具有 IBM Websphere 依赖性的 SAXParser 实现

Question

我正在尝试从 S.O 周围的 Java 专家那里获得一些帮助。关于这个问题。我在一个长期项目中遇到了 XMLParser 的旧实现...... 在我看来这个实现是不正确的，或者可以改进.. 我想知道是否有人可以指导该怎么做，我们将不胜感激...

这是一个具有 pom.xml 依赖关系的 Maven 项目...

问题...

所以基本上有人在项目中使用了直接来自 IBM 内部 JRE 的 class SAXParser...

我怎样才能将这种安静的代码转换为不依赖于 WAS (Websphere Aplication Server) 的依赖项？

    public boolean parse(){
    boolean res = false;
    try {
        SAXParser p = new SAXParser(); // Need to replace this for better aproach
        p.setContentHandler(this); // Need to replace this for better aproach
        InputSource inputSource = new InputSource(new StringReader(source));
        if (inputSource != null){
            p.parse(inputSource); // Need to replace this for better aproach
        }
        res = true;
    } 
    catch (Exception e) {
        System.err.println("public void parse()"+e.getLocalizedMessage());
        res= false;
        e.printStackTrace();
    }
    return res;
}

迁移成功:)

    boolean res = false;
    try {
        SAXParserFactory spf = SAXParserFactory.newInstance();
        spf.setNamespaceAware(true);
        javax.xml.parsers.SAXParser saxParser = spf.newSAXParser();

        XMLReader xmlReader = saxParser.getXMLReader();
        xmlReader.setContentHandler(this);

        InputSource inputSource = new InputSource(new StringReader(source));
        if (inputSource != null){
            xmlReader.parse(inputSource);
        }
        res = true;
    } 
    catch (Exception e) {
        System.err.println("public void parse()"+e.getLocalizedMessage());
        res= false;
        e.printStackTrace();
    }
    return res;
}

您可以从 javax.xml.parsers.SAXParserFactory:

请求 javax.xml.parsers.SAXParser 而不是显式构建 SAXParser 实现

   SAXParserFactory spf = SAXParserFactory.newInstance();
   spf.setNamespaceAware(true);
   SAXParser saxParser = spf.newSAXParser();
These lines of code create a SAXParserFactory instance, as determined by the setting of the javax.xml.parsers.SAXParserFactory system property.

本文来自 the Java tutorial for Parsing an XML file using SAX.

然后可以从SAXParser获取XMLReader，设置contentHandler，从InputSource解析xml:

XMLReader xmlReader = saxParser.getXMLReader();
xmlReader.setContentHandler(new WhateverYouNameYourContentHandler());
xmlReader.parse(inputSource);
