列表中的Javax验证

Question

所以我有一个类和一个字符串列表字段，我想验证它们中的每一个，但它不起作用，我尝试了这个，但没有成功：

public class Info {
@NotNull
@NotEmpty
private List<@Email(message = "uncorrect email") String> emails;
}

我也试过这个，但没有成功：

public class Info {
@NotNull
@NotEmpty
private @Valid List<@Email(message = "uncorrect email") String> emails;
}

但当它只是一个字符串时，它工作得很好。

public class Info {
@NotNull
@NotEmpty
private @Email(message = "uncorrect email") String email;
}

我怎样才能实现我想要的？

Answer 1

hibernate验证器的最新版本支持它。您可以进行以下更改以实现所需的验证行为。

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.7.0</version>
</dependency>
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>2.0.1.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.0.13.Final</version>
</dependency>
</dependencies>

Java Bean

import java.util.List;
import javax.validation.constraints.Email;
import javax.validation.constraints.NotEmpty;
import javax.validation.constraints.NotNull;
public class Info {
@NotNull
@NotEmpty
private List<@Email(message = "List contain atleast one incorrect email") String> emails;
@NotNull
@NotEmpty
@Email(message = "incorrect email")
private String email;
public List<String> getEmails() {
return emails;
}
public void setEmails(List<String> emails) {
this.emails = emails;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "Info [emails=" + emails + ", email=" + email + "]";
}
}

添加@Valid

@PostMapping("/post")
public void post(@RequestBody @Valid Info info) {
System.out.println(info);
}
