建立 Maven 專案
使用下列 Maven 原型命令，為您的 JAVA Web 應用程式建立 Maven 專案：
mvn archetype:generate \
-DgroupId=com.microsoft.azure.samples \
-DartifactId=azure-javaweb-app-simple \
-DarchetypeArtifactId=maven-archetype-quickstart \
-Dversion=1.0-SNAPSHOT \
-DinteractiveMode=false
您應該會看見下列輸出：
[INFO] ----------------------------------------------------------------------------
[INFO] Parameter: basedir, Value: /home/ayangupta/LearnProjects/DeployHelloApp
[INFO] Parameter: package, Value: com.microsoft.azure.samples
[INFO] Parameter: groupId, Value: com.microsoft.azure.samples

[INFO] Parameter: packageName, Value: com.microsoft.azure.samples
[INFO] Parameter: version, Value: 1.0-SNAPSHOT

現可使用下列檔案及目錄：
└── azure-javaweb-app-simple
├── src
│ ├── main
│ │ └── java
│ │ └── com
│ │ └── microsoft
│ │ └── azure
│ │ └── samples
│ │ └── App.java
│ └── test
│ └── java
│ └── com
│ └── microsoft
│ └── azure
│ └── samples
│ └── AppTest.java
└── pom.xml
修改 Maven pom.xml 檔案
以下列程式代碼取代 pom.xml 的內容。 此更新 pom.xml 帶來此 Web 應用程式所需相依性的正確版本。

建立主應用程式類別
編輯 src/main/java/com/microsoft/azure/samples 目錄中的App.java檔案，以使用下列程式代碼來建立簡單的 HTTP 伺服器：
package com.microsoft.azure.samples;
import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpServer;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpExchange;
public class App {
public static void main(String[] args) throws IOException {
HttpServer server = HttpServer.create(new InetSocketAddress(8080), 0);
server.createContext("/", new HelloHandler());
server.setExecutor(null); // creates a default executor
server.start();
System.out.println("Server started on http://localhost:8080/");
}
static class HelloHandler implements HttpHandler {
@Override
public void handle(HttpExchange exchange) throws IOException {
String response = "Hello, World!";
exchange.sendResponseHeaders(200, response.length());
OutputStream os = exchange.getResponseBody();
os.write(response.getBytes());
os.close();
}
}
}
