Springboot2.X集成redis集群(Lettuce)连接的方法

前提：搭建好redis集群环境，搭建方式请看：https://www.VeVB.COm/article/143749.htm

1. 新建工程，pom.xml文件中添加redis支持

<dependency>  <groupId>org.springframework.boot</groupId>  <artifactId>spring-boot-starter-data-redis</artifactId></dependency>

2.配置application.properties

spring.redis.cluster.nodes=127.0.0.1:6380,127.0.0.1:6381,127.0.0.1:6382,127.0.0.1:6383,127.0.0.1:6384,127.0.0.1:6385spring.redis.cluster.timeout=1000spring.redis.cluster.max-redirects=3

3. 新建下面的两个类

@Configurationpublic class RedisConfiguration {  @Resource  private LettuceConnectionFactory myLettuceConnectionFactory;  @Bean  public RedisTemplate<String, Serializable> redisTemplate() {    RedisTemplate<String, Serializable> template = new RedisTemplate<>();    template.setKeySerializer(new StringRedisSerializer());    template.setValueSerializer(new GenericJackson2JsonRedisSerializer());    template.setConnectionFactory(myLettuceConnectionFactory);    return template;  }} 

@Configurationpublic class RedisFactoryConfig {  @Autowired  private Environment environment;  @Bean  public RedisConnectionFactory myLettuceConnectionFactory() {    Map<String, Object> source = new HashMap<String, Object>();    source.put("spring.redis.cluster.nodes", environment.getProperty("spring.redis.cluster.nodes"));    source.put("spring.redis.cluster.timeout", environment.getProperty("spring.redis.cluster.timeout"));    source.put("spring.redis.cluster.max-redirects", environment.getProperty("spring.redis.cluster.max-redirects"));    RedisClusterConfiguration redisClusterConfiguration;    redisClusterConfiguration = new RedisClusterConfiguration(new MapPropertySource("RedisClusterConfiguration", source));    return new LettuceConnectionFactory(redisClusterConfiguration);  }} 

4.执行测试

@SpringBootTest@RunWith(SpringRunner.class)public class RedisConfigurationTest {  @Autowiredprivate RedisTemplate redisTemplate;@Testpublic void redisTemplate() throws Exception {    redisTemplate.opsForValue().set("author", "Damein_xym");}}

5. 验证，使用Redis Desktop Manager 连接redis节点，查看里面的数据是否存在author，有如下显示，证明成功。
