Log4j设置个别类的日志级别

标签: java log4j

我在这个软件包中包含了mypack和MyClass。我想仅记录此类的INFO级别并尝试使用log4j.properties进行设置:

log4j.debug=true
log4j.rootLogger=ALL, debugLogfile
log4j.rootCategory=, debugLogFile
#log4j.category.mypack =INFO
log4j.logger.mypack =INFO

    log4j.appender.debugLogfile=org.apache.log4j.RollingFileAppender
    log4j.appender.debugLogfile.File=mylog.log
    log4j.appender.debugLogfile.Threshold=ALL
    log4j.appender.debugLogfile.MaxFileSize=100MB
    log4j.appender.debugLogfile.MaxBackupIndex=4
    log4j.appender.debugLogfile.layout=org.apache.log4j.PatternLayout
    log4j.appender.debugLogfile.layout.ConversionPattern=%d %-4r [%t] %-5p %c %x - %m%n

不幸的是,类也记录了DEBUG级别。有什么问题?

我以这种方式创建记录器:

public final Logger log = Logger.getLogger(getClass());

您也可以选择使用XML文件。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration PUBLIC 
"-//log4j/log4j Configuration//EN" "log4j.dtd" >
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

    <!-- console -->
    <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
        <param name="threshold" value="ALL" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="conversionPattern"
                value="%d{yyyyMMdd-HHmmss.SSS} %-5p (%c.java:%L).%M - %m%n" />
        </layout>
    </appender>

    <!-- categories -->
    <category name="org.hibernate">
        <priority value="WARN" />
    </category>
    <category name="org.hibernate.type">
        <priority value="TRACE" />
    </category>
    <category name="mypack">
        <priority value="INFO" />
    </category>

    <!-- root -->
    <root>
        <priority value="ALL" />
        <appender-ref ref="STDOUT" />
    </root>
</log4j:configuration>

使用您的设置,文件的追加器:

<!-- file -->
<appender name="ROLLOUT" class="org.apache.log4j.RollingFileAppender">
    <param name="file" value="mylog.log" />
    <param name="maxFileSize" value="100MB" />
    <param name="maxBackupIndex" value="4" />
    <param name="threshold" value="ALL" />
    <param name="encoding" value="UTF-8" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="conversionPattern" value="%d %-4r [%t] %-5p %c %x - %m%n" />
    </layout>
</appender>

您需要在packagelogger级别设置Category Logger访问权限,以便尝试以下操作:

# make default and debugLogFile both as root category
log4j.rootCategory=, debugLogFile

# set package wide logger Level (via Category, older way)
log4j.category.mypack=INFO

# OR set package wide logger Level (via Logger, newer way)
log4j.logger.mypack=INFO

# an example of turning all apache package logs to WARN
log4j.category.org.apache=WARN

试试

  

log4j.rootLogger = DEBUG,stdoutdebugLogfile
  log4j.logger.mypack = INFO

而不是

  

log4j.appender.debugLogfile.mypack = INFO

为整个应用设置DEBUG等级,为'mypack'包设置INFO。

据我记得你可以像这样指定它

  

log4j.logger.com.proj.eqd.exo.http.filter = INFO

答案 4 :(得分:0)

尝试添加:

log4j.logger.mypack =INFO, debugLogfile
log4j.additivity.mypack = false
log4j.rootLogger=ALL, debugLogfile

您的类正在使用rootLogger的配置以及它自己的配置。通过添加additivity参数,您将避免它。

希望它有所帮助。
