Log4j 意外的額外日志

Question

我的日志 output 充滿了我不應該看到的 UNEXPECTED EXTRA 信息。 我剛剛將 Log4j 添加到我公司的 Java 項目中，這正在發生。

文件：log4j.properties

log4j.rootCategory=info,console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.target=System.out
log4j.appender.console.immediateFlush=true
log4j.appender.console.encoding=UTF-8
#log4j.appender.console.threshold=info

log4j.appender.console.layout=org.apache.log4j.PatternLayout
# log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd'T'HH:mm:ss.SSSZ} %p %m%n
log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd'T'HH:mm:ss.SSSZ} %p %m%n

文件：Main.java

    public static void main(String[] args) throws Exception {

        File log4jPropertiesFile = new File("log4j.properties");
            if (log4jPropertiesFile.canRead()) {
                    PropertyConfigurator.configure(log4jPropertiesFile.getAbsolutePath());
                } else {
                    System.out.println("ERROR: Can't read log4j properties file.");
                    Properties log4jProps = new Properties();
                    log4jProps.put("log4j.rootLogger", "OFF");
                    PropertyConfigurator.configure(log4jProps);
                }
                Main.logger.info("Logging started");

        DirectoryService directoryService = new DefaultDirectoryService(); // THIS LINE IS THE START OF THE PROBLEM
        Main.logger.info("Starting program...")

當此行執行時：

DirectoryService directoryService = new DefaultDirectoryService();

我看到很多 output。 如下所示：

這些在我的日志中沒有任何內容。 盡我所能告訴我，我正在通過 DirectoryService object 從一些 Apache 庫中獲取日志記錄 output？

我不明白怎么做，我想禁用該行為，以便我的日志保持干凈。 如果我在這里禁用“控制台”，我最終不會看到其他預期的 output。

#log4j.rootCategory=info,console
log4j.rootCategory=info 

Answer 1

您應該發現這些日志是從哪些包生成的，因此您可以在轉換模式中添加“%c{10}”，以便在日志消息之前打印這些包。 然后您可以禁用特定包的日志或更改日志級別，例如

log4j.logger.com.foo.bar=ERROR
