What is the doGet method in a Servlet, and when is it called?

Question

Aryan Kumar · Answer

In a servlet, the doGet method is a part of the HTTP servlet's life cycle and is designed to handle HTTP GET requests. The doGet method is automatically called by the servlet container when a client sends an HTTP GET request to the servlet. It's one of the key methods for processing client requests in a servlet. Let's break down its purpose and usage: Method Signature: The doGet method is defined in the HttpServlet class and is overridden in your servlet class. Handling GET Parameters: Use the HttpServletRequest object to access parameters sent in the URL or as part of the query string in a GET request. Processing the Request: Perform any necessary processing based on the information in the request. This could include retrieving data from a database, generating dynamic content, or any other business logic. Automatic Invocation: The doGet method is automatically invoked by the servlet container when a client makes an HTTP GET request to the servlet's URL. Configuring URL Mapping: In the web.xml file or using annotations, you need to configure the servlet to handle specific URL patterns. This tells the servlet container when to call the doGet method. In summary, the doGet method in a servlet is responsible for handling HTTP GET requests. It processes incoming requests, accesses parameters, performs necessary business logic, and sends an appropriate response back to the client. The servlet container automatically calls this method when a client sends an HTTP GET request to the servlet's specified URL pattern.
