如何禁用日志記錄調用路徑

Question

我想禁用log4j中記錄所有被調用的類/方法路徑的部分。 例如...

我想成為...

目前我還沒有配置log4j屬性文件。 我想保持INFO按原樣發送到stdout ，但只是避免使用這些方法調用日志。

更新

我已經創建了一個log4j.properties文件，但是我找不到任何設置來禁用方法調用的日志記錄。

注意; 我不是要改變日志消息的“格式”，而是完全禁用方法調用的記錄。

log4j.rootLogger=INFO, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %t %c:%L - %m%n

#prevent "no appenders" warning despite having appenders - http://stackoverflow.com/a/15912258/197606
log4j.category.org.jboss.logging=INFO, stdout

#log4j.category.org.springframework=DEBUG,stdout
log4j.category.com.model.entity =DEBUG,stdout

Answer 1

那些不是log4j調用。 你所看到的是默認的java.util.logging模式（到stderr）。 所以你需要適當地配置java.util.logging。 請參見http://tutorials.jenkov.com/java-logging/configuration.html

Answer 2

如果您使用PatternLayout配置Appender，則應刪除使用完全quallified名稱輸出調用方法的%l 。 你的布局應該是這樣的：

PatternLayout layout = new PatternLayout("%-5p %m");//Level and Message

但是我建議在某種時間戳上添加一些：

%d{dd MMM yyyy HH:mm:ss,SSS}

Answer 3

如果您沒有在外部設置log4j屬性文件，則應用程序中的某個組件將以編程方式配置它。 在任何情況下，您都需要使用您真正想要的內容覆蓋現有的任何當前配置。 最簡單，最易於管理的方法是創建一個有效的屬性文件並將其放在類路徑中。 這樣做不僅可以覆蓋現有記錄器的配置，還可以定義新的記錄器。

如果需要，您還可以以編程方式修改Log4J配置。 通過啟動類中的靜態初始化程序最容易完成。 簡單的例子：

public class LogTest {
    private static final Logger logger = Logger.getLogger(LogTest.class);
    static {
        Logger.getRootLogger().getLoggerRepository().resetConfiguration();
        ConsoleAppender console = new ConsoleAppender();
        console.setLayout(new PatternLayout("%-5p %m%n"));
        console.setThreshold(Level.TRACE);
        console.activateOptions();
        Logger.getRootLogger().addAppender(console);
    }

    @Test
    public void testLogging() throws Exception {
        logger.info("I am a simplistic info log message");
        logger.error("I am a simplistic error log message",
                new IllegalArgumentException());
    }
}
