折腾了一上午，终于换一种方式搞定了。
上面这种dom4j方式，在我本机环境（windows+weblogic10+jdk1.6）下没问题，
放到服务器上（linux5.4 x64+weblogic10+jdk1.6）上，始终都报这个错：

在weblogic.xml加配置文件、加lib包等等都不起作用，换成这个就好了（依赖lib在我上传的资源中，完全免费）：
try { url url = new url(rss); // 读取rss源 xmlreader reader = new xmlreader(url); system.out.println("rss源的编码格式为：" + reader.getencoding()); syndfeedinput input = new syndfeedinput(); syndfeed feed = input.build(reader); // 得到syndfeed对象，即得到rss源里的所有信息 list entries = feed.getentries(); // 得到rss新闻中子项列表 int index =0; for (int i = 0; i < entries.size(); i++) { // 循环得到每个子项信息 if(index+1>rsstable.rows.length){ break; } syndentry entry = (syndentry) entries.get(i); /* system.out.println("标题：" + entry.gettitle()); system.out.println("连接地址：" + entry.getlink()); syndcontent description = entry.getdescription(); system.out.println("标题简介：" + description.getvalue()); system.out.println("发布时间：" + entry.getpublisheddate()); // 以下是rss源可先的几个部分 system.out.println("标题的作者：" + entry.getauthor()); */ ci.adp.datarow rssrow = rsstable.getdatarowbyindex(index); rssrow.setvalue("title", entry.gettitle()); rssrow.setvalue("link", entry.getlink()); rssrow.setvalue("pubdate", entry.getpublisheddate()); rssrow.setvalue("source", entry.getauthor()); /* // 此标题所属的范畴 list categorylist = entry.getcategories(); if (categorylist != null) { for (int m = 0; m < categorylist.size(); m++) { syndcategory category = (syndcategory) categorylist .get(m); system.out.println("此标题所属的范畴：" + category.getname()); } } */ index++; /* // 得到流媒体播放文件的信息列表 list enclosurelist = entry.getenclosures(); if (enclosurelist != null) { for (int n = 0; n < enclosurelist.size(); n++) { syndenclosure enclosure = (syndenclosure) enclosurelist .get(n); system.out.println("流媒体播放文件：" + entry.getenclosures()); } } */ } } catch (exception e) { e.printstacktrace(); }
org.dom4j.io.saxreader saxreader = new org.dom4j.io.saxreader();org.dom4j.document document = saxreader.read(rssurl);org.dom4j.element channel = (org.dom4j.element) document.getrootelement().element("channel"); int index =0; for (java.util.iterator i = channel.elementiterator("item"); i.hasnext();){ if(index+1>rsstable.rows.length){ break; } org.dom4j.element element = (org.dom4j.element) i.next(); string title = element.elementtext("title"); string link = element.elementtext("link"); string pubdate = element.elementtext("pubdate"); string source = element.elementtext("source"); ci.adp.datarow rssrow = rsstable.getdatarowbyindex(index); rssrow.setvalue("title", title); rssrow.setvalue("link", link); rssrow.setvalue("pubdate", pubdate); rssrow.setvalue("source", source); /* system.out.println("title标题: " + title); system.out.println("link链接: " + link); system.out.println("pubdate发布时间: " +pubdate); system.out.println("source来源: " + source); */ index++; }
以上就是解析rss问题的总结的详细内容。
