我正在尝试测试Spring缓存支持(如此处所述)用于扩展了JpaRepository
的Spring Data JPA存储库,并且我实际上遇到了配置问题。
这是我的存储库方法:
@Cacheable(value = CacheConfiguration.DATABASE_CACHE_NAME)
Member findByEmail(String email);
这里是我的缓存配置:
CacheConfiguration:
@Configuration
@EnableCaching
public class CacheConfiguration implements CachingConfigurer {
public static final String DATABASE_CACHE_NAME = "cache.database";
@Bean
@Override
public CompositeCacheManager cacheManager() {
CompositeCacheManager cacheManager = new CompositeCacheManager(simpleCacheManager());
cacheManager.setFallbackToNoOpCache(Boolean.FALSE);
return cacheManager;
}
@Bean
public CacheManager simpleCacheManager() {
SimpleCacheManager simpleCacheManager = new SimpleCacheManager();
List<ConcurrentMapCache> cacheList = new ArrayList<>();
cacheList.add(createConcurrentMapCache(60L, DATABASE_CACHE_NAME, 50L));
simpleCacheManager.setCaches(cacheList);
return simpleCacheManager;
}
private ConcurrentMapCache createConcurrentMapCache(Long timeToLive, String name, long cacheSize) {
CacheBuilder<Object, Object> cacheBuilder = CacheBuilder.newBuilder().expireAfterWrite(timeToLive, TimeUnit.SECONDS);
if (cacheSize >= 0) {
cacheBuilder.maximumSize(cacheSize);
}
ConcurrentMap<Object, Object> map = cacheBuilder.build().asMap();
return new ConcurrentMapCache(name, map, false);
}
@Override
public KeyGenerator keyGenerator() {
return new SimpleKeyGenerator();
}
}
这是我的测试:
@ActiveProfiles(Profiles.TEST)
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { FullIntegrationTestConfiguration.class, BaseTestConfiguration.class, MemberCachingIntegrationTest.Config.class })
public class MemberCachingIntegrationTest {
private static final Member MEMBER_ONE = new Member();
private static final Member MEMBER_TWO = new Member();
@Autowired
private MemberRepository memberRepositoryMock;
@Before
public void setup() {
when(memberRepositoryMock.findByEmail(eq("foo@foo.com"))).thenReturn(MEMBER_ONE);//NPE Here
when(memberRepositoryMock.findByEmail(eq("bar@bar.com"))).thenReturn(MEMBER_TWO);
}
@Test
public void testFindByEmail() {
Member firstInvocation = memberRepositoryMock.findByEmail("foo@foo.com");
assertThat(firstInvocation, is(MEMBER_ONE));
Member secondInvocation = memberRepositoryMock.findByEmail("foo@foo.com");
assertThat(secondInvocation, is(MEMBER_ONE));
verify(memberRepositoryMock, times(1)).findByEmail("foo@foo.com");
}
@Profile(Profiles.TEST)
@Configuration
static class Config {
@Bean
public MemberRepository memberRepositoryMock() {
return mock(MemberRepository.class);
}
}
}
通过运行上述测试,我注意到一个类型为
SimpleKey
的对象作为key传递,而value传递了ConcurrentMapCache
中的null
值。@Override
public void put(Object key, Object value) {
this.store.put(key, toStoreValue(value));
}
在我的情况下,存储类型为:
com.google.common.cache.LocalCache
,put方法有一个空值检查,导致NPE(NullPointerException)......
