@Configuration
public class ValidatorConfig extends WebMvcConfigurerAdapter {
@Bean
public Validator validator() {
ValidatorFactory validatorFactory = Validation.byProvider(HibernateValidator.class)
.configure()
// 将fail_fast设置为true即可，如果想验证全部，则设置为false或者取消配置即可
.failFast(true)
// .addProperty("hibernate.validator.fail_fast", "true")
.buildValidatorFactory();
return validatorFactory.getValidator();
}
/**

@Bean

methodValidationPostProcessor.setValidator(validator());
return methodValidationPostProcessor;
}
@Override
public org.springframework.validation.Validator getValidator() {
return new SpringValidatorAdapter(validator());
}
}其中methodValidationPostProcessor是對requestParam起作用
#繼承 WebMvcConfigurerAdapter 並且重寫getValidator()方法，是讓spring的請求校驗Validator使用我們上邊的validator，讓設定的failFast生效，具體可參考org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport#mvcValidator方法

}#如果是
@RequestParam這樣直接寫參數校驗的話，在類別上或對應方法上加上Validated註解，如果是實體類別接受的話，在參數中的實體前加上@Valid即可
