这个警告表示在使用log4j进行日志记录时,没有找到适当的appender进行配置。要解决这个问题,您可以按照以下步骤进行操作:
1. 确保您的项目中包含了log4j的相关依赖,例如log4j的jar文件。
2. 确保您的项目中存在一个正确配置的log4j.properties文件。您可以按照引用中的示例配置文件进行设置,其中包括指定log文件的路径、日志级别和格式等内容。
3. 将log4j.properties文件放置在src目录下,以确保它能够被正确加载和使用。
请确保按照上述步骤进行配置,这样您就可以解决这个警告了。

这些警告信息通常表示log4j系统没有正确初始化或配置,导致找不到合适的appender(日志输出目标)来处理日志消息。警告信息中提供的链接可以提供更多关于no appender的详细信息。
为了解决这个问题,你可以按照以下步骤进行操作:
1. 确保你的log4j配置文件正确配置。可以参考log4j官方文档中的配置示例。
2. 确认你的应用程序使用了正确的log4j配置文件。
3. 检查log4j的class路径是否正确设置,确保相关的依赖包正确引入。
4. 检查应用程序的日志记录器是否正确使用了log4j。确保在代码中正确引入了log4j的Logger类,并使用正确的日志记录器名称。
log4j:WARN No appenders could be found for logger (org.apache.flume.node.PollingPropertiesF
log4j:WARN No appenders could be found for logger (org.apache.flume.node.PollingPropertiesFileConfigurationProvider).
This warning message indicates that the log4j framework was unable to find any appenders configured for the specified logger. An appender is responsible for outputting log messages to a specific destination, such as a file, console, or database.
To resolve this issue, you need to configure an appender for the logger mentioned in the warning message. This can be done by adding an appropriate appender configuration to your log4j configuration file. The configuration file is typically named log4j.properties or log4j.xml and should be present in your application's classpath.
Here is an example of a basic appender configuration for writing logs to a file:
```
log4j.rootLogger=INFO, file
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=/path/to/log/file.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d [%t] %-5p %c - %m%n
```
In this example, the `log4j.rootLogger` sets the logging level to INFO and associates it with the `file` appender. The `file` appender is configured to write logs to the specified file path (`/path/to/log/file.log`) using the specified layout pattern.
Make sure to adjust the file path and other settings according to your requirements. Once you have added the appender configuration, restart your application, and the warning should no longer appear.
