement("price");

        childTmp.setText("21.22");

 

        Element writer = root.addElement("author");

        writer.setText("李四");

        writer.addAttribute("ID", "001");

 

        try {

            org.dom4j.io.XMLWriter xmlWriter = new org.dom4j.io.XMLWriter(

                    new FileWriter(fileName));

            xmlWriter.write(doc);

            xmlWriter.close();

        }

        catch (Exception e) {

            System.out.println(e);

        }

    }

 

 

改为这个就行了。

public void createXML(String fileName) {

        Document doc = org.dom4j.DocumentHelper.createDocument();

        Element root = doc.addElement("book");

        root.addAttribute("name", "我的图书");

 

        Element childTmp;

        childTmp = root.addElement("price");

        childTmp.setText("21.22");

 

        Element writer = root.addElement("author");

        writer.setText("李四");

        writer.addAttribute("ID", "001");

 

        try {
            //注意这里的修改

            org.dom4j.io.XMLWriter xmlWriter = new org.dom4j.io.XMLWriter(

                   new FileOutputStream(fileName));

            xmlWriter.write(doc);

            xmlWriter.close();

        }

        catch (Exception e) {

            System.out.println(e);

        }

    }

 

 

 

就这样就行了、、、、、忙也不多说了，呵呵希望对你们有帮助。
