Sending POST request to REST endpoint using Jquery
Question
I want to submit all fields from registration form and store them in PostgreSQL database. I'm using Spring MVC and jQuery. POST request to /save is working only using Postman. When I click on Register button to submit form it gives me -
"Request method 'POST' not supported".
Can anybody help me?
User Controller:
@RestController
public class UserController {
@Autowired
private UserService userService;
@RequestMapping(method=RequestMethod.POST, value="/save", headers="Accept=application/x-www-form-urlencoded")
public void registerUser(@RequestBody User user) {
userService.registerUser(user);
}
}
PageController:
@Controller
public class PageController {
@RequestMapping("/login")
public String login () {
return "index.html";
}
}
Model:
@Entity
@Data
@Table(name="users")
public class User {
@Id @GeneratedValue
private long id;
@Column(name="sex")
private String sex;
@Column(name="skype")
private String skype;
@Column(name="username")
private String userName;
@Column(name="email")
private String email;
@Column(name="password")
private String password;
protected User(){};
}

Instead of doing input type='submit' can you try using input type='button'
change the line data["username"] = $("#register_email").val(); to data["userName"] = $("#register_email").val(); data["username"] = $("#register_email").val(); to data["userName"] = $("#register_email").val();

You're sending application/json in your ajax call, but in your controller, you say that your endpoint only accepts application/x-www-form-urlencoded .
You can change your controller to accept application/json :
@RequestMapping(method=RequestMethod.POST, value="/save", headers="Accept=application/json")
To avoid typos, you could also use the @RequestMapping 's consumes attribute, and pass it a MediaType constant:
@RequestMapping(method=RequestMethod.POST, value="/save", consumes=MediaType.APPLICATION_JSON_VALUE)
Or you can refactor your ajax call to send the serialized form data.
As @sparrow suggests, you may also want to change your button's type attribute to button in order to avoid the default browser submit behavior. Alternatively, you can call event.preventDefault(); inside your click handler function to accomplish the same thing, but it doesn't make much sense to use type="submit" unless you're actually wanting to use the browser's default submit behavior.

好的，问题是我没有正确选择dom元素，而是使用name =“ email”而不是id =“ email”。
<input type="text" name="register_skype" ...... >
