How to fill out spring mvc command beans

How to fill out spring mvc command beans:

1. First, create a command bean class that represents the data you want to bind to the form. This class should have private fields with corresponding getter and setter methods.
2. Annotate the command bean class with the @ModelAttribute annotation to indicate that it is a form-backing bean in Spring MVC.
3. In the Spring MVC controller, create a handler method for the form submission. This method should have a parameter annotated with the @ModelAttribute annotation and the name of the command bean class as the value. This parameter will automatically be populated with the form data when the form is submitted.
4. In the JSP view, use the form tag to create the form. The commandName attribute of the form tag should be set to the name of the command bean class.
5. Inside the form, use the form tag's input fields to bind the form data to the command bean's fields. The input fields should have the name attributes set to the corresponding field names of the command bean class.
6. Finally, submit the form and handle the form submission in the Spring MVC controller's handler method. The handler method can perform any necessary validation and processing on the submitted form data.
