I have the following spring mvc code snippet that works fine:
Controller snippet:
@RequestMapping(value="/submitForm", method=RequestMethod.POST)
public String formSubmission(Employee employee)
{
return "EmployeeWelcome";
}
On form data printing page:
<html>
<h4>List of Request Parameters</h4>
<h4>first name - ${employee.firstName}</h4>
<h4>last name - ${employee.lastName}</h4>
<h4>user email - ${employee.email}</h4>
<h4>user salary - ${employee.salary}</h4>
</html>
The above prints all the values successfully, then why is the following required?
ModelMap, Model, @ModelAttribute, ModelAndView
If you want to get the model value or any message to the Ui from the java side then you would need these
You can check the details here: What are the differences between Model, ModelMap, and ModelAndView?
Check the docs: https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/ModelAndView.html
