嗨，我正在尝试在 Mysql 中插入一条记录，并在 Spring boot JPA 中获取插入用户的 ID。我收到以下错误。我见过几个这样的问题，但他们为此类输出提供了使用 JDBC 模板的答案。难道做不到吗？？或者这与其他一些问题有关。
Controller
@RequestMapping(value = "/signup", method = RequestMethod.POST)
public String createsignup(@RequestParam String name,@RequestParam String email,@RequestParam String password, ModelMap model) {
int userid = 0;
User user = new User(name,email);
userrepository.save(user);
userid = user.getId();
Authentication auth = new Authentication(email,password,userid);
authrepository.save(auth);
model.put("remember_token", auth.getRemember_token());
return "redirect:/profile";
}
型号
@Entity
公共(public)类用户{
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private String name;
private String email;
private String location;
public User() {
}
}
错误

最佳答案
经过大量搜索和尝试，我发现用户表是 Postgresql 中的默认表。这就是为什么它不允许。我已经更改了表名称并且它起作用了。还有其他方法可以重用它吗？
