I set up following code to perform a test on getExpire()
(jedis 2.5.2, spring-data-redis 1.4.2.RELEASE):
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = DemoApplication.class)
public class DemoApplicationTests {
@Autowired
private RedisTemplate<String, String> template;
@Test
public void contextLoads() {
template.getConnectionFactory().getConnection().flushAll();
assertFalse(template.hasKey("key"));
assertFalse(template.expire("key", 10, TimeUnit.MINUTES));
assertEquals(0, template.getExpire("key", TimeUnit.MINUTES).longValue());
template.opsForHash().put("key", "hashkey", "hashvalue");
assertTrue(template.hasKey("key"));
assertTrue(template.expire("key", 10, TimeUnit.MINUTES));
assertTrue(template.getExpire("key", TimeUnit.MINUTES) > 8);
}
}
Depending on your Redis configuration, all Redis data is gone if you restart your Redis instance.
You should also add an assertion to expireSession
(assertTrue(cache.expireSession(session, duration));
) to make sure, the expiry worked.
