log4js linux下无法生成日志

运行程序时在windows7下可以生成debug.log log.log日志文件，但一模一样代码部署在Linux却无法生成日志文件。但程序是正常跑着的，求高手指教。 "log4j": { "appenders": [{ "type": "file", "category": "log-debug", "filename": "./logs/debug.log", "maxLogSize": 204800000, "backups": 10 }, { "type": "file", "category": ["log-info", "console"], "filename": "./logs/log.log", "maxLogSize": 204800000, "backups": 10 }, { "type": "console" }] }
