我尝试使用注释验证,但它无法正常工作。 这是我的服务界面,我正在应用验证:
package com.tehras.web.service;
import com.tehras.web.annotations.ValidCategory;
import com.tehras.web.models.MenuCategory;
import org.springframework.stereotype.Service;
import org.springframework.validation.annotation.Validated;
import javax.validation.Valid;
import java.util.List;
/**

@Validated
@Service
public interface IMenuCategoriesService {
/*
@Return List<MenuCategory>
*/
public List<MenuCategory> getMenuCategories();
/*
@Return boolean
*/
public boolean addMenuCategory(@ValidCategory MenuCategory menuCategory);
/*
@Return boolean
*/
public boolean removeMenuCategories(List<MenuCategory> menuCategoryList);
public boolean containsCategoryName(String categoryName);
}
这是我的验证课程
@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER})
@Retention(RUNTIME)
@Documented
@Constraint(validatedBy = {ValidCategoryImpl.class, ValidCategoryNameImpl.class})
public @interface ValidCategory {
String message() default "This Category Does not Seem to Allowed";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default { };
}
最后我的Impl课程:
@Component
public class ValidCategoryImpl implements ConstraintValidator<ValidCategory, MenuCategory> {
@Autowired
IMenuCategoriesService menuCategoriesService;
@Override
public void initialize(ValidCategory constraintAnnotation){
}
@Override
public boolean isValid(MenuCategory menuCategory, ConstraintValidatorContext context){
return menuCategoriesService.containsCategoryName(menuCategory.getTitle());
}
}
请帮忙!我已经被困住了,无法修复它! 当我通过menuCategory时,它甚至没有进入验证方法?请帮忙!
..无法添加通知,但为了回答原因,我认为这是:
类似于调用@NotNull或@Size的方式,我创建了我的自定义类,我的实现是这样的 - ConstraintValidator,所以当MenuCategory存在时,它应该进入这个实现方法,因为我有@ValidCategory设置要做所以。你的意见是什么?如何确保验证发生?
