如何直接调用log4js

DESC

thinkjs提供的logger级别太少

    TRACE: new Level(5000, 'TRACE', 'blue'),
    DEBUG: new Level(10000, 'DEBUG', 'cyan'),
    INFO: new Level(20000, 'INFO', 'green'),
    WARN: new Level(30000, 'WARN', 'yellow'),
    ERROR: new Level(40000, 'ERROR', 'red'),
    FATAL: new Level(50000, 'FATAL', 'magenta'),
    MARK: new Level(9007199254740992, 'MARK', 'grey'), // 2^53
    OFF: new Level(Number.MAX_VALUE, 'OFF', 'grey')

另外category也被弄没了

constructor(config) {
    this[_logger] = {};
    const logConfig = this.formatConfig(config);
    this.setLogger(logConfig);
  }
...
setLogger(config, category) {
    this.configure(config);
    this[_logger] = log4js.getLogger(category);
  }

所以想直接调用Log4js。

在worker中直接调用如下代码，并不能写入到文件cheese.log中：

const log4js = require('log4js');
log4js.configure({
  appenders: { cheese: { type: 'file', filename: 'cheese.log' } },
  categories: { default: { appenders: ['cheese'], level: 'error' } }
});

const logger = log4js.getLogger('cheese');
logger.trace('Entering cheese testing');
logger.debug('Got cheese.');
logger.info('Cheese is Gouda.');
logger.warn('Cheese is quite smelly.');
logger.error('Cheese is too ripe!');
logger.fatal('Cheese was breeding ground for listeria.');

Start by reproducing the worker example with the shown log4js configuration and inspect the logger setup around the provided constructor and setLogger snippets. Determine why the configured logger does not write cheese.log and clarify whether direct log4js access should preserve categories and levels; done means a documented or tested working path for worker logging.
