<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy --> - [x] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate. ### Environment * Dubbo version: 3.1.9 * Operating System version: Windows * Java version: 11.0.18 ### Steps to reproduce this issue 1. 正常启动一个普通springboot+dubbo应用，使用默认的logback且未配置日志选项 2. 使用 QoS 命令 `loggerInfo` 查询日志配置 3. 未正确返回结果，且应用控制台抛出NPE ```bash telnet localhost 22222 ___ __ __ ___ ___ ____ / _ \ / / / // _ ) / _ ) / __ \ / // // /_/ // _ |/ _ |/ /_/ / /____/ \____//____//____/ \____/ dubbo>loggerInfo loggerInfo :fail to execute commandContext by null ``` ### Expected Behavior <!-- What do you expect from the above steps？--> 正常查询应用的日志配置 ，如果某些参数未配置则提供默认值（如 Log level: INFO） ### Actual Behavior <!-- What actually happens? --> If there is an exception, please attach the exception trace: ``` 14:15:36.417 logback [qos-worker-3-1] INFO o.a.d.q.c.DefaultCommandExecutor - [DUBBO] [Dubbo QoS] Command Process start.

Current Adapter: [slf4j]. Log level: INFO ``` -- This is an automated message from the Apache Git Service.
