[英]RedisTemplate expire doesn't work
I'm trying to test expire method in RedisTemplate. 我正在尝试测试RedisTemplate中的expire方法。 For example, I store session in redis, and than try to retrieve session and check that values are the same.
例如,我将会话存储在redis中,然后尝试检索会话并检查值是否相同。 For expire session I use expire() method of redisTemplate and for getting expired session I use getExpire() method.
对于过期会话,我使用redisTemplate的expire()方法,对于过期会话,我使用getExpire()方法。 But it doesn't work.
但这是行不通的。 How can I test value, that stored in redis?
我如何测试存储在Redis中的值?
//without import and fields
public class Cache() {
private StringRedisTemplate redisTemplate;
public boolean expireSession(String session, int duration) {
return redisTemplate.expire(session, duration, TimeUnit.MINUTES);
}
}
//Test class without imports and fields
public class TestCache() {
private Cache cache = new Cache();
@Test
public void testExpireSession() {
Integer duration = 16;
String session = "SESSION_123";
cache.expireSession(session, duration);
assertEquals(redisTemplate.getExpire(session, TimeUnit.MINUTES), Long.valueOf(duration));
}
}
but test fails with AssertionError: 但是测试失败并显示AssertionError:
Expected :16 Actual :0
预期数:16实际数:0
UPDATE: I thought, that getExpire() method doesn't work, but in fact expire() method doesn't work. 更新:我以为,getExpire()方法不起作用,但实际上expire()方法不起作用。 It returns false.
返回false。 redisTemplate is a spring Bean that autowired to test class.
redisTemplate是一个自动连接到测试类的spring Bean。 There are many other test methods in TestCache class that work correctly.
TestCache类中还有许多其他测试方法可以正常工作。
I set up following code to perform a test on getExpire()
(jedis 2.5.2, spring-data-redis 1.4.2.RELEASE): 我设置了以下代码来对
getExpire()
进行测试(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. 根据您的Redis配置,如果重新启动Redis实例,则所有Redis数据都会消失。
You should also add an assertion to expireSession
( assertTrue(cache.expireSession(session, duration));
) to make sure, the expiry worked. 您还应该在
expireSession
( expireSession
( assertTrue(cache.expireSession(session, duration));
)中添加一个断言,以确保到期有效。
