Freemarker and Spring Validation Error Message Doesn't show up error messages - spring

Question

Hi I am working on spring boot 1.5.9.RELEASE and added spring-webmvc (4.3.13.RELEASE) dependency.
When I hit the submit button with some form data, it goes to server and checks if there're some errors, and prints it on console, and return back to form input page. but there is no error messages printed.
I submit the form with ModelAttribute object and the object is defined like below:
#Entity
#Table(name="MEMBER", uniqueConstraints={
#UniqueConstraint(columnNames={"USER_SEQ"}),
#UniqueConstraint(columnNames={"USER_EMAIL"}),
#UniqueConstraint(columnNames={"NICKNAME"})
})
#Data
#NoArgsConstructor
#RequiredArgsConstructor(staticName="of")
public class Member implements Serializable{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name="USER_SEQ", unique=true, nullable=false)
private Long userSeq;
#Email
#NotNull
#NonNull
#Column(name="USER_EMAIL", unique=true, nullable=false, length=50)
private String userEmail;
#NotNull
#NonNull
#Column(name="USER_PW", nullable=false, length=255)
private String userPw;
#NotNull
#Size(min=2, max=10)
#NonNull
#Column(name="NICKNAME", unique=true, nullable=false, length=20)
private String nickname;
#OneToOne(mappedBy="member", cascade=CascadeType.ALL)
private MemberSecurity security;
#Override
public String toString() {
return "Member [userSeq=" + userSeq + ", userEmail=" + userEmail + ", userPw=" + userPw + ", nickname="
+ nickname + "]";
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
Member other = (Member) obj;
if (userSeq == null) {
if (other.userSeq != null)
return false;
} else if (!userSeq.equals(other.userSeq))
return false;
return true;
}
#Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result + ((userSeq == null) ? 0 : userSeq.hashCode());
return result;
}
}
In Controller which the submit goes through, I coded like below:
#RequestMapping(value="/join", method=RequestMethod.POST)
public String join(Model model, #Valid #ModelAttribute("join") Member member, BindingResult bindingResult, RedirectAttributes redirect){
if(bindingResult.hasErrors()){
viewNameChooser.joinForm(model);
System.err.println("ERROR COUNT: " + bindingResult.getErrorCount());
System.err.println("ERROR FIELD: " + bindingResult.getFieldError().getField());
System.err.println("ERROR CODE: " + bindingResult.getFieldError().getCode());
return go();
}
redirect.addFlashAttribute("joinSuccess", String.valueOf(memberService.save(member)) );
return "redirect:/member/login-form";
}
and the console output is :
ERROR COUNT: 1
ERROR FIELD: nickname
ERROR CODE: Size
Now I registered my custom error messages in classpath:META-INF/messages.properties:
Email.member.userEmail=It is not email type text.
NotNull.member.userEmail=Please, type your email id.
NotNull.member.userPw=Please, type your password.
NotNull.member.nickname=Please, type your nickname.
Size.member.nickname=The length of nickname must be greater than or equal 2 and less than or equal 10.
So far so good, but in my freemarker template, there is no error message displayed. I have coded like below:
<#assign form=JspTaglibs["http://www.springframework.org/tags/form"] />
<form id="join-form" action="<#spring.url '/member/join' />" method="post" style="width:600px; margin:0 auto;">
<#spring.bind "join" />
<#-- skipped -->
<#form.errors "*" />
<#-- skipped -->
</form>
<#form.errors "*" />
should contain error messages but it's not. Where am I missing? Help me please.
EDIT: I modified my controller method.
#RequestMapping(value="/join", method=RequestMethod.POST)
public ModelAndView join(#Valid #ModelAttribute("join") Member member, BindingResult bindingResult, RedirectAttributes redirect){
if(bindingResult.hasErrors()){
//viewNameChooser.joinForm(bindingResult);
ModelAndView modelAndView = new ModelAndView("template", bindingResult.getModel());
modelAndView.addObject("viewName", "joinForm");;
System.err.println("ERROR COUNT: " + bindingResult.getErrorCount());
System.err.println("ERROR FIELD: " + bindingResult.getFieldError().getField());
System.err.println("ERROR CODE: " + bindingResult.getFieldError().getCode());
return modelAndView;
}
ModelAndView modelAndView = new ModelAndView("redirect:/member/login-form");
redirect.addFlashAttribute("joinSuccess", String.valueOf(memberService.save(member)) );
return modelAndView;
}
Now I am using ModelAndView.
