spring boot如何实现redis哨兵模式下的多个master连接配置

Spring Boot可以通过配置多个RedisTemplate实例来实现Redis哨兵模式下的多个master连接。
步骤如下:
1. 在application.properties文件中配置哨兵节点信息:
```
spring.redis.sentinel.master=mymaster
spring.redis.sentinel.nodes=192.168.0.1:26379,192.168.0.2:26379,192.168.0.3:26379
```
2. 创建RedisConnectionFactory的bean:
```java
@Configuration
public class RedisConfig {
@Value("${spring.redis.sentinel.master}")
private String masterName;
@Value("${spring.redis.sentinel.nodes}")
private String sentinelNodes;
@Bean
public RedisConnectionFactory redisConnectionFactory() {
RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration()
.master(masterName)
.sentinel(sentinels())
.setDatabase(0);
return new JedisConnectionFactory(sentinelConfig);
}
private Set<RedisNode> sentinels() {
Set<RedisNode> nodes = new HashSet<>();
String[] parts = sentinelNodes.split(",");
for (String part : parts) {
String[] nodesParts = part.split(":");
String host = nodesParts[0];
Integer port = Integer.valueOf(nodesParts[1]);
nodes.add(new RedisNode(host, port));
}
return nodes;
}
}
```
3. 创建多个RedisTemplate实例:
```java
@Configuration
public class RedisTemplateConfig {
@Autowired
private RedisConnectionFactory redisConnectionFactory;
@Bean(name = "redisTemplate1")
public RedisTemplate<String, Object> redisTemplate1() {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return template;
}
@Bean(name = "redisTemplate2")
public RedisTemplate<String, Object> redisTemplate2() {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return template;
}
//...
}
```
4. 在需要使用RedisTemplate的地方使用@Qualifier注解指定使用哪个RedisTemplate实例:
```java
@Service
public class ExampleService {
@Autowired
@Qualifier("redisTemplate1")
private RedisTemplate<String, Object> redisTemplate1;
@Autowired
@Qualifier("redisTemplate2")
private RedisTemplate<String, Object> redisTemplate2;
//...
}
```
