I'm setting up a spring project, I want to make user registration functionality. I want to submit user data to spring controller and receive data by a @ModelAttribute
, But ModelAttribute
returns some values properly but some doesn't.
this is my user bean.
public class User {
private Long id;
private String userName;
private String password;
private String email;
private Date regdate;
private String loginId;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUsername() {
return userName;
}
public void setUsername(String username) {
this.userName = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public Date getRegdate() {
return regdate;
}
public void setRegdate(Date regdate) {
this.regdate = regdate;
}
public String getLoginId() {
return loginId;
}
public void setLoginId(String loginId) {
this.loginId = loginId;
}
}
this is form I want to submit.
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<form action="register" method="post" modelAttribute="user">
<label for="loginid">ID:</label>
<input type="text" name="loginid">
<label for="password">password :</label>
<input type="password" name="password">
<label for="username">username :</label>
<input type="text" name="username">
<label for="email">e-mail :</label>
<input type="text" name="email">
<input type="submit" name="submit" value="submit"/>
</form>
</body>
</html>
so I printed out model attribute to log data out.
System.out.println("loginid :"+user.getLoginId()+"username :"+user.getUsername()+" password :"+ user.getPassword());
and it returned loginid :null username :user password :user
this is controller that I receive data. I tried to get a data by a ModelAttribute Annotation
@RequestMapping(value="/register", method=RequestMethod.POST)
public String createUser(@ModelAttribute User user, HttpServletRequest request, Model model) {
String ip = request.getRemoteAddr().toString();
System.out.println("loginid :"+user.getLoginId()+"id :"+user.getId()+"username :"+user.getUsername()+"password :"+ user.getPassword());
try {
userService.addUser(user,ip);
return "registrationsuccess";
}catch(Exception e) {
e.printStackTrace();
}
return "registrationfail";
}
Try to look here Maybe you have not RequestMapping in your Post method?
P.S
Try to change
<form action="register" method="post" modelAttribute="user">
<label for="loginid">ID:</label>
<input type="text" name="loginid">
<label for="password">password :</label>
<input type="password" name="password">
<label for="username">username :</label>
<input type="text" name="username">
<label for="email">e-mail :</label>
<input type="text" name="email">
<input type="submit" name="submit" value="submit"/>
</form>
to
<form:form method="post" action="/register" modelAttribute="user">
<form:label path="loginid">ID:</form:label>
<form:input path="loginid" />
<form:label path="password">password:</form:label>
<form:input path="password" />
...
<input type="submit" value="submit" />
</form:form>
In your controller, try to change
public String createUser(@ModelAttribute User user, HttpServletRequest request, Model model)
to
public String createUser(@ModelAttribute("user") User user, HttpServletRequest request, Model model)
