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RedisTemplate1、引入依赖:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
2、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)); }
