从Spring Boot测试调用的@Caching方法[注有@Transactional]无法正常工作

Question

I'm using redis caching and spring boot annotations[@Cacheable and @CahePut], I made RedisManager transactionAware, which will use the outer transaction[callee of caching layer]

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

while testing as below, I'm using embedded 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
}

... Both times [ with and without @Transactional ] spring calls cache.put(key,result) without exception but it only persists values in case of without @Transactional.

Couldn't find much on internet, kudos to any help in advance.

In short just put @Commit or Rollback(false) annotation over your class or test method.

Spring by default rollback every Transaction after the test method.

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.
