其实是三个知识点综合到一起的，包括如何访问mysql，如何生成xml文件，如何使用进行webservice开发

好了，话不多说，直接粘代码

package com.service;import java.io.FileOutputStream;import java.io.IOException;import java.sql.*;import org.jdom.*;import org.jdom.output.XMLOutputter;public class NewsImpl implements NewsInterface{		public String GetNews(int StartPage, int EndPage) 	{		// 创建根节点 list;	Element root = new Element("xyt");		 // 根节点添加到文档中；	Document Doc = new Document(root);	 	Connection conn = null;	Statement stmt = null ;	 // 此处 for 循环可替换成 遍历 数据库表的结果集操作;	try {			Class.forName("org.gjt.mm.mysql.Driver").newInstance();			 String url_connect ="jdbc:mysql://localhost/nxu_life?user=root&password=12345&useUnicode=true&characterEncoding=gb2312";		//first为你的数据库名			 	try {					conn = DriverManager.getConnection(url_connect);				} catch (SQLException e0) {					// TODO Auto-generated catch block					e0.printStackTrace();				}						try {					stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);				} catch (SQLException e00) {					// TODO Auto-generated catch block					e00.printStackTrace();				}		String sql="select page_id,title,url,publishtime,page,department from news where page_id>="+StartPage+" and page_id<="+EndPage;		try {					ResultSet rs=stmt.executeQuery(sql);					 while(rs.next()){						 String page_id=rs.getString("page_id");						 String title=rs.getString("title");						 String url=rs.getString("url");						 String publishtime=rs.getString("publishtime");						 String page=rs.getString("page");						 String department=rs.getString("department");				 // 创建节点 user;				 Element elements = new Element("news");				 // 给 user 节点添加属性 id;				 elements.setAttribute("id",page_id);								 // 给 user 节点添加子节点并赋值；				 // new Element("name")中的 "name" 替换成表中相应字段，setText("xuehui")中 "xuehui 替换成表中记录值；				 elements.addContent(new Element("url").setText(url));				 elements.addContent(new Element("title").setText(title));				 elements.addContent(new Element("publishtime").setText(publishtime));				 elements.addContent(new Element("page").setText(page));				 elements.addContent(new Element("department").setText(department));				 // 给父节点list添加user子节点;				 root.addContent(elements);				 				 }				} catch (SQLException e) {					// TODO Auto-generated catch block					e.printStackTrace();				}		} catch (InstantiationException e1) {			// TODO Auto-generated catch block			e1.printStackTrace();		} catch (IllegalAccessException e2) {			// TODO Auto-generated catch block			e2.printStackTrace();		} catch (ClassNotFoundException e3) {			// TODO Auto-generated catch block			e3.printStackTrace();		}	 	 	XMLOutputter XMLOut = new XMLOutputter();	String XMLString =XMLOut.outputString(Doc);	return XMLString;	//System.out.println( XMLString);}}
