I'm very new in Java. So if I'm saying something nonsense then please suggest the correct way.
I'm trying to use spring MVC form validation using Java bean API validation. Seems I'm getting the error message in my controller. But, I need some model attribute to send to view along with the validation message and here I'm unable to pass it correctly. Please suggest me the correct way to do it.
Display Controller:
@RequestMapping(value = "/admin/student")
public String student(Model model) throws ParseException {
model.addAttribute("student", new Student());
model.addAttribute("studentlist", this.studentService.getAll());
model.addAttribute("statelist", this.stateService.getAll());
model.addAttribute("courselist", this.courseService.getAllForDropDown());
return "manage-student";
}Form Submit Controller:
/**
* Adds or updates a student.
*/
@RequestMapping(value = {"/data-entry/student/add", "/data-entry/student/add/"}, method = RequestMethod.POST)
public String addStudent(@Valid @ModelAttribute("student") Student s, BindingResult result, Map<String, Object> model) {
if( ! result.hasErrors() ) {
if( s.getId() == 0 ) {
this.studentService.add(s);
} else {
this.studentService.update(s);
}
return "redirect:/admin/student";
} else {
return "forward:/admin/student";
}
}JSP view:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

May be my question is similar to this post. But, here in my post the display and form processing controllers are different and these two controllers handle multiple URLs. I found difficult to apply the same solution in my case.
