一、客戶端以XML格式向服務器端發送數據,并解析XML輸出到控制臺

要求如下：

客戶端以XML格式向服務器端發送數據，詳細要求如下：

1）客戶端讀取myemp.xml數據，將其發送到服務器端。

2）服務器接收到XML格式的數據后，進行解析，將解析到的數據輸出到控制臺。

代碼如下：Emp類

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;} }客戶端：

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; /*** 客戶端*/ public class Client {private Socket socket;public Client() throws UnknownHostException, IOException{socket = new Socket("192.168.1.100",8088);}public void start(){try {//獲取輸出流OutputStream out = socket.getOutputStream();File file = new File("./src/day08/myemp.xml");//創建SAXReader,讀取指定文件SAXReader reader = new SAXReader();Document doc = reader.read(file);//創建XML輸出流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("客戶端初始化失敗");} } }服務端：

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;/*** 服務端*/ public class Server {private ServerSocket server;public Server() throws IOException{server = new ServerSocket(8088);}public void start(){try {//監聽客戶端,建立連接System.out.println("等待連接..........");Socket socket = server.accept();System.out.println("服務端連接成功!");//獲取輸入流InputStream in = socket.getInputStream();//創建SAXReader,讀取指定文件SAXReader reader = new SAXReader();Document doc = reader.read(in);//獲取根節點Element root = doc.getRootElement();//獲取根節點(list)下所有子節點empList<Element> list = root.elements();//保存所有員工對象的集合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("解析完畢!");//輸出到控制臺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("初始化服務端失敗!");}} }測試結果會在服務端輸出：

等待連接.......... 服務端連接成功! 解析完畢! 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

二、客戶端以XML格式向服務器端發送數據

要求如下：

客戶端以XML格式向服務器端發送數據，詳細要求如下：

1）客戶端讀取myemp.xml中的數據，將其發送到服務器端。

2）服務器接收到XML格式的數據后，將其輸出到serverMyemp.xml文件中。

代碼如下:

客戶端：

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;public class Client {private Socket socket;public Client() throws UnknownHostException, IOException{socket = new Socket("192.168.1.100",8088);}public void start(){try{OutputStream out = socket.getOutputStream();//創建SAXReader,讀取指定文件SAXReader reader = new SAXReader();File file = new File("myemp.xml");Document doc = reader.read(file);//創建XML輸出流XMLWriter writer = new XMLWriter();writer.setOutputStream(out);writer.write(doc);} catch(Exception e){e.printStackTrace();} finally {//只關socketif(socket != null){try {socket.close();} catch (IOException e) {e.printStackTrace();}}}}public static void main(String[] args) {Client c;try {c = new Client();c.start();} catch (Exception e) {e.printStackTrace();System.out.println("客戶端初始化失敗!");} } }服務端

代碼如下：

import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.net.ServerSocket; import java.net.Socket; import org.dom4j.Document; import org.dom4j.io.SAXReader; import org.dom4j.io.XMLWriter;public class Server {private ServerSocket server;public Server() throws IOException{server = new ServerSocket(8088);}public void start(){XMLWriter writer = null;try{System.out.println("等待連接......");Socket socket = server.accept();System.out.println("連接客戶端成功!");InputStream in = socket.getInputStream();//讀取用戶發送過來的xmlSAXReader reader = new SAXReader();Document doc = reader.read(in);//寫出xml到day08包中FileOutputStream fos = new FileOutputStream("./src/day09/serverMyemp.xml");writer = new XMLWriter();writer.setOutputStream(fos);writer.write(doc);System.out.println("服務端接受文件成功!");} catch(Exception e){e.printStackTrace();} finally {//writer和server都要關if(writer != null){try {writer.close();} catch (IOException e) {e.printStackTrace();}}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("服務端初始化失敗!");}} }
服務端測試結果如下：

等待連接...... 連接客戶端成功! 服務端接受文件成功!
