要配置Spring Cloud Redis集群,需要按照以下步骤进行配置:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
# Redis集群节点信息
spring.redis.cluster.nodes=127.0.0.1:7001,127.0.0.1:7002,127.0.0.1:7003
# Redis连接池配置
spring.redis.cluster.max-idle=8
spring.redis.cluster.min-idle=1
spring.redis.cluster.max-active=8
spring.redis.cluster.max-wait=3000
@Configuration
public class RedisConfig {
@Value("${spring.redis.cluster.nodes}")
private String clusterNodes;
@Value("${spring.redis.cluster.max-idle}")
private int maxIdle;
@Value("${spring.redis.cluster.min-idle}")
private int minIdle;
@Value("${spring.redis.cluster.max-active}")
private int maxActive;
@Value("${spring.redis.cluster.max-wait}")
private long maxWait;
@Bean
public RedisClusterConfiguration redisClusterConfiguration() {
RedisClusterConfiguration redisClusterConfiguration = new RedisClusterConfiguration(Arrays.asList(clusterNodes.split(",")));
return redisClusterConfiguration;
}
@Bean
public JedisConnectionFactory jedisConnectionFactory(RedisClusterConfiguration redisClusterConfiguration) {
JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisClusterConfiguration);
return jedisConnectionFactory;
}
@Bean
public RedisTemplate<String, Object> redisTemplate(JedisConnectionFactory jedisConnectionFactory) {
RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(jedisConnectionFactory);
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
return redisTemplate;
}
@Bean
public RedisCacheManager redisCacheManager(RedisTemplate<String, Object> redisTemplate) {
RedisCacheManager redisCacheManager = new RedisCacheManager(redisTemplate);
redisCacheManager.setUsePrefix(true);
return redisCacheManager;
}
}
@Autowired
private RedisTemplate<String, Object> redisTemplate;
public void set(String key, Object value) {
redisTemplate.opsForValue().set(key, value);
}
public Object get(String key) {
return redisTemplate.opsForValue().get(key);
}
public boolean exists(String key) {
return redisTemplate.hasKey(key);
}
这样就完成了Spring Cloud中使用Redis集群的配置。需要注意的是,Redis集群的节点信息和连接池的配置可以根据实际情况进行修改。
