redis主从,实现类似mysql的读写分离效果。在代码层面需要执行slave host吗?
目前是通过jedis客户端JedisSentinelPool连接哨兵集群,查看日志输出应该连接的是master的host
读请求会被自动路由到slave吗?

主的配置好ip和端口,从的配置好Slaveof的master地址和端口号,哨兵监控master的ip和端口号,java代码直接master的name和密码就行了。

public static void main(String[] args) {
Set<String> sentinels = new HashSet<String>();
String hostAndPort1 = "127.0.0.1:26379";
String hostAndPort2 = "127.0.0.1:26380";
sentinels.add(hostAndPort1);
sentinels.add(hostAndPort2);
String clusterName = "mymaster";
String password = "123456";
JedisSentinelPool redisSentinelJedisPool = new JedisSentinelPool(clusterName,sentinels,password);
Jedis jedis = null;
try {
jedis = redisSentinelJedisPool.getResource();
System.out.println(jedis.get("key"));
} catch (Exception e) {
e.printStackTrace();
} finally {
redisSentinelJedisPool.returnBrokenResource(jedis);
}
redisSentinelJedisPool.close();
