客户端以XML格式向服务器端发送数据，详细要求如下：
1）客户端读取myemp.xml数据，将其发送到服务器端。
2）服务器接收到XML格式的数据后，进行解析，将解析到的数据输出到控制台。
代码如下：Emp类 public class Emp { private int id; private String name; private int age; private String gender; private int salary; public Emp(int id, String name, int age, String gender, int salary) { super(); this.id = id; this.name = name; this.age = age; this.gender = gender; this.salary = salary; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } public int getSalary() { return salary; } public void setSalary(int salary) { this.salary = salary; } public String toString(){ return id+","+name+","+age+","+gender+","+salary; } }客户端： import java.io.File; import java.io.IOException; import java.io.OutputStream; import java.net.Socket; import java.net.UnknownHostException; import org.dom4j.Document; import org.dom4j.io.SAXReader; import org.dom4j.io.XMLWriter; /** * 客户端 */ public class Client { private Socket socket; public Client() throws UnknownHostException, IOException{ socket = new Socket("192.168.1.100",8088); } public void start(){ try { //获取输出流 OutputStream out = socket.getOutputStream(); File file = new File("./src/day08/myemp.xml"); //创建SAXReader,读取指定文件 SAXReader reader = new SAXReader(); Document doc = reader.read(file); //创建XML输出流 XMLWriter writer = new XMLWriter(); writer.setOutputStream(out); writer.write(doc); } catch (Exception e) { e.printStackTrace(); } finally { if(socket != null){ try { socket.close(); } catch (IOException e) { e.printStackTrace(); } } } } public static void main(String[] args) { try { Client c = new Client(); c.start(); } catch (Exception e) { e.printStackTrace(); System.out.println("客户端初始化失败"); } } }服务端： import java.io.IOException; import java.io.InputStream; import java.net.ServerSocket; import java.net.Socket; import java.util.ArrayList; import java.util.List; import org.dom4j.Document; import org.dom4j.Element; import org.dom4j.io.SAXReader; /** * 服务端 */ public class Server { private ServerSocket server; public Server() throws IOException{ server = new ServerSocket(8088); } public void start(){ try { //监听客户端,建立连接 System.out.println("等待连接.........."); Socket socket = server.accept(); System.out.println("服务端连接成功!"); //获取输入流 InputStream in = socket.getInputStream(); //创建SAXReader,读取指定文件 SAXReader reader = new SAXReader(); Document doc = reader.read(in); //获取根节点 Element root = doc.getRootElement(); //获取根节点(list)下所有子节点emp List<Element> list = root.elements(); //保存所有员工对象的集合 List<Emp> emplist = new ArrayList<Emp>(); for(Element e : list){ int id = Integer.parseInt(e.attribute("id").getValue()); String name = e.elementText("name"); int age = Integer.parseInt(e.elementText("age")); String gender = e.elementText("gender"); int salary = Integer.parseInt(e.elementText("salary")); emplist.add(new Emp(id,name,age,gender,salary)); } System.out.println("解析完毕!"); //输出到控制台 for(Emp e : emplist){ System.out.println(e); } } catch (Exception e) { e.printStackTrace(); } finally { if(server != null){ try { server.close(); } catch (IOException e) { e.printStackTrace(); } } } } public static void main(String[] args) { try { Server s = new Server(); s.start(); } catch (IOException e) { e.printStackTrace(); System.out.println("初始化服务端失败!"); } } }测试结果会在服务端输出： 等待连接.......... 服务端连接成功! 解析完毕! 1,jack,33,男,5000 2,boss,55,男,5500 3,marry,22,女,3500 4,kate,25,女,6000 5,tom,31,男,8500客户端以XML格式向服务器端发送数据，详细要求如下：
1）客户端读取myemp.xml中的数据，将其发送到服务器端。
2）服务器接收到XML格式的数据后，将其输出到serverMyemp.xml文件中。
代码如下:客户端：
