Springboot@Valid不能正常作業

我在Spring boot驗證方面面臨一個問題。目前，我正在使用Oracle JDK 11.0.12和Spring boot 2.5.4來構建我的專案。我添加了約束條件來驗證欄位，但它并不奏效。我的代碼在這里：

import lombok.Data;

import javax.validation.constraints.NotBlank。
import javax.validation.constraints.NotNull;
import java.io.Serializable;

@Data
public class LoginFormDTO implementsSerializable {

    private static final long serialVersionUID = 1L;

    @NotBlank(message = "Login must not be blank")/span>
    private String login;

    @NotNull(message = "必須提供密碼")
    private String password;

    private boolean rememberMe = false;
}

@RestController
@RequestMapping("/api")
public class AccountResource {

    // Logger and autowired components {

    @PostMapping("/authenticate")
    @ResponseBody
    public ResponseEntity<JWTToken> authorize(@Valid @RequestBody LoginFormDTO account){
        //一些代碼行
        return ResponseEntity.ok().body(new JWTToken(jwt))。
    }

pom.xml中的依賴性

我希望當我發送帶有body的POST請求時

{
  "login": null, //或空字串""，或空字串""。
  "密碼": "字串",
  "rememberMe": true
}

那么在執行我的authorize(@Valid @RequestBody LoginFormDTO account)函式中的代碼之前，服務器應該驗證欄位，然后拋出例外或錯誤（因為違反空約束），但它沒有。那么，彈簧驗證有什么問題，還是我錯過了什么？

你可以簡化你的Controller。你有太多的注釋在做同樣的事情，甚至還有一些奇怪的東西（你回傳ResponseEntity，但你又告訴Spring這個方法的回傳應該是Response Body）。

這可能無法解決@Valid的問題，但可以肯定的是，它將變得更加簡單：

@RestController
@RequestMapping("/api")
public class AccountResource {

    // Logger and autowired components {

    @PostMapping("/authenticate")
    @ResponseStatus(HttpStatus.OK)
    public JWTToken authorize(@Valid @RequestBody LoginFormDTO account) {
        //一些代碼行
        return new JWTToken（jwt）。
    }

@RestController本身注釋了@Controller和@ResponseBody，這意味著@RequestMapping方法默認承擔@ResponseBody語意，所以你不需要明確添加它。

我發現我的SwaggerConfig類應該使用BeanValidatorPluginsConfiguration.class而不是SpringValidatorAdapter.class在@Import({})。現在我的驗證器作業正常了。感謝Jo?o Dias支持我解決這個問題，
