使用jedis 实现redis消息订阅是一个独立的线程(长连接与Redis server通讯), 在实际应用场景下,Redis服务暂时中断是可预见一种异常,必须处理,这时就必须实现重连(reconnect...下面是我的应用中实现subscribe reconnect的逻辑。...logger.error("Subscribing failed. {}", e.getMessage()); // 延时后再试 try { Thread.sleep(RECONNECT_DELAY_MILLS
If the connection has gone down and auto-reconnect is enabled an attempt to reconnect is made. ......Auto-reconnect is disabled by default....To enable it, call mysql_options() with the MYSQL_OPT_RECONNECT option",也就是说,它实际上还依赖于MYSQL_OPT_RECONNECT...解决办法是调用 mysql_options ,将MYSQL_OPT_RECONNECT设置为1: char value = 1; mysql_options(mysql, MYSQL_OPT_RECONNECT...,然后调用了第二个reconnect,这个reconnect会调用mysql_init()以及mysql_real_query()执行一些初始化的命令,于是又回到cli_advanced_command

下面是一种常见的实现方式: // 设置重连时间间隔(单位:毫秒) const RECONNECT_INTERVAL = 1000; // 设置最大重连次数 const MAX_RECONNECT_TIMES...(); }; } // 尝试重连 function reconnect() { if (reconnectTimes >= MAX_RECONNECT_TIMES) { console.log...= 1000; // 设置最大重连次数 const MAX_RECONNECT_TIMES = 3; let reconnectTimes = 0; let ws;...console.log(`收到消息:${message.data}`); // } }; } // 尝试重连 function reconnect...() { if (reconnectTimes >= MAX_RECONNECT_TIMES) { console.log('重连失败');
console.log('WebSocket 连接错误'); // 尝试重连 _this.reconnect...console.log('WebSocket 连接已关闭'); // 尝试重连 _this.reconnect...return; } if (_this.websocket.RECONNET_TIMES >= _this.websocket.MAX_RECONNECT_TIMES...它会在 WebSocket 连接关闭时被调用,在控制台输出 'WebSocket 连接已关闭',并且会调用 reconnect 方法进行重连。...reconnect:WebSocket 重连方法。
reconnect 属性,是否重连。当 Channel 未连接需要连接,或者 Channel 断开需要重连时,标记 reconnect = true 。后台线程会根据该标识进行连接( 重连 )。...代码如下: 第 99 行:当 reconnect = true 时,才执行连接( 重连 )。...第 118 至 121 行:连接成功,不标记 reconnect ,这样,下次执行 #run() 方法会继续重连。...第 124 至 126 行:连接异常,不标记 reconnect ,这样,下次执行 #run() 方法会继续重连。...若是,标记 reconnect = true ,等待后台进行重连。 3.
