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);
}
