maven依赖
springboot整合jedisCluster相当简单,maven依赖如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
加了这一个依赖之后就不要再加上jedis的这一个依赖了:
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>
加这个可能在本身测试的时候,可能会导致jedisCluster对象正常,但是在测试的时候会发现set数据的时候会出现问题,我把jedis的依赖去掉之后,这个问题解决,因此不要加上jedis的这一个依赖,spring-boot-starter-redis这一个引入相关jedis需要的包。
application.properties配置
这里的配置相当简单,只需要天上redis的相关地址就行了,如下:
#redis cluster
spring.redis.cache.clusterNodes=192.168.xx.xx:6379,192.168.xx.:6380,192.168.xx.xx:6381
spring.redis.cache.commandTimeout=5000
定义一个类命名问RedisProperties,在里面定义的字段与配置文件中相对应,即可取到配置,如下:
@Component
@ConfigurationProperties(prefix = "spring.redis.cache")
@Data
public class RedisProperties {
private String clusterNodes;
private Integer commandTimeout;
}
JedisClusterConfig
@Configuration
@ConditionalOnClass({JedisCluster.class})
@EnableConfigurationProperties(RedisProperties.class)
public class JedisClusterConfig {
@Inject
private RedisProperties redisProperties;
@Bean
@Singleton
public JedisCluster getJedisCluster() {
String[] serverArray = redisProperties.getClusterNodes().split(",");
Set<HostAndPort> nodes = new HashSet<>();
for (String ipPort: serverArray) {
String[] ipPortPair = ipPort.split(":");
nodes.add(new HostAndPort(ipPortPair[0].trim(),Integer.valueOf(ipPortPair[1].trim())));
}
return new JedisCluster(nodes, redisProperties.getCommandTimeout());
}
}
配置就完成,现在进行测试一次。
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = SpringBootWebApplication.class)
@WebAppConfiguration
public class TestJedisCluster {
@Inject
private JedisCluster jedisCluster;
@Test
public void testJedis() {
jedisCluster.set("test_jedis_cluster", "38967");
Assert.assertEquals("38967", jedisCluster.get("test_jedis_cluster"));
jedisCluster.del("test_jedis_cluster");
}
}
使用RedisTemplate,添加如下依赖:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
配置文件application.yml在添加配置(假设有6个nodes):
spring:
redis:
cluster:
nodes:
- 192.168.0.17:6390
- 192.168.0.17:6391
- 192.168.0.17:6392
- 192.168.0.9:6390
- 192.168.0.9:6391
- 192.168.0.9:6392
代码测试
@Autowired
RedisTemplate<String, String> redisTemplate;
@Test
public void redisTest() {
String key = "redisTestKey";
String value = "I am test value";
ValueOperations<String, String> opsForValue = redisTemplate.opsForValue();
//数据插入测试:
opsForValue.set(key, value);
String valueFromRedis = opsForValue.get(key);
logger.info("redis value after set: {}", valueFromRedis);
assertThat(valueFromRedis, is(value));
//数据删除测试:
redisTemplate.delete(key);
valueFromRedis = opsForValue.get(key);
logger.info("redis value after delete: {}", valueFromRedis);
assertThat(valueFromRedis, equalTo(null));
}
