问题描述

已在我的项目中如下创建了log4j.properties文件，但是未创建日志文件(test-service.log)，而是日志消息记录在catalina.out中. ..

Have created log4j.properties file in my project as below, but the log file(test-service.log) is not getting created instead the log messages are getting logged in catalina.out how to resolve this.......

    log4j.debug=TRUE
    log4j.rootLogger=WARN, R
    log4j.appender.R=org.apache.log4j.RollingFileAppender
    log4j.appender.R.File=/opt/apache-tomcat-7.0.40/logs/test-service.log
    log4j.appender.R.MaxFileSize=1000KB
    log4j.appender.R.MaxBackupIndex=5
    log4j.appender.R.layout=org.apache.log4j.PatternLayout
    log4j.appender.R.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSSS}-%t-%x-%-5p-%-10c:%m%n 

推荐答案

1. 添加 log4j-1.2.17.jar 到WEB-INF/lib.
2. 将log4j.properties移至src目录的根目录.

3. 在您的类中初始化记录器，例如:

1. Add log4j-1.2.17.jar to WEB-INF/lib.
2. Move log4j.properties to the root of your src directory.

3. Initialize a logger in your classes like:

私有静态最终Logger LOG = Logger.getLogger(ClassName.class);

private static final Logger LOG = Logger.getLogger(ClassName.class);
