是否可以在Spring MVC REST端点中验证@RequestParam? [英] Is it possible to validate @RequestParam in Spring MVC REST endpoint?
本文介绍了是否可以在Spring MVC REST端点中验证@RequestParam?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在泽西岛2,可以这样做:
In Jersey 2 it is possible to do this:
@GET
@PATH("user/{email}")
public IDto getUser(@NotNull @Email @PathParam("email") String validEmail) {
return userManagementService.findUserByEmail(validEmail);
}
但是我无法在Spring MVC中做类似工作,似乎验证仅在@RequestBody中提供对象或使用SpringMVC表单时完成,例如以下操作无效:
But I cannot make something similar to work in Spring MVC, it seems that the validation is only done when providing an object in @RequestBody or using an SpringMVC Form, for example the following won't work:
@RequestMapping(value="/user/{email}", method = RequestMethod.GET)
public @ResponseBody IDto getUser(@NotNull @Email @PathVariable String validEmail) {
return userManagementService.findUserByEmail(validEmail);
}
还有其他类似的问题,但这些问题似乎都面向Spring MVC UI应用程序,在我的情况下,它只是一个返回JSON响应的REST API,所以我没有任何View映射/绑定到控制器。
There are other similar questions, but those seem to be oriented to Spring MVC UI applications, in my case it is only a REST API which returns JSON response so I don't have any View to map/bind to the controller.
推荐答案
