java - 从 spring boot 测试调用的@Caching 方法[用@Transactional 注释] 不起作用

Question

我正在使用 redis 缓存和 spring boot 注释[@Cacheable 和@CahePut]，我制作了 RedisManager transactionAware，它将使用外部事务[缓存层的调用者]

@Bean
public RedisCacheManager cacheManager() {
    RedisCacheManager rcm = 
    RedisCacheManager.builder(redisConnectionFactory())
            .cacheDefaults(cacheConfiguration())
            .transactionAware()
            .build();
    return rcm;
}

在进行如下测试时，我使用的是嵌入式 redis-:

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureTestDatabase
@Transactional
public class RoleServiceImplTest extends TestingProfile {

@Before
public void setup() throws Exception {
    //setup server and services

    redisServer = new RedisServer(redisPort);
    redisServer.start();
}
@Test
    public void getUsersForRoleForTemplateRole() {
    // call to caching layer methods directly annotated with @Cachable
}

...两次 [带和不带 @Transactional] spring 都毫无异常(exception)地调用 cache.put(key,result) 但它只在没有 @Transactional 的情况下保留值。

在互联网上找不到太多信息，感谢提前提供的任何帮助。

简而言之，只需将 @Commit 或 Rollback(false) 注释放在您的类或测试方法上即可。

在测试方法之后，Spring 默认回滚每个事务。

https://docs.spring.io/spring/docs/current/spring-framework-reference/testing.html#testcontext-tx

In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener, which is configured by default, even if you do not explicitly declare @TestExecutionListeners on your test class. To enable support for transactions, however, you must configure a PlatformTransactionManager bean in the ApplicationContext that is loaded with @ContextConfiguration semantics (further details are provided later). In addition, you must declare Spring’s @Transactional annotation either at the class or the method level for your tests.

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/test/context/transaction/TransactionalTestExecutionListener.html

Declarative Rollback and Commit Behavior

By default, test transactions will be automatically rolled back after completion of the test; however, transactional commit and rollback behavior can be configured declaratively via the @Commit and @Rollback annotations at the class level and at the method level.
