我有一個(gè)運(yùn)行正常的 Spring Boot Web 應(yīng)用程序。我注意到兩個(gè)@Repositorybean 有很多共同點(diǎn)，所以我使用抽象超類重構(gòu)了它們，現(xiàn)在我的應(yīng)用程序壞了。我已經(jīng)仔細(xì)檢查過，這是我在工作狀態(tài)和非工作狀態(tài)之間所做的唯一更改。誰能看到我做錯了什么？這是我的工作代碼：public class One { ... }public class Two { ... }@Repositorypublic class RepoOne {    private final ISource<One> sourceOne;    private ICache<One> cache;    @Value("${com.example.lifetime.one}")    private int lifetime;    public RepoOne(ISource<One> sourceOne) {       this.sourceOne = sourceOne;    }    @PostConstruct    public void createCache() {       Duration lifetime = Duration.ofMinutes(this.lifetime);       this.cache = new Cache<>(lifetime, sourceOne);    }    public One get(String key) {      return cache.get(key);    }}@Repositorypublic class RepoTwo {    private final ISource<Two> sourceTwo;    private ICache<Two> cache;    @Value("${com.example.lifetime.two}")    private int lifetime;    public RepoOne(ISource<Two> sourceTwo) {        this.sourceTwo = sourceTwo;    }    @PostConstruct    public void createCache() {        Duration lifetime = Duration.ofMinutes(this.lifetime);        this.cache = new Cache<>(lifetime, sourceTwo);    }    public Two get(String key) {        return cache.get(key);    }}@Servicepublic class RepoService {    private final RepoOne repoOne;    private final RepoTwo repoTwo;    public RepoService(RepoOne repoOne, RepoTwo repoTwo) {        this.repoOne = repoOne;        this.repoTwo = repoTwo;    }    public void doSomething(String key) {        One one = repoOne.get(key);        ...    }}這是我重構(gòu)的代碼，我在其中引入了一個(gè)抽象的通用超類。
