The full specifications of classes, interfaces, and method signatures that define the Java Servlet API, as well as their accompanying Javadoc™documentation, is available online.
Servlet container calls servlet init() method before handling client requests. It is called just one times after servlet is created. By default it does nothing. You can override this method and it is also good for performing one-time activities.
19 paź 2021 · init() method: The Servlet.init() method is called by the Servlet container to indicate that this Servlet instance is instantiated successfully and is about to put into service.
The init ( ) method is typically used to perform servlet initialization creating or loading objects that are used by the servlet in the handling of its requests. During the init ( ) method a servlet may want to read its initialization (init) parameters. These parameters are given to the servlet itself and are not associated with any single request.
Called by the servlet container to indicate to a servlet that the servlet is being placed into service. The servlet container calls the init method exactly once after instantiating the servlet. The init method must complete successfully before the servlet can receive any requests.
This interface defines the init() method to match the initialization phase of a Servlet life cycle. When a container loads a Servlet, it invokes the init() method before servicing any requests. The service phase of the Servlet life cycle represents all interactions with requests until the Servlet is destroyed.
base class for all servlets, the Servlet interface defines five methods. The three most important of these methods and their functions are the init() method, which initializes a servlet; the service() method, which services client requests; and the destroy method, which performs cleanup. These methods make up the servlet lifecycle methods.
