我有我的 RequestParam，我需要驗(yàn)證它，但是 mu 自定義驗(yàn)證不適用，我的控制器@RestController@Validatedclass ExchangeController { private static final Logger logger = Logger.getLogger(ExchangeController.class.getName()); @SuppressWarnings("SpringJavaAutowiredFieldsWarningInspection") @Autowired @Qualifier("dataService") private CurrencyExchangeService currencyExchangeService; @RequestMapping(value = "/", method = RequestMethod.GET, produces = "application/json") public Object converting(@RequestParam("fromCurrency") @NotNull @CurrencyValidation String fromCurrency, @RequestParam("toCurrency") @NotNull String toCurrency, @RequestParam("amount") @NotNull String amount) throws IOException { BigDecimal convertedAmount = currencyExchangeService.convert(fromCurrency, toCurrency, new BigDecimal(amount)); return new ExchangeRateDTO(fromCurrency, toCurrency, new BigDecimal(amount), convertedAmount); }}和自定義驗(yàn)證public class ConstractCurrencyValidator implements ConstraintValidator<CurrencyValidation, String> { @Override public void initialize(CurrencyValidation currency) { } @Override public boolean isValid(String currency, ConstraintValidatorContext constraintValidatorContext) { return currency != null && Currency.getAvailableCurrencies().contains(Currency.getInstance(currency)); } }

需要在我的@interface CustomValidation. 這意味著驗(yàn)證也可以用于參數(shù)。
@Target({ ElementType.PARAMETER })

在配置中啟用參數(shù)驗(yàn)證：
@Bean
public Validator validator() {
return new LocalValidatorFactoryBean();
}
@Bean
public MethodValidationPostProcessor methodValidationPostProcessor() {
MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
methodValidationPostProcessor.setValidator(validator());
return methodValidationPostProcessor;
}
