I have Spring form in index.jsp:
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<html>
<body>
<form:form action="save" name="employeeDTO" method="POST">
<label for="name">Name</label><input id="name" type="text" required><br>
<label for="surname">Surname</label><input id="surname" type="text" required><br>
<label for="email">E-mail</label><input id="email" type="email" required><br>
<label for="salary">Salary</label><input id="salary" type="number" required><br>
<input type="submit" value="Save">
</form:form>
</body>
</html>
In WorkController.java I try to map form submit (at this moment, it doesn't do anything with data):
@Controller
public class WorkController {
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@RequestParam EmployeeDTO employeeDTO){
return "saved";
}
}
But I got HTTP 400 Status: Required EmployeeDTO parameter 'employeeDTO' is not present with description: The request sent by the client was syntactically incorrect.
There is EmployeeDTO.java:
public class EmployeeDTO implements Serializable, DTO {
private Long id;
private String name;
private String surname;
private String email;
private Double salary;
public EmployeeDTO(){}
public EmployeeDTO(Long id, String name, String surname, String email, Double salary){
this.id = id;
this.name = name;
this.surname = surname;
this.email = email;
this.salary = salary;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSurname() {
return surname;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Double getSalary() {
return salary;
}
public void setSalary(Double salary) {
this.salary = salary;
}
@Override
public Serializable toEntity() {
return new Employee(getId(), getName(), getSurname(), getEmail(), getSalary());
}
}
If I remove @RequestParam EmployeeDTO employeeDTO from save method signature - it works, it redirects to saved.jsp file. Earlier, I uses @RequestParam String name, @RequestParam String surname etc to catch data from HTML forms. Is there any solution to "catch" data from Spring form as DTO object? I wolud be happy if anbyody decides to help me - thank you in advance.

You may try with @ModelAttribute (Visit ModelAttribute question in SO to get clear understanding about it)
@RequestMapping(value = "/save", method = RequestMethod.POST)
public String save(@ModelAttribute("employeeDTO") EmployeeDTO employeeDTO){
return "saved";
}
I used this in spring mvc 3.1
