Spring验证非空元素的字符串列表

public class MyObject {
    @NotEmpty
    private List<String> myList;
    
    // getter and setter
}

public class MyObject {
    @NotBlank
    private List<String> myList;
    
    // getter and setter
}

public class NotEmptyElementValidator implements ConstraintValidator<NotEmptyElement, List<String>> {

    @Override
    public void initialize(NotEmptyElement constraintAnnotation) {
        // 初始化验证器
    }

    @Override
    public boolean isValid(List<String> value, ConstraintValidatorContext context) {
        if (value == null) {
            return false;
        }
        for (String element : value) {
            if (element != null && !element.trim().isEmpty()) {
                return true;
            }
        }
        return false;
    }
}

public class MyObject {
    @NotEmptyElement
    private List<String> myList;
    
    // getter and setter
