最近在学习使用Thymeleaf,想使用表单向后台提交数据时，遇到了一些问题
###表单
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Title</title>
</head>
<body>
<form th:action="@{/user/register}" method="post">
<a>ID：<input type="text" name="userId"><br/></a>
<a>昵称： <input type="text" name="nickname" ><br/></a>
<a>密码：<input type="password" name="password" ></a>
<input type="submit" value="提交">
</form>
</body>
</html>
###Controller
@Controller
@RequestMapping("/user")
public class UserController {
@PostMapping("/register")
public String login(User user){
System.out.println(user);
return "/success.html";
}
}
###错误
WARN 2384 --- [nio-8080-exec-2] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported]
