javascript - log4js-node 如何将console里的全部信息输出到日志文件里？

Question

问题： 为甚么最上面的两条日志：server listen on 3000,和wdd没有被保存在日志文件里？ 如何才能把这些console信息也保存在日志里？

log4js-node 配置

// log4js config
log4js.configure({
  appenders:[
    {type:'console'},
    {type:'file', filename:path.join(__dirname, 'logs/well-client.log'), category: 'log4jslog'}
  ],
  replaceConsole: true
});
var logger = log4js.getLogger('log4jslog');

...
app.use(log4js.connectLogger(logger, {level: 'info'}));

var log4js = require('log4js');

var levels = ['trace', 'info', 'warn'];
var appenders = [{
    "type": "logLevelFilter",
    "level": 'INFO',
    "appender": {
        "type": "console"
    }
}];
for(var i in levels){
    var level = levels[i];
    appenders.push({
        "type": "logLevelFilter",
        "level": level.toUpperCase(),
        "appender": {
            "type": "dateFile",
            "filename": "/opt/xxx/logs/",
            //目录
            "pattern": "yyyyMMdd-"+level+".log",
            //命名规则，我们是按天，也可以设置为yyyyMMddhh.log，为按时
            "absolute": true,
            "alwaysIncludePattern": true
        }
    });
}

log4js.configure({
    "appenders": appenders
});

log4js.getLogger('xxx');

INFO输出到console,'trace', 'info', 'warn'输出到文件
