redis集群配置：
在使用spring的RedisTemplate执行lua脚本时，报错EvalSha is not supported in cluster environment，不支持cluster。
代码：
代码语言：javascript复制 @Test
public void test4() throws Exception {
DefaultRedisScript script = new DefaultRedisScript();
script.setScriptSource(new StaticScriptSource("redis.call('SET', KEYS[1], ARGV[1]); return ARGV[1]"));
script.setResultType(String.class);
Object result = redisTemplate.execute(script, Arrays.asList("test_key1"), Arrays.asList("hello,key1"));
System.out.println(result);
}
报错信息：

但是redis是支持lua脚本的，只要拿到原redis的connection对象，通过connection去执行即可：
代码语言：javascript复制 @Test
public void test5() throws Exception {
List<String> keys = new ArrayList<String>();
keys.add("test_key1");
List<String> args = new ArrayList<String>();
args.add("hello,key1");
String LUA = "redis.call('SET', KEYS[1], ARGV[1]); return ARGV[1]";
//spring自带的执行脚本方法中，集群模式直接抛出不支持执行脚本异常，此处拿到原redis的connection执行脚本
String result = (String)redisTemplate.execute(new RedisCallback<String>() {
public String doInRedis(RedisConnection connection) throws DataAccessException {
Object nativeConnection = connection.getNativeConnection();
// 集群模式和单点模式虽然执行脚本的方法一样，但是没有共同的接口，所以只能分开执行
// 集群
if (nativeConnection instanceof JedisCluster) {
return (String) ((JedisCluster) nativeConnection).eval(LUA, keys, args);
}
// 单点
else if (nativeConnection instanceof Jedis) {
return (String) ((Jedis) nativeConnection).eval(LUA, keys, args);
}
return null;
}
});
System.out.println(result);
}
输出： hello,key1
