如何在spring启动时加载@Cache？

像以前一样使用缓存，添加调度程序以更新缓存，下面是代码段。

@Servicepublic class CacheScheduler {    @Autowired    BookDao bookDao;    @Autowired    CacheManager cacheManager;    @PostConstruct    public void init() {        update();        scheduleUpdateAsync();    }    public void update() {        for (Book book : bookDao.findAll()) { cacheManager.getCache("books").put(book.getIsbn(), book);        }    }}

确保你

KeyGenerator

putToCache

BookService

@CachePut(value = "books", key = "#book.isbn")public Book putToCache(Book book) {    return book;}
