Question

我的缓存配置如下;

 public void read()
    {
        //port is already open
        port.Write("AT" + System.Environment.NewLine);
        //Thread.Sleep(1000);
        port.Write("AT+CMGF=1" + System.Environment.NewLine);
        //Thread.Sleep(1000);
        port.Write("AT+CMGL=\"ALL\"\r" + System.Environment.NewLine);
        //Thread.Sleep(3000);
        //MessageBox.Show(port.ReadExisting());


        Regex r = new Regex(@"\+CMGL: (\d+),""(.+)"",""(.+)"",(.*),""(.+)""\r\n(.+)\r\n");
        Match m = r.Match(port.ReadExisting());
        while (m.Success)
        {
            string a = m.Groups[1].Value;
            string b = m.Groups[2].Value;
            string c = m.Groups[3].Value;
            string d = m.Groups[4].Value;
            string ee = m.Groups[5].Value;
            string f = m.Groups[6].Value;

            ListViewItem item = new ListViewItem(new string[] { a, b, c, d, ee, f });
            lvwMessages.Items.Add(item);
            m = m.NextMatch();
        }
        lvwMessages.AutoResizeColumns(ColumnHeaderAutoResizeStyle.ColumnContent);
        lvwMessages.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
        sd.Width = 0;
    }

我要测试的服务：

@Configuration
public class CacheConfiguration {

    @Bean
    public CacheManager cacheManager(Ticker ticker) {
        CaffeineCache bookCache = buildCache("books", ticker, 30);
        SimpleCacheManager cacheManager = new SimpleCacheManager();
        cacheManager.setCaches(Collections.singletonList(bookCache));
        return cacheManager;
    }

    private CaffeineCache buildCache(String name, Ticker ticker, int minutesToExpire) {
        return new CaffeineCache(name, Caffeine.newBuilder()
                .expireAfterWrite(minutesToExpire, TimeUnit.MINUTES)
                .maximumSize(100)
                .ticker(ticker)
                .build());
    }

    @Bean
    public Ticker ticker() {
        return Ticker.systemTicker();
    }
}

存储库中的必需方法使用@Service public class TestServiceImpl implements TestService { private final BookRepository bookRepository; // interface @Autowired public TestServiceImpl(final BookRepository bookRepository) { this.bookRepository = bookRepository; } @Override public Book getByIsbn(String isbn) { return bookRepository.getByIsbn(isbn); } }进行注释。

@Cacheable("books")

我需要编写一个显示缓存工作的测试。所以我在test中创建了另一个@Override @Cacheable("books") public Book getByIsbn(String isbn) { LOGGER.info("Fetching Book..."); simulateSlowService(); // Wait for 5 secs return new Book(isbn, "Some book"); } bean来覆盖ticker中存在的bean。代码;

CacheConfiguration

但它在标有@RunWith(SpringRunner.class) @SpringBootTest public class TestServiceTests { private static final String BOOK_ISBN = "isbn-8442"; @SpyBean private BookRepository bookRepository; @Autowired private TestService testService; @Configuration @Import(SpringBootCacheApplication.class) public static class TestConfiguration { //testCompile('com.google.guava:guava-testlib:23.6-jre') static FakeTicker fakeTicker = new FakeTicker(); @Bean public Ticker ticker() { return fakeTicker::read; } } @Before public void setUp() { Book book = fakeBook(); doReturn(book) .when(bookRepository) .getByIsbn(BOOK_ISBN); } private Book fakeBook() { return new Book(BOOK_ISBN, "Mock Book"); } @Test public void shouldUseCache() { // Start At 0 Minutes testService.getByIsbn(BOOK_ISBN); verify(bookRepository, times(1)).getByIsbn(BOOK_ISBN); // After 5 minutes from start, it should use cached object TestConfiguration.fakeTicker.advance(5, TimeUnit.MINUTES); testService.getByIsbn(BOOK_ISBN); verify(bookRepository, times(1)).getByIsbn(BOOK_ISBN); // FAILS HERE // After 35 Minutes from start, it should call the method again TestConfiguration.fakeTicker.advance(30, TimeUnit.MINUTES); testService.getByIsbn(BOOK_ISBN); verify(bookRepository, times(2)).getByIsbn(BOOK_ISBN); } }的行上显示消息;

//FAILS HERE

为什么会失败？它不应该使用缓存吗？或者我的测试错了？

非常感谢任何帮助或指示！：）

Could not load driverClass org.postgresql.Driver

当然，这里失败了。因为在您已经调用过此方法一次之前大约有4行。在此检查中，您应该放置FROM vertx/vertx3。在下一次检查时，调用次数应为verify(bookRepository, times(1)).getByIsbn(BOOK_ISBN); // FAILS HERE
