我有一个使用Jedis API的Groovy脚本。偶尔，Jedis客户端会超时。我知道超时默认设置为2000，可以自定义。但是我想知道是否有办法处理这个异常，以便在没有应用程序崩溃的情况下优雅地处理超时错误。
调用Jedis的代码：
use(TimerMethods) {
// Connect to Redis
Jedis jedis = new Jedis(redisHost, redisPort)
def timer = new Timer()
def task = timer.runEvery(1000, interval * 1000) {
def redisHosts = jedis.lrange(key, 1, -1)
marathonHosts.each {
if (!redisHosts.contains(it)) {
jedis.rpush(key, it)
log.info("Added new host $it for $key in Redis")
}
}
}
}
