Java并发场景下：如何确保页面请求版本与数据库或Redis版本一致？

// repositories.java
public interface PersonRepository extends JpaRepository<Person, Long> {
    Optional<Person> findByVersion(String version);
}

// controllers.java
@RestController
@RequestMapping("/api/persons")
public class PersonController {

    @Autowired
    private PersonService personService;

    @PostMapping
    public Person create(@RequestBody Person person) {
        return personService.create(person);
    }
}

// services.java
@Service
public class PersonService {

    @Autowired
    private PersonRepository personRepository;

    @Transactional
    public Person create(Person person) {
        checkVersion(person.getVersion()); // 版本校验
        return personRepository.save(person);
    }

    private void checkVersion(String version) {
        Optional<Person> dbPerson = personRepository.findByVersion(version);
        if (dbPerson.isEmpty() || !dbPerson.get().getVersion().equals(version)) {
            throw new VersionMismatchException("版本不一致");
        }
    }
}

// Aspects.java
@Aspect
@Component
public class VersionCheckAspect {

    @Before("@annotation(com.example.demo.annotations.VersionCheck)")
    public void checkVersion(JoinPoint joinPoint) {
        // 获取方法参数
        Object[] args = joinPoint.getArgs();

        // 提取版本号 (假设参数类型为Person)
        String version = ((Person) args[0]).getVersion();

        // 版本校验逻辑 (此处简化，实际需从数据库或Redis获取版本并比较)
        // ...  调用PersonService.checkVersion(version); ...
    }
}
