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.jb51.net/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=127.0.0.1:6380,127.0.0.1:6381,127.0.0.1:6382,127.0.0.1:6383,127.0.0.1:6384,127.0.0.1:6385 spring.redis.cluster.timeout=1000 spring.redis.cluster.max-redirects=3
3. 新建下面的两个类
@Configuration public 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; } }
@Configuration public 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 { @Autowired private RedisTemplate redisTemplate; @Test public 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。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持我们。
