<h2 id="2-添加-Redis-配置"><a href="#2-添加-Redis-配置" class="headerlink" title="2. 添加 Redis 配置"></a>2. 添加 Redis 配置</h2><pre><code>spring:
redis:
cluster:
nodes: 127.0.0.1:9001,127.0.0.1:9002,127.0.0.1:9003
password: ******

database: 0
jedis:
pool:
max-idle: 8
min-idle: 1

</code></pre>
<p>这里我们使用了 jedis 连接池。</p>
<h2 id="3-创建操作-Redis-的-Service"><a href="#3-创建操作-Redis-的-Service" class="headerlink" title="3. 创建操作 Redis 的 Service"></a>3. 创建操作 Redis 的 Service</h2><pre><code>@Service
public class RedisServiceImpl implements RedisService {
@Autowired
private StringRedisTemplate stringRedisTemplate;
private Logger logger = LoggerFactory.getLogger(RedisServiceImpl.class);
@Override
public void setStr(String key, String value) {
logger.info("插入 Redis 数据。入参：key：{}，value：{}", key, value);
ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
operations.set(key, value);
}
@Override
public String getStr(String key) {
logger.info("获取 Redis 数据。入参：key：{}", key);
ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
String value = operations.get(key);
logger.info("获取 Redis 数据。出参：value：{}", value);
return value;
}
@Override
public void delStr(String key) {
logger.info("删除 Redis 数据。入参：key：{}", key);
ValueOperations<String, String> operations = stringRedisTemplate.opsForValue();
operations.getOperations().delete(key);
}
</code></pre>
<p>操作 Redis 的主要类是 <code>stringRedisTemplate</code>,这个类可以获取不同类型的 Redis操作对象。</p>
<pre><code>Stirng 类型：stringRedisTemplate.opsForValue()
List 类型：stringRedisTemplate.opsForList()
Set 类型：stringRedisTemplate.opsForSet()
Hash 类型：stringRedisTemplate.opsForHash()
</code></pre>
<p>可以看到，opsForXXX() 不能删除 Redis 中的key，这个时候可以使用下面的方法，获取<code>RedisOperations</code> 对象。通过该对象进行一些 Redis 的操作。</p>
<pre><code>opsForHash().getOperations().delete(key);
</code></pre>
<h2 id="4-单元测试"><a href="#4-单元测试" class="headerlink" title="4. 单元测试"></a>4. 单元测试</h2><p>我们针对这个 Service 写个单元测试，测试一下</p>
<pre><code>@RunWith(SpringRunner.class)
@SpringBootTest()
public class RedisServiceImplTest {
@Autowired
private RedisService redisService;
@Test
public void setStr() throws Exception {
redisService.setStr("TEST","1234");
}
@Test
public void getStr() throws Exception {
System.out.println(redisService.getStr("TEST"));
}
@Test
public void delStr() throws Exception {
redisService.delStr("TEST");
}
}
