將應用程式部署到 Liberty
-
在命令列上部署一個簡單的應用程式
- 建立一個簡單的 servlet:
package web.example;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@WebServlet("/*")
public class HelloServlet extends HttpServlet
{
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException
{
response.getWriter().println("Hello world!");
}
}
- 將應用程式打包到 Web 存檔(.war)中:
helloapp.war
+- META-INF\
+- WEB-INF\
+- web\example\HelloServlet.class
- 將應用程式新增到 Liberty 伺服器:
$> mv helloapp.war $WLP_INSTALL_DIR/usr/servers/myServer/apps/
- 配置 server.xml 以瞭解應用程式並啟用 Servlet 3.1 技術:
$> cat $WLP_INSTALL_DIR/usr/servers/myServer/server.xml
<server>
<featureManager>
<feature>servlet-3.1</feature>
</featureManager>
<application location="helloapp.war"/>
</server>
- 啟動伺服器:
$> server start myServer
Starting server myServer
Server myServer started with process ID 1234.
- 檢查 console.log 以驗證應用程式是否已啟動,以及在以下位置找到它的 URL:
$> tail $WLP_INSTALL_DIR/usr/servers/myServer/logs/console.log
...
[AUDIT ] CWWKT0016I: Web application available (default_host): http://localhost:9080/helloapp/
[AUDIT ] CWWKZ0001I: Application helloapp started in 0.272 seconds.
- 在 Web 瀏覽器中,按照 console.log 中的說明轉到 URL
http://localhost:9080/helloapp/
。你應該看到來自 servlet 的訊息:
Hello world!
