Problem
I developed a chat application with
Spring MVC, where I can submit messages along with my username, and those messages will be visible to any user that navigates to the /chat URL.But when I submit my message, the message is not removed from the Message Text input so I have to remove it manually.
And here is the code in
ChatController Class:
What’s wrong
when we initialize our application,
Spring will scan our project and instantiate only one ChatForm object and it will include it in the Application Context, so every time we access the chat.html page, the same instance of the ChatForm will be passed and will be used to transport the form data present in the chat.html page to the addChat method.This reuse of the same instance of the
ChatForm is done precisely so that unnecessary instances of it are created and thus end up increasing the memory consumption of our application and affect its performance.Solution
Add controller code that sets the Message Text of the
ChatForm object to "";
