[英]Hibernate @NotEmpty annotation equivalent in Javax.package or alternative
Is there a way to implement @NotEmpty
hibernate validation without writing custom validation?有没有办法在不编写自定义验证的情况下实现@NotEmpty
休眠验证? javax.validation package does not contain this annotation. javax.validation 包不包含此注释。 Only @NotNull
.只有@NotNull
。 But it does not validate for Non-null but empty values.但它不会验证非空但空值。 So I would like to see an alternative for @NotEmpty
.所以我想看到@NotEmpty
的替代@NotEmpty
。
Using @Pattern
?使用@Pattern
吗? How?如何?
NotEmpty 只是@NotNull
和@Size(min=1)
。
Please be aware that @NotEmpty will return valid for a List<> containing a null element.请注意,@NotEmpty 将对包含空元素的 List<> 返回有效。
Kind of bizarre in the case of a @QueryParam List<>在@QueryParam List<> 的情况下有点奇怪
As say Affe, I did a custom annotation, itself annotated with @NotNull and @Size(min=1) with a custom validator that iterates the collection and positions a boolean flag only if the elements are not null.正如 Affe 所说,我做了一个自定义注释,它本身用 @NotNull 和 @Size(min=1) 注释,并带有一个自定义验证器,该验证器仅在元素不为空时才迭代集合并定位一个布尔标志。
In the Hibernate @NotEmpty
source code after Hibernate 6, it told us use the standard javax.validation.constraints.NotEmpty
constraint instead:在 Hibernate 6 之后的 Hibernate @NotEmpty
源代码中,它告诉我们改用标准的javax.validation.constraints.NotEmpty
约束:
/**
* Asserts that the annotated string, collection, map or array is not {@code null} or empty.
*
* @author Emmanuel Bernard
* @author Hardy Ferentschik
*
* @deprecated use the standard {@link javax.validation.constraints.NotEmpty} constraint instead
*/

This new annotation comes from Bean Validation 2.0 (JSR 380).这个新注释来自 Bean Validation 2.0 (JSR 380)。 See:看:

For Hibernate it is deprecated in the newer version.对于 Hibernate,它在较新的版本中已被弃用。
With the newer version of Javax validation it has @Empty
使用较新版本的 Javax 验证,它具有@Empty
Use使用
import javax.validation.constraints.NotEmpty;
@NotEmpty
private List<Record> records;
