通过编写自定义ConstraintValidator实现类来实现此功能。以下是示例代码：

首先，创建一个注释类，以添加一个前缀，并将其应用于一个嵌套对象：

@Target({ElementType.FIELD}) @Retention(RetentionPolicy.RUNTIME) @Constraint(validatedBy = {PrefixValid.PrefixValidator.class}) public @interface PrefixValid {

String message() default "Invalid object";

Class[] groups() default {};

Class[] payload() default {};

String prefix() default "";

Class[] targetClasses() default {};

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@interface List {
    PrefixValid[] value();
}

class PrefixValidator implements ConstraintValidator {

    private String prefix;

    private Class[] targetClasses;

    private Validator validator;

    @Override
    public void initialize(PrefixValid prefixValid) {
        this.prefix = prefixValid.prefix();
        this.targetClasses = prefixValid.targetClasses();
        validator = Validation.buildDefaultValidatorFactory().getValidator();
    }

    @Override
    public boolean isValid(Object o, ConstraintValidatorContext constraintValidatorContext) {
        boolean result = true;
        if (o != null) {
            Set> violations = validator.validate(o, targetClasses);
            if (!violations.isEmpty()) {
                result = false;
                for (ConstraintViolation
