How to handle HTTP POST requests in a Servlet?

Question

Aryan Kumar · Answer

Handling an HTTP POST request in a servlet involves implementing the doPost method. This method is called by the servlet container when the client sends an HTTP POST request. Here's a simple guide:
Override the doPost Method:
In your servlet class, override the doPost method provided by the
HttpServlet class.
Access POST Parameters:
Use the HttpServletRequest object to access parameters sent in the POST request. This could be form data, JSON, XML, or any other payload.
Read Request Body (Optional):
If you're dealing with more complex data like JSON or XML, you might need to read the request body directly.
Set Response (If Applicable):
If your servlet needs to send a response back to the client, use the 
HttpServletResponse object.
Remember to configure your servlet in the web.xml file or use annotations, specifying the URL pattern that this servlet should handle.
andlt;servlet>
    andlt;servlet-name>MyServletandlt;/servlet-name>
    andlt;servlet-class>com.example.MyServletandlt;/servlet-cla
Or using annotations:
@WebServlet("/myServlet")
public class MyServlet extends HttpServlet {
    // ...
}
This sets up your servlet to handle HTTP POST requests at the specified URL pattern ("/myServlet" in this example). Adjust the URL pattern according to your application's needs.
