Apache Log4j安全漏洞-2.17.0 jar未将查找值加载到log4j2中。xml

Question

根据ApacheLog4J安全漏洞指南，我在应用程序中更新了2.17.0JAR。

未生成升级后日志文件。

Spring version : 5.3.13
Log4j version : 2.17.0
java : 1.8

请参阅下面给出的日志4J2。xml

我使用下面给出的查找，以便从表中获取日志文件名、日志文件路径、日志级别、存档天数。

import org.apache.logging.log4j.core.LogEvent;
import org.apache.logging.log4j.core.config.plugins.Plugin;
import org.apache.logging.log4j.core.lookup.AbstractLookup;
import org.apache.logging.log4j.core.lookup.StrLookup;
import org.appconfig.properties.ApplicationProperties;
import org.springframework.util.StringUtils;

@Plugin(name = "appconfig", category = StrLookup.CATEGORY)
public class AppLog4JConfigDatabaseLookup extends AbstractLookup {

    public String lookup(final LogEvent event, final String key) {
        
        
        if (key.equalsIgnoreCase("filename")) {
            return ApplicationProperties.getLogFilename();
        }
        if (key.equalsIgnoreCase("log_path")) {
            return ApplicationProperties.getLogPath();
        }
        if (key.equalsIgnoreCase("file_level")) {
            return ApplicationProperties.getFileLogLevel();
        }
        if (key.equalsIgnoreCase("console_level")) {
            return ApplicationProperties.getConsoleLogLevel();
        }
        if (key.equalsIgnoreCase("app_name")) {
            return ApplicationProperties.getAppName();
        }
        if (key.equalsIgnoreCase("archive_days")) {
            return ApplicationProperties.getLogArchiveDays();
        }
        
        return key;
    }
}

请参考下面给出的服务类别。

public class LoaderJob extends SchedulerAdapterJob {
    @Autowired
    private FileLoaderJob fileLoaderJob;
    
    private static final Logger LOGGER = LogManager.getLogger(LoaderJob.class);
    @Override
    public void executeJob(JobExecutionContext jobExecutionContext) {
        ThreadContext.put("routingLogFile","LOADER_LOGS");
        try {
            fileLoaderJob.execute();        
            
        }
        catch (Exception e) {
            LOGGER.error("Exception in  "+getJobName()+" : "+ e.getMessage());
            throw e;
        }
        finally {
              ThreadContext.remove("routingLogFile");
        }       
        
    }

}

它在2.16.0中运行良好，在2.17.0中不起作用。任何解决方案都将不胜感激。

根据Apache指南，您应该在模式中添加两个$routes。但是在你的log4j2中。xml只包含一个
