问题描述

使用 com.sun.org.apache.xml.internal.serialize.XMLSerializer 和 com.sun.org.apache.xml.internal.serialize.OutputFormat 会导致使用 java 1.6 编译时出现一些错误.我找到的解决方案是在添加 xerces 后使用 org.apache.xml.serialize.XMLSerializer 和 org.apache.xml.serialize.OutputFormat .问题是这些类已被弃用.我可以在不接触代码的情况下使用什么来替换它们?谢谢这是我使用的依赖项:

Using com.sun.org.apache.xml.internal.serialize.XMLSerializer and com.sun.org.apache.xml.internal.serialize.OutputFormat causes some errors when compiling using java 1.6. The solution I found is by using org.apache.xml.serialize.XMLSerializer and org.apache.xml.serialize.OutputFormat after adding xerces. The problem is that theses classes are deprecated. What can I use without to replace them without touching the code ? Thnx This is the dependency I used :

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

推荐答案

我们可以使用 org.w3c.dom.ls 包中的 LSSerializer 类

We can use the LSSerializer class from the package org.w3c.dom.ls

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("
");     
        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;
 }
