socket 发送和接收XML 并解析_socket发送xml-优快云博客

本文链接：https://blog.youkuaiyun.com/shaird/article/details/183670

本文展示了如何使用Java的Socket编程发送XML文件到服务器，并在服务器端接收XML内容，然后进行解析。客户端通过Socket连接本地服务器，读取XML文件逐行发送，服务器端接收到数据后写入文件，并使用SAX解析器解析XML。

就是在用JAVA获取XML信息第二步(SAX) 上面增加一点内容。用Socket发送和接收。

客户端口：XMLC.java

public class XMLClient {
static Socket sock;

    public static void main(String[] args)throws Exception{
    sock = new Socket(InetAddress.getLocalHost(),8210);

    PrintWriter write = new PrintWriter(new OutputStreamWriter (sock.getOutputStream()),true);
    File file = new File("../shaird/xmldata/peopel.xml"); //用于发送的文件路径
    BufferedReader read = new BufferedReader(new FileReader(file));

    String str=null;
    while((str = read.readLine()) != null)
    write.println(str);
    write.flush();
    s.close();
    }

}

服务端口： XMLS.java

import java.io.*;
import java.net.*;
import org.xml.sax.*;
import org.xml.sax.helpers.XMLReaderFactory;

/**

*/
public class XMLServer {
    public static void main(String[] args) throws IOException,SAXException{
    String URL="../shaird/xmldata/book.xml";
    //通过指定解析器的名称来动态加载解析器
    XMLReader reader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");

    //处理内容前要注册内容管理器
    reader.setContentHandler(new XMLHandler());

    ServerSocket server=new ServerSocket(8210);
    Socket client=server.accept();
    BufferedReader br=new BufferedReader(new InputStreamReader(client.getInputStream()));
    PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(URL,false)));
    String str=null;
    String xml=new String();
    while((str = br.readLine()) != null){
        xml+=str+"/n";
        out.println(str);
    }
    out.flush();
    System.out.println(xml);

    InputSource inputSource= new InputSource(xml);
    inputSource.setSystemId(URL);
    reader.parse(inputSource);
    client.close();

    File f = new File(URL);
    f.delete();

}

好了和之前的用JAVA获取XML信息第二步(SAX) 里面的内容XMLhandler.java联合用用看。
