How to add an object to application scope in Spring

Question

We can set the request attributes using Model or ModelAndView object in Spring.

We can use @SessionAttributes to keep attributes

Answer 1

When you mention about storing your model at application scope then I would conclude you wish to store it at the ServletContext level. For doing that you need to make your controller implements ServletContextAware interface.

import org.springframework.web.context.ServletContextAware;

// ...

public class MyController implements ServletContextAware {

private ServletContext context; 
    public void setServletContext(ServletContext servletContext) { 
    this.context = servletContext;
     }

After getting access to ServletContext you can add it as a attribute

servletContext.setAttribute("modelKey", modelObject);

Kindly let me know if this is what you are looking for.
