redis-sentinel哨兵集群搭建并整合springboot
在Spring Boot中使用Redis Sentinel,你需要进行以下步骤:
1. 添加依赖:在你的`pom.xml`文件中添加以下依赖:
```xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<exclusions>
<exclusion>
<groupId>io.lettuce</groupId>
<artifactId>lettuce-core</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
```
2. 配置Redis Sentinel:在`application.properties`文件中添加以下配置:
```properties
spring.redis.sentinel.master=your-master-name
spring.redis.sentinel.nodes=host1:port1,host2:port2,host3:port3
```
将`your-master-name`替换为你的Redis Sentinel的master名称,将`host1:port1,host2:port2,host3:port3`替换为你的Redis Sentinel的节点列表。
3. 创建Redis连接工厂:在你的代码中创建一个`RedisConnectionFactory`实例,例如:
```java
@Configuration
public class RedisConfig {
@Value("${spring.redis.sentinel.master}")
private String sentinelMaster;
@Value("${spring.redis.sentinel.nodes}")
private String sentinelNodes;
@Bean
public RedisConnectionFactory redisConnectionFactory() {
RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration()
.master(sentinelMaster)
.sentinel(hostAndPortSet(sentinelNodes));
return new JedisConnectionFactory(sentinelConfig);
}
private Set<RedisNode> hostAndPortSet(String nodes) {
Set<RedisNode> hostAndPortSet = new HashSet<>();
String[] hostAndPorts = nodes.split(",");
for (String hostAndPort : hostAndPorts) {
String[] parts = hostAndPort.split(":");
hostAndPortSet.add(new RedisNode(parts, Integer.parseInt(parts)));
}
return hostAndPortSet;
}
}
```
4. 使用RedisTemplate:在你的代码中使用`RedisTemplate`来操作Redis数据,例如:
```java
@Service
public class RedisService {
@Autowired
private RedisTemplate<String, String> redisTemplate;
public void setValue(String key, String value) {
redisTemplate.opsForValue().set(key, value);
}
public String getValue(String key) {
return redisTemplate.opsForValue().get(key);
}
}
```
现在你可以在Spring Boot中使用Redis Sentinel了。只需根据你的需求创建相应的服务类,并注入`RedisTemplate`来访问Redis数据。
