Whats the difference b/w request scope vs prototype scope in terms of a webapplication..where there are 2 beans
1 is request scope
1 is prototype bean...
And both end up being used for the processing...
For x request...x request beans & x prototype beans are created ..so what is the difference between the two..
Regards
Prototype creates a brand new instance everytime you call getBean on the ApplicationContext. Whereas for Request, only one instance is created for an HttpRequest. So in a single HttpRequest, I can call getBean twice on Application and there will ever be one bean instantiated, whereas that same bean scoped to Prototype in that same single HttpRequest would get 2 different instances.
HttpRequest scope
Mark mark1 = context.getBean("mark");
Mark mark2 = context.getBean("mark");
mark1 == mark2; //This will return true
Prototype scope
Mark mark1 = context.getBean("mark");
Mark mark2 = context.getBean("mark");
mark1 == mark2; //This will return false
Hope that clears it up for you.
