使用dom4j 将xml文件中的数据导入到数据库中

什么是dom4j:它就是java的一个xml api，用来读写XML文件的。

第一步：用eclipse创建一个简单的java project

             

第二步：导入所需要的包，这里导入到的是mysql数据库

             dom4j-1.6.1 (1).jar
             jaxen-1.1-beta-6.jar

             mysql-connector-java-5.1.41-bin.jar

           所需要包的地址点击打开链接

第三步：编写DBUtil.java 连接数据库

            

public class DBUtil {

    private static final String URL="jdbc:mysql://127.0.0.1:3306/xmlinto?useUnicode=true&characterEncoding=utf-8";
    private static final String USER="root";
    private static final String PASSWORD="123456";
    
    private static Connection conn=null;
    
    static {
        try {
            //1.加载驱动程序
            Class.forName("com.mysql.jdbc.Driver");
            //2.获得数据库的连接
            conn=DriverManager.getConnection(URL, USER, PASSWORD);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
    //将获得的数据库与java的链接返回（返回的类型为Connection）
    public static Connection getConnection(){
        return conn;
    }
	public static void close(PreparedStatement pstmt) {
		// TODO Auto-generated method stub
		
	}
	public static void close(Connection conn2) {
		// TODO Auto-generated method stub
		
	}
}

第四步：编写xml文件

                S7  
              
          
      
  

第五步：编写TestXMLImport.java

public class TestXMLImport {  
	  
    public static void main(String[] args) {  
        String sql="insert into T_XML(NUMERO, REPOSICION, NOMBRE, TURNOS) values (?, ?, ?, ?)";   
        Connection conn = null;  
        PreparedStatement pstmt = null;  
        try {  
            conn = DBUtil.getConnection();  
            pstmt = conn.prepareStatement(sql);  
            //读取xml文件，按路径读取,获得document对象  
            Document doc = new SAXReader().read(new File("D://xml/T_XML.xml"));  
            //选择xml文件的节点   
            List itemList = doc.selectNodes("/ACCESOS/item/SOCIO");  
            //遍历读出的xml中的节点   
            for(Iterator iter = itemList.iterator(); iter.hasNext();){  
                Element el = (Element)iter.next();  
                //读取节点的内容并赋值  
                String numero = el.elementText("NUMERO");  
                String reposicion = el.elementText("REPOSICION");  
                String nombre = el.elementText("NOMBRE");  
                //遍历TURNOS节点中的内容  
                List turnosList = el.elements("TURNOS");  
                StringBuffer sbString = new StringBuffer();  
                for (Iterator iterator = turnosList.iterator(); iterator  
                        .hasNext();) {  
                    Element turnosElt = (Element) iterator.next();  
                    String lu = turnosElt.elementText("LU");    
                    String ma = turnosElt.elementText("MA");    
                    String mi = turnosElt.elementText("MI");    
                    String ju = turnosElt.elementText("JU");    
                    String vi = turnosElt.elementText("VI");    
                    String sa = turnosElt.elementText("SA");    
                    String doo = turnosElt.elementText("DO");
                    sbString.append(lu + "," + ma + "," + mi + "," + ju + "," + vi + "," + sa + "," + doo);               
                }  
                //为sql语句赋值    
                pstmt.setString(1, numero);    
                pstmt.setString(2, reposicion);    
                pstmt.setString(3, nombre);    
                pstmt.setString(4, sbString.toString());    
                pstmt.addBatch();   
            }  
            //批量执行sql语句  
            pstmt.executeBatch();    
            System.out.print("将XML导入数据库成功");              
        } catch (Exception e) {  
            e.printStackTrace();  
        }finally{    
            DBUtil.close(pstmt);    
            DBUtil.close(conn);    
        }    
    }  
}
