这四个词都是日志级别(log level),用于指示日志信息的重要程度和严重程度。一般来说,日志级别从低到高分别是 debug,info,warn,error。
1. debug:用于输出程序运行过程中的详细信息,通常只有在调试程序时才需要输出该级别的日志信息。
2. info:用于输出程序正常运行过程中的信息,例如程序启动信息、请求处理信息等。
3. warn:用于输出程序运行过程中的警告信息,例如程序使用了过时的方法、参数等。
4. error:用于输出程序运行过程中的错误信息,例如程序抛出了异常、请求处理失败等。
在实际应用中,可以根据需要设置日志级别,只输出需要的信息,避免日志信息过多影响程序性能。

These are different levels of severity for log messages in a software application:
1. Debug: These messages are used for debugging or troubleshooting purposes. They are usually used during development and are not shown in production environments.
2. Info: These messages provide information about what is happening in the application. They are usually used to track application events and are considered useful for developers.
3. Warn: These messages indicate potential issues that may cause errors in the application. They are usually used to alert developers about issues that need attention.
4. Error: These messages indicate errors that have occurred in the application. They are usually used to alert developers about issues that need to be fixed.
5. Fatal: These messages indicate critical errors that have caused the application to stop functioning. They are usually used to alert developers about issues that need immediate attention.
debug、info、warn、error
debug:调试信息,通常用于开发阶段,用于输出程序的运行状态、变量值等信息,帮助开发者定位问题。
info:信息提示,通常用于输出程序的正常运行状态,比如程序启动、请求处理完成等。
warn:警告信息,通常用于输出程序的潜在问题,比如接口返回异常、参数不合法等。
error:错误信息,通常用于输出程序的严重问题,比如程序崩溃、数据库连接失败等。
