Question

我正在开发spring-boot应用程序，我需要在检查其他信息之前验证用户信息。这是一个片段：

ALTER TABLE Marriage ADD CONSTRAINT CK_OlderThan 
CHECK (fn_OlderThanSon(Person_id,Relative_id) = 'True');

当用户来自其他路线 / create-sp-user 时，我必须重新验证用户：

java.sql.SQLSyntaxErrorException: ORA-01735: invalid ALTER TABLE option

你有什么想法吗？

祝你好运

就像Dominik所说，@ Valid注释在控制器中执行任何代码之前验证对象

如果要验证方法内的对象，则应使用自定义验证器。

实施org.springframework.validation.Validator并在控制器内调用validate方法。

@RequestMapping(value = "/create-sp-user", method = RequestMethod.POST)
    public String ceateCustomer(@Valid @RequestBody User user, BindingResult result){ 
      user.setSp(true);
      CustomValidator customValidator = new CustomValidator();
      customValidator.validate(user, result);

      if (result.hasErrors()){
        //do something
      } else {
        myService.create(user);
      }
}

向@Valid发出请求
