i have a Employee class with the following content:
public class Employee {
@NotNull(message="Field Cannot be Empty")
private String epfno;
@NotNull(message="Field Cannot be Empty")
private String empno;
@NotNull(message="Field Cannot be Empty")
private String empfullname;
@NotNull(message="Field Cannot be Empty")
private Address address;
****GETTERS AND SETTERS****
}
Address class class with the following content:
public class Address {
private int addressid;
private Employee employee;
@NotNull(message="Field Cannot be Empty")
private String description;
****Getters and SETTERS****
}
具有以下内容的控制器类：当我尝试验证地址字段时，表单实际返回null . 而不是抛出一个非null错误消息 . 我在控制器中进行了调试以捕获它@RequestMapping（value =“/ Form / Employee / Submit”，method = RequestMethod.POST）public String SubmitEmployeeForm（@Valid @ModelAttribute（“Employee”）Employee Employee，BindingResult br）{
if(br.hasErrors())
{
logger.info("Form Validation Errors have Occured");
return "Homepage";
}
else {
// Does not through error instead sends null when field is empty
System.out.println(Employee.getAddress().getDescription()); // Null
return "Homepage";
}
}
How can i get the address field to get populated with a not null error message instead of it passing the value null ? thanks
