更改com.sun.org.apache.xml.internal.serialize.XMLSerializer和com.sun.org.apache.xml.internal.serialize.OutputFormat

Question

使用com.sun.org.apache.xml.internal.serialize.XMLSerializer和com.sun.org.apache.xml.internal.serialize.OutputFormat使用Java 1.6进行编译时会导致一些错误。我发现的解决方案是使用xerces org.apache.xml.serialize.XMLSerializer并org.apache.xml.serialize.OutputFormat添加xerces之后。问题是这些类已被弃用。在不接触代码的情况下，不用替换它们又能做什么？Thnx这是我使用的依赖项：

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.9.1</version>
</dependency>

我们可以使用org.w3c.dom.ls包中的LSSerializer类

public String toXML(Node source) {

    String subscrXML=null;
    StringWriter stringWriter=new StringWriter();
     try {
        //Get the implementations

        DOMImplementationRegistry registry =  DOMImplementationRegistry.newInstance();

        DOMImplementationLS impls =  (DOMImplementationLS)registry.getDOMImplementation("LS");


        //Prepare the output
        LSOutput domOutput = impls.createLSOutput();
        domOutput.setEncoding(java.nio.charset.Charset.defaultCharset().name());            
        domOutput.setCharacterStream(stringWriter);
        domOutput.setEncoding(ENCODING);
        //Prepare the serializer
        LSSerializer domWriter = impls.createLSSerializer();            
        DOMConfiguration domConfig = domWriter.getDomConfig();
        domConfig.setParameter("format-pretty-print", true);
        domConfig.setParameter("element-content-whitespace", true);
        domWriter.setNewLine("\r\n");     
        domConfig.setParameter("cdata-sections", Boolean.TRUE);
        //And finaly, write
        domWriter.write(source, domOutput);
        subscrXML = domOutput.getCharacterStream().toString();
        DOMStringList dsl=domConfig.getParameterNames();
        System.out.println(subscrXML);
        /*
         // Just for curiosity.... 
         for(int i=0;i<dsl.getLength();i){
            System.out.println(dsl.item(i)" = ["domConfig.getParameter(dsl.item(i))"]");
        }*/
     } catch (Exception e) {
         e.printStackTrace();
     }
    return subscrXML;
 }
