How to get getServletContext() in spring mvc Controller

In a Spring MVC controller, you can access the ServletContext using the HttpServletRequest object. The HttpServletRequest provides a method called getServletContext() that allows you to obtain a reference to the ServletContext. Here's how you can do it:

import javax.servlet.ServletContext; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller public class MyController { @RequestMapping(value = "/example", method = RequestMethod.GET) public String example(HttpServletRequest request) { // Get the ServletContext ServletContext servletContext = request.getServletContext(); // Now you can use the ServletContext as needed String contextPath = servletContext.getContextPath(); // ... return "exampleView"; } }

In the example above:

  1. We inject the HttpServletRequest object as a parameter of the controller method example.

  2. Within the example method, we call request.getServletContext() to obtain a reference to the ServletContext.

  3. You can now use the ServletContext object to access attributes, resources, or perform other operations related to the servlet context.

Make sure that you have the necessary Spring dependencies and configuration in your project to use Spring MVC controllers. Additionally, ensure that the URL mapping (e.g., /example in this case) corresponds to your actual mapping configuration.
